RECmax-CVM

Instruction Manual

 7.- RS-485 COMMUNICATIONS

RECmax-CVM

 devices feature one RS-485 communications port� The device has uses the 

MODBUS 

RTU

 communications protocol as the standard protocol�

 7�1�- CONNECTIONS

The RS-485 cable must be wired with twisted pair cable with mesh shield (minimum 3 wires), with a 

maximum distance between the 

RECmax-CVM

 and the master device of 

1200 

 metres�

Up to 32 

RECmax-CVM

 devices can be connected to this bus�

Use an intelligent RS-232 to RS-485 network protocol converter to establish the communications with 

the master device�
