R-173 System Operation
Telephone access:
Dial the telephone number that the unit is connected to. When the unit answers, it will play
the message previously recorded to the caller. The caller enters the system 3 digit DTMF
access code. If the message stops playing, the code has been accepted. The user then
enters the codes required to actuate the selected 3185E decoder. Codes for any or all of
the 3185E decoders may be entered at this time. When the caller is done, he hangs up the
phone, and the unit waits for another call. If the jumper(s) are selected for reset, the 3185E
card(s) selected are reset to the off state at this time.
Audio Access:
If audio input is connected to the rear terminal, control of the 3185E cards may be initiated
from here. This audio input may also be the telephone line audio, if the proper jumpers are
selected.
