Operation
TM-6710/6710CL High-Speed Progressive Scanning CCD Camera
This selects a mode for external shutter speed control. Hexadecimal shutter number (3 digit) follows
“SX” command (e.g., “080” = 128H, shutter speed = 4.1msec). It moves the shutter discharge pulse
at every 1H (32 µsec.) period from 254 (no shutter) to 1H (max. speed).
Command G
Function: A/D pre-amp gain control.
The “GM” command controls the gains of the A channel and the B channel. The “GA” and “GB”
commands fine tune the gain of the A and B channels respectively, to achieve balance. The ratio is
about 5:1.
Examples:
“:”, “GM”, “D2”, CR
D2 = gain 210

Command V
Function: A/D reference voltage control. In the default gain setting there is no shutter. The A/D
reference voltage bottom is preset to 0.45V. The controllable range of the reference voltage (Vref1,
