Jumpers (Junction Box MBOS2AB1)

The polarity of PTT keying can be configured separately for every radio using jumpers JP1 to JP4 

(position "1" (as in the scheme below) = +batt; position "2" = GND).

Board Layout (Junction Box MBOS2AB1)

The connection cable MBOS2Kx for the control set (Major) is connected to socket ST1. The radios 

FuG1 to FuG4 can be connected via terminal strips ST3 to ST6.
