COM300 Voice Communication Modem

1. Introduction

The COM300 voice-synthesizer modem allows Campbell Scientific's voice capable dataloggers to transmit, by voice announcement, data stored in input locations and the current status of datalogger control ports and user flags. With voice communication enabled, a user can call a datalogger site and listen to announcements, or the datalogger can be programmed to initiate voice calls when alarm conditions are met. Though voice communication is the primary function of the COM300 modem, the device is also capable of standard modem communications.

This manual provides information specific to the COM300 hardware, including specifications, installation, and operation. Installation of the LoggerTalk Voice Communication Programming Software is covered, but use of the software is detailed in the software's on-line documentation.

2. Hardware and Software Requirements

2.1 COM300 Modem

The COM300 modem (Figure 1) is required at the datalogger site to activate voice communication. The modem is shipped with an SC12 cable (9-pin to 9- pin) to connect it to the datalogger's communication port. Surge protection at the datalogger site is required if it is not installed by the phone company. CSI offers a surge protector with or without environmental enclosure mounting hardware (model 6362 and 2372-01, respectively).

NOTE The modem’s communication port is configured to be compatible with Campbell Scientific’s CS I/O port. This is not a standard RS232 connection. Refer to Appendix A for the configuration of this connector.
