WARNING: Disconnect primary power prior to servicing.

The Up Converter board receives its dc voltages (+/- 15 Vdc and +8 Vdc) from the UDC
interface board via connector J3. The up converter board supplies are listed below.

• +15 Vdc: Input power from UDC interface board via connector J1 pin 1

• -15 Vdc: Input power from UDC interface board via connector J1 pin 3

• 8 Vdc: Input power from UDC interface board via connector J1 pin 5

• An on board regulator produces +5 Vdc from the +15 Vdc supply.

+/-15 Vdc is supplied to the output amplifier from the Up Converter board via J2.

• +15 Vdc is supplied via J2 pin 1.

• -15 Vdc is supplied via J2 pin 3.

• Returns (ground) for the +/-15 volt supplied is via J2 pins 2 and 4.

The +15, -15, and +8 Vdc inputs appear on the up converter board status screen.

Power for the output amplifier is received at J5 from the up converter board via J2. The
power connections for J5 are listed below.

• +15 Vdc is received at J5 pin 1.

• -15 Vdc is received at J5 pin 3.

Returns (ground) for the +/-15 volt supplies are via J5 pins 2 and 4.
