CONFIG DIP Switch
Use the Configuration DIP switch to set the information used by the PROGRAM Port for communication or to
set the on-board Master to
Program Run Disable
(
PRD
) mode.
Baud Rate Settings
Before programming the on-board Master, make sure the baud rate you set matches the communication
parameters set on both your PC’s COM port and those set through your NetLinx Studio v 3.x.
By default, the baud rate is set to
38,400
(bps).
Program Run Disable (PRD) Mode
You can also use the PROGRAM port’s Configuration DIP switch to set the on-board Master to Program Run
Disable (
PRD
) mode according to the settings listed in the table below.
PRD
mode prevents the NetLinx program stored in the on-board Master from running during the device’s
power-up. This mode should be used if the resident NetLinx program is causing inadvertent communication
and/or control problems.
If necessary, place the on-board Master in PRD mode and cycle power, then use the NetLinx Studio v 3.x
program to resolve the communication and/or control problems with the resident NetLinx program. After
doing so, download the corrected program, reset the configuration DIP switch to normal mode, recycle power,
and try again.
To set the CONFIG DIP Switch:
1.
Turn off the power switch on the rear of the unit.
2.
Set the CONFIG DIP switch (refer to FIG. 40).
3.
Turn on the power switch.
