Interval for switching to the main channel
With the “Interval for switching to the main channel” parameter, it is possible to set the interval over which the
device will attempt to initialize the connection to the repeater via the main IP channel. Which communication
channel is the main one depends on whether the Ethernet Adapter is connected to the device:
∙
if the Ethernet Adapter is connected to the device, the main communication channel is Ethernet;
∙
if the Ethernet Adapter is not connected to the device, the main communication channel is the GPRS channel
on SIM1.
For more details about the configuration of IP channels, as well as the rules for switching channels, see the description
of the
It shall be noted that it is possible to specify “Do not switch” as the value for the “Interval for switching to the
main channel” parameter. In this case, the forced switching to the main communication channel will be disabled.
This feature allows to use “equivalent” SIMs - if the device is connected via GPRS on SIM2, it will remain on this
channel until the channel is operational.
Test transfer interval
Use the “Test transfer interval” parameter to specify the interval with which the device will generate a test event
and transfer it over the currently available communication channel. It is important to understand that this interval
is always counted from the last event that was transmitted by the device. If there are no events for transfer at
the expiration of the interval, a test event will be generated and transferred. If this parameter is set to “Do not
transfer”, then the device will not generate test events (code
E602
).
Interval for event transfer control
Use the “Interval for event transfer control” parameter to specify the interval during which the audit system is
waiting for the event to be sent. The
audit system
is a program mechanism that controls the fact of the event
transfer to the receiver.
If the “Interval for event transfer control” parameter is set to any numerical value, the device will work as follows:
∙
If the audit system registers the absence of the event transfer within the time interval specified by the
parameter, then first the communication channel, which is currently used by the device, is switched;
∙
At the moment when the audit system has switched the communication channel, an event with the code
E754
is generated. The argument for the event with code E754 is the type of communication channel that stopped
the event transfer (1 – Ethernet or GSM, 3 – radio). The argument value is transferred to the field assigned
to the zone or user number.
∙
If the channel switching does not help, and events are still not transferred, then the audit system reboots the
device after the expiry of the event transfer control interval.
∙
After the reboot, two events will be generated. The code of the first event is
R305
, this event registers the
very fact of the device reboot. The second event code is
R754
, this event means that the reboot occurred by
the audit system command.
The default value for this parameter is 7 minutes. If necessary, the value can be increased. If “Do not monitor” is
specified for this parameter, the audit system will be disabled.
Interval for control of communication with wireless devices
“Interval for control of communication with wireless devices” is the interval within which at least one package shall
be received from a wireless device. If the wireless device does not send anything within this interval, a message
about the loss of communication will be generated. Wireless devices send test packages every 30 seconds.
If this parameter is set to “Do not monitor”, the device will not monitor test packages from wireless devices.
