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.

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.

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.
