Specifications

FRAME:
The DVM-1616/DVS-1616 system is provided in a frame designed for rack mounting. The 1 RU frame provides
mounting tabs for a standard 19 inch EIA rack cabinet. All components are mounted into the frame from the rear of the
unit. This frame does not provide additional card slots for insertion of other 2100 Series modules.
The DAS-21xx and DVS-21xx modules can reside in some of four different frames provided by Sigma Electronics,
Inc. If these modules are purchased as a component of a system, please refer to the SERIES 2100 FRAMES
Instruction Manual. If the module was purchased separately, an existing frame must be present for proper operation.
Sigma would like to emphasize the fact that any of the Series 2100 Digital modules can be combined in a common
frame with other modules and they must be controlled by a separate control module like the SCI-2144.
♦ The SS-2100-2 frame is designed for desktop applications. This frame provides two (2) slots and can therefore
only accommodate the DVS-2144 or DAS-2144 and the SCI-2144 controller module.
♦ The SS-2100-6, 1RU frame is designed for 19-inch EIA rack installations. This frame can accommodate some of
the DAS-21xx and DVS-21xx modules along with the SCI-2144 controller module. It provides six (6) slots for modules.
♦ The SS-2100-12+ frame provides thirteen (13) slots for modules within 3 RU. A redundant power supplies can be
provided within this frame. This frame can accommodate the DAS-21xx and DVS-21xx modules and the SCI-2144
controller module.
♦ The SS-2100-16+ frame is also available for installations in a 19-inch EIA rack. This frame provides seventeen
(17) slots for modules within 3 RU. This frame can accommodate the DAS-21xx and DVS-21xx modules and its SCI-
2144 controller module.
VIDEO WIRING:
The video switch inputs are terminating. If the application requires a looping configuration, use a distribution
amplifier on the input signal to send the source signal to multiple devices. This provides the video source with proper
75Ω termination.
Simply connect the source video cables to corresponding input BNCs on the rear of the video routing frame.
Refer to the sections below to review drawings for input and output layout. Sigma Electronics’ connector layout is
designed to economically maximize performance. The source video cable connects to the video input on the rear panel.
The outputs of the video router connect to destination devices. Some devices may be both source and destination
devices. Connect the source signal from the device’s output to the routers input. The destination's input receives a
signal from the router’s output.
DVS-1616 and DVM-1616
Connectors for wiring of source signals and destination devices are located on the rear panel. The inputs, outputs,
Comm. bus and sync reference input use BNCs. A 9 pin D connector is provided for the SCI RS-232/422 interface on
the DVS-1616 model. The DVM-1616 has a 9 pin D connector for control data from a master frame.
SERIAL DIGITAL VIDEO INPUT: The BNC connectors to the left of center on the rear panel provide the 16 Serial
Digital video inputs. Each BNC is a 75Ω terminated connection.
SERIAL DIGITAL VIDEO OUTPUT: The BNC connectors to the right of center on the rear panel provide the 16
Serial Digital video outputs. Each output utilized requires a 75Ω terminated destination. The unused outputs do not
require a 75Ω load.
SYSTEM CONTROL: There are several methods of configuring system control. Take note that the DVS-1616 is
complete with an SCI. The DVM-1616 does not include an SCI and therefore requires control data from a master
frame.
The DVS-1616 has a BNC labeled “COMM” which is used to connect a coaxial cable to a remote control panel.
Multiple control panels are attached via BNC ‘T’ connectors at each panel to perform a looping network. Total cable
distance can be up to 2000 feet. The system can support as many as sixteen control panels.
The DVS-1616 includes the SCI-1616 which provides a 9 pin D connector for external control of RS-232/RS-422
protocol. This system uses the SCI-1616 module which operates from SCI-2144 protocol which is standard for the
2100 Series. The SCI is located on the rear far left side of the frame.
The DVM-1616 does not include an SCI-1616 module or control panel and therefore is dependent upon a
master frame for control. The control data from the master frame is provided by an optional SLV-2126. This is a single
slot module which mounts in the master frame. Along with the module is an interface cable with 9 pin D connectors.
The control data enters the DVM-1616 at the 9 pin D connector on the power supply module located on the right side
on the rear of the frame. There is no direct connection for control on the DVM-1616. All control communications must
be connected to the master frame. Note that the DVM-1616 requires a control scheme of 16 inputs to 16 outputs. If the
master frame is configured in a smaller matrix the SCI in the master frame will need to be reconfigured for 16x16. This
is achieved by the DIP switch selection on the SCI within the master frame. Refer to the protocol section of the
operation manual for the master frame.
