APPENDIX C: EVENT PROGRAMMING
Page 194 MRC-565 Packet Data Radio Operations & Maintenance
EVENT,UPDT, group-number
Produce an immediate SDATA group report when the command is entered.
Parameter
Description
UPDT
Update sub-command; i.e., issue a group sensor data (SDATA) report.
group-
number
Group number to be reported in an SDATA report. Valid range: 1 through
16.
This command can be included in the MRC-565 schedule to produce reports on a periodic or
prescribed time of day. For example, "SCHED,I,10:0,EVENT,UPDT,3" will schedule the
group 3 sensor data report every 10 minutes.
SCALE, chan-name, slope {, offset}
Enter engineering units scale factor and offset for an analog channel. This adds the optional
offset parameter to the original MRC-565 SCALE command. Analog event detection is based on
scaled values, not raw counts. The scaled value is computed as:
scaled value = (analog channel raw count * slope) + offset
Parameter
Description
chan-name
Name of analog input channel to be scaled by the factors provided in this
command.
slope
Multiplier scaling factor. The analog input channel raw count is multiplied by
this value. Valid: any decimal floating point number that can be represented
in Motorola 68000 32-bit floating point format. However, there is a further
restriction on the value of slope. See below.
offset
Bias scaling factor. This value is added to the product of the channel raw
count and the multiplier scaling factor. Optional parameter. Assumes zero
offset when not given. Valid: any decimal floating point number that can be
represented in Motorola 68000 32-bit floating point format. However, there
is a further restriction on the value of slope. See below.
Slope and offset values must be chosen such that the resultant scaled value is in the range -
8192.0 through -0.001, 0.000 and +0.001 through +8191.0. Only four digits of the scaled value
are significant.
