Download Considerations
You should consider the following factors when performing Program Download:
•
The MPRX does not process tags while in download mode.
•
The MPRX does not accept any program data unless a successful erase of flash memory has been
performed before transmitting the data. Erasing the flash memory typically takes two seconds.
•
Cycling reader power after exiting from download mode re-executes startup. If the new software
has been loaded without errors, the MPRX comes up in data mode. If a flash checksum error
is detected, the MPRX reenters download mode and transmits a sign-on message with a boot
version of 0.00x and without a serial number.
Note:
The MPRX uses default boot communications parameters when operating in download mode
–
38400 baud, 8 data bits, 1 stop bit, no parity, basic protocol
–
and does not echo commands.
Download Procedures
If TransCore releases a new version of the MPRX software or if the MPRX does not appear to be working
properly, you may need to download the software to the MPRX. Contact technical support or your
TransCore sales representative.
Startup
Upon startup, MPRX transmits a sign-on message or a boot ROM failure message.
Sign-On Message
If startup is successful, the sign-on message appears as follows:
Model E4 Series [software version] SNSSSSSS
[Copyright notice]
where
SSSSSS
is the serial number assigned to the MPRX 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 at a
baud rate fixed at 38,400 bps:
Model [E4] Ver 0.00x
