Table 1: Command keys
Specific values can be adjusted either by using buttons or by sending numbers to the
eLockIn
. The device accepts numbers wherever the software expects user input. Just
like the other commands, numbers need to be passed to '/cgi-bin/remote.cgi', but have
to be enclosed by '_' (underscore).
http://192.168.1.7/cgi-bin/remote.cgi?8DD_100000_8
or
GET
192.168.1.7/cgi-bin/remote.cgi?8DD_100000_8
The command sequence shown above tells the
eLockIn
to
switch to 'LockIn' menu ('8')
enter 'Ref' submenu ('D')
adjust frequency ('D')
set frequency to 100 kHz ('_100000_') !! the second “_” is required even if there is
no further menu entry.
return to 'LockIn' main menu ('8')
