Internet. Enable this option to include these signal strength records in reports (including a
column in multi-column reports).
Signal strength name
: Name of the signal strength channel as it appears in Filtered and
Multi-column reports.
Signal strength Format
: Signal strength can be reported either as a percentage (0% to
100%), or in power units (-113dBm to -51dBm).
SMS Recovery period

See 5.7.5 - SMS Recovery, below.
Mobile phone number

Record the SIM card’s phone number here, for your future
reference. NOTE: the phone number must be entered manually; it is NOT obtained
automatically from the SIM card.
5.7.2.2
Local Network (LAN)
This device will use its Ethernet LAN connection to connect to the Internet.
DNS servers
: DNS servers are used to resolve any hostnames. By default, the two servers are
set to Google's Public DNS servers 8.8.8.8 and 8.8.4.4 and will work for most applications.
Please consult your network administrator for assistance.
5.7.3
Secondary Network
The secondary network can be setup to provide an alternative method of sending reports, in case
the primary network method fails.
It would normally be used with an (optional) satellite modem, for use in remote locations to ensure
that logged data is sent, even if the mobile network fails. Please contact Halytech for more details.
However it may be useful in a LAN environment to be able to send reports via mobile modem if the
Ethernet connection is not available, in which case LAN would be selected as the primary network
and mobile modem selected as the secondary network.
The type of network connection is selectable from the
Method
setting, in the same way as for the
primary network.
If the secondary method is set to
None
, only the primary network will be used.
NOTE: the secondary network is only used to send reports. It is not used for sending emails,
automatic software updates etc.
5.7.4
Transmit Mode
When a secondary network has been selected, the way it is utilised is determined by the
Transmit
mode
setting:
Fail over
:
The report is initially sent via the primary network and then, if the report could not
be successfully sent, it is sent via the secondary network method.
Both
: The report is always sent by both network methods, regardless of whether the
primary method fails.
Note that “Both” mode is only applicable when one of the network methods is satellite.
When using both LAN and mobile modem, the only available transmit mode is “Fail over”.
