Getting Started
The Fargo SERVER is what is called a “bare board” product and is supplied without a housing. It operates on low voltage; however you need to use simple handling precautions to prevent damage to the circuits. All electronics are susceptible to electrostatic discharge. This high voltage “shock” can permanently damage your device. Before handling the product, you should touch a surface such as a grounded workbench or table. It is also best to handle the device from its edges. If you notice that your chair or clothes often cause static discharges, you must exercise extra caution. The unit is supplied with four rubber feet which keeps the bottom of the board from coming into contact with the surface you put it on. Be careful not to let metal objects, such as screw drivers or hardware, come in contact with the bottom of this product. The board can be mounted on a panel using stand offs and #4 hardware. The mounting holes are connected to the GROUND signal. The SERVER unit is a self-contained web server configured with various input and output circuits. Although the relays are rated for higher voltages, this product is not designed for use at line voltages. You should never use voltages through the SERVER product exceeding 48 volts. IT IS NOT SAFE.
The KODA SERVER is a housed unit with a DIN rail mountable enclosure that can be snapped onto a DIN rail or attached to any flat surface such as a wall or under a counter. KODA 100 has two relays (48VAC@1A), KODA 200 has four relays which can drive 10V 50mA to external devices. The unit is supplied with a DIN Rail mountable enclosure with removable terminal connectors for easy installation. The KODA SERVER can be mounted on a panel or on the wall using the DIN rail mount clip. The removable wire terminal connectors simplify field installation and allow for easy troubleshooting and maintenance: the unit can be removed from the system without disturbing the system wiring.
Wiring the Server
Note: For a diagram showing the location of all connectors on your SERVER referenced in this section, please see the section – Board Layout Reference.
Caution: These units are ground isolated. Always connect so that power loop is only connected to the SERVER unit. Do NOT use external ground connections. Doing so may damage the SERVER or POE originating device.
- Place the unit on a table or bench being careful not to let any metal objects come into contact with the bottom of the circuit board (Fargo Only).
- Connect the 12VDC power supply to a suitable AC outlet and plug the barrel connector into the SERVER at the location labelled “12VDC/POWER”. Alternatively, you may also use POE. At this point the GREEN/Boot LED should come on and start flashing indicating the SERVER is operating and is in the “Bootload Mode”. This mode allows the user to update the server software that is used on the unit. After about 5 seconds, the GREEN LED will go off and the RED LED will start blinking once per second indicating the SERVER is operating in “Server Mode” and is accessible on a network utilizing TCP/IP protocols.
CAUTION: WHEN YOU USE POE NETWORK SWITCH, DO NOT USE THE 12VDC POWER SUPPLY TO POWER THE SERVER AT THE SAME TIME, IT WILL DAMAGE THE BOARD. - Plug an Ethernet cable into the RJ45/NET connector. The “Connection” LED will come on if a 100MHz network is available, otherwise it will remain off and the “Activity” LED should start blinking indicating network activity.
Fargo G2 Relay Connections
There are 8 relays on the FARGO R8 and 4 on the FARGO R4. These are dry contact relays. These units are designed for only low voltage control and should not have a voltage applied to the relay greater than 48 volts. This is for your safety as well as to stay within the parameters of the parts and circuit board design. The relays have 3 terminals labelled NO, C and NC which stand for Normally Open, Common and Normally Closed. When activated, the relay moves the connection from C¬NC to C¬NO. If you want to make a connection when the relay is activated, connect your wires between C and NO. When the relay is activated C and NO will be connected together. If you want to break a circuit when the relay is activated, make your connections to C and NC. When the relay is activated the circuit will be broken (or open)
Koda Relay Connection
There are 2 relays on the KODA 100. The KODA 100 has 2 removable 2 position connectors (1 for each relay) and are simply numbered “1” and “2”. These relays are normally open.
There are 4 relays on the KODA 200. The KODA 200 has 1 removable 8 position connector. Each relay has a “+” connection and a numbered connection. The relays may be set to supply about 10VDC by selecting “+V” on the setting switch (see Board Layout Reference page 29) or set to dry contact DC on the switch. If “+V” is selected then the voltage will be present on the “+” terminal and the numbered terminal is the return. Otherwise, a normally open dry contact exists across the “+” and numbered connection. KODA 100/200 is designed for only low voltage control and should not have a voltage applied to the relay greater than 48 volts. This is for your safety as well as to stay within the parameters of the parts and circuit board design.


