Parameter Description
Diagnostic File Reserved for future use.
Baud Rate
Toggles between the communication rate of 1200, 2400, 9600, and 19200.
The default is 19200.
Node Address
This is the node address of the processor on the DH485 network. The
valid range is 1-31. The default is 1.
Max Node Address
This is the maximum node address of an active processor. The valid range
is 1-31. The default is 31.
Token Hold Factor
Determines the number of transactions allowed to make each DH485 token
rotation. Increasing this value allows your processor to increase its DH485
throughput. This also decreases throughput to others on the DH485 link.
The valid range is 1-4. The default is 1. SLC 5/01 and 5/02 processors are
factory set to 1.
