This is the ethernet to serial adapter - Tibbo branded. I was able to communicate with it using their Windows software.

This is the hardware. It loops through the same messages shown on the signs on the table in the bottom photograph.

If you can unplug the ethernet-RS232 adapter from the display I think I'd be inclined to test the ethernet-RS232 adapter by shorting pins 2 & 3 (is this a DB9 or a DB25 connector) to loop back any received characters, make a connection over ethernet and see if the adapter echos the characters typed. Also, directly connect a laptop to the serial input of the display (using an old laptop with a DB9 serial connector or a USB-serial adapter) and see if you can control the display using the commands given.

Once both of those tests are done reconnect the ethernet-RS232 adapter to the display. Remember to also consider baud rates, 8 bit or 7 bit, stop bits, and parity/no parity which could also cause it not to work until they are aligned.
