Example CHUMP Commands
The following example is a Read Version command sent to a
reader. The f:0 parameter returns the full version string with
company, copyright, and date. The reply is shown in bold.
}Rv,f:0!
{Rv,d:”HFSARS_1.30[MB] Copyright (c) Samsys
Technologies Inc., s:000000000000”;3F
The next example is an ISO 15693 tag read for the value of the
user writeable block 0x0f (=15):
}:07,Rt,d:E0070000015CFCCA,a:0f, t:IS15;d0
{:07,Rt,d:E0070000015CFCCA,b:F0123456,
a:000F,t:IS15,f:0000;0D
The next example is a configuration read for the value of the
General Configuration Word (GCW):
}:07,Cr,d:GCW;e5
{:07,Cr,d:GCW,b:00000007;32
NOTE: CHUMP replies do not necessarily have all described
parameters, fixed parameter order, or fixed field widths. For
example: a:000F is the same as a:f
Any software application that parses CHUMP replies
should recognize punctuation and parameter names. The
application should not rely on data position. Some readers
may be configured to suppress tag type and flags to
conserve serial bandwidth.
