Internet Protocol: Connect the RS-422 IN port on the relay unit to an RS-422 serial port on a networked device, such as a PelcoNet encoder. If the networked device does not have an RS-422 serial port, use an RS-232 to RS-422 adapter. (Refer to Figure 26 on page 28 for a sample illustration.)
2.(Optional daisy-chaining): If you are connecting multiple relay units in a daisy-chain series, use the data cables provided with the relay units to connect the first unit’s RJ-45 OUT port to the next unit’s RJ-45 IN port.
