Software Control of the K–2600 UV detector
In combination with this software, the K–2600 UV detector can measure
with up to four wavelengths simultaneously and perform an (almost)
unlimited number of scans over any desired wavelength range in every
run. Trouble free detection and instrument control is achieved by the
fully digitally operating KNAUER net.
This chapter will explain the basic knowledge needed for working with
the K–2600 UV detector under EuroChrom software control. For more
detailed informations concerning as well the features of the software as
running it, please consider the users´ handbook of the software.
Preparing for Software Control
Installing the KNAUER Net
The instruments of the „Maxi" series, i.e. the K–2600 UV detector and
the pumps K-1000 or K-1001, can be connected to the computer in
digital communication network, the KNAUER net, see chapter „RS 232
Serial Interfaces" on page 25.
The serial port of the computer is connected to one of the serial ports on
the first instrument, e.g. the photometer, with an Y-shaped cable
delivered with the software.
The second port of the photometer is connected to one serial port of the
next device, e.g. the pump. The ring is closed by connecting the
remaining port of the pump to the second plug of the Y-shaped cable.
