Isolated IO GND
This connection provides the user ground reference and return path for the In 2,
Out 3, and Out 4. It is also recommended that the ground wiring be physically close
to the used In/Out to prevent parasitic coupling. For example, a good cable design
would connect the required signal on one conductor of a twisted pair and the
Isolated IO GND on 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. Tie RS232 ground to Camera GND to complete the RS232 circuit.
Isolated out power
The isolated out power connection provides power for isolated signals Out 3 and
Out 4. The voltage requirement is 5 to 24 V DC. The current requirement for this
supply is a function of the optical isolator collector current and the number of
outputs used in the system. Isolated Out Power wiring should be physically close to
Out 3 / Out 4 wiring to prevent parasitic coupling.
Input triggers
In 1 and In 2
In 1 and In 2 allow the camera to be synchronized to some external event. These
signals are optically isolated and require the signal common (Isolated IO GND). The
camera can be programmed to trigger on the rising or falling edge of these signals.
