Configuring the COM Port
In the Bits per second box, select 115200, 230400, or 460800.
TIP
IMPORTANT
The higher the baud rate, the faster the transfer of
the image file to the Tablet. For standard COM ports,
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.
2. Leave all other settings (Data Bits, Parity, Stop Bits, Flow
Control) at their defaults.
3. Click OK.

Perform the Flash Update
TIP
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.
TIP
Publication 2727-GR001A-EN-P - September 2001
If the Command List does not appear on the
HyperTerminal screen, you should first confirm the
baud settings and port configuration of
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
assistance.
