Rockwell Automation MD60 Serial Converter Module - M/N MDCOMM 232 - Manual (Page 25)

Configuring the Serial Converter 4-7
To set the serial port rate:
Step 1. Set DF1 Rate Cfg (03) to the desired rate. Figure 4.7
shows a sample HyperTerminal screen.
Step 2. Reset the Serial Converter. Refer to section 4.6.
Step 3. Set the serial port rate in your software to match the new
serial port rate in the Serial Converter.
4.5 Setting the Fault Action
By default, when DF1 serial communications are disrupted (for
example, a serial cable is disconnected) and control I/O is being
transmitted, the Serial Converter and connected product respond by
faulting. You can set the actions listed in table 4.3.

ATTENTION: The setting of Comm Flt Action (04)
determines the action of the Serial Converter and
connected product if DF1 serial communications are
disrupted. By default, this parameter faults the
product. You can set this parameter so that the
product continues to run. Ensure that the setting of
this parameter does not create a hazard. Failure to
observe this precaution could result in bodily injury
and/or damage to equipment.
