INSTALLATION

2.1 MECHANICAL INSTALLATION

The Model SAP1626 mounts in a standard 19 inch

rack, in a space two rack units high (3.5 inches). The

BOP220 should be mounted in the same rack as the

SAP1626 behind the SAP1626.

ELECTRICAL INSTALLATION

2.2.1 ELECTRICAL INSTALLATION, POWER

The SAP1626 distributes DC power and signals but

no power

required to operate the SAP1626 itself

and there are no power connections.

2.2.2 ELECTRICAL INSTALLATION, SIGNALS

The electrical installation of the SAP1626 requires

one to four four-conductor shielded cables, two f@-

conductor cables, and optionally, a twenty five-con-

ductor cable, and microphone cables.

The one to four four-conductor cables

are

used to

connect one to four TW* Power Supplies, respec-

tively, to the SAP1626 "INTERCOM

CHANNEL

INTERCONNECT" inputs.

The two fifty-conductor cables connect the SAP1626

"EXTERNAL USER STATIONS" "OUTPUTS" to

the BOP220 "CONNECTIONS TO SAP1626, J121,

5122".

The twenty five-conductor cable connects the

SAP1626 "INTERCONNECTION TO VIE306

MODEL

306"

outputs to the VIE306, CIF612, or

di-

rectly to the cameras or optionally, user stations.

The microphone cable connects program sources to

the SAP1626. The SAP1626 program input

impedance

800

ohms. Typical levels to feed into the

program input ranges from OdBm to -lOdBm.

Figure 2-1 shows interconnection of a SAP162.6,

BOP220,l to

Power Supplies**, and a VIE306.

Figure 2-2 shows the

wiring

of a four-conductor

cable**.

Fie 2-3 shows the

wiring

of a twenty-five-

conductor cable.

Fie

2-4

shows

wiring

of a program Input cable.

Figure 2-5 shows how to wire a

User Station ca-

ble to plug into one of the twenty BOP2U) outputs.

Figure 2-6 shows the interconnection of the SAP1626

to a TW/802 Series type intercom system.

Since the SAP1626 has no current limiters, PS50 and

PS60 power supplies may shorten the life of the

thumbwheel switches, but current limiters may be

added to the SAP1626. See Appendix B for a triple

current limiter, circuit assembly. To protect all 12 ac-

tive buses of the SAP1626 requires 4 assemblies.

(Continued, overleaf)

here means the RTS Systems, Two Wire Inter-

com system which combines DC power and unbal-

anced intercom signals. One channel requires two

wires, two channels, three wires, et cetera.

If the TW Power Supply is

PS30 made before

mid 1983, see Appendix A for instructions on how to

connect the PS30 supplies to the SAP1626

Alternatively, program inputs

can

used to monitor op-

tional channels

13,

14, 15. (via a 10 kilohm bridging

amplifier)
