4.1.2.
Network settings
One of the most important features is the setting of the network, since in a structure multiple
recording units must be installed. To do this, it is necessary to enable the Master option in the
Master / Config/status section. The other instruments are Slaves. Communication in the network is
handled by the Master. In this way, it is possible to
perform common sampling, common trigger and
common alarm. All the details are given in Section 5.6. Please contact Syscom at
to have an application note dedicated to the preparation of a local network.
Figure 4.1.3. Subsection dedicated to the configuration of the network.
Here you define which MRs are part of the network. Simply
add
the IP-address of the MR. The
Master itself
must
be included (simply check the
itself
box). The IP address of the Master could be
shown as 127.0.0.1 (localhost) or as its own IP address (Figure 4.1.3).
The column
MRs status
should show ok after a few seconds: this means the Master is able to
communicate with the Slaves. The column
Time synced with master
should show
yes.
This
means the time difference in the corresponding MR is less than 3 seconds compared to the Master.
This is usually the case if all MRs have access to a NTP server in the Internet or if a specific MR in
the network is acting as time server. If you have an MR as internal time server, configure all other
MRs to use the IP address of this MR as NTP server (see chapter 5.3.2). Otherwise, in case of
GPS, you need to put the IP address of the MR3000SB which is connected to the GPS.
In the example proposed, three MRs are connected on the same local network, and the IP address
has been changed manually.
After that, you can define the conditions for a common trigger, named recording in all MRs in the
network. Each line contains a condition, the lines are logically OR combined. A condition might be a
single MR or a group of different MRs. If more than 1 MR is defined, the trigger condition in the
single MR must occur within 3 seconds.
Click on the
Add
button to set-up a new combination. Click in the
Edit combination
section the
select
box for the single MRs. In the column
Name
you may enter a mnemonic for this condition
(e.g. MR in cellar). In the column
Selected
the logical combination of this condition is shown. The
logical combination of all conditions is shown in the section
Logic function.
