Make anynecessary program input adjustmentsand secure the exciter(s) using fourfront panel screws located in a bagattached to the exciter(s).NOTERoute exciter program cables through aferrite toroid, provided with the exciter’sancillary kit, to the rear of the exciter(s).(f) For external exciter mounting,consider the following:• Connect a coaxial cable between theexciter’s RF OUT N connector and J1(exciter A) or J2 (exciter B) of RFdrive splitter/changeover assemblyA16 (see Figure MD-3 of the V10 orV5 Repair Manual).• Connect each exciter’s RF mute(safety interlock) control to thetransmitter’s exciter interlock control,using a single-conductor, shieldedwire (user supplied). The exciterinterlock controls are available on theEXC A and EXC B terminals of TB2on the remote interface PWB (A44).• Nautel exciters require an opencontact for normal operation. Forexciter A (A14), connect the centre-conductor to TB2-2 and the ground toTB2-3. For exciter B (A15, if used),connect the centre-conductor toTB2-5 and the ground to TB2-6.• Install the other ends of the RF mutewires from step (b) in a 25-pin D-subplug (Nautel Part # JS31, located in theblank exciter kit) with the centre-conductor at pin 4 and the shield at pin25. Mate the plug with the ‘Control/Monitor’ receptacle on the exciter rearpanel. A connector shell (Nautel Part #JK16) is also available in the blankexciter kit.
