These commands set the span concentrations to user-defined values to
value
, where
value
is a floating-point representation of the span
concentration in current selected units. The following example sets the
span concentration to 1000 ppb in the single range mode.

isc
iscreen
These commands retrieve the framebuffer data used for the display on the
i
Series instrument. It is 19200 bytes in size, 2-bits per pixel, 4 pixels per
byte arranged as 320 by 240 characters. The data is sent in RLE encoded
form to save time in transmission. It is sent as a type '5' binary C-Link
response with no checksum.
The RLE encoding consists of a 0 followed by an 8-bit count of
consecutive 0xFF bytes. The following 'c' code will expand the incoming
data.
