GENERAL DESCRIPTION

Purpose of Equipment:

The model 935A Dual Tone Sender is a preprogrammed dual tone (Touch­Tone) encoder. It is intended to generate cue tone sequences to be
transmitted with satellite CATV audio to provide automated control of various
receiver and switching functions at CATV receiver sites.

Description of Equipment:

The Model 935A is supplied in a wall mount enclosure measuring
approximately 6 ½ inches long, 3 ¾ inches wide and 2 ½ inches deep. A wall
mount transformer / power supply is furnished with the 935A.

Four pushbutton switches are provided to select the proper code sequence
to be transmitted.

An eight-terminal barrier strip, accessible by removing the enclosure cover,
provides terminal connections for the power supply, audio output and remote
selection of tones.

Up to two four-digit “on-off” code sequences can be provided. The code
sequences may be altered by changing the plug-in memory in the Model
935A.
