CAMERA CONNECTIONS

The front panel

thumbwheel switches tie the camera outputs to one

of 15 buses.and The camera thumbwheel switch out-

puts are available on a rear panel 25-pin female "D"

connector.

"D"

con-

nector.

Note that the lower row of camera thumbwheel

switches, labled [CH 21, select the channel that

be isolated by the VIEW.

Thumbwheel switches S1-S12 select the channels for

cameras 1-6. Odd numbered switches are the upper

row and select the camera's intercom channel

Even numbered switches are lower row and select the

camera's intercom channel 2.

Output from these first 12 switches connects to rear-

panel D connector J8.

PROGRAM CHANNEL DESCRIPTION

(See SD3871 in Section

The three program channels have identical circuitry.

Program

will

used as an example. Program

enters through rear-panel XLR-3-31 connector, J105.

Capacitors C1 and

prevent direct current from

damaging the transformer, TI,

a cable carrying DC

is accidently connected to the program inputs.

The transformer,

TI, converts the

800

ohm balanced

input to a

200

ohm unbalanced line. The resistor, R1,

establishes the

200

ohms. The

200

ohm unbalanced

line

can

also serve as a "dry" RTS Systems

bus

BOP220 DESCRIPTION

(See SD

Section

Two-wire intercom audio plus 32 volts DC from the

SAP1626 connects to the BOP220 at 5121 and 5122

male 50-pin micro-ribbon connectors.

The

micrarib-

bon connectors are wired to the 20 XLR-3-32 type

male output connectors on the BOP220.

or bus selected by the upper row of switches on the

SAP1626, and

a channel selected by the bot-

tom row of switches on the SAP1626, The

"EXTERNAL OUTPUT" number of the XLR-3-32

connectors corresponds to the column numbers on

the SAP1626. Thirty two volts DC may appear on

XLR-3-32, pins 2 and 3, referenced pin

To operate

User Stations, pin 2 must have

18 to +32 volts

DC on it with reference to pin

(common). The ex-

ception to this rule are
