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)
.
Example:
Y232
ppp
= 232(dec) = 11101000(bin)
new SCR value: 11101000

Control commands to write to or to read from the Sync
Control Register:
Y

set SCR
with

Return value: 0 = OK; 1 = not OK
I29<CR>
return sync control
Return value: SyC:
