Input/Output Signals
Refer to your installed VisionPro documentation for details on how to connect an
encoder and hardware triggers to the DSMax frame grabber.
The DSMax frame grabber supports the I/O signals as shown in the following figure.
The frame grabber supports a maximum input voltage of 24V.
Signal Description
Encoder PhA+ Floating input. Use this when you
need to use a single ended input.
Encoder PhA- Weak pull up to 2.5V.
Encoder PhB+ Floating input. Use this when you
need to use a single ended input.
Encoder PhB- Weak pull up to 2.5V.
Common GND Used as ground for both encoder and
trigger I/O input.
Weak pull up to 2.5V.
Trigger- Weak pull up to 5V
Differential voltage of 1V needed. For example an single ended encoder
input into PhA+ needs a maximum voltage of 1.5V to signal ‘0’ and a
minimum voltage of 3.5V to signal ‘1’.
