The RS232 serial interface is not an isolated RS232. External galvanic isolation may be added if

required.

Be sure to check whether your serial cable is a null modem cable, commonly known as

crossover cable, or a straight through cable. If in doubt, swap Rx and Tx, and RTS and CTS, at

the other end and give it another go.

Once connected, your serial device should be accessible on your Pepwave MAX router LAN IP

address at the specified TCP port.
