Initial Calibration
Without connecting a Boomer II OEM Modem to the Test Jig, initially
check the calibration of the on-board voltage regulator. (This regulator
supplies the RS232 converter and other on-board circuitry only. It does
not supply power to the modem).
1. Connect the centre pin of the DC jack to the +3.8V power
supply with 2A capability and the external pin to the ground.
2. Adjust the trim pot marked ADJ VCC to make sure the voltage
on the test pin next to the ADJ VCC is 3.3V.
3. Keep all of the switches on the dipswitch in the off position
(except DIP switch 2) for normal modem operation.
Set Up
With the power off,
1. Connect the Boomer II OEM modem to the lower FPC
connector on the test jig using a 30-way FPC cable.
Use the following procedure to insert the cable into the FPC
connector.
a. Lift up the lock lever of the FPC connector by flipping it
up with the nail of your thumb or index finger.
b. Ensure that the cable is inline with the connector and
insert the FPC cable into the connector with the
conducting surface of the cable facing downwards.
c. Press down the lock lever.
