USB A to 4-Pin Captive Screw Terminal Wiring
(continued)
To wire the USB connector on this AAP/MAAP:
1. Cut the Type B connector from a standard USB cable (A-to-B or A-to-mini-B). Strip away
about 0.5” (1.3 cm) of the cable jacket to expose the four wires inside.

Printed in the USA.
2. Using an ohm tester, check which wire corresponds to pins 1, 2, 3,
and 4. (For reference, see the figure on the right.) Typical USB wiring
assignments are: red for pin 1, white for pin 2, green for pin 3, and
black for pin 4.
3. Attach the wires in the correct order to the captive screw connector.
(For reference, see the figure on the other side of this card).
Make sure to test the wires (see step 2) before attaching them to the captive
screw connector and/or putting the AAP/MAAP into use. Extron is not
responsible for equipment damage or faulty operation due to improper wiring.
