Communication
4.5.1
RS485
For remote control and communication with a host system the TMCM-1110 provides a two wire RS485 bus
interface. For proper operation the following items should be taken into account when setting up an RS485
network:
1.
BUS STRUCTURE
:
The network topology should follow a bus structure as closely as possible. That is, the connection
between each node and the bus itself should be as short as possible. Basically, it should be short
compared to the length of the bus.
