COM320 Voice Communications Modem

1. Introduction

The COM320 is a voice-synthesized modem that supports the CR800, CR850,

CR1000, and CR3000 dataloggers. The COM320 allows the datalogger to

announce over the telephone specific variable data, present state of flags and/or

control ports, and the ability to toggle flags and/or control ports. Dataloggers

can also be programmed to call specific phone numbers with different

messages when specific conditions are met.

Although the primary function of the COM320 is voice communications, the

modem is also capable of

data

communications. In data mode, the COM320

supports standard datalogger functions including program send, data collection,

and data callback.

This manual provides information regarding COM320 specifications,

installation, and operation. Section
