To connect the digital optical network:
Locate the [DIGITAL IN] and [DIGITAL OUT] connectors.
Remove the connectors' plugs (if present) and store for later use.
Connect one end of the fiber optic cable into the [DIGITAL
OUT] jack of the first machine in the system.
Remove the clear, plastic tube covering each end of the cable (if
present). The cable is non-polarized, so either end can be inserted into
the optical output.
Connect the other end of the fiber optic cable to the [DIGITAL
IN] of the second machine in the system.
Tip: if the machines are on, the cable from the source machine will
show a red light at the end.
For each additional machine, connect one end of an additional
fiber optic cable to the second machine's [DIGITAL OUT] jack, and the
other end to the third machine's [DIGITAL IN] jack. Its [DIGITAL
OUT] jack then connects to the fourth machine's [DIGITAL IN] jack,
and so on.
Finally, connect one end of a fiber optic cable to the last
machine's [DIGITAL OUT] jack, and the other end to the first
machine's [DIGITAL IN] jack.
This last step creates a loop, and thus makes the digital bus accessible
to all machines that are connected to it.
When connecting more than two machines, always connect the optical
cables in the same order as the sync cables (1 to 2, 2 to 3, etc.), so that
the digital routing will work correctly.
