R-LS-450 Rack-mount Blue LED Pulsed Light Sources
The R-LS-450 Blue LED Pulsed Light Source is the rack-
mount version of the LS-450. You can configure the R-LS-
450 to operate in continuous wave mode via manual
operation as well as through the software. You can also
configure the R-LS-450 to operate in pulsed mode through
manual operation and through the software.
Ocean Optics ships the R-LS-450 with following jumper
configuration:
•
Jumper over pins in JP1
•
Jumper over manual pins in JP3
•
Jumper over 2
10
pins in JP2 (fastest pulse rate
available)
To modify these jumper settings, consult the Operation
section that follows.
Operation
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.
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
Note: If you are using a USB-based spectrometer, instructions specifically for the S2000 spectrometer will not
apply.
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 feature in OOIBase32. 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 jumped in JP2. However, pulses per second are also dependent on the master frequency of the A/D converter
you are using.
The table on the following page contains information on the function of each set of pins in JP2.
