Dump circuit
The dump circuit, consisting of
DUMP
potentiometer, U2C, U13A and U13B, is not used in this
transmitter.
Remote interface PWB (NAPI83/01A)
See electrical schematics Figures SD-15 through SD-18.
The remote interface PWB performs the following functions:
•
Buffers all external remote control inputs and remote status/alarm outputs.
•
Provides buffered, analog sample voltages proportional to the B+ supply voltage, total dc
current, audio, forward power, and reflected power for external monitoring.
•
Conditions the audio (analog or DAB) input's gain and provides filtering and modulation
protection.
•
Provides monitoring samples of the transmitter's RF output (both analog and DAB). The
magnitude of the analog sample is automatically adjusted to ensure a relatively constant
voltage, nominally 1 V rms, regardless of RF output level.
•
Provides the connection for the system's external interlock circuit between TB1-1 and
TB1-2.
Remote inputs
RFI filtering is provided on all control input lines to ensure transmitter operation is not interrupted
due to RF pick up on control lines. Opto-couplers are provided to buffer/isolate the external circuits
and prevent any unwanted transients from affecting transmitter operation. The position of shorting
SINGLE/DIFF
jumper E19 allows the control inputs to be configured to operate from a single-ended
or differential input. Refer to
XR6/XR3 Installation Manual
for a detailed description on single-ended versus differential inputs.
