Set Modbus Node-ID for each device attached to the gateway
- Set Modbus Node-ID for each of the devices attached to gateway. The Node-ID’s need to be uniquely assigned between 1 and 255.
- The Node-ID that is assigned for each device needs to be documented.
- The Node-ID’s assigned are used for deriving the device instance for BACnet/IP and BACnet MS/TP.
Selecting the desired eld Protocol
Gateway units use the “S” bank of DIP switches (S0 – S3) to select the eld protocol.
- See the table below for the switch settings to select.
- The OFF position is when the DIP switches are set closest to the outside of the box.

BMS Network settings: MAC address, device instance and Baud rate
BACnet MS/TP: Setting the MAC Address for BMS Network
- Only 1 MAC Address is set for gateway regardless of how many devices are connected to gateway.
- Set the BACnet MS/TP MAC Address of the gateway to a value between 1 to 127 (Master MAC Address); this is so that the BMS front end can
nd gateway via BACnet Auto-Discovery.
NOTE: Never set a BACnet MS/TP MAC Address of the gateway to a value from 128 to 255. Addresses from 128 to 255 are Slave Addresses and
can not be discovered by BMS front ends that support Auto-Discovery of BACnet MS/TP devices.
- Set “A” bank DIP switches A0 – A7 to assign a MAC Address to the gateway for BACnet MS/TP.
- Refer to Appendix 1 for the complete range of MAC Addresses and DIP switch settings.
NOTE: When setting DIP switches, ensure that power to the board is OFF.
BACnet: Calculating the default device instance
The device instance value is automatically generated using the following formula:
BACnet device instance = (Device Node ID) + (Default Node Offset)
NOTE: The default node offset is 50,000.
For example, if device A has a node ID of 1 and device B has a node ID of 2, then:
BACnet device instance A = (1) + (50000) = 50001
BACnet device instance B = (2) + (50000) = 50002
To reach a specic BACnet device instance result, refer to the chapter 6.
BACnet MS/TP: Setting the Baud rate for BMS network
DIP switches B0 – B3 can be used to set the eld Baud rate of the gateway to match the Baud rate required by the BMS for BACnet MS/TP.
NOTE: When setting DIP switches, ensure that power to the board is OFF

Enabling Auto-Discovery
The S3 DIP switch is used to both enable Auto-Discovery of known devices attached to the gateway and save the recently discovered conguration.
If the gateway is being installed for the rst time, set the S3 to the ON position to enable Auto-Discovery. The ON position is when the DIP switches
are set clotest to the inside of the box.

Power-Up gateway
BACnet MS/TP: Wiring eld port to RS-485 Network
Connect the BACnet MS/TP RS-485 network wires to the 3-pins RS-485 connector on gateway
as shown below (use standard grounding principles for RS-485 GND):
Pins Device Pins Gateway Pins
1 Pin RS-485 + +
2 Pin RS-485 - -
3 Pin GND SG
4 Power In (+) PWR +
5 Power In (-) PWR -
6 Frame Ground FG
Pins Device Pins Gateway Pins
1 Pin RS-485 + +
2 Pin RS-485 - -
3 Pin RS-485 GND G
Check power requirements in the table below:
See the section 5 for information on connection to BACnet/IP network.

Auto-Discovery: After completion - Turn Off to save conguration
The S3 DIP Switch for enabling Auto-Discovery should have been set in the previous chapter before applying power to the gateway.
NOTE: Do not enable Auto-Discovery when the unit is powered.
When power is applied to a gateway that is set to enable Auto-Discovery, it will take about 3 minutes to complete the discovery of all the RS-485
attached to the gateway (the “TX” led will ash during the Auto-Discovery). Once completed, the “TX” and “RX” leds should ash rapidly, indicating
good communication between discovered devices.
Once the gateway has discovered all the RS485 devices, set the S3 DIP switch to the OFF position to save the current conguration.

