RS485 Daisy Chain
(RS485 devices are also known as ABB Device Comm devices)
Wiring Diagram
VIM1EC meter is connected via RS485 daisy
-
chain network either to a GPS system equipped with Millennium® I
or Pulsar Plus controller or to a Gateway Assembly.
RS485 Network:
1.
RS485 connection to previous RS485 device
•
First VIM1EC connects to either a Gateway or to a GPS system RS485 network.
•
Additional VIM1EC connects to either the previous RS485 device in a network
mastered by either a Gateway Assembly or by a GPS system controller.
2. Gateway Assembly connection for terminating resistor
•
Gateway Assembly with one BDFB
-
install the terminating resistor (TR 450050642)
In Position 1 of the RJ485 adapter on the bracket.
3. RS485 connection to next RS485 device or terminating resistor
•
Gateway Assembly multiple BDFBs or GPS system
-
install the terminating
resistor in the last RS485 device of the chain, into the RS485 port for the
next RS485 device
