7 AF, squelch, PTT
max. 8 channel remote control
(7 Bit + GND)
Sample Configurations Major 4a/5a
The following situation shows the easiest way for remote radio control using a Major 4a/5a. If a remote control
is not required, a 7-wire line is sufficient for AF, squelch and PTT.
If only a local 2-wire line is available the following set-up using a DC line interface FT630-2 is recom-
mended. In this configuration remote channel select and duplex mode are not possible.
