The VS1 Voice Synthesizer is a 300/1200 baud
modem voice synthesizer, that uses the Hayes
"AT" command set.
The CR10 that will be communicating with the
VS1 will require a special UVEPROM in order
for the system to operate.
The VS1 can be operated as a remote site
modem connected to a CR10 datalogger and
used to transmit, by voice, real-time data stored
in the datalogger to the end user. A touch-tone
phone must be used to access the voice
synthesis functions. The VS1 will not work with
the older pulse-style phones. A Hayes or
Hayes-compatible modem must be at the
computer site to use the VS1 as a standard
modem.
The voice synthesizer is powered and enabled
by the battery powered datalogger. When the
voice synthesizer is disabled, it will draw less
than 50µA from the datalogger 5VDC output.
The VS1 Voice Synthesizer Editor is used to
adapt user-created *.DLD files to work with the
datalogger and the voice synthesis functions in
the VS1.
The VS1 can also be used as an originate
modem at the datalogger site. This allows the
user to program the datalogger to call specific
phone numbers when certain preprogrammed
conditions are met. For more information, refer
to Section 8.4 in this manual and to the CR10
Operator's Manual regarding Instruction 97.
2. SPECIFICATIONS
2.1. VS1 VOICE SYNTHESIZER
Current Drain:
ON HOOK(Quiescent state)-approx. 50µA.
OFF HOOK(Voice transmitting)-approx. 110 mA.
OFF HOOK(Data transmitting)-approx. 75 mA.
Voltage Supply Requirements:
A single 5 VDC-regulated supply. This supply is
from the CR10.
Operational Temperature Range:
-25°C to +50°C
Humidity:
If the VS1 Voice Synthesizer is installed in a
remote site that is exposed to the elements, we
recommend using a NEMA Class 4 enclosure
with a desiccant pack to control humidity.
Comparable enclosures are the CSI model
number ENC 12/14 with desiccant pack part
number 4905.
Installation in a building at standard room
temperature and humidity should not present a
problem.
