V-9927A
DIGITAL MULTI-TONE GENERATOR
INTRODUCTION
The V-9927A was designed with ease of
installation and flexibility in mind. Connections
are by screw terminals located on the edge of
the PCB. The various options and tones are set
using option blocks located inside the enclosure
on the PC Board.
The V-9927A is a microprocessor controlled
multi-tone generator capable of producing a
variety of tone signals for various applications. It
is functional and backward compatible with the
previous V-9927.
Note: Double check all wiring as
connections to the unit are different.
