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.
*Factory default setting = Even
*Factory default setting = BACnet/IP

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
NOTE: if Modbus TCP/IP was selected for the eld/BMS protocol, skip this section.
Auto-Discovery is not used for MODBUS TCP/IP.
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.

4. POWER AND RS485 CONNECTIONS
Device connections to gateway
Gateway 6 Pin Phoenix connector for RS-485 Devices:
- Pins 1 through 3 are for RS-485 devices (Use standard grounding principles for RS-485 GND).
- Pins 4 through 6 are for power.
NOTE: Do not connect power until next chapter.
Power-Up gateway
BACnet MS/TP: Wiring eld port to RS-485 Network

FPC – N34 (Typical) 170mA 100mA 80mA
FPC – N34 (Maximum) 240mA 140mA 100mA
NOTE: These values are ‘nominal’ and a safety margin should be added to the
power supply of the host system. A safety margin of 25% is recommended.
NOTE: When setting DIP switches, ensure that power to the board is OFF
Apply power to gateway as shown below. Ensure that the power supply used complies with the specications provided in chapter 1.
- Gateway accepts either 9-30V DC or 12-24V AC on pins 4 and 5.
- Frame GND should be connected.

Auto-Discovery: After completion - Turn Off to save conguration
NOTE: if Modbus TCP/IP was selected for the eld/BMS protocol, skip this section.
Auto-Discovery is not used for MODBUS TCP/IP.
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.
S3 DIP Switch Auto-Discovery Mode S3
Auto-Discovery ON - Build New Conguration On
Auto-Discovery OFF - Save current Conguration Off

Connecting to gateway Web Congurator
After setting a local PC on the same subnet as the gateway (previous chapter), open a web browser on the PC and enter the IP Address of the gateway;
the default address is 192.168.1.24.
NOTE: Below the “Active proles” heading, the proles for connected devices are listed. If no proles are present, then wiring,
baud rate and DIP switch settings must be checked, because there is a problem with device communications. All the
active proles must show the correct Node-ID’s before proceeding.
NOTE: If multiple devices are connected to the gateway, set the Virtual Server Nodes eld to “YES”; otherwise leave the eld
on the default “No” setting.
After setting the local IP address of the gateway, to show the parameters of the connected device, following the screens below.
Select the command “Congure” (1) and the command “Proles Conguration” to enter on the “Conguration Parameters” menù.

The Active proles section lists the currently active device proles, including previous Web Congurator additions. This list is empty for new
installations, or after clearing all congurations. To add an active prole to support a device, click the Add button under the Active Proles heading.
This will present a drop-down box underneath.The Current prole column that lists all the available proles.
For every device that is added, assign a unique Modbus Node-ID. This specication must match the device’s network settings.
NOTE: If multiple devices are connected to the gateway, set the BACnet Virtual server nodes eld to “Yes”; otherwise leave the eld on the default
“No” setting (3).
Once the Prole for the device has been selected from the drop-down list, enter the value of the device’s Modbus Node-ID which was assigned in set
modbus node - ID. Then press the “Submit” button to add the Prole to the list of devices to be congured.
Repeat this process until all the devices have been added. Completed additions are listed under “Active Proles” as shown in the following gure.

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 START THE INSTALLATION OVER: CLEARING 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 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, all past proles discovered and/or added via Web
congurator are deleted. The unit can now 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.
