CONNECTIVITY
The integral RS485 Serial Port (CN2 on the DRV40 PCB) can be used to
connect directly to
Building Management Systems (BMS)
which operates on a
Modbus RTU
protocol.
See
'Options'
screen for details on how to enable DRV40 for
Modbus
.
Modbus
When configured for Modbus the DRV40 becomes a
Remote Terminal Unit (RTU)
.
When connected directly to a BMS using Modbus RTU, the DRV40 will be assigned
a unique network address which is programmed via the integral DB9 external port.
