Zebra Rapixo CoF has auxiliary signals in the following formats:
|
Total #of signals from each DB15 connector |
Total #of signals from cable brackets |
TTL auxiliary input or output signals | | |
Opto-isolated auxiliary input signals | | |
LVDS auxiliary input signals | | |
LVDS auxiliary output signals | | |
Total number of auxiliary signals | | |
When you route an external signal to an auxiliary signal or vice versa, verify that the external signal meets the electrical specifications of the auxiliary signal.
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 0 V (recommended) and 0.8 V for logic low.
You can set the direction of an auxiliary I/O signal using the Aurora Imaging Library-Lite function MdigControl() with M_AUX_SIGNAL_MODE.
You can set up the auxiliary signals in the DCF. Alternatively, for most commonly used functionalities, you can configure the auxiliary signals using the Aurora Imaging Library-Lite function MdigControl() (for example, with M_IO..., M_GRAB_TRIGGER..., M_TIMER..., or M_ROTARY_ENCODER...).
