3. Connect a CAT5e/6/7 cable between the Master and Slave units. For devices controlled by up to 115,200 baud rate, this
cable can be up to 3935 feet in length (1200 meters). For devices controlled by higher baud rates (up to 921,600), this cable can
be up to 328 feet in length (100 meters).

Plug-in and Boot Up
1.
Power up the CPU and extended device. The red power LED on each extender should illuminate. Try sending
communication between the CPU and the serially-controlled device. The CPU and device should each react as if they were
directly connected to each other.
Note: The yellow (“Tx”) and green (“Rx”) LEDs on each RJ45 connector will flash anytime data traffic is passing between
the Master and Slave, indicating proper CATx cable connection and communication.
If insufficient power is provided by the connection to the CPU or the serial device, the red power LED will not illuminate. In this
case, an external power supply (9-30VDC) will need to be connected (sold separately- contact NTI).
