TDIF Interface PCB
Both a TDIF input and a TDIF output card can be connected to one of the
two 25-pin D-type sockets on the TDIF Interface PCB 1.940.632. In this
way, the inputs and outputs of two 8-channel digital recorders (e.g. DA-88)
may be connected with one single cable each.
For the connection to the backplane, two 16-pin flat cables are used. Fur-
thermore, the TDIF Interface PCB connects to a BNC connector panel han-
dling the sync signals.
Note:
The TDIF interface is suitable for short distances only. Even with high-
quality cable, a length of 5 m must not be exceeded.
