Section 3: Operation
“Multicast IP Address” field. In order for the change to take
effect, you must:
1. Enter the desired multicast address in the field
2. Click the “submit” button
3. Click the “Save” link at the top of the screen
4. Wait for the save to complete (typically 30 seconds)
5. Cycle power on the MPS.
Once this has been completed the MPS4264 will be config-
ured with the new multicast address.
For more information on the multicast function and
working with multiple MPS units at the same time, see
“Multiple Unit Operations” on page 22.
Web Server: “Terminal” Screen
The MPS4264’s web server integrates a “terminal”
emulator screen allowing the user to send simple text
commands to the scanner. While most of the configuration
variables in the module are accessible through the several
GUI web server screens, not every variable in the MPS can
be queried or changed through the graphical portions of
the web sever. For the remainder of the variables that are
not accessible, the “terminal” screen provides a simple
means to check and change every variable in the MPS.
LIST commands can be sent to check the current setting
of relevant variables and any command can be sent to the
MPS through the web server’s terminal.

The only limitation to the Terminal is that a SCAN cannot
be initiated through the Terminal. Because the SCAN
command cannot be sent, data cannot be displayed to the
terminal or collected using the terminal.
FTP Scan Data Transfer
The MPS4264 can transfer scan data via FTP to a FTP server.
The user may set up any suitable server or NAS capable of
running as a FTP server.
See the section on FTP settings to configure the MPS4264
for FTP transfer. The conditions of SSD and SST must be
satisfied before scanning will start.
When ENFTP is set to one, and a scan is started, the
software will attempt to open a file on the FTP server as
configured by all of the FTP settings. The time and date
that is indicated by the GetTime command is used in the
construction of the file name.
The file that is saved on the server is assembled as follows:
<path on server><base data filename><date>_<time>.<type>
Where <type> is .DAT - binary, .TXT - ASCII Text, .CSV - ASCII
CSV file.
The file is closed when the scan stops. If the file cannot
be opened on the server when the scan starts, the scan is
stopped before any data is output.
When collecting binary data to a FTP server with a scan rate
above 200Hz, the MPS will buffer 4 frames of data before
transmitting the data. In order to receive all frames in a
scan, FPS will need to be set to a value that is divisible by
4. You will not receive the last frames of a scan (maximum
total loss of 3 frames of data) if the total amount of frames
collected is not divisible by 4.
Example: if FPS is set to 102, and the scan rate is 500Hz,
you will receive frames 1 - 100, but you will not receive
frames 101 and 102.
The Binary TCP Server
The MPS4264 provides a binary TCP server designed to
support LabVIEW or any other computer based client. The
MPS expects a connection to arrive on port 503.
ONLY
ONE CONNECTION IS SUPPORTED FROM THE SERVER
due
to socket limitations in the MPS. Additional attempts to
connect to port 503 when an existing connection is present
will be refused.
To enable the binary server the SVRSEL must be set to 2.
When the SVRSEL is changed, the group must be saved with
a SAVE M command and the MPS rebooted.
