3.3. INPUTS/IGNITION
3.2.3 Fix (Yellow)
As long as the Power LED is solid ON, this LED gives information
on the GPS receiver status. There are two possible states:
•
ON: The GPS unit is doing fixes. This indicates a well placed
GPS antenna with sky view.
• OFF: The GPS antenna is connected but the unit is not doing
fixes. This could happen even if the antenna is well placed, but
if this is the case, the situation should not be permanent. In
this situation the GPS messages transmitted by the unit may be
of lower GPS quality. Check the GPS antenna location and/or
type if the situation persists.
3.2.4 On line (Green)
As long as the Power LED is solid ON, this LED gives information
on the GPRS session state:
•
OFF: The unit is Not Registered on the GPRS network.
•
ON: The GPRS session is up and ready . When using TCP it
also indicates that all of the TCP connections with all of the
IP-type
Destinations are ready.
•
Blinking: The GPRS session is up and ready but at least one
of the TCP sockets associated with IP-type destinations is not
open.
When using UDP the LED is either ON or OFF.
When an APN is set the unit will always try to start and maintain
a GPRS session so the normal state of the On line LED when an
APN is set is either ON or Blinking.
Note:
