4.2.2

Outline of operational modes

There are four modes that can be configured for the Metron 2 to run in

– these change how the Metron 2

behaves between transmits and when it is connected to the GSM network. It is configured under the ‘system’
tab using the config tool or using the ,2, (system) command if configuring manually.

Mode

What it does

Power off between
transmit events (0)

The modem will power down between transmit intervals. During this time it will be
unable to receive any SMS messages, GPRS communications or connect to any
network.

Always on (GPRS
Pollable when idle) (1)

The modem will idle between transmit intervals and be pollable using GPRS.
Unit auto detects if internal battery is used and will default to 0 if this is the case to
optimise battery life. It will be able to receive both SMS messages and GPRS
communications and it will always be connected to a network.

Always on (SMS Pollable
when idle) (2)

Modem will idle between transmit intervals and be pollable using SMS only. No GPRS
capable SIM is required for this to work correctly.

Transmit on Power up
(then to SMS Pollable) (3)

Modem will idle between transmit intervals and be pollable using SMS only. No GPRS
capable SIM is required for this to work correctly. It will also initiate a transmit upon
power on. This may be useful as an indicator of when the unit loses power
