Set PRT2 Communication Rate Select Jumper (JW6)

Use JW6 to set the communication rate for PRT2 at power-up.

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.
