OPERATIONS
Page 98 MRC-565 Packet Data Radio Operations & Maintenance
To schedule data collection for our sensors and transmission of the GROUP SDATA report we
could enter the following commands:
SCHED,I,30:0,SDI,COLLECT,1,2
SCHED,I,30:0,OFFSET,15,EVENT,UPDT,1
The first command schedules data collection of sensor table items 1 and 2 every 30 minutes and
00 seconds. The second command schedules the event group 1 to be created and send every 30
seconds with an offset of 15 seconds to give time for the data collection to complete.
5.9.7 SDI, CMD, COMMAND TEXT
Transparent Mode command. This command will output the text to the SDI-12 data line exactly
as typed with the ‘!’ character appended to the end. The first character must be a sensor address
and the remaining characters should be some valid basic or extended SDI-12 Command. The ‘!’
character should not be entered.
Example: SDI,CMD,0V<cr>
A list of the basic SDI-12 commands is given at the end of this document. Some Sensor
Manufacturers have their own special commands for setup and calibration which this transparent
mode is designed to support. These commands are not saved in the radio configuration flash
memory so if the sensor does not retain it in a power cycle it will be lost. If this command is
entered as a real-time-scheduled command it will be saved in the configuration flash memory.
5.9.8 SDI, TRACE, {OFF/ON}
The SDI,TRACE command is useful for debugging the setup and operation of the radio with the
sensors.
The example below shows a data collection from a sensor testing device that was set up to
emulate a sensor. The trace output can get to be a lot of information and should not be left on for
long periods or its output can overrun the radio output memory and cause the radio to reset. Be
careful using this command option.
Characters enclosed in the “<>” characters are transmitted out of the radio. Characters enclosed
in the “[]” characters are received by the radio. The time tag is in hundredths of seconds.
Example with TRACE,ON
+sdi,collect,1
20:14:44.59 <BREAK>
20:14:44.60 <MARK>
20:14:44.62 <0M!>
