Specifications of the auxiliary signals
Matrox Radient eV-CXP has auxiliary 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 0.8 V for logic low.
You can set the direction of an auxiliary I/O signal using the MIL-Lite function
MdigControl() with M_AUX_SIGNAL_MODE .
You can designate each of the auxiliary signals in the DCF with Matrox Intellicam.
You can then program these signals using the MIL-Lite function
MdigControl()
with M_USER... , M_TRIGGER... , M_GRAB_EXPOSURE..., or
M_ROTARY_ENCODER...
