4.1.13.2 The Communications Window (COM)
The Communication Window returns a summary of communication set-up details on user
command. Communication dialogue commands and responses, can be entered into the logger Call
and Clear fields to permit dialogue between the data logger and an external communication
device, for example, telephone modem, radio modem etc. This feature allows the data logger to
establish a call, pass the message, then clear the call via a variety of communication media. The
example below shows the communication dialogue for connection to a PSTN modem. The Call
Number fields permit entry of up to three host connection numbers for receipt of messages. In the
example below, a message would be automatically sent to both CN1 and CN2 destinations.
Message scheduling allows user programming of time scheduled message transmission,
SEND=09/5/1, instructs the logger to send a rainfall and river message at 09 hours from midnight
with a 5 minute offset, once per 24 hours. (ie transmit messages at 0905 daily, data collected at
0900).
