Chapter 4 Operation
BAD_B2 The 3rd generation transponder has replied with an indication that both the
meter reading and serial number checksums have failed. This could be due
to a new battery being inserted in the transponder, or due to a malfunction.
The transponder should be checked and reprogrammed. The meter reading
should not be trusted.
N_T_RP The transponder has replied with a good reading and is showing a tamper
status, but during the tamper reset verification, the transponder reply
resulted in a NO_RD status. The reading for the transponder is good, but
the tamper condition may or may not still exist.
B_T_RP The transponder has replied with a good reading and is showing a tamper
status, but during the tamper reset verification, the transponder reply
resulted in a BAD_RD status. The reading for the transponder is good,
but the tamper condition may or may not still exist.
PENDNG The transponder has replied with a particular non-good status, and is now
in a transition between the prior status, and a new status.
