The network consists of a Master device and can contain up to 32 Slave devices. Maxi-
mum length is 1200 m. The number of Slave devices and network length can be in-
creased by using RS485 interface repeater. 

Devices are connected to a network according to linear (bus) topology. It means that the 
line goes from the first device to the second one, from the second one to the third one, 
etc. Star connection and spur lines are not allowed. 

Line reflections always occur at each of the two ends of the bus (the first and the last 
node). The higher the data transmission rate, the stronger the reflections are. A terminat-
ing resistor is needed to minimize reflections. 150 ohm (0.5 W) resistor can be used as a 
line termination. 

The TRM210 can only be used as a Slave device. PLC, computer with SCADA software 
or device can be used as a Master device. 

To establish the communication via Modbus see section 7.6. 

1.4
