WARNING
ELECTRICALLY OPERATED PRODUCT
As with all electrical products, precautions should be observed during handling and use to prevent electrical shock.
NOTE
Make sure the plug is inserted all the way into the power connector or else damage to the power adapter may result. The
CSG-50 has internal protection circuitry to prevent it from being damaged should the wrong polarity of power be applied.
However, do not use an adapter of more than 9 volts at 500 milliamperes or damage to the CSG-50 may result.
3.2 Operating From Battery Power
You can operate your CSG-50 from battery power in order to use it in the field as a portable color bar or sync generator.
The CSG-50 can be operated from 9-to-12 volts DC, obtained either from a conventional 12 volt video camera battery or
other 9-12 volt DC source.
3.3 Connecting The Output Signals
Connect the CSG-50 to your video equipment as determined by the requirements of your system. In general, the CSG-50
"VIDEO OUT" signal is for equipment with composite video inputs labeled "VIDEO IN", REF VID", "GENLOCK", etc.
The CSG-50 "SYNC OUT" signal is for composite sync inputs labeled "EXTERNAL SYNC IN", "EXT SYNC", etc.
As with other video equipment, the CSG-50 VIDEO OUT and SYNC OUT signals need to be terminated by a single 75-
Ohm termination in order to provide proper video levels to your system.
3.4 Connecting the CSG-50 to Operate Multiple Pieces of Video Equipment
The are two methods of connecting the CSG-50 to multiple video inputs: by using "loop-through" or "T" connectors or by
using a video distribution amplifier.
3.5 Using a Distribution Amplifier
To use the CSG-50 with a distribution amplifier (DA) connect the desired CSG-50 output to the input of the DA.
Terminate the CSG-50 input to the DA. Use a video DA for the CSG-50 VIDEO OUT signal and a pulse DA for the
SYNC OUT signal. Connect the outputs from the DA to each of the components of your video system as required, making
sure each DA output is terminated only once.
3.6 Using Loop-Through or T Connectors
The single video (or sync) output of the CSG-50 can operate two or more video units without the need of a distribution
amplifier if the equipment can be connected to present only one 75-Ohm terminating load to the CSG-50 output.
Some video equipment has an internal termination which can be connected or disconnected by way of a switch, usually
labeled "TERM ON/OFF", "75-OHM/HI-Z", or equivalent. This is the most versatile. Other video equipment may have
no terminator and needs to be externally terminated. This is the next most versatile. The least versatile is equipment
having internal termination that is always connected and cannot be disconnected. This is the most common.
If your video equipment has two BNC video connectors for video "loop-through", connect the CSG-50 video output to one
of the connectors and switch the terminator off. Next, route the video signal from the looping BNC connector to the input
of the next piece of equipment. Repeat this process until all video equipment is connected. Then, on the last unit in
line, switch the termination on.
For equipment that does not have looping connectors, use "T" connectors at the input of each piece of video equipment
to provide the necessary video in/out connections.
When you have a single piece of equipment with a terminator that cannot be switched off, use it as the last piece of
equipment in the line, if possible. If you have multiple pieces of video equipment with terminators that can not be
switched off, you must use a distribution amplifier.
If none of your equipment has terminators, install a 75-Ohm BNC type external terminator at the loop-through output (or T
connector) of the last piece of equipment.
