Chapter 6. Further information about the Easy2
operation
In this chapter you will find the main important information about the
Easy 2
operation.
6.1 Primary and secondary communication channel
The
Easy 2
is capable of signalling the incoming events to two communication channels to
the remote dispatcher centre, via GPRS and by a GSM call.
The 2 channels can be enabled or disabled independently from each other. When all the two
channel is enabled, then the GPRS has priority and the voice call is activated only in case of
GPRS communication and transmission failure. If all the two channel is disabled, then the
signalling and life signal sending are inactive.
6.2 Using the secondary channel
Ther can be two server configured for transmitting the signals, but only for one server will be
transmitted the data. The other server will be used as backup. The order of the primary and
secondary server operation can be defined by the
SFUNCT
parameter. The device switches
from the primary to the secondary server when the primary server cannot transmit data. If
the secondary server will successfully receiving the data, then the data will be still sent for
more 5 seconds to this server. Every signal transmitting will reset the counter of this time
limit. When the timeout spent it will switch back to the primary server.
The sending is successful, when a handshake reply is received back from the server within 6
seconds after the device sent.
Transmitting options in case of defining multiply IP addresses:
Signalling to 2 IP addresses (e.g. Server1: remote dispatcher centre which replies ACK
response; Server2: server, no ACK response).
Use cases:
It will sending only for the primary server (
GPRSEN
enabled,
SERVER1
filled,
PORT1
filled)
It will sending to the secondary server (backup/spare) when the primary is not
available (
GPRSEN
enabled,
SERVER1
filled,
PORT1
filled,
SERVER2
filled,
PORT2
filled,
SFUNCT
value is
Server1, Server2
)
