Trying to link 2 Race Drivin' units together.
Unit 1 says unit 2 not responding. (laymans terms as I don't remember the exact message)
Unit 2 says Link not implemented when trying to enable in "Operator Screens".
I've searched the forum for similar questions but only found questions on different name machines using parallel cables.
Does anyone have the pinouts for the DB25 serial connectors? There was mention about pins needing to be crossed from a standard serial cable, which I am trying to use, but not pin info or if it was serial or parallel.
One other question: There are 2 serial ports on the interface board, SerialA and SerialB.
Does unit 1 need to be connected to SerialA and unit 2 connected on SerialB or are these to connect more than 2 games?
Thanks for any help in advance.
