Set the communication rate according to your application.
Important: You can also select the communication rate for PRT2 within
your program. The settings you select with PROG1 (page 10 -12) and
PROG2 (page 10 -13) override the jumper setting until the module is
powered down. The settings you select with MODE (page 11 -20)
override both the jumper and the PROG1 and PROG2 settings until the
module is powered down. If you use PROG1, PROG2, or MODE with the
“E” option storage to save the port settings in the user EEPROM, the unit
then powers up with the stored configuration.
