Set Oscilloscope to Start
Code:
http://192.168.1.7/cgi-bin/remote.cgi?49_0_
Function: stops the oscilloscope screen from data acquisition.
Description:
4 … enter Osci menu
9 … select Run entry inside the Misc menu
_ … tells that a parameter is following
1 … equals the 2
nd
entry in this menu which is “STOP”
_ finalizes the data transfer (never forget this final underscore)
How to set multiple parameters at once
After finishes one entry with “_”, one can simply add further entries from the current
menu situation, which means that it is not required always to return to the top-most
menu “LockIn” or “Spectra”.
For instance, when keycode “859_1_0_” was used to enable the entry Channel inside
[Lockin/Display], one can simply continue to enter values in the Scale entry (key code
“1”) by adding “1_124_”. The total key code:
http://192.168.1.7/cgi-bin/remote.cgi?859_0_1_124_
simultaneously makes sure that channel 1 is selected and its value is set to 1 V display
range. The only limit is the length of the complete string which is about 128 characters.
Example Code
http://192.168.1.7/cgi-bin/remote.cgi?
859_0_1_124_9_1_1_124_9_2_1_124_9_3_1_124_
Function: sets the display ranges of all 4 displayed channels to 1 V. The code shown
with dark yellow background (
9_
0_
1_124_
) simply repeats by changing the channel
number, only.
9_2_1_124_
, for example, sets the display range for channel 3.

CREENSHOTS
After receiving the 'S' command, the
eLockIn
will save its current display content as
a JPEG image in '/screen.jpg'. Then it can be retrieved by a web browser or a similar
program such as the Delphi example shipped with the
eLockIn
.

If you are interested in obtaining actual channel values, you can either use the HTML file
sent by /cgi-bin/refresh.cgi or the text file /lia.dat. To extract pure data from
refresh.cgi's answer, surrounding HTML tags have to be cut away. On the other hand,
lia.dat provides pure numbers and is faster.
