Setting the Configuration DIP Switch (for the Program Port)

Prior to installing the Controller, use the Configuration DIP switch to set the baud rate used by the
Program port for communication. The Configuration DIP switch is located on the front of the Integrated
Controllers.

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 2.4.
By default, the baud rate is set to 38,400 (bps).
Baud Rate Settings on the Configuration DIP Switch
Baud Rate
9600 bps
38,400 bps (default) OFF
57,600 bps
115,200 bps
Note the orientation of the Configuration DIP Switch and the ON position label.
DIP switches 2,3, and 4 must remain in the OFF position at all times.

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.

Normal mode (default) OFF
PRD Mode
The PRD mode prevents the NetLinx program stored in the on-board Master from running when you
power up the Integrated Controller. This mode should only be used when you suspect the resident
NetLinx program is causing inadvertent communication and/or control problems.
If necessary, place the on-board Master in PRD mode and use the NetLinx Studio v 2.4 program to
resolve the communication and/or control problems with the resident NetLinx program. Then download
the new NetLinx program and try again.
