4.7 Operating the 30/60 Second Timer
The thirty or sixty second timer is started whenever the CSG-50 TIMER switch is set to 30-SEC or 60-SEC respectively.
The timer causes the VIDEO OUT signal to change from the selected color bar pattern to black after the indicated time has
elapsed. The color bar pattern is again selected whenever the TIMER switch is set to the center OFF position.
It should be noted that the change from bars to black (or black to bars) is color framed and takes place during the vertical
interval for minimum disturbance to the video signal.
4.8 Using the Timer to Stripe Tapes With Color Bars, Black, and Time code
The CSG-50 timer allows you to conveniently pre-stripe video tapes with SMPTE time code and a video leader consisting
of color bars followed by black for the remainder of the tape.
For example, to use the CSG-50 with a HORITA TRG-50 SMPTE time code generator, connect them as shown in Figure-2.
Power up the CSG-50 and select the desired color bar pattern.

Use the 30/60/90/120 second automatic backtime feature of the TRG-50, to automatically backtime it 1 minute, leaving it
ready to start at "23:58:00:00".
When ready to start the recording, place the video recorder into record mode, set the CSG-50 TIMER to 30-SEC, then
momentarily switch the RDR/GEN/SET switch to GEN to start the TRG-50 time code generator running. Adjust recording
levels as desired.
After thirty seconds the video will change from color bars to black, then after another thirty seconds the time code will roll
through 00:00:00:00 time. 00:00:00:00 time is generally the "IN time" of the first edit on the tape if it is later used as an
edit master.
