20-Pin Header
The following table lists the pinouts for the 20-pin header:
AXlink
To install the AXlink data/power bus wiring:
1. Strip .25 inch off the wire insulation for all four wires. If the wire is 20 AWG or less, fold the
exposed wire over to obtain a positive connection.
2. Insert each wire into the appropriate opening on the connector. See FIG. 4.
3. Turn the captive screws clockwise to secure the fit. Do not over torque the screw; doing so can
bend the seating pin and damage the connector.
FIG. 5 shows the wiring configuration for AXlink cables.
Be sure that the board input ground is connected to the voltage source ground prior
to applying a voltage to the input.
