Thermocouple: When wiring the thermocouple, x is the same number. For example, a
thermocouple is wired to A1+ and A1-.
Set the MultiHop Radio (Slave) ID
On a MultiHop radio, use the rotary dials to set the device’s MultiHop Radio ID.
Modbus Slave IDs 01 through 10 are reserved for slaves directly connected to the host (local I/O). Polling
messages addressed to these devices are not relayed over the wireless link. Use Modbus Slave IDs 11 through
60 for MultiHop master, repeater, and slave radios. Up to 50 devices (local slaves and remote slaves) may be
used in this system.
With the left dial acting as the left digit and the right dial acting as the right digit, the MultiHop Radio ID can be
set from 01 through 60.
MultiHop Configuration Software
Use Banner’s MultiHop Configuration Software to view your MultiHop radio network and configure the radio and its I/O.
The software connects to a MultiHop master radio using one of four methods.
• Serial; using a USB to RS-485 (for RS-485 radios) or a USB to RS-232 (for RS-232
radios) converter cable.
• Modbus TCP; using an Ethernet connection to an Ethernet radio master.
• Serial DXM; using a USB cable to a DXM Controller to access a MultiHop master
radio.
• TCP DXM: using an Ethernet connection to a DXM Controller to access a MultiHop
master radio.
For MultiHop DX80DR* models, Banner recommends using BWA-UCT-900, an RS-485 to USB adapter cable with a wall plug that can power your 1
Watt MultiHop radio while you configure it. The adapter cable is not required when connecting to a DXM Controller.

The easiest way to configure a MultiHop radio is to use the MultiHop Configuration Tool. This software tool allows you to configure each input and
output, including setting the type of thermocouple. You may also use Modbus commands to configure the inputs. For more information on using
Modbus commands, refer to the MultiHop Product Manual (p/n
) or the MultiHop Register Guide (p/n
). Both manuals are available for
download from Banner Engineering's website (
