General Description

The R-173 enables control of from 4 to 12, Model 3185E DTMF decoder cards. It also
contains the Model 3137B, Unattended Answering Device card, and a Model 3567 Voice
Response card. The Model 3185E boards allow control of customer devices by means of a
dry contact closure through a relay on the Model 3185E board. The DTMF control signals
may be input to the cards via a two wire analog signal, such as a microwave link or an audio
subcarrier on a satellite feed. Or they may be input via a dial up telephone line, connected
through the Model 3137B UAD and the 3567 voice response/control card.

If the input is through the telephone line, a voice response/control card is installed. It
provides a voice message to the caller, and requires a DTMF code to access the control
cards.

The individual cards may be programmed in unique ways. Each card may be individually
set for a distinct actuation code. Please refer to the set up instructions for specific types to
determine the best use in your application.

Installation

The unit is designed to mount in a 19 inch rack, and requires 2 RU (3.5 inches) of vertical
space. Using the hardware provided, mount the unit in a rack, to minimize wiring lengths to
controlled devices.

Refering to the diagram on page 7, connect the POTS (two wire dialup telephone) line – if
used – and any audio and switched lines in accordance with the system design.
Connections are provided for NO, NC and COM for each card’s relay. Also, the SET and
RESET controls for each card are provided.

Provision is made to allow telephone audio to be selectably available and switched at each
3185E card’s output. Or a different audio source may be introduced for this feature. The
non-POTS audio may also be used for control of the switching function of the 3815E cards.

After wiring is complete, connect the power plug to an AC voltage source.

Model 3567 Voice Messaging card.

If desired, a message may be entered into the voice/control card – model 3567 – to be
played to the caller on the POTS line. Recording a message requires temporarily removing
the adjacent PC board, reaching in with a finger to the small push button switch on the card,
depressing it, and speaking towards the top of the voice/control card in a normal voice the
message desired. When recording the message, you have 20 seconds to record a
message. Please leave several seconds of quiet time at the end of the voice input, to allow
easier entry of the access code.

To select the access code for accessing the unit with through the telephone line and the
voice/control card, refer to the jumper selection guide for the model 3567 card in the
included manual. Various 3 digit codes are available.

Model 3137B Telephone Interface card.

The unit, when connected to a dial up telephone line, will answer the telephone on the
number of rings selected. The UAD card may be programmed from 1 to 9 rings. The UAD
card will hang up the line when the calling party hangs up, upon receiving a “wink” (current
interruption pulse) from the telephone CO (central office). If the CO does not provide a
“wink”, an optional dial tone detection card may be purchased to release the line when a
dial tone is detected.

Another option is to place a jumper to select a time out, enabling the UAD to release the line
upon a predetermined time. This option may be enabled in conjunction with the “wink”
provision. Please refer to the manual for the model 3137B UAD card for complete
information.

Model 3185E DTMF Decoder card.

The 3185E decoder cards may be programmed to present a 600 ohm or 10 K ohm
impedance to the audio source. For use in this unit, they must be programmed to a 10 K,
unbalanced audio input, to prevent excessive loading of the audio source. If the driving unit
requires a 600 ohm load, program only one of the units to present this load, and the rest to
10 K ohms. Selection of latching or other relay behavior, and the number of digits, is
described in the manual for the 3185E card.
