4 Operation
4.1 General
The primary function of the MesCom is to send a message when inputs change state. The
MesCom must know how to determine a change of state and where to send the message.
The MesCom can support 6 contacts to which it can send messages via SMS, GSM (data)
or GPRS, in various predefined formats. For more detail see section 5.
The MesCom is supplied in un-administered mode with no contacts pre-configured. In this
mode the MesCom will accept SMS commands from any phone number.
The default
password is the last 4 digits of the IMEI number
. To exit un-administered mode you must
add at least one contact with administrator level access, see section 4.4.
Contacts can be configured not to receive messages, for maintenance users or while on
holiday etc
…
GPRS/GSM contacts can be a
“send and forget” (eg uploading to web based data
concentration services see section 11) or connection based hosts - for more detail on
reporting, see section 12.
Points (inputs and outputs) can be configured to send messages to SMS contact,
GPRS/GSM contact or both.
Points can be configured to record their state at routine intervals and/or record every change
of state (section 7.4)
