NI-3101-SIG Signature Series NetLinx Integrated Controller
Connections and Wiring
Setting the Configuration DIP Switch for the Configuration
Port
Prior to installing the Controller, use the Configuration DIP switch to set the information used by the
Configuration Port for communication. The DIP switchsets the starting address (the device number in
the D:P:S specification) for the Control Cards installed in the controller with a range of 1-1536. The
four-pin Configuration DIP switch is located on the rear of the device.
Program Run Disable (PRD) mode
The Configuration DIP switch is used 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 during the
device’s power-up. This mode should only 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 use the NetLinx Studio v 2.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.
Working with the Configuration DIP switch
1.
Disconnect the power supply from the 2-pin PWR (green) connector on the rear of the NetLinx
Integrated Controller.
2.
Set DIP switch positions according to the information listed in the
PRD Mode Settings
table.
3.
Reconnect the 12 VDC power supply to the 2-pin 3.5 mm mini-Phoenix PWR connector.

Think of the PRD Mode (On) equating to a PC’s SAFE Mode setting. This mode
allows a user to continue powering a unit, update the firmware, and download a new
program while circumventing any problems with a currently downloaded program.
Power must be cycled to the unit after activating/deactivating this mode on the
Configuration Port DIP switch #1.
