Problem fitting new mobo for dm500

[ezferret]

just got a new dm500 mobo and the serial port connector has 8 pins but my old mobo had 3 pins
Tried as many different combinations as poss but dreamup doesnt see box
(Box starts up OK with soem chinese software on it)
Anybody know how to connect the mobo to the serial port?
BTW the new mobo also has a switch terminal on it, and the old one doesnt

dont see how your old mobo would only have 3 pins. All dm500 boards come with serial ports.

Thanks for reply
The serial ports on the back of the boxes have 9 pins but they connect to a ribbon connector which fit onto the motherboard
Its the motherboard of my old 500 that has 3 pins and the new mobo has 8 pins

so all you need is a serial port with ribbon cable for 8 pin connecter?? If so I have one spare I think.
