Computer
Displays A Bad
Tcom Message
* The computer may not be making full contact with the
dock. Try reseating the unit in the dock.
* The dock may not be properly connected to the host. Make
sure there is a connection. TCOM errors may happen when
telephone service is lost, or for reasons not related to the
physical connection.
Computer Takes A
Long Time To Boot
Up After A Reset
Normal time is between 30--45 seconds. If you do not have
your computer connected to a charging source the booting
should be less than 30 seconds. Short beeps about one
second apart occur during the booting process to indicate
that your
computer is working.
If it takes longer than that, contact Intermec support
personnel.
Tethered Laser
Data And Internal
Laser Engine Data
Does Not Show Up
In The Key Buffer
Load 64SCN7B with both “--e” and “--w” command lines
switches. Both are needed to enable power to the internal
engine and direct the data from both scanners to the
keyboard.

When Scanning
Data Using A
Tethered Scanner,
But Works Fine
With The
Integrated
Scanner
Check for non-displayable preamble, postamble, prefix, or
suffix characters being sent by the laser. The internal laser
engine sends a postamble of <cr-lf> by default. Either
disable them or code the application to handle them. The
integrated scanner and tethered lasers may be configured
by scanning setup bar codes.
Tethered Scan
Data Does Not
Show Up In The
Key Buffer But
The Integrated
Laser Data Does
Ensure that the tethered laser is configured for 9600, n, 8, 1
and the bar code data is prefixed with an STX (0x02) and
suffixed with an ETX (0x03).
