Pixel Mode
Specifies which pixels are transmitted. While all pixels are acquired on every scan, this
parameter determines which pixels will be transmitted out the serial port.
Command Syntax:
P{DATA WORD}
Value:
Description
0 = all 2048 pixels
1 = every n
th
pixel with no averaging
2 = N/A
3 = pixel x through y every n pixels
4 = up to 10 selected pixels
between 0 and 2047 (denoted p1, p2,
… p10)
5 = up to 10 pixel ranges between 0 and
2047 (denoted r1start, r1end, r2start,
r2end, …r10start, r10end)

Since most applications only require a subset of the spectrum, this mode can greatly reduce
the amount of time required to transmit a spectrum while still providing all of the desired
data. This mode is helpful when interfacing to PLCs or other processing equipment.
Spectral Acquisition
Acquires spectra with the current set of operating parameters. When executed, this command
determines the amount of memory required. If sufficient memory does not exist, an ETX (ASCII
3) is immediately returned and no spectra are acquired. An STX (ASCII 2) is sent once the data
is acquired and stored. If the Data Storage Mode value is 0, then the data is transmitted
immediately.
