Section 2. Storing Data from Current Dataloggers
2-4
This function is different from the *9 Mode in the CR500/510,
CR10/10X or CR23X.
2.3 Storing Burst Measurement Data from the
CR10/10X, CR23X or 21X
Burst Measurement (Instruction 23) is a special datalogger instruction used to
make fast analog voltage measurements. Two options are available for data
retrieval with this instruction:
1. Data is stored in the datalogger Input Storage Locations
or
2. Raw data is output from the datalogger serial port.
In option 2, the Storage Module can capture the data at 76,800 baud. Burst
data is output by the datalogger in a unique format which includes calibration
measurements at the beginning and end of the series of measurements. Split
(part of the PC208/PC208W software packages) will translate this Burst data.
2.3.1 Burst Data with CR10/10X, CR23X Dataloggers
Entering a ‘3’ for the third digit in parameter 4 of Instruction 23 selects the
Storage Module as the destination of the Burst data. All Storage Modules
connected should be set to Fill and Stop and have consecutive addresses. The
Burst data will be sent to the first available (lowest addressed) Storage Module,
followed by the next lowest addressed, and so on.
2.3.2 Burst Data with 21X Dataloggers
To send Burst Measurement (Instruction 23) data to the Storage Module from
the 21X, set the Destination option (parameter 4) to 2 for serial port output at
76,800 baud.
