Installation
Pre-installation:
Handling:
This equipment may contain or be connected to static sensitive devices and proper static free handling precautions
should be observed.
Where individual circuit cards are stored, they should be placed in antistatic bags. Proper antistatic procedures
should be followed when inserting or removing cards from these bags.
Power:
AC mains supply: Ensure that operating voltage of unit and local supply voltage match and that correct rating fuse
is installed for local supply.
DC supply:
Ensure that the correct polarity is observed and that DC supply voltage is maintained within the
operating range specified.
Earthing:
The earth path is dependent on the type of frame selected. In every case particular care should be taken to ensure that
the frame is connected to earth for safety reasons. See frame manual for details.
Signal earth:
For safety reasons a connection is made between signal earth and chassis earth. No attempt should be
made to break this connection.
Installation in frame or chassis:
See details in separate manual for selected frame type.
Digital Input and Outputs:
Input and outputs are all 75
Ω
BNC type for connection with high quality 75
Ω
coaxial cable suitable for either
1.485 Gb/s high definition digital signals for HD use, or for 270 Mb/s standard definition signals for SD use.
Ensure that links settings are correctly set for the mode of operation required as described in the
Configuration
section of this manual.
Alarm Output Connection:
A normally open, or normally closed, 2-pin connector is provided on the rear assembly for an alarm connection on
loss of signal input or loss of power. Pin 1 is permanently tied to ground. During an alarm condition an on board
relay contact either shorts or open circuits pin 2 to/from ground dependent on the position of link LK7, as described
in the
Configuration
section of this manual.
Front Panel Indicators:
Front panel LED’s indicate the presence of an input signal (SIG – Green); whether the input signal is an HD signal
(HD – Green) or an SD signal (SD – Yellow); and the presence of power to the module (DC – Green).