6. BACNET MS/TP AND BACNET/IP: SETTING NODE_OFFSET TO ASSIGN SPECIFIC DEVICE INSTANCES
After setting a local PC to the same subnet as the gateway, open a web browser on the PC and enter the IP Address of the gateway; the default
address is 192.168.1.24. If the IP Address of the gateway has been changed by previous conguration, the assigned IP Address must be gathered
from the network administrator (The Web Congurator is shown in the chapter 5).
Node_offset eld shows the current value (default = 50,000).
NOTE: The values allowed for a BACnet Device Instance can range from 1 to 4,194,303
To assign a specic device instance (or range); change the Node_offset value as needed using the calculation below:
Device instance (desired) = Node_offset + Modbus Node_ID
For example, if the desired Device Instance for the device 1 is 50,001 and the following is true:
- Device 1 has a Modbus Node-ID of 1
- Device 2 has a Modbus Node-ID of 2
- Device 3 has a Modbus Node-ID of 3
Then plug the device 1’s information into the formula to nd the desired Node_offset:
- 50,001 = Node_offset + 1
- 50,000 = Node_offset
Once the Node_offset value is input, it will be applied to all devices as shown below:
- Device 1 Instance = 50,000 + Modbus Node_ID = 50,000 + 1 = 50,001
- Device 2 Instance = 50,000 + Modbus Node_ID = 50,000 + 2 = 50,002
- Device 3 Instance = 50,000 + Modbus Node_ID = 50,000 + 3 = 50,003
Click “Submit” once the desired value is entered.
7. HOW TO CLEAR PROFILES
After setting a local PC to the same subnet as the gateway, open a web browser on the PC and enter the IP Address of the gateway; the default
address is 192.168.1.24.
If the IP Address of the gateway has been changed by previous conguration, the assigned IP Address must be gathered from the network administrator
(the Web Congurator is shown in the chapter 5).
At the bottom-left of the page, click the “Clear Proles and Restart” button. Once restart is complete, old proles discovered and/or added via Web
congurator are deleted. Now the unit can be reinstalled.
BACnet: Setting Network_Number for more than one gateway on Subnet
For both BACnet MS/TP and BACnet/IP, if more than on gateway is connected to the same subnet, they must be assigned unique Network_Number
values. On the main Web Congurator screen, update the BACnet Network Number eld and click submit. The default value is 50.

Appendix 2. COMPLIANCE WITH UL REGULATIONS
For UL compliance, the following instructions must be met when operating gateway.
The units shall be powered by listed LPS or Class 2 power supply suited to the expected operating temperature range. The interconnecting power
connector and power cable shall:
- Comply with local electrical code.
- Be suited to the expected operating temperature range.
- Meet the current and voltage rating for gateway.
Furthermore, the interconnecting power cable shall:
- Be of length not exceeding 3.05m (118.3”)
- Be constructed of materials rated VW-1, FT-1 or better.
- If the unit is to be installed in an operating environment with a temperature above 65°C (149°F), it should be installed in a Restricted Access Area
requiring a key or a special tool to gain access.
- This device must not be connected to a LAN segment with outdoor wiring.
Appendix 3. VIEWING DIAGNOSTIC INFORMATION
- Type the IP Address of the gateway into the web browser to connect to the gateway.
- Click on Diagnostics and Debugging Button, then click on view, and then on connections.
- If there are any errors showing on the Connection page, refer to Appendix A.4 for the relevant wiring and settings.
Appendix 4. CHECK WIRING AND SETTINGS
No COMS on Modbus RTU side. If the Tx/Rx LEDs are not ashing rapidly then there is a COM issue. To x this, check the following:
- Visual observations of LEDs on gateway
- Check baud rate, parity, data bits, stop bits
- Check device address
- Verify wiring
- Verify device is connected to the same subnet as the gateway
- Verify the Modbus device was discovered in Web Congurator (Chapter 5)
- Field COM problems:
- If Ethernet protocols are used, observe Ethernet leds on the gateway
- Check dipswitch settings (using correct baud rate and device instance)
- Verify IP Address setting
- Verify wiring
Appendix 5. SECURING GATEWAY WITH PASSWORDS
Access to the gateway can be restricted by enabling a password on the FS-GUI Passwords page – click Setup and then Passwords in the navigation
panel. There are 2 access levels dened by 2 account names:
- The Admin account has unrestricted access to the gateway.
- The User account can view any gateway information, but cannot make any changes or restart the gateway.
The password needs to be a minimum of eight characters and is case sensitive. If the password is lost, click cancel on the password authentication
popup window, and email the password recovery token to support to receive a temporary password from the support team.
Access the gateway to set a new password.
