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 MPRR 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.

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.

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 MPRR is operating out of boot ROM. In
this case, the MPRR automatically enters download mode and waits for a new pro-
gram to be loaded into the flash memory. Follow the instructions in

Tag/Message Buffer
In basic communication protocol, the MPRR does not provide tag memory storage
beyond the quantity required for uniqueness checking. This feature allows adequate
buffering of tag data under normal operating conditions. The MPRR cannot operate as
a stand-alone component. When the buffer fills, subsequent tag IDs will be lost.

In error correcting protocol (ECP), a buffer of up to three additional tag reads will be
held in case a host system is unable to acknowledge tag reads in real time.