Digital Input Connections (Fargo R4 and Koda)
The digital inputs allow the SERVER to detect an external on/off state of a sensor. With this information the SERVER can display whether an input is on or off, count events in a resettable or non-resettable counter, and calculate the frequency (such as for use as a tachometer) or the period of the input. There are two modes of operation for the digital inputs – PULL UP and ISOLATED.
- PULL UP mode connects a 1K resistor to an internal voltage allowing you to use a simple switch (such as a magnetic door switch) across terminals 1 and 2. This when the switch is activated a signal is sent to the input.
- ISOLATED mode allows you to directly drive the SERVER’s optoisolator with an external voltage though an internal 1K resistor. This voltage may be in the range of 5V to 24V supplying a minimum of 2mA or a maximum of 30mA to the optoisolator diode. There is no other internal connection to this voltage so it is an isolated input. Please note, when connecting a 12VDC-¬24VDC circuit to the input, an external resistor (can be provided at request, 2.2k ohm 0.5watt) must be used.
These modes are selected by the switch on the SERVER (see Board Layout Reference page 29) marked ISO and PU for isolated and pull up respectively. These are set at the factory to ISO by default.
Wiring a push button: For distances up to 500 feet, a 20 AWG shielded wire is suitable for wiring a push button. If the distance between the push button and the controller extends up to 5,000 feet, use a 16 AWG shielded cable instead. Keep in mind that longer cable runs are more susceptible to signal interference.
Caution: If you intend to use isolated mode, verify that the input switch is set to ISO before applying an external voltage. Doing otherwise may damage the SERVER or POE originating device.
Analog Input Connections (Fargo R4ADI)
The analog inputs allow the SERVER to read the value of external equipment. There are 2 analog inputs.
For AC current monitoring, use one of the two 3.5mm stereo inputs to interface with a current sensor.
The 2 analog input terminal blocks are connected to non¬-isolated ¬0-5V current sensors which may be connected to a variety of devices such as temperature or pressure sensors. The SERVER provides a ground and power connection so that measurements can be made without external voltage references. You should use a sensor that is isolated so that that it makes no connection to a remote ground. See drawing under Board Reference Layout page 29.
Accessing the Server
Once your SERVER is powered on and connected to the network, it will automatically obtain an IP address via DHCP as long as your router is configured to do so. To connect, enter the IP address into your web browser. This will take you to your SERVER’s landing page. To log in, click the Log In button on the top right of the page. Your browser will prompt you to enter your username and password. By default, these credentials are both set to admin. To find your SERVER’s IP address, see below.
Finding your IP Address with Linortek Discoverer
The Discoverer program will automatically locate your SERVER. The Discoverer is a Java program, and requires Java Runtime to be installed to use this feature. Java can be found here: http://java.com/en/download/index.jsp.
To download the Discover program, please go to: https://www.linortek.com/downloads/support¬programming/
Use of Chrome & Firefox browsers is recommended. Please note: If you prefer to use Internet Explorer, Internet Explorer saves Linortek Discoverer as a Zip file by default. In order to use the Discoverer, you will need to select Save as and rename the file as Linortek Discoverer.jar when you download.
When downloading the Discover program, sometimes you will see a popup warning message depending on your browser security settings, asking if you want to keep or discard this file, please click the Keep button as this is a Java program, and it won’t harm your computer.
Once Discoverer locates your device, it will display:

- IP Address
- Host Name
- MAC Address
- Other Info:
- Blue LED (if on)
- Product Name
- Server Software Revision
- Port Number (If ported)
Click the device you want to use shown on the Discoverer program to launch the SERVER web pages in your browser. Click the Login button on the homepage. The default username/password is: admin/admin. You may change these as you desire or disable this feature in the settings menu.
Connecting your SERVER Directly to Your PC
You can also plug your SERVER directly to your PC if there is no network connection available. If you plug your SERVER into your PC’s Ethernet port it will use the default IP address: 169.254.1.1 unless you have previously configured your SERVER to use a static IP. Enter 169.254.1.1 into your web browser to connect. No internet connection is required. Once configured, you can then install your SERVER where you desired.
Server Configuration
Logging In
Once you have entered the IP address and port number, if set, the Login page will open. This page shows the name of this server which you may change in Configure/Network Config.

