Synchronization and control signals
The following tables summarize the synchronization, timing, and control signals
supported by Matrox Helios eD/XD. Most of these signals are available by defining
auxiliary (general purpose) signals as such in the DCF. When an acquisition path
supports several signals of a specific type, the tables identify the one to which an
auxiliary signal can be defined. For example, for acquisition path 0, you can define
P0_LVDS/TTL_AUX_OUT2 as exposure output 0 and
P0_LVDS/TTL_AUX_OUT3 as exposure output 1.
Note that only the auxiliary signals of the first acquisition path used by a video
source are available (for example, if grabbing 10-bit RGB, only the auxiliary signals
for path 0 are available).
You can set each LVDS/TTL signal individually to either LVDS or TTL format
when accessed from the external auxiliary I/O connector 0 (DB-44) of the cable
adapter board.
