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 5–16 VDC and those that offer 5–25 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 RS-232 and TxD RS-232
These signals are RS-232 compatible. These signals allow communication from
the host system via the Ethernet port 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.
