6.5.2 RS-485, cont.
All wiring between the converter’s RS-232C port and the Modbus Option
converter/optical-isolator is included and wired at the factory. RS-485 bus wiring
between a master converter and slave converter(s) and ultimately to the customer side
connections is the responsibility of the customer. Such wiring should be shielded as
depicted in Figure 7 on the previous page.
Each converter/optical-isolator contains terminating jumpers used to link the T1 and T2
terminals to the B and A terminals, respectively, and provide internal terminating
resistances. Install such jumpers as indicated in Figure 7 at the first and last device in
daisy-chained RS-485 bus, but remove the jumpers for any intermediately connected
devices.
A master converter’s Node Id is factory set for 3; a slave converter’s is set for 4. These are
the default values for communication with ASEA Power Systems designed Touch Panel
computers. Additional slave converters can be set for Node Id numbers greater than 4
(5-8 recommended). As ASEA Power Systems uses Node Id numbers 9-13 for GMM
products, use of these should be avoided.
