If TransCore releases a new version of the Encompass 4 Reader software or if the
Encompass 4 Reader seems not to be working properly, you may need to download
the software to the Encompass 4 Reader. Contact technical support or your TransCore
Encompass 4 Reader sales representative.
Startup
Upon startup, Encompass 4 Reader’s transmit a sign-on message or a boot ROM fail-
ure message.
Sign-On Message
If startup is successful, the sign-on message appears as follows:
Model E4 Series [software version] SNYYYYYY 
[Copyright notice]
where YYYYYY is the serial number assigned to the 4800 Reader unit being used.
Serial number 000000 is the default setting and is not a valid number. If this number
appears in the sign-on message, the serial number has never been stored into reader
memory. The serial number must be assigned by factory-authorized personnel using
command #695S...S Set Serial Number. Because only six digits are allowed in
the software, when setting the serial number skip the fourth (middle) digit of the
seven-digit number shown on the reader label.
If the flash memory checksum does not indicate verification, the sign-on message
appears as follows:
Model [E4] Ver 0.00x
[Copyright notice]
Boot Failure Message
The software performs a checksum function on itself. The function returns a specific
value for the particular version of software. If the value returned is not correct, the
boot ROM checksum assumes that locations have been corrupted and a failure condi
-
tion exists. If the boot ROM checksum is not correct, a boot failure message is trans-
mitted. If the failure message does not transmit, a communications error has occurred
or the boot failed to the extent that it cannot transmit the failure message.
If the failure message version number equals 0.00 and no serial number exists, the
flash memory checksum has failed, and the Encompass 4 Reader is operating out of
boot ROM. In this case, the Encompass 4 Reader automatically enters download mode
and waits for a new program to be loaded into the flash memory. Follow the instruc
-
tions in “Program Download” on page 5-5 to download a new program.
