3.1.7 Interfacing to Frame Grabbers
12-pin connector or BNC.
3.1.8 Sync Output and Clock Output
TTL level internal sync and buffered pixel clock output (14.31818MHz) are available from the TM-200/
TM-300 camera. The signal is an emitter follower output requiring a termination resistor at the end of
the cable. The suggested value is from 75Ω to 330Ω.
3.2 Board Layout and Adjustment
3.2.1 Processor Board
Connect Processor Board to test jig and check all functions.
Voltage Setting
AGC Adjust VR1 (AGC) so that the pot. is 2.0V.
MGC Set VR3 (MGC) at mechanical center (2.5V at pot.). Then set ext. gain pot.
(rear panel) to 3.6V at pot.
AGC MAX. Adjust VR2 (AGC MAX) to 3.±0.1V at pot.
