My initial guess is some sort of data acquisition board. I've worked with old 8-bit PC ISA data acquisition boards and perhaps it is an RS232 version of something similar.
May help to post a pic of the other side of the board too.

hook it up to a serial port,
set a coms program to something standard like 9600 8n1
and power it up - it may start with a copywrite message or something.
do you have the tools to lift and dump the rom chip?
I figured it to be some type of serial board. I have a pace system I could lift the chip but I don't have anything to dump the chip. I was hoping it may be a rs432 board I could use it for a ptz camera. no leds. I will post a pic of the back side of the board
