Wiring Guidelines; Preparing Captive Wires - AMX Computer Control PC Presenter Instruction Manual

Wiring guidelines

The AXR-MSE requires 65 mA @ 12 VDC power to operate properly. The Central Controller
supplies power via the AXlink cable. The maximum wiring distance between the Central Controller
and AXR-MSE is determined by power consumption supplied voltage, and the wire gauge used for
the cable. The following wiring guidelines table lists wire sizes and the maximum lengths allowable
between the AXR-MSE and the Central Controller. The maximum wiring lengths for using AXlink
power are based on a minimum of 13.5 volts available at the Central Controller's power supply.

If the AXR-MSE is installed farther away from the control system than recommended in the above
table, connect a 12 VDC power supply to the two-pin 12 VDC PWR IN connector on the rear panel.

Preparing captive wires

You will need a wire stripper, a soldering iron, solder, and a flat-blade screwdriver to prepare and
connect the captive wires.
1. Strip 0.25 inch (0.64 cm) of wire insulation off all wires.
2. Insert each wire into the appropriate opening on the connector according to the wiring
diagrams and connector types described in this section.
3. Turn the flat-head screws clockwise to secure the wire in the connector.
Do not over-torque the screw. Doing so can bend the seating pin and damage the
connector.
