PROBLEM: Game stuck in "Network Checking"

SOLUTION: Ensure the cables are routed properly as shown in Fig 1 and that they are in good condition, i.e. not cut, bent or squished from being run over by game.

Make certain that 5V ON Game & I/O Bds where applicable is 5.10vdc.

 

If cables are routed properly and power is good, confirm that each car in the network is capable of communicating by doing the following:

1. Make each car a master.

2. Using one good Fiber Optic Cable, individually link each car to itself as shown in Fig.2.

3. If any car does not come out of "Network Checking" and go into Attreact Mode, you can now find out what in the car is the cause of this by swapping boards into a known good amchine until you find the problem component.

 

If all cars will communicate as masters, they should communicate provided Fiber Optics are routed as shown in your Owners Manual.

If you have further Communications troubles, contact SEGA Technical Service Dept. @ 650-632-7580
