•
Jumping the CW pins makes the R-LS-450 operate continuously. This means that there is no pulsing of
the light source. Other jumper blocks must be configured correctly for this setting to work properly.

controls the pulse rate per second of the R-LS-450,
depending on the A/D converter you are using to interface to the spectrometer (see the table below for
pulse rates).
•
Jumping the CS pins controls the pulse rate via the spectrometer’s Continuous Strobe Setting in
OOIBase32 software (see the Using JP3 on the S2000 section that follows for more information).

Jumper Block 3 (JP3)
JP3 consists of two sets of pins. The jumper position determines the source of power control (manual or remote)
for the R-LS-450. Jumping the Remote pins allows you to control the R-LS-450 through the software (if other
jumper blocks are configured correctly).
