Operating From Battery Power; Connecting The Output Signals; Selecting The Output Signals - HORITA BSG-50 User Manual

Make sure the plug is inserted all the way into the power connector or else damage to the power adapter may result. The
BSG-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 BSG-50 may result.

3.2 Operating From Battery Power

You can operate your BSG-50 from battery power in order to use it in the field as a portable sync generator.
The BSG-50 can be operated from 9-to-13.5 volts DC, obtained either from a conventional 12 volt video camera battery, or
from the HORITA BP-50 12 volt battery pack. The BP-50 consists of eight rechargeable AA sized batteries, battery
holder, power cable, heavy duty Cordura cloth case with nylon strap, and convenient wall-type overnight recharger.

3.3 Connecting The Output Signals

You will need to connect the BSG-50 to your video equipment as determined by the requirements of your system. In
general, blackburst is usually required by video equipment that processes color information in some manner, such as a
TBC, switcher, or effects generator. Their video reference inputs may be labeled "VIDEO IN", "REF VID" or
"GENLOCK".
The composite sync signal by itself is usually used by equipment that does not process color information, but needs to be
synchronized vertically and horizontally, an example being many models of 3/4" professional VCRs. Generally, apply the
composite sync (CS) signals from the BSG-50 to equipment that has reference inputs labeled "EXTERNAL SYNC IN", or
"EXT SYNC".

3.4 Selecting The Output Signals

The BSG-50 comes set up from the factory to output six blackburst signals. You can change the outputs to other signals
available on the BSG-50 circuit board as follows:
1. Remove power from the BSG-50.
2. The bottom of the BSG-50 is a cover which slides out towards the front. There are two screws which attach the front
panel of the BSG-50 to the case. Turn the BSG-50 upside down and remove the two screws from the BSG-50 front
panel. Remove the front panel and slide the bottom cover out the front of the unit. If you have a Rackmount or
Shortrack packaged BSG-50, remove the four screws from the top cover and remove the cover.
3. Each of the rear panel BNC outputs connects to a signal on the BSG-50 circuit board using small 2-pin connectors. As
shown in Figure 3-1, six blackburst signals are output on JP16, JP17, JP18, JP19, JP20, and JP21, the four sync
signals on JP8, JP9, JP10, and JP11, and the two subcarrier signals on JP5 and JP6.
To select a signal for output on a particular BNC connector, follow the black and white wires back from that BNC
connector to its 2-pin connector that plugs into the circuit board. Then simply unplug the 2-pin connector from its
present location and plug it into the desired location.
For example, to output a composite sync signal on BNC connector number "4", follow the wires back from BNC
connector "4" to the 2-pin connector on the circuit board. Unplug the 2-pin connector from its present location and
plug it into one of the remaining available composite sync signals on connectors JP12-JP15.
When changing outputs, make sure to get both pins of the 2-pin connector inserted. The connector should slide on
smoothly and snap securely in place. Make sure the connector is attached correctly or no signal will be output.
