RS-485 communications
not possible
Is the wiring correct?
Wire correctly.
Are the communications
settings correct?
Check that the communications settings
between this product and the host
system match.
Have you connected fewer
units than the maximum
number of units you can
connect on the same line?
The maximum number of units you can
connect when the protocol is Modbus is
99 units, and when the protocol is
CompoWay/F the maximum is 31. (The
parent device is not included in either of
these numbers.)
Have you set separate
communications addresses
for each circuit?
Make sure the communications
addresses do not duplicate across
circuits when using multi-circuit
metering.
Also, if you connect several of these
products, allocate all of the circuits
different communications addresses.
