Bartington Grad-13 Series Operation Manual page 19

This window allows you to specify:
The 'Name' of the connection, this appears in the drop down list when you attempt to connect to
a Grad-13 device.
The Node Address of the Grad-13 is set during manufacture and should be kept as 1 by default.
Whether the connection is a Serial Connection (i.e. USB to Serial) or an Ethernet connection.
Serial Settings
If connecting via serial connection, the correct COM Port should be selected (this is normally
the last one in the list). By default, only the Brainbox ports are listed (to which the Grad-13 is
connected), hence you may only see one COM port in the list.
The correct COM port can be identified by looking for the RS422/RS422 Serial Port (COM...) in
your PCs Device Manager under Ports (COM & LTP), see Figure 11 for an example.
Baud Rate: The default baud rate is 115200.
Note: The Baud Rate has to be programmed in the Grad 13, therefore in most cases the
default rate should be used. The exception to this is when the Baud rate has been changed
by Bartington Instruments in order to output the full 200Hz bandwidth.
Ethernet Settings
Input the 'IP Address' and the 'Port Number' on the IP Address. (This will be printed on the
multiplexing box)
After configuring the settings and ensuring the Grad-13 device is powered on and connected,
you may test your settings by clicking 'Test'. This will test the connection but will not leave the
connection open, and will disconnect from the Grad-13 upon completion. This test will display
either a success or failure message prompting you to check the configuration.
Clicking 'Save' will save the connection and the new name will then be listed in the Manage Grad
Connections window. The connection can then be selected in the drop down list shown in Figure
8.
