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 rear of the
NI-4000/3000/2000 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 or and those set through your NetLinx
Studio 2.2. 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.
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 2.2 program to
resolve the communication and/or control problems with the resident NetLinx program. Then
download the new NetLinx program and try again.
