AMX NXI-x000 Series manual Setting the CardFrame DIP Switch NI-4000 Only

Connections and Wiring

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 Program 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 theBaud Rate Settings on the Configuration DIP Switch andPRD Mode Settings tables.

3.Reconnect the 12 VDC-compliant power supply to the 2-pin 3.5 mm mini-Phoenix PWR connector.

Setting the CardFrame DIP Switch (NI-4000 Only)

Refer to the Setting the NetLinx Control Card Addresses (NI-4000 Only) section on page 16 for a detailed explanation on this process.

Program Port Connections and Wiring

The Integrated Controllers are equipped with a Program port located on the front of the unit. Use an RS232 programming cable to establish a connection between this Program port to your PC's COM port. This connection provides communication with the NetLinx Integrated Controller. Then you can download NetLinx programs to this on-board Master using the NetLinx Studio v 2.4 software program. Refer to the NetLinx Studio instruction manual for programming instructions. The following table shows the rear panel Program Port connector (male), pinouts, and signals.
