RFC-1 Remote Facilities Controller
General
power requirements:
12 volts AC, 0.55 amps maximum
size:
6.0" wide x 7.0" deep x 1.75" high, maximum
connectors:
"LINE" (RJ11C)
"TELEPHONE" (RJ11C)
dial-up telephone line
dual purpose, programmable:
1. For use with local telephone set
2. For use as dedicated control port
"RELAY PANELS" (16 pin)
outward dialing method:
interface relay panels and 12 volt AC power
"pulse" dialing; 10 pulses/second or "imprecise"
(Note 1) DTMF dialing with software versions 5.07
and later
Telemetry
telemetry/status output:
synthesized voice
maximum number of channels:
64 telemetry/status
telemetry source:
positive or negative DC voltage
minimum voltage required for full scale:
1.0 volt
maximum offset voltage:
sources may offset up to 30 volts from ground
telemetry resolution:
one part in 1020 minimum, software dependent
telemetry accuracy:
0.5% of full scale
Control
control source: DTMF tones/clock calendar/telemetry conditions
maximum number of channels:
64 OFF/ON control
control duration: as long as DTMF tone is present or minimum
programmed "relay on" time, whichever is greater
Note 1: The RFC-1 does not contain a dedicated DTMF generator. "Imprecise" DTMF tones can
be generated by the RFC-1 using tones which are prerecorded in the speech synthesizer.
Because of a broad frequency tolerance, these tones are swept slightly in frequency and are sent
at a lower amplitude than normal DTMF tones. In the vast majority of uses, these tones are a
workable substitute for precise DTMF tones although success can not be guaranteed in all cases.