This page is static with no background activity and is a useful place to park if you are not using the SERVER and do not want to close the connection.
By pressing LOGIN, you will be asked for your username and password. These credentials will be retained by the browser until the browser is closed. You can disable the password requirement in Settings page. See section page 21.
Home Page
Once your login credentials are entered, you will be redirected to the main page of the application. The Home or Index page displays some of the system information and offers the ability to locate the physical device if it is in an area with others. See list below for description.

- TIME – Displayed along with the day of the week. This time may be set to be in a 12 hour format with AM/PM indicator or 24 hour format.
- DATE – Current date is displayed here.
- VOLTS – Voltage at the board is displayed. This may be useful if the SERVER is powered along with other equipment, voltage variance can be noted. Fargo and Koda servers have an input voltage range of 12-48vDC.
- TEMPERATURE – Temperature on the board is displayed. This display may be either °C or °F. This temperature will be affected by the heat generated by SERVER itself so it will always be slightly higher than ambient temperature.
- LEDs – There are 3 LEDs displayed. The RED LED is the system pulse. This should blink about once per second as long as the server is running. The GREEN LED is used for bootloader options and is generally not visible on the website. The BLUE LED is clickable and you can turn it on and off from this web page. This is useful for locating the device physically should it be in use with other similar units as it will illuminate on the unit to which this web browser is connected. The Discoverer program will also note if the BLUE LED is on. This is often referred to as a “Locate” function.
Services
The Services tab is dynamic and will change depending on the configuration of your server. This is where you can control the inputs, outputs, sensors and other specialty controls.
In/Out or Relays Page
Depending on which SERVER you are using, the first page on the SERVICES tab will be either In/Out or Relays. In/Out has the relay controls and the input controls on one page, while Relays only has the relay controls.
Relay Control
An In/Out page is displayed below. Some relay control pages have 2, 4 or 8 relays displayed. Each relay has a number, in this case 1 to 4.

The State LED shows whether the relay is on or off indicated by GREEN and RED respectively. This icon is clickable to manually control the corresponding relay. Each relay can have a Name as well as identifiers for the Normally Open, Common and Normally Closed connections.
There are four status LEDs that show:
- Email – If an email is to be sent when this relay is switched on/off
- Pulse – If this Relay is set with a pulse width and pulse width multiplier (duration) – see next section for more information
- Sched. – If there is a schedule created in the Tasks page (see page 15) set to automatically trigger this relay.
- Timed – If pulse is set and this relay is activated, the Timed LED will turn red showing the relay is currently operating on a timer.
Click the Edit Icon to edit the controls for the corresponding relay. This will take you to the Set Relay page (see page 11).
Inputs
The In/Out or Inputs page (depending on your SERVER) will display information from each input. The SERVERs have a combination of inputs. The Fargo R4DI has four digital inputs, The R4ADI has, four digital inputs, four analog inputs. The KODA SERVER has two digital inputs.
At the top of each input is a label (ex: DIN 1, AIN 2) specifying whether it is a digital input (DIN) or analog input (AIN) as well as the input number. This label will turn green when the input is enabled. Inside the box will be any display configured from the Set Input page (see page 12 for digital input, page 14 for analog input). A red dot in the lower-left corner indicating the state of a linked relay (if any), will turn green when the linked relay is activated. Finally, an Edit icon in the lower-right corner of the box to edit the corresponding input. This will take you to the Set Digital Input or Set Analog Input page (page 12 or page 14).
Set Relay Page
The SET RELAY page allows you to set various properties pertaining to the Relay.
- Relay Select ¬- The Relay that you are editing (identified by the line on which you clicked the Edit icon on the RELAY page).

- Relay at Location -¬ a number representing the relay or device at the Location
- Send Email ¬- the SERVER can be programmed to send an Email if the relay is turned on or off.

