[Amps] JRC AT info need

[Traian]

Hi all,

Just got a JRC automatic remote controlled antenna tuner,
model NFC-802G, (include CFG 801 and CBA 801), it work
in conjunction with JSS-800 or JSS-850 transmitter.

The AT have five optically isolated I/O lines (two in and three out)
and need interfacing it with another amp.
Anyone having available documentation, service manual or tech info
about these AT remote control connections?

Thanks,
73,
Traian
