SM4M/SM16M Storage Module User Guide
3-2
Explanation: Option 22 selects binary printer output at 9600 baud. The left
digit specifies the device option and the right, the baud rate.
Refer to the datalogger manual for further details.
3.2.2 *4 Mode — Output Device Enable
The *4 Mode is used to enable the output of Final Storage data to a printer. The
Storage Module will capture this printer output.
Select option ‘X1’ in window 1, and set the baud rate to 9600 (option 02) in
window 2 (to match the Storage Module’s default setting). Data is written to the
Storage Module each time data is sent to Final Storage.
While the module will work with *4, data is stored in the
module in ASCII format which requires up to 5 times more
memory space than binary format. Consider buying an
operating system upgrade if you are using dataloggers that do
not allow binary data storage with Instruction P96.
3.2.3 *9 Mode — Keyboard-Initiated Data Transfer
The *9 Mode in the 21X and CR7 dataloggers is used to transfer a specified block
of data from Final Storage to the Storage Module. Consult the appropriate
datalogger manual for details. This function is different from the *9 Mode in the
CR10/10X/CR23X.
3.3 Special Data Storage Operations
3.3.1 DSP4 Heads Up Display
In addition to real-time monitoring of datalogger measurements, the DSP4 Heads
Up Display can be used with the CR10/10X, CR23X, 21X and CR7 dataloggers to
store and retrieve data and programs. With the DSP4 storage module function
enabled, datalogger Final Storage data can be sent to the Storage Module. Refer to
the DSP4 Instruction Manual for more details regarding use with Storage
modules.
3.3.2 Storing Burst Measurement Data from the 21X
Burst Measurement (Instruction 23) is a special datalogger instruction available
for the 21X and which makes fast analogue voltage measurements. Two options
are available for data retrieval with this instruction:
1.
Data is stored in datalogger Input Storage locations
or
2.
Raw data is sent out of the datalogger serial port.
In the second case, the Storage Module can capture data at 76,800 baud.
When the Burst Measurement (Instruction 23) is used with the 21X, select the
destination (parameter 4) option as 2 for serial port output at 76,800 baud to send
data to the Storage Module. 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 PC208W) will translate Burst data.
