UNPACKING
Inspect your packages and equipment for any damage that may have occurred during shipping. Report any
damages to both Sigma Electronics, Inc. and your shipping company. It is the buyer’s responsibility to file a claim
against the shipping company for cost of repair due to shipping damage.
2100 Series frames are shipped fully loaded within the shipping carton. The frame includes the power supply
and required system modules. Remove the fully loaded frame from the carton. The Operator’s Manual is packed within
the same carton as the frame. Systems configured within the SS-2100-6 frame will contain a wall transformer within the
frame’s carton. Control Panels are shipped in separate cartons. The “Wall Mount” power supply for the control panel is
in the same carton as the control panel.
INSTALLATION
All frames and control panels are intended to be mounted in standard 19” EIA equipment racks. To allow frame
installation into a rack, remove the front door. The SS-2100-16+ frame has two screws used to retain the front panel
during shipping. Remove these screws before attempting to mount the frame into a rack. After mounting the frame into
the rack, the front door is held into place by the ball stud and retaining clip hardware.
Frames are designed for maximum ventilation of normal operational heat production. When feasible leave 1RU
(1.75”) space between frames and other equipment within the rack to assist ventilation.
The Master Frame, in multi-frame systems, is the frame containing the SCI-2144 System Control Interface
Module. The position of the Master Frame may be anywhere within reach of the Control Bus interconnect cable
supplied with the system. Ease of wiring the video and audio Source and destination cables may dictate position of
each frame in multi-framed systems.
INTERCONNECT WIRING
After racking the system, the Video and/or Audio signals must be connected to the router modules.
Connections to the SCI-2144 will allow control of the router. All these connections are located at the rear of the frame.
The following information is a guideline to perform the interconnect wiring.
COMMUNICATIONS LINE WIRING
References to the control panel's communication line are typically abbreviated to COMM Line. All of the control
panels are connected to the System Control Interface SCI-2144 via a coaxial cable. There is one COMM Line BNC
connector on the rear of the Master frame that houses the SCI-2144.
Installation of the Master Control panel in a system requires a 75Ω coaxial cable connection between the
COMM Line BNCs. Connect a coaxial cable between the COMM Line BNC of the SCI-2144 and the COMM connection
BNC on the rear of the control panel. Up to 16 control panels may be added to the COMM Line as system
requirements dictate. Additional panels are added by installing BNC “T” connectors in the coax path. Short coax cables
may be used between the “T” and the new panel or the “T” may be connected directly to the panel. Total coaxial cable
paths are recommended to be within 2000 feet. This coaxial path should NOT be terminated in a 75Ω load.
CONTROL BUS WIRING
Systems with multiple frames use an SLV-2126 module or SLC-2102 kit to transfer the control data between
frames. The control data transfer modules interface via a ribbon cable with 9 Pin D-type connectors. There are two 9
Pin connectors on each card. Either connector may be used. The interface cable supplied is 18 inches in length. Frame
placement within the racks will determine the required length of the bus cable. If the supplied cable does not meet the
site requirements a straight pin to pin 9 Pin Sub-D custom cable may be used.
SERIAL PORT CONNECTIONS
Sigma’s custom RS-232 and RS-422 protocol may be used for external control of the system. This provides a
method to allow computer control, modem control, or other third party control devices to communicate with the SCI-
2144. The 9 Pin D-type Serial I/O connector is used for this purpose. It is located on the rear of the Master frame on the
SCI-2144 (or SCI-1616 in the DVS-1616). The pin assignment and wiring information is provided in the SCI section of
this manual.
