Preparing captive wires

To secure wires in a captive-wire connector:

1.Strip 1/4 inch off the wire insulation for all four wires.

2.Tin 2/3 of the exposed wire.

3.Insert each wire into the appropriate captive-wire connector, according to figures 9 through 12. Insert the wire up to the insulation.

4.Turn the captive screws clockwise to secure the fit in the connector.

If the device is using a separate power supply, do not connect the power wiring from the AXC-232++ to that device.

Using RS-232

When communicating via RS-232, connect the wiring as shown in FIG. 2.
