For diagnostic purposes, the
present state of external trigger
inputs (LINE SYNC A, LINE
SYNC B, FRAME SYNC) or the
internal line counter can be output
instead of pixel #1 and/or pixel #2
data.

The basic synchronization function makes use of the trigger input LINE SYNC A. The trigger mode is determined by
the settings in the "Camera Control" dialog, e.g. LineStart (1) or ExposureStart (4).
Advanced trigger functions are provided by combining LINE SYNC A with a second trigger input LINE SYNC B. The
operation mode is controlled by the entries in the
Sync Control Register (SCR)
.
Use control commands to write to or to read from the Sync
Control Register:
Y
ppp
<CR>
set sync control
with
ppp
= 0...255 (decimal)
Return value: 0 = OK; 1 = not OK
I29<CR>
return sync control
Return value: SyC:
yyyyy
(5-digits integer value as ASCII)
Example:
Y232
ppp
= 232(dec) = 11101000(bin)
new SCR value: 11101000
