Rockwell Automation 20-COMM-B BACnet MS/TP Adapter - Manual (Page 35)

Configuring the Adapter 3-7
The value of Parameter 06 - [Baud Rate Cfg] determines the baud rate
used by the adapter. The Autobaud setting will detect the baud rate used
on the network if another device is setting the baud rate. Your application
may require a different setting.
1. Set the value of Parameter 06 - [Baud Rate Cfg] to the baud rate at
which your network is operating.
Figure 3.5 Baud Rate Screen on PowerFlex 4-Class HIM (22-HIM-*)
2. Reset the adapter (see Resetting the Adapter ) so that the new baud
rate takes effect.
Changes to switch settings or some adapter parameters require that you
reset the adapter before the new settings take effect. You can reset the
adapter by cycling power to the drive or by using Parameter 01 - [Reset
Module].
Set Parameter 01 - [Reset Module] to Reset Module.
