Tascam IF-TAD Owner's Manual page 11

Note that you should always use genuine TASCAM
cables, or cables which have been approved for use
with TDIF-1 interfaces by TASCAM.
Although these cables appear similar to certain types
of computer cables and use similar connectors, the
cables themselves are very different, and the different
electrical characteristics of the cables can cause dam-
age to the equipment connected with the wrong
cables.
If the use of cables other than TASCAM cables causes
or results in damage, the warranty is voided.

TDIF-1 indicator
This indicator lights orange when a valid DTRS signal is received
at the TDIF-1 connector.
If this indicator is not lit, it means that the unit has become discon-
nected, or is not switched on.
If the indicator is flashing, it means that both units (the TDIF-1
and the adat device) have been selected as the clock master, or
both have been selected as the clock slave. Make sure that one unit
is selected as the word clock master, and the other as the word
clock slave.

adat IN and OUT connectors
Use these connectors to make the appropriate connections
(IF-TAD IN to the adat device's optical OUT and the IF-TAD
OUT to the adat device's optical IN). Use only optical audio
cables as recommended by the manufacturer of the adat device.
