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. 49).
3.
Turn on the power switch.
NOTE:
Consider equating PRD Mode to a PC’s SAFE Mode setting. With PRD mode, you can continue to power a unit, update the
firmware, and download a new program while circumventing any problems with a currently downloaded program. You must power
cycle the unit after activating/deactivating PRD mode on Program Port DIP switch #1.
