Sega model 2B not networking
« on: July 08, 2019, 08:46:32 pm »

My first post here.

Ok, I have two Sega Indy 500 racing cabs, one that I built a few years ago, and one I converted from Sega Touring Car a few weeks ago.

When set up as `TWIN` and `MASTER/SLAVE`, both machines hang on `V2.00 - Checking Network`

So - Both machines have the identical ROM set, comms board.
And,  I have tried :
  • swapping master and slave.
  • a total of 3 comms boards.
  • old original sega optic cables
  • new optic fibre cables
  • swapping RX and TX over
  • `loopback` on both machines

What I have noticed, is that when - with no optic cables plugged in, the TX on both machines is lit upon power-up, but go off when the network tries to link.

Please help, as I SO want to get these machines linked for 2 player Indy 500, as its a bit sorry with the sign `Not 2 player` on them,as the sit side by side.
