7 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 thePRD Mode Settings table.
3. Reconnect the 12 VDC power supply to the 2-pin 3.5 mm mini-Phoenix PWR connector.
Configuration Port Connections and Wiring
The NI-3101 is equipped with a low-speed USB connection located on the rear of the unit. Use a standard
USB cable to establish a connection between the device and your PC's USB port. This connection provides
communication with the NetLinx Integrated Controller. From there, configure the on-board Master as needed
for your application.
PRD Mode Settings
PRD Mode Position 1
Normal mode (default) OFF
PRD Mode ON
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.
