Important!
Plug in the 13 pin
connector so the black
wire is in pin one (the top
pin) and two open pins
are left at the bottom for
tamper switch connection.
NOTE:
A chipset upgrade to the XM Inverter Module and/or USM Card may be required; contact Alpha for
more information.
Set the jumpers and calibrate the USM card before making cable connections and applying load.
1. Switch the battery breaker OFF.
2. Remove the Inverter Module from the power supply. See the power supply's technical manual for instructions.
3. Position jumpers and switches as shown below.
First, verify the transponder bears the warning label as shown at right. This indicates the unit is an XP-EDH-A2, and the
jump and switch settings described in this instruction will work properly.
NOTE:
The EDH-A2 calculates Output Voltage using AC Scaling as opposed
to the EDH-A which uses DC Scaling. This requires changes to the
USM card jumper settings and eliminates the need to calibrate the USM
potentiometer.
