Specifications of the auxiliary and camera control signals
Matrox Radient eCL has auxiliary/camera control signals in the following formats:
When an auxiliary input signal is received in TTL format directly, it will be
clamped at a maximum of 5.7 V and at a minimum of -0.7 V to protect the input
buffer. Typically, the signal should have a maximum of 5 V and a minimum of
0 V. A signal over 2 V is considered high, while anything less than 0.8 V is
considered low.
The opto-isolated auxiliary input signals pass through an opto-coupler, a device
that protects the board from outside surges and different ground levels, and allows
the frame grabber to be totally isolated. The voltage difference across the positive
and negative components of the signal must be between 4.71 V and 9.165 V for
logic high, and between -5.0 V and 0.8V for logic low.
You can set the direction of a bidirectional auxiliary I/O signal using the MIL-Lite
function
MdigControl() with M_IO_MODE .
You specify the purpose of the camera control and auxiliary signals in the DCF
with Matrox Intellicam. You can then program these signals using the MIL-Lite
function MdigControl() with M_IO...
