GPI / RS-422 B / LTC – GPI I/O and Metadata I/O

GPI, RS-422 and LTC signals are carried on different connector types on the various rear panels available for the
AMX-3981, to make most effective use of the available panel area.

 AMX-3981-75D-3SRP and AMX-3981-110-3SRP

For the two single width rears, all three signals are carried on an RJ-45
connector, with the pinout as shown in the table:

Note that in this configuration, only two GPIO are available, while the double-
width rear panels carry three

 AMX-3981-75-3DRP-F
