Description
Master
Set
The set of three (3) inter-Reader channels that have the most tag reads (C = center Reader, L = left
Reader, R = right Reader). (present only if in interpolated lane assignment mode)
Zone
Sub-zone information (a – f). (Present only if in interpolated lane assignment mode)
Ch
Channel number. Indicates the assigned channel (1-8). Channel 1 corresponds to the leftmost RF
module in the RF rack.
St
Transaction status.
Pgm indicates successful transponder programming.
PU indicates transponder programming status is Unknown (tag left zone before verify could
complete).
PF indicates transponder was not programmed successfully.
Read indicates the Reader is in read only mode.
CrossR indicates an informational report (not a transaction).
Txn
Transaction number. Note that transaction numbers may appear to skip when using 2 or more
Readers with Ethernet connection between them.
Ag
Agency ID of transponder in capture zone.
Sn
Serial number of transponder in capture zone.
Ahs
Number of handshakes up to voting time.
THs
Total Handshakes for previous transaction assigned to this channel.
GUARD
Shown for a transaction assigned to a RF channel set to Guard. These transactions will show !LC
to indicate that no report for the LC is generated. Tag programming is disabled for Guard channels.
?LA
In a POST report, indicates that a lane assignment change was detected between the voting time
report and the post time report. May be an indication that voting time is not optimal.
?PS
In a POST report, indicates that a programming status change was detected between the voting
time report and the post time report.
>LC
>LC indicates transaction is to be reported to lane controller (connection present or not). Only
appears on the Active CTM
!LC
!LC indicates transaction is suppressed (e.g. GUARD lane or CrossR transactions or CTM is
Inactive).
Cx-HS
HS tag handshakes seen up to voting/post time on the MasterSet center Reader.
Lx-HS
HS tag handshakes seen up to voting/post time on the MasterSet left Reader.
Rx-HS
HS tag handshakes seen up to voting/post time on the MasterSet right Reader.
Transaction Buffering
Transactions from OBUs, are processed by the CTM. When a Reader CTM loses communications
with an Lane Controller (LC), the Reader buffers OBU transactions and error messages (up to a
combined total of 400,000) in non-volatile memory (i.e. buffered messages will not be lost during power
