1: Setup
Unpacking the LS-475
► Procedure
1. Unpack your lamp assembly carefully. Although the blue LED lamp is rigidly mounted, dropping
this instrument can cause permanent damage.
2. Inspect the outside of the instrument and make sure that there is no damage. Do not use the
instrument if damage is present. Contact your dealer for repair or replacement information, if
necessary.
3. Use this instrument in a clean laboratory environment (see
Operating Environment).
Contents
Your LS-475 package should contain the following:
LS-475 Blue LED Pulsed Light Source
One IC-DB15-2 interface cable for shutter operation
Additionally, you will need an approved power supply for the LS-475, such as the Mikropack PS12V/1.25A power supply.
General Configuration
► Procedure
To set up your LS-475,
1. Plug the power supply into an outlet and into the back of the LS-475
2. Screw an optical fiber onto the SMA connector on the front of the light source.

LS-475 Specifications
This section provides information on the operating environment and physical components of the LS-475.
Operating Environment
The following table provides information on optimizing the operating environment of your LS-475.
Operating Environment The LS-475 Unit . . .
Moisture Is designed for operation in dry rooms only.
Ventilation Should be situated so that its location or position does not interfere
with proper ventilation.
Heat Should be situated away from any device that emits excessive heat.
Object and Liquid Entry Should be positioned so that objects do not fall on top of the unit.
Additionally, ensure that no liquids are spilled into the enclosure
through openings.
Power Sources Should be connected to an approved power supply, such as the
Mikropack 12 VDC 1250mA analog regulated power supply (PS12V/1.25A)
LS-475 Components
The following sections describe the components located on the front and rear of the LS-475 unit.

Operating Instructions
Overview
The following sections provide instructions on operating the LS-475 Blue LED Pulsed Light Source.
Using the Continuous Mode
Continuous Mode means that the light coming from the LS-475 is continuous (not pulsed).
► Procedure
To set the LS-475 for Continuous Mode operation,
1. Move the switch on the back of the LS-475 to the ON position.
2. Move the switch to the OFF position to turn the lamp off.
Using the Pulsed Mode
The pulsing of the LS-475 is controlled through the Ocean Optics S2000 Spectrometer.
► Procedure
To set up the LS-475 for Pulsed Mode operation,
1. Plug one end of the supplied IC-DB15-2 accessory connector cable into the back of the LS-475
and the other end into the S2000 Spectrometer.
2. Move the switch on the back of the LS-475 to the TTL position. This places the light source in
Pulsed Mode.

3: Operating Instructions
Enabling Pulse Mode on an S2000 Spectrometer
► Procedure
To enable Pulse Mode on the S2000 Spectrometer,
1. Remove your spectrometer from its housing. Do not tamper with the optical bench.
Note
If you have more than one channel in your system, you may have to disconnect the
channels from one another. The master spectrometer is always on the bottom of a
multiple channel system.
2. Locate jumper block 3 (JP3) in the center of the green circuit board. Jumper Block 3 consists of
10 pins labeled by rows (/16, /14, /12, /10 and 2). The configuration of these pins control the
pulse frequency on the A/D converter connected to the S2000. The default factory setting is /16.
3. Configure the jumpers in JP3 for the desired pulse frequency.
Table 1 illustrates the various configurations of JP3 pins and their associated pulses per second.
Table 1: JP3 Configuration and Pulse Frequency
S2000 JP 3 Post # DAQ 700
Frequency (Hz)
/16 98.0 488.0 976.0
/14 24.0 122.0 244.0
/12 6.1 30.0 60.0
/10 1.5 7.6 15.2
For example, if you have an ADC1000 A/D converter, you have four choices for pulse frequency
from the LS-475: 976, 244, 60 and 15. If you choose to configure 244 pulses per second, place a
jumper over the pins next to the
When using the pulsed flash mode, you must ensure that the number of flashes is constant for
every integration cycle. To achieve a constant number of flashes per integration cycle, the
integration time must be a multiple of that shown in Table 2. Integration times are set in the
OOIBase32 software. See the
Instructions
for more information.
