Fiber optics
Link Systems
Fiber-optics link is used in Sega
machines such as Daytona, Sega Rally, Manx TT, Indy 500
etc. Each machine has a pair of connectors, one
transmitter (TX) and one receiver (RX) for the connection
of the fibreoptics cables. A rule must be observed at all
times that a cable plugged into the transmitter on the
one end must be plugged into the receiver of the other
machine on the other end. The connectors are marked
however, we can always distinguish the transmitter from
the receiver. A bright red light will shine from the
transmitter briefly when the machine is powered up.
The following diagrams show how to find the
machine, which fails to link by splitting the machines.
It is a very simple and an effective
procedure to narrow down which machine is causing the
problem. Remember that the defective machine may work
well in the "Single Mode" and it is worthwhile
to try. The machine can be temporarily operated in a
Single Mode before further action to rectify the link
problem is taken.

The picture above shows the
fiber-optics cables plugged into the transmitter and the
receiver of the Daytona Game Board.

Chain of four machines
using fiber-optics cables. One way to determine which out
of the four machines fails to link is to split this chain
into two sets of two machines.

The pair containing the
defective machine will fail to link.

Looping RX and TX
connector of the same machine (Sega Games) is useful
troubleshooting technique. If the game board and the fiber-optics link cable are okay the game will power up in
link mode (the machine must be set as a master).
