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