Camera power
The Prosilica GS 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 In/Out 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 allow communication from
the host system via the Ethernet interface to a peripheral device connected to
the camera. These signals are not isolated; therefore, careful attention should
be used when designing cabling in noisy environments.
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.
