Test Jig

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 trimpot 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.
