1.1 INTRODUCTION
RTS Systems, Inc. Model CIF612Camera IS0
Electronics is the electronic heart of a special
intercommunications system. This system allows both
conference-line communication and special, isolated
point-to-point communication. The system consists of
Video Control Panels (the VCP6A or
128) and user
stations, camera operator user stations, a Source
Assign Panel (the SAP1626), and the Model CIF612.
Up to 6 video control panels and up to 12camera
interfaces canbe used in the system. This special,
isolating capability is known as video IS0or camera
ISO.
In a production or broadcast setting there arevideo
operators and camera operators communicating on
one or more conference-line communication
charnels. When a video operator wants totalk
privately with a particular camera person, the video
operator pushes a switch on the control panel (the
VCP6A or 12B) corresponding to the camera. This
action removes both parties from the conference
channel and places them on
a completely separate
and isolated channel. Point-to-point communication
is now established between these two people and they
may now carry on a private conversation. Any
combination of up to 12stations may be selected at
the same time. When the conversation is complete,
the video operator again pushes the camera button
and that camera is restored to the conference-line
communication channel.
An additional feature of this system assigns a
particular priority to each video operator's control
panel, either HIGH or LOW. In theory, any video
control panel can IS0any camera at any time. If
another control panel has already selected a camera,
the priority designation comes into play. Control
panels with the same priority assignment can share
the isolated channel, but the HIGH priority control
panel will "take"a given camera line from a LOW
priority panel.
12 DESCRIPTION
The Model CIF612 is a rack-mounted card cage
containing 12slots for the interface and switching
cards. Slots 2 through
7 arewired to accommodate
the CH612dual camera interface circuit cards. Slots
8 through 13 arewired to accommodate the SW612
IS0control/switch cards. Up to six of each type of
card may be used. The first slot on the right and left
sides of the unit are not functional. An extender card
is provided with each unit and is located in one of the
non-functional card slots. You may wish to order a
spare of each type of card and install them in the non-
functional slots to minimize interruption in case of
component failure. The front panel is hinged to allow
easy access. The reverse of the front panel is labeled
with all the circuit card adjustment information.
Each circuit card features on-board power regulalion
and filtering, and anLED which shows power status.
All active cards connect to the motherboard matrix
through gold plated card edge fingerson the back of
the card.
Level and balance adjustments for the unit are located
just behind the hinged front panel. The reverse side
of the front panel contains a legend explainingthe
location and function of all of the controls.
13 POWER REQUIREMENTS
The Model CIF612 requires 14volts AC or 16volts
DC to operate. The unit is shipped with a power
supply which provides the necessary voltage.
1.4 CONNECTIONS
All connections toand from the CIF612 are found on
the back panel. The control panels connect to
50 pin
female microribbon connectors. Each camera's four
wire intercom signal cable connects to a 5-pin male
XLR type connector. A 25-pin D connector provides
connection to the SAP1626 so that each camera may
be assigned one of the non-iso intercom
channels.

ON CARD
The CIF612 card frame has 14slots numbered
1
through 14running from left to right when viewed
fromthe front of the unit. Slots
1 and 14are not
connected to anything and are only used for storage
The extender card is kept in one of these slots.
The card frameis protected by a hinged frontpanel.
Springloaded catches lock the panel in place.
Release the catches and gently lower the panel to
reveal the card slots. The reverse side of the panel
contains a legend explainingthe location and function
of the various controls for the CIF612.
33.1 CH612 CAMERA INTERFACE CIRCUIT
CARDS
Slots2-7 arewired to accept CH612 camera interface
circuit cards. Slot #2 holds the card for cameras
1
and 2. Slot #3 holds the card for cameras 3 and 4,
etc. Up to 6 cards can be used for a total of 12
cameras. When adding CH612 camera cards to
expand the system make sure to insert the new cards
into slots that correspond to their camera numbers.
Each CH612 circuit card has fivemultiturn trimmer
potentiometers for each camera on that card. These
controls govern level and balance adjustment for both
non IS0channels (RTS
TW or program channels)
and IS0channels. The controls arelocated on the
edge of the circuit card facingthe front of the unit.
The first 5 controls govern the 1st (or odd numbered)
camera, and the second set govern the 2nd (or even
numbered) camera.
Onthe bottom edge of each CH612 circuit card is a
lamp which indicates the power status for that card.
When the lamp is illuminated, the card is powered up.
When the lamp is extinguished,power has been
interrupted. If all cards show power interruption,
check the fuse located on the rear panel of the frame
or check the 117VAC main supply. If one card only
shows a fault,check the on board fuse for that card.
For safetyreplace all fuses with the same type and
rating.

332 SW612 CONTROL/ISO SWITCH
CIRCUIT CARDS
Slots8-13arewired to accept SW612 control/ISO
switch board circuit cards. Each circuit card
represents one control panel. Slot
#8 holds the
circuit card for control panel
1, slot #9 holds the card
for control panel 2, etc. When expanding the system
by adding more control stations (up to 6 may be
used), make sure each SW612 circuit card is in the
appropriate slot.
Each SW612 control card contains a trimmer
potentiometer which governs the IS0balance to all
cameras from that control panel. The pot is
numbered R145 and is located in the middle of the
front edge,just above the power indicator lamp. The
lamp which indicates power status works the same
way as the CH612 circuit card lamps.
Each SW612card also contains the jumpers which set
the HIGH or LOW priority designation for that
control panel. Use thejumpers provided with the unit
to set priority for each camera on the card. After
setting priority, make sure to mark the priority
designation on the space provided inside the front
panel.
