MobileView™ Tablet T750 Flash Update
(Cat. No. 2727-T7B30D1F)
The MobileView Tablet 750 includes the capability to automatically
update its operating system and application firmware by means of an
utility built into the device. MobileView firmware updates will be
provided in order to enhance program functionality as well as to
integrate program fixes.
The latest Flash update image files will be available
on the Allen-Bradley web site:
“Flash” firmware refers to the ability of the Tablet
chips to be updated “in a flash”—without physically
replacing any components such as ROM chips. The
flash firmware update is completed by using a
standard communications software program.

the highest baud rate supported is 115,200 bits per
second (BPS). Note that some vendors sell extra high
speed communications ports that support baud rates
up to 921,600 BPS. Expect roughly a 20 minute
transfer time for 115,200 baud; 10 to 12 minutes for
230,400 baud; and 5 to 7 minutes for 460,800 baud
(MobileView Tablet maximum rate).
You must select at least 115,200 Bits Per Second;
lower baud rates are not supported.

Perform the Flash Update
Before actually transferring the flash firmware image
file to the Tablet, you should make sure it is stored in
a location accessible to the host computer.
Once communications are successfully established between the Tablet
and the host PC running HyperTerminal, the HyperTerminal screen
will present a Command List as shown below.
Publication 2727-GR001A-EN-P - September 2001
If the Command List does not appear on the
HyperTerminal screen, you should first confirm the

HyperTerminal and then check the cable
connections between the Tablet and the host
computer. Next, close HyperTerminal and then
reopen it. If this does not resolve the problem, reset
the Tablet and make sure you press the
button-combinations as shown in Table A. If you still
cannot see the Command List after performing these
steps, contact Rockwell Automation for additional
