Rack Mounting the 1U Enclosure
The product must not be rack mounted using only the front rack mounting ears. When installing the product in
a rack one of the following methods must be used: -
•Place the unit on a suitably specified, and installed rack shelf and secure the product to the rack via the
front rack ears
•Alternatively fit the unit using additional rear rack mounts
A suitable mounting kit is available for purchase from Snell & Wilcox by quoting the order code:
FGACK RACK-MNT-KIT
Note: The rear mounting brackets must be attached using the two M3 threaded inserts on both sides of the
product; the maximum length of screw that can be used is M3 x 6mm. Ensure that the product is secured to
the rack in all four corners.

INPUT CONNECTIONS
Composite A and B
These are the 2 Composite video inputs to the
decoder module via BNC connectors. Nominal input
level is 1 V p-p terminated in 75 Ohms.
Separated Y C
A Y-C (S-VHS, Hi-8 etc.) input signal may be
connected to the unit via 2 BNC connectors.
Y input level is a nominal 1V p-p into 75 Ohms.
C input is nominal color burst level into 75 Ohms.
SDI A & B
These are the 2 SDI inputs to the unit via BNC
connectors.
Reference Inputs
525 and 625
When suitable signals are connected to these
inputs, the video output of the unit will be fully
synchronised to the relevant signal source when the
genlock function is selected. There are separate
inputs for 525 and 625 line standard signals. If no
signal is present the unit will automatically revert to
internal free-running operation.
BNC loop-through connectors are provided and the
signal may be black burst or composite video at
standard level.

COMMUNICATIONS CONNECTORS
Remote
This 9 pin `D' connector on the rear panel allows
the unit to be connected to the RollCall 485 network
communications system. This connector may also
be used as a RS422 port. For more information see
Section 5 Modes of Operation.
RollCall
This single BNC connector allows the unit to be
connected to the RollCall network communications
system.
GPI 1 and 2
These BNC connectors provide GPI input and
output control for the module.
Both GPI1 and GPI2 may be configured as inputs
that will allow memory locations to be recalled.

Matching the Front Panel to a Gateway Address
If the CVR250 is to be used on a RollCall network with other equipment, it may be necessary to change the
unit address to that of a vacant network slot in order to avoid confusion between units.
If an address is already in use by the network the RollCall receive and transmit LEDs will flash alternately at a
1-second rate. In this event, the following steps must be taken to set a new unit address:
1. Select an unused network address for the unit.
2. Set the address using the two switches on the gateway card, which is located behind the front panel.
Note that this address will only be read at unit power up.
Position 0 on the left-hand switch will disable the RollCall function on the unit.
Addresses 00 to 0F are pre-arranged.
All other positions on these switches may be used to set the unit address in hex.
3. Restart the front panel by holding down the Y Gain and Black Level buttons together.
4. Select Yes to the front panel question “Restart panel! Are you sure?”
5. Hold down the Y Gain button to enter the setup mode.
6. When the message “Setup mode” is displayed, release the Y Gain button.
7. Momentarily press the Y Gain button.
8. Select Auto-Connect.
9. Ensure that the top two lines read
Auto-Connec\\\\snellwilcox.local\\root\\Marketing\\Prodmgmt\\Data00
?
by selecting ▶if necessary.
10. On the third line, change the middle two numbers
0000 (DB) 02
to match the network address selected in step 2 above.
11. Restart the unit.
