program) to serial port 2 on the SX-550, you can configure an IP address using the internal command
console. To do this, set the terminal to 115.2Kbps, 8-bit characters, no parity, and no flow control.
Use the appropriate cable to connect the terminal to serial port 2 (if you are using the Evaluation
Daughtercard, the included serial cable will work for many devices). Press <Enter> and then enter
the following commands in response to the Local> prompt:
The SX-550 will restart, and you are then ready to configure it (skip the remainder of this section).

because this is a fairly complex process, we do not recommend it unless it is not possible to use a
wired connection.

You will see a reply from the SX-550 with the number of bytes and other
information if the address was successfully set.
If you get an error message or no response, then the IP address was not set. If
this is the case, the SX-550 may not be at its default configuration. To reset the
SX-550 to its default settings, hold down the test button on the Evaluation
Daughtercard for more than five seconds. If you are not using the evaluation
board, short GPIO7 on the OEM header to ground (4.7 K-ohm pull-up resistor
