SECTION1: DESCRIPTION AND
SPECIFICATIONS
1.1 DESCRIPTION
GENERAL
TheSAP1626SourceAssignment Panel is
a manuallyoperated matrixswitch. This switch assigns
each of 20 TW* User Station strings to two of fifteen
possible buses. Twelve buses
can distributeboth DC
power and intercom signals. Three buses distribute
intercom signals or program signals. The matrix
switch has the effect of transforming a basic two bus
intercom system to a fifeen bus system. The switch
also assigns six camera intercom stations to a pair of
intercom
/ program buses or twelve camera stations
to a singleintercom
/ program bus.
SAP1626 BUSES There are three kinds of buses in
the SAP1626:
1) two-way two-wire type intercom
buses,
2) DC powered two-way two-wire intercom
buses, and
3) program audiobuses. There are twelve
primary intercom buses and three program or sec-
ondary intercom buses.
All buses allow for two-way
two-wire intercom operation. The twelve primary
buses may also be "powered"buses. The powering
is
accomplished by plugging TW type power supplies
into the SAP1626. The powering allows a
TW inter-
com station to receive power on its channel one wire
(oneof threewires connectingthe
TW user station to
the SAP1626). Most
TW user stations require DC
power to appear across two of the three wires con-
necting it to a system. (The
TW stations that don't
require this DC power either have a
"Local Power"
option or they are a special kind of
TW station.) The
two wires that accept DC power on a
TW station are
the common and [CHannel One] connections. This
means that,
in general, the upper row of switches on
the SAP1626 should
be set only to powered buses.
Up to ten user stationsmay be
in a group of TW user
stations connected to a SAP1626 output. The twenty
outputs discussed above are available on the back of
the SAP1626 on two frfty-conductor connectors, or on
the optional
BOP220 as twenty three-conductor male
XLR type connectors.
PROGRAM BUSES Threeprogram buses allow three
different program sources to
be connected to a
SAP1626.
TW user stations can be assignedthese pro-
grams on their channel two connection (bottom row
of switches on the SAP1626).If
TW user stations are
assigned one of the
program buses with program not
connected, thebus functions
as an intercom bus.
CONNECTING SAP1626 BUSES TO MODEL 802
CIlANNJ3L.S
The twelve primary buses of the
SAP1626 correspond to the twelve balanced channels
of the Model
802 intercom systems and can be inter-
connected using a Model
862 System Interconnect.
CAMERA OUTPUTS / OPTIONAL OUTPUTS In
addition to the twenty outputs discussed above, there
are six additional outputs. These outputs are in-
tended primarily for cameras, but
can be used for ad-
ditional
TW intercom stations or groups of stations.
These six outputs are available on
a twenty-five pin
"DM type connectoron theback of theSAP1626.
Camera output pairs
1 thru 6 are designated fortele-
vision camera intercom. Output connections
can be
made directlyto eachcamera or to theModel
VIE306
Station-IsolateSystem. In the latter, the outputs are
switched and/or processed accordingly and then
routed to the individualcameras.
PACKAGING: SAP1626 The SAP1626 fits into a
standard two unit
high EIA equipment rack. The
front panel contains the thumbwheels used to accom-
plish the matrix switching.
PACKAGING: BOP220 The three rack unit high
BOP220 generally mounts on the rear rails of a rack
panel. BOP220 connectorsare mounted on a recessed
panel allowingspacefor mating connectors and cables
yet not interfering with rack door closing. The
BOP220 connects to the two 50-conductor cables
from the SAP1626 and provides twenty male
XLR-
type 3-pin connectors for direct connection to user
stations.
All external user station lines connect to this
central point.
* TW here refers to the two-wire unbalanced type
intercom system sold by RTS Systems,Inc.

SECTION 2: INSTALLATION
I
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
SAP1626behind the SAP1626.
2.2 ELECTRICALINSTALLATION
2.2.1 ELECTRICALINSTALLATION, POWER
The SAP1626 distributes DC power and signals but
no power
is required to operate the SAP1626 itself
and there areno power connections.
2.2.2 ELECTRICALINSTALLATION, 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 microphonecables.
(3
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" outputsto the VIE306, CIF612, or di-
rectly to the camerasor optionally,user stations.
The microphone cable connects program sources to
the SAP1626. The SAP1626 program input
impedance
is 800 ohms. Typical levelsto feed intothe
program input ranges from OdBm to -lOdBm.
Figure 2-1 shows interconnection of a SAP162.6,
BOP220,l to
4 TW Power Supplies**,and a VIE306.
Figure 2-2 shows the
wiring of a four-conductor
cable**.
Fie2-3 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
TW 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 Seriestype intercom system.
Since the SAP1626has 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 SAP1626requires4 assemblies.

com systemwhich combinesDC power and unbal-

ME306 CONNECTIONS Figure 2-1 shows how to
connect a VIE396 to the SAP1626. This approach
provides two channels of two-wire intercom per
channel. Only the lower set of camera thumbwheel
switches are processed by the VIE306 electronics to
provide station isolate and two wire to four wire
conversion. The upper row of camera thumbwheel
switches appears at the rear panel of the VIE306
unprocessed and
in the two-wire plus DC format.
Two VIE306's may be used for a 12 camera installa-
tion. Thesetwo VIE306's may be connected in one of
two ways.
The frrst way is with special cable
RTS Systems part
number 9020-2976-00. Connections are shown
in Fig-
ure 2-7. This cable sendsthe upper row of CAMERA
thumbwheels, normally [Channel
11 for Cameras 1-6
1, to one VIE306 as Cameras 1-6.The lower row of
CAMERA thumbwheels, which are normally
[Channel21 for Cameras 1-6, to a second VIE306 as
Cameras7-12. The disadvantage of this method
is that
there is only one channel per camera, however
if the
cameras are being operated in the 4wire mode the
second channel
is generallynot used.
The second method, for a 12Camera installation,re-
quires two SAP1626's and two VIEWSas shown in
Figure 2-8. The advantageof this method is that two
channels per camera are available and may be se-
lected via the two rows of thumbwheels.

3.2 OPERATION
To select the channels that camera user stations
will
talk and listen on, turn CAMERAS thumbwheel
switches to the desired channels. The upper
thumbwheel selects channel
1 on camera intercom.
The lower thumbwheel switch selects channel 2 on
the camera intercom. Unlessthe camera user station
is
local powered the channel 1 thumbwheel must be
set to a powered channel, i.e. channels 1-12. Channel
2 may be set to any channel regardless of power,
unless the user station has been modified to accept
power from
a channel 2 connection.. If a VIE306 is
used, channel 2 is the isolated "isoed"channel. Thus
the lower row of thumbwheels
will select the channel
that is interuptedby the
VIE306.
To select the channels that the external (non-
camera) user stations
will talk and listen on, turn the
desired EXTERNAL
USER STATIONSthumbwheel
to the desired channel. EXTERNAL USER
STATIONS numbers correspond directly to the
numbers on the
BOP220 Connector Translation
panel. Unless the external user station is local
powered, channel
1 must be set to a powered
channel,i.e. channels 1-12.
'
Because of electrical current limitations, a maximum
of
30 headset user stations can be assigned to the
same powered channel. This only applies to channel
1 of the user stations (upper row of thumbwheels)
and is because power for the user stations is derived
from channel
1 (see Figure4-1). More than one user
station
can be connected to each SAP1626 output so
it
is possible to exceed this limit. If stations with
speakersor
call lights areused the maximum number
is less. For exact numbers see the relevant Power
SupplyTechnicalManual.
