Objectives
• To enable the students to write real test
programs in SVF and to execute online
• To provide a tool for test program validation
• To facilitate hands-on sessions with real
1149.X hardware

Setup: The MWS board
• The micro web server TAP controller
application uses a DSTINIm400 networked
microcontroller
evaluation board
(Maxim-Dallas)
• The current
prototype controls
one BS chain

Setup: IP and connections
• Use the MWS RS232C
connector and the MTK
tool to program a valid IP
address into the micro web server board
• Use FTP to load the server application into
the MWS board and
Telnet to launch the
server process

Set up (cont.)
• If the current IP of the MWS is known, a
quicker set up procedure is possible:
– Connect the card directly to a computer using a
regular LAN cable and telnet to its IP address
– Set up the new IP address (cuts the current
connection if in different subnets),
e.g. ipconfig -a 158.36.164.12 -m 255.255.254.0 -g 158.36.164.1
– Set the current IP of the computer to the same
subnet and reconnect (or use the LAN)
