TX : When selecting the TX mode, the CCU modulates
the VBS signal input to the PROMPT VIDEO IN
connector on the CCU-TX7/TX7P, and modulated
signal is sent to the CA-TX7/TX7P.
RX : When selecting the RX mode, the CA modulates
the VBS signal input to the PROMPT VIDEO IN
connector on the CA-TX7/TX7P, and modulated
signal is sent to the CCU-TX7/TX7P.
Note : When using this switch, change as follows.
. In case of using the TX mode (TX side) ;
1) Disconnect CN8 and connect CN3 and CN7
on the CT-181 board.
2) Set S1 and S6 switches to "PROMPTER" side
on the YD-25 board of CA-TX7/TX7P.
. In case of using the RX mode (RX side) ;
1) Disconnect CN7 and connect CN3 and CN8