Set Digital Input Page
The Digital Inputs can be set to provide various readouts on using a range of display types. In addition to displaying the input data, you can name the display as well as associate a relay with it. This relay will change from Green to RED as it goes from on to off as well as is clickable to control it. By clicking on the edit pencil icon, you can edit the settings for this input:
- Digital Input Selected - The Digital Input that you are editing (identified by the line on which you clicked the Edit icon).
- Name - You can set a 15-character name for this input. This name goes in the bar at the top of the display.
- Label - Set a 7-character label which is displayed on the actual active display.
- Corrector - Using this field you can add, subtract, multiply, or divide a value before the value is shown on the display page. This is a 2-value corrector with each being separated by a single space character. (ie. “+2, -2, *3, /3”)
- USE - Sets this input to active. Turns the input number indicator to green. It should be noted that when in use the input consumes CPU time and other resources depending on its type. Although all inputs may be active at the same time, it is recommended to turn on only those you want to use.
- Type - The input data can be used to calculate a range of results. You may select:
- State - This is useful for knowing if an input is on or off, like a door switch being on or off.
- CounterNR - This is a non-resettable counter.
- CounterR - This is a resettable counter.
- Frequency - Counts the frequency of an input in KHz (kilo hertz or1/1000 seconds). This could be useful in displaying a tachometer where 60Hz = 1 R.P.M.
- Period - in 1/1000 seconds an input in kHz (milliseconds or1/1000 seconds). This would be useful for measuring timed events.
- Display - This selection lets you change the display type used. You can select:
- Dot - A single dot with the value in the middle. This can be used for State. You can make a dumb indicator by changing the color of the Dot based on the value. The label is under the Dot.
- Values - Displays the Corrected Value with the Label in a box directly below it.
- Meter - This Meter has configurable scale based on the Min/Max values and arcs can be colored per the Color ranges. The Label is displayed within the Meter.
- VBar - Also based on the Min/Max values for the scale and the bar changes color based on the values in the Color ranges.
- Relay L/T - Enter a Relay number here. If it is a local relay it will show GREEN or RED depending if it is on or off. By clicking on it the relay will turn on and off. The name comes from the relay settings page. This may be useful if you want to turn the subject of a display on and off. Any relay can be used on any input and each may be reused for any other input. Adding an L after the relay number (ex: 2L) will link the state of the input to the state of the relay. This is an easy and immediate way to have an input follow the relay. Adding a T after the relay number will trigger the relay to the state of the input. This is an easy and immediate way to have a relay follow the input.
- Command Z/N/I - This field is used for issuing various commands to the Digital Input controller: Z Zero the resettable counter. N Leave the input as Normal. I Invert the input.
- Value - These are Min/Max values used for the display. This is useful for preventing a Meter from going past its end or setting the value of a VBar. This is the Value after the Corrector. The system cannot display a value past Max, so be sure this is at least set to 1.
- Yellow/Red/Green - There are three colors that can be used to further define a display. Set the range of these colors to define a color to the display Value. This is the Value after the Corrector. Note that if you are using a State type you may want to assign RED = From 0 to 0, GREEN = From 1 to 1 and YELLOW = From 2 to 2. Since a State is always either 1 or 0 this will prevent ambiguous information and prevent the YELLOW color from being used. You can select any two colors you like for a State type.

Set Analog Input Page
The Analog Inputs can be set to provide various readouts on using a range of display types. In addition to displaying the input data, you can name the display as well as associate a relay with it.

Since a State is always either 1 or 0 this will prevent ambiguous information and prevent the YELLOW color from being used. You can select any two colors you like for a State type.

Tasks Page
The TASKS page displays the automatic events that can be programmed into the SERVER. You can schedule up to 16 events in the SERVER. These are constructed as IF … THEN statements. In addition, the IF term can have 2 elements (IF a, AND/OR/NOT b … THEN c). This provides a simple to program and powerful way to take advantage of the data acquired by the SERVER. The Tasks page shows you an overview of configured tasks. You can click the dot in the State column to turn a task on or off indicated by a green dot for ON, and a red dot for OFF. To edit or create a task, click the Edit icon to the right of the task line. This will take you to the Set Schedule page detailed in the next section.

