Description of the MCA527 Firmware Commands
Command name CMD_SET_THRESHOLD
Compatibility Identical to the MCA166 command.
Execution right Necessary
Description This command sets the threshold value (thr: 0 … 60 percent).
Format integer integer integer long integer
Parameter preamble command thr 0 end flag
Byte string (HEX) A5 5A 47 00 thr 00 00 00 00 00 B9 9B
Remarks See next command.
Command name CMD_SET_THRESHOLD_TENTHS
Compatibility New MCA527 command.
Execution right Necessary
Description This command sets the threshold value (thr: 0 … 600 * 0.1 percent).
Format integer integer integer long integer
Parameter preamble command thr 0 end flag
Byte string (HEX) A5 5A 0D 01 thr
l
thr
h
00 00 00 00 B9 9B
Remarks This command has been added for setting the threshold with higher resolution.
Command name CMD_SET_SHAPING_TIME
Compatibility Compatible to the MCA166 command.
Execution right Necessary
Description The command sets the shaping time (dtc).
dtc = 1 shaping time low
dtc = 3 shaping time high
The command is ignored and responds with an error value if a measurement is still running.
Format integer integer integer long integer
Parameter preamble command dtc 0 end flag
Byte string (HEX) A5 5A 52 00 dtc 00 00 00 00 00 B9 9B
Remarks The MCA527 provides more than two shaping times, but in order to keep compatibility with older
software, this command has been retained. The command allows furthermore to chose the shaping
time from a pair of shaping times. This pair can be set by CMD_SET_SHAPING_TIME_PAIR.
Command name CMD_SET_SHAPING_TIME_PAIR
Compatibility New MCA527 command.
Execution right Necessary
Description The command sets the shaping time pair.(lst = 1 … 254 * 0.1 µs, hst = 2 … 255 * 0.1 µs, lst<hst).
The highest allowed shaping time is returned by CMD_QUERY_STATE527, byte offset 121.
The command is ignored and responds with an error value if a measurement is still running.
Format integer integer integer integer integer integer
Parameter preamble command lst hst 0 end flag
Byte string (HEX) A5 5A 0C 01 lst 00 hst 00 00 00 B9 9B
Remarks See also previous command.
