User Guide, Version 1.2

PS-mode

Receiver ON/OFF

1. When started, 7 messages are analyzed

and the average is calculated. The

ON/OFF interval (plus some margin) is

selected according to the shortest and

modem is switched OFF. Modem will be

switched on 60ms prior to next message.

2. The interval is measured all the time from

every message.

3. If the interval is shorter than 10ms from

average, additional 1ms is added to the

average value.

4. If the interval change is more than 100ms,

calculation starts from the beginning (from

point 1).

5. If the calculated “cap” for sleeping is less

than 100ms, no PS is used.

6. New calculation will also be done every

100 message intervals – this is for safety

reasons.

7. When the PS-time is used, it is so flexible

that the interval can change +/- 40ms,

without losing any messages.

3.3 Safe mode

When a fault has been detected by the Firmware, the module is set to Safe mode. In this mode

the module toggle’s the Stat Pin in 250ms interval indicating an Error and reboots the device

after 5s. When connecting to the device with SATEL Configuration Manager the Error code is

shown in pop up box. If the device does not recover after multiply reboots, please contact

SATEL.

3.4 Power up / power down scenarios

The modem can be set in five (5) states, “ON”, “OFF”, “sleep1”,” sleep2”, “PS-Mode”

When power is applied to the module, the module can be switched ON/OFF using the

ENA_MODEM pin to >1.2V.
