Connecting the R-LS-450 Rack-mount Version
with an S2000 Spectrometer
You can configure the lamp using a switch and three jumper blocks on the circuit board of the R-LS-450
and, if applicable, one jumper block on the S2000 Spectrometer. The following section details the variety
of configurations available with the R-LS-450. You need to determine the best mode of operation for your
setup and configure your system appropriately.
Note
If you are using a USB-based spectrometer, instructions specifically for the S2000
spectrometer will not apply.
S1 Switch
The S1 switch is a three-position switch on the R-LS-450. The switch can be moved into the following
positions:
 Continuous wave operation
 Off
 Pulsed operation
Jumper Block 1 (JP1)
JP1 consists of only one set of pins. If you configure other jumper blocks correctly, a jumper over JP1
allows you to turn the R-LS-450 on and off via the Strobe Enable/Disable function in your spectrometer
operating software. This feature is only available with a “J” or later version of the S2000 spectrometer
(USB-based spectrometers have a fixed pulse rate of 1 ms).
Note
To find out if you have a J-series or later S2000, look at the third character in your S2000
serial number.
Jumper Block 2 (JP2)
JP2 consists of nine sets of pins. You can configure the number of pulses per seconds by changing which
pins are jumpered in JP2. However, pulses per second are also dependent on the master frequency of the
A/D converter you are using.
