●
Synchronizes the device clock with the NDAS-RT clock (only for devices connected to the
specialized NDAS port).
●
Provides access to the device's web interface
●
Creates an NJSP server to which other NDAS-RT program modules can connect locally or
remotely
Multiple devices can be connected at the same time. Each of such devices is provided as a separate
NJSP thread server.
For each hardware port on the NDAS-RT housing, the module matches a specific NJSP network port.
As a result:
●
The same device connected to different ports on the NDAS-RT housing will have a different
NJSP port number.
●
Different devices connected to the same port will have the same NJSP port number
●
If the device is not directly connected to the data logger but via a USB hub, the device is assigned
the NJSP port number out of the free numbers pool
12.1. Start of the Module
Open the
Modules
tab in the data logger’s main interface (see Fig. 4.1, 4.3). Find the line with
the NDAS One manager module, click the
run
button in this line.
If the information in the line has not been updated, click the
refresh state
button in the upper
right corner of the screen.
At the initial start the module may display an error message indicating the configuration file
was not found. This message will disappear after the required module configuration is set up
and saved.
12.2. Connection of devices
There are two ways to connect NDAS-One devices – via USB ports and specialized NDAS
ports.
Software for the NDAS-N data logger and the NDAS-RT multifunction module is identical,
but the data logger does not have specialized NDAS ports so the connection is possible only
through the single USB port. The functions and capabilities described in this chapter refer
both to NDAS-RT and NDAS-N, except for restrictions on the availability and number of
ports for connecting devices.