Network Configuration Page
Access this page from the Configure dropdown menu. This page allows the configuration of the SERVER’s network settings.
CAUTION: Incorrect settings may cause the board to lose network connectivity. In order to access a device in your network remotely you must PORT the device. This tells your router that information coming in should be sent to a specific device on your network.
- MAC Address – This is a unique MAC address that is assigned to this product at time of assembly. It cannot be altered.
- Host Name – This is a Netbios name at which this unit may be addressed in some networks. It may also appear in your router’s lease directory. It makes a useful place to name your SERVER and appears on the Home page and on the Discoverer.
- Port Number – This becomes part of the IP address and is necessary for Internet access. If this is not set, the SERVER defaults to a port number of 80.
- IP Address – Typically you only change the last group of numbers. If you change this IP address make sure to reserve this IP on your router and no other devices are using this IP address or you may not be able to reach this SERVER. If this happens you may need to Restore Defaults using the push button method.
- Gateway – Typically a router on your TCP/IP network that serves as an access point to your ISP.
- Subnet Mask – A 32-bit number that masks an IP address, and divides the IP address into network address and host address. Just leave it at 255.255.255.0
- Primary DNS – A primary DNS.
- Secondary DNS – A secondary DNS.

Appendix 1
How to Send SSL Emails Using a 3rd Party SMTP Service for Linortek Fargo and Koda Devices
By default, Koda/Fargo devices use non-SSL SMTP email servers. But most of the email servers today have switched to SSL security protocol, there are 3rd party SMTP delivery servers which do not require SSL and can be used. There are a lot of SMTP email service providers in the market. We use SMTP2GO as an example to demonstrate the setting up process. SMTP2GO is free to use with up to 1000 emails/month. To use SMTP2GO, please visit: https://www.smtp2go.com/ .
Step 1. Create the SMTP2GO account.
To create an account simply click on “Sign up”, choose “1K Emails” on the scale, and choose “Free plan” (If you need to send more than 1000 emails per month, select the plan that meet your requirements.)

To create an account on SMTP2GO, a corporate email address will be needed. Free email service such as Gmail or Yahoo will not let you continue. After activating your SMTP2GO account, you need to add a user.
Step 2. Add a user.
The user you create on SMTP2GO, will be the Outgoing mail server when you setup the Fargo/Koda device to send email reports, please make sure your corporation email server will not block the emails if you use free email account such as Yahoo or Gmail to add a user here.
Login to your SMTP2GO account, on the left side menu choose “Settings” > “SMTP Users”, Click on “Add SMTP user” and fill the form.

After the user is added to your SMTP2GO account, it will display the information you need to setup the email notification on your Fargo/Koda devices.

Step 3. Configure the Linortek device.
After you created an account and added a user, login to your Linortek device, navigate to Configure – Email setup page to setup Email notification:
• SMTP Server – Enter the outgoing mail server that you want to use, it’s mail.smtp2go.com in our example.
• Port – This is the port on that server. The SMTP port is 2525 in our example.
• Use SSL – Leave it unchecked when you use 3rd party SMTP server.
• User Name – The username from SMTP2GO when we created a user in previous step.
• Password – The user’s password from SMTP2GO when we created a user in previous step.
• To Address – Enter up to 3 addresses for this email set up. An addressee, a CC and a BC.
• Subject – Subject line of the email header.

As soon as you hit “Save/Test”, the device automatically sends the test email. Please check Junk/Other folder to find it if it is not in Inbox folder.
Step 4. Set the task for automatic Email notifications.
You should be able to receive email notifications for various events from the Fargo/Koda boards at this point. If you need to receive condition logic notification, you can use our condition logic configuration to setup such report. To setup the logic condition report notification, go to Tasks page on your Fargo/Koda device, click the Edit icon of a Schedule. For details of how to create a logic-based event, please refer to the Set Schedule Page on the Fargo/Koda User Manual, which can be downloaded here:
In this sample We will use the Network Hour Meter device as an example for how to receive email reports every day at 11:52am

As soon as all conditions of the task are met, you get the following email:
