MPRX Reader
TransCore Proprietary 7–9
Append Information — Command Group 3
Group 3 commands append useful information to reader transmissions, such as IDs, error
messages, and sensor input reports. Auxiliary information such as reader number, antenna
number (or manual entry code), number of times the previous tag was read, and sensor
input status can be appended to the ID using the Group 3 commands.
30N Append Time and Date Selection
Command #30N selects the option of appending the time and date to transmitted IDs,
error messages, presence without tag reports, and input status change reports. The factory
default setting is time and date appended (command #302).
The reader returns an Error message if its tag buffer contains data. The reset reader
command #63 may be transmitted to clear the buffer; however, tag ID data will not be
reported. If this is unacceptable, allow the buffer to empty before reissuing append time
and date command
#30N . Append Time and Date commands are shown in Table 7 – 4 .
Table 7 – 4 Append Time and Date Commands
The reader transmits messages with time and date appended as follows. One space
separates the time from the date.
<string>&<HH:MM:SS.hh MM/DD/YY>
where
string
is a tag ID, error message, or report.
& separates <string> from the time and date.
HH:MM:SS is the time delimiter.
MM/DD/YY is the date delimiter.
Reader response:
Done
31N Append Auxiliary Information Selection
Command

selects the option of appending auxiliary information to transmitted IDs,
presence-without-tag reports, and input status change reports. Auxiliary information is
not appended to error messages. The factory-default setting is no auxiliary information
appended. The N variable specifies whether or not auxiliary information is to be appended.
Append Auxiliary Information commands are shown in
Table 7 – 5 .
