Introduction

The Bogen TMC-4 is a programmable universal media-source
controller capable of learning and reproducing the infrared
commands for consumer audio-visual products. It is designed
for operation with various telephone switches (requires use of
Bogen TAM-B access modules), or from the MultiCom 2000
System telephones. When used with the MultiCom 2000 sys­tems, the TMC-4 provides additional features such as: reserving
media source, quick reconnect code, menu driven access, and
current user identification.

Each TMC-4 panel has four media 'stations' and can simultane­ously control up to four different media-sources devices from
standard touch tone telephones.

The TMC-4 decodes the DTMF tones from the telephone key­pad. The controller then transmits an infrared control signal to
the media-source via a small transmitter, which is mounted
over the media-source infrared receiver. Any function that is
available the media-source's remote control can be learned up
to 30 commands. In addition, the unit permits manual control
directly from the keypad on the TMC-4

Installation

The TMC-4 is designed for rack mounting and requires 3-1/2"
of rack panel space. The equipment to be controlled should be
mounted in the same rack directly above or below the TMC-4.

Power requirements are 120 VAC, 60Hz, 0.1A.

When installing a MultiCom 2000 system, each station on the
TMC-4 is connected directly to the annunciator (A) and
ground (G) terminals of a station on the relay module. See fig­ure 1A below.

When used with other telephone systems, one Bogen Model
TAM-B Telephone Access Module is required for each media
station (Diodes CR27 and CR28 must be removed from the
TAM-B for proper DTMF communications.) Refer to Figure 1B
below. Follow the instructions included with the TAM-B for
proper connection to the telephone system. Connect output
terminals PT and PR on the TAM-B to the A and G terminals of
a station on the TMC-4. Connect the contact closure N.O.and
COM terminals on the on the TAM-B to the respective sta­tion's EXTERNAL INPUT and G terminals on the TMC-4.

To connect the TMC-4 to a media source, plug the IR trans­mitter into the INFRARED SIGNAL OUTPUT. The IR trans­mitter is then mounted over the infrared detector on the
media source device. Make sure the infrared detector window
is clean and free of any oils before removing the self-adhesive
backing and mounting the transmitter.

Note

The location of the media-source's infrared detector

varies between manufacturers.You can use the remote

control at close range to locate the detector.
