MPRX
TransCore Proprietary 8–7
Figure 8 – 5 Sign-on Message
The sign-on message appears as follows at a baud rate of 38,400 bps:
Model [software version] SNSSSSSS [Copyright notice]
where
SSSSSS
is the serial number assigned to the MPRX skipping the fourth character
printed on the reader product label.
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 not been stored into reader
memory. Contact TransCore Technical Support at 505-856-8007.
If the flash memory checksum is not verifiable, the sign-on message appears as follows:
Model [E4 BOOT] Ver 0.00 A
[Copyright notice]
If the failure message version number equals
0.00 E
and no serial number exists, the
flash memory checksum has failed, and the MPRX is operating out of boot ROM. In this
case, the MPRX automatically enters download mode and waits for a new program to be
loaded into the flash memory. Follow the instructions in
“Program Download” on page
5–4 .
Communications can also be verified by using the command sequence in Table 8 – 2 .
