I/O definition
Camera power
The Prosilica GB camera family has recently been updated to offer an expanded
input power voltage range. The camera serial number is used to differentiate
between cameras that offer 5 to 16 VDC and those that offer 5 to 25 VDC.
Isolated IO ground
The Isolated IO GND connection provides the user ground reference and return
path for In 1, and Out 1. It is recommended that the ground wiring be physically
close to the I/O wiring to prevent parasitic coupling. For example, a good cable
design connects In 1 to one conductor of a twisted pair, Isolated IO GND to the
second conductor of the same twisted pair.
RxD RS232 and TxD RS232
These signals are RS232 compatible. These signals are not optically isolated. Tie
RS232 ground to Camera GND to complete the RS232 circuit. Communication is at
11520 baud.
Input triggers
Input triggers allow the camera to be synchronized to an external event. The
camera can be programmed to trigger on the rising edge, falling edge, both edges,
or level of the signal. The camera can also be programmed to capture an image at
some programmable delay time after the trigger event.
