Connections and Wiring

Using the 4-pin Mini-Phoenix Connector For Data With External Power

To use the 4-pin 3.5 mm mini-Phoenix (female) captive-wire connector for data communication and power transfer, the incoming PWR and GND cable from the 12 VDC-compliant power supply must be connected to the AXlink cable connector going to the Integrated Controller. FIG. 4 shows the wiring diagram. Always use a local power supply to power the Integrated Controller unit.

When you connect an external power supply, do not connect the wire from the PWR terminal (coming from the external device) to the PWR terminal on the Phoenix connector attached to the Controller unit. Make sure to connect only the AXM, AXP, and GND wires to the Controller’s Phoenix connector when using an external power supply.

Make sure to connect only the GND wire on the AXlink/PWR connector when using a separate 12 VDC power supply. Do not connect the PWR wire to the AXlink connector’s PWR (+) opening.

DB9 Device Port: Connections and Wiring

FIG. 5 shows the connector pinouts for the rear RS-232/RS-422/RS-485 (DB9) Device Ports.

The NI-700 has two ports whereas the NI-900 only has one available DB9 Device Port.

These ports support most standard RS-232 communication protocols for data transmission. This figure gives a visual representation of the wiring specifications for the RS-232/422/485 Device connectors. Refer to the rear of the unit for more detailed connector pinout information.
