<error loc1>
=
The three byte error location
<error loc2>
indicates which byte of the
<error loc3>
download caused the error. When
determining the error location the
received STX is considered loca-
tion one.
For example, if a 14-character download mes-
sage was transmitted and the LRC was incor-
rect, the response would be:
<STX><011><NAK><F><014><ETX><LRC>
The lengths are translated to ASCII as follows:
011 decimal = 0B hex = 30h, 30h, 42h
014 decimal = 0E hex = 30h, 30h, 45h
The ASCII representation of this transmission
is:
02h, 30h, 30h, 42h, 15h, 46h, 30h, 30h, 45h,
03h, LRC.
The error location is more useful when multi-
ple parameters are downloaded; it then identi-
fies which param group, param ID, or
parameter value is invalid. When multiple pa-
rameters are downloaded any valid host com-
mands prior to the one that contained an error
is executed.
