J3: Multi-Board Sync / Bi-directional General I/Os
There are 8 bi-directional General I/Os that can be interconnected between multiple boards. These
bi-directional I/Os can be read/written by Sapera application. Bi-directional General I/Os no.1 and
no.2 also can also act as the multi-board sync I/Os.
The multi-board sync feature permits interconnecting multiple Xtium2 boards to synchronize
acquisitions to one or two triggers or events. The trigger source origin can be either an external
signal or a software control signal. The board sending the trigger(s) is the
“Sync
Master
”
board,
while the one or more boards receiving the control signal(s)
are “Sync
Slaves
”
.
Setup of the boards is done either by setting parameters via a Sapera application or by using
CamExpert to configure two camera files (.ccf). For testing purposes, two instances of CamExpert
(one for each board) can be run on the system where the frame grabbers are installed.
Hardware Preparation
•
Interconnect two, three, or four Xtium2 boards via their J3 connector using the OR-YXCC-
BSYNC20 cable (for 2 boards) or the OR-YXCC-BSYNC40 cable (see
for 3 or 4 boards).
Warning
: Multi-Board Sync / Bi-directional General I/Os are only for use with Teledyne
DALSA frame grabbers within the same PC, otherwise electrical damage to boards can occur.
