ACC's Digital Voice Recorder may interface to the RC-96
controller so that any of the remotely recordable "tracks" may be
addressed through the Message Editor. Control signals are
passed to the DVR through Control Output 1 (Serial Data, DVR
connector pin 4) as part of the serial data stream supplied at that
output in the expanded remote control output mode. Information
from the DVR is supplied to the RC-96 controller through the
External Device Busy logic input (pin 7, blue). Audio from the
DVR drives the Transmitter Audio Mixer input (pin I, black) and
may be level adjusted in the DVR. Receive audio should be
adjusted to 5 volts peak-to-peak and the Tone-Tone audio should
be adjusted to 1 volt peak-to-peak.
A 2.2K ohm pull-up resistor must be installed on the serial data
line at the DVR to 5 or 12 volts. See the Digital Voice Recorder
manual, page 2-6, for details. Additional operational instructions
for use of the Digital Voice Recorder with the RC-96 controller
are supplied with the DVR.
