Chapter 1

Setup

Overview

The MPM-2000 Fiber Optic Multiplexer is a compact instrument that can optically couple one input
channel to 16 different output channels. The MPM-2000 consists of a precisely controlled DC-motor with
encoder and end switch on a rotator block. The optical path couples via UV collimating lenses.

The Multiplexer features a CNC controller working in positioning mode, which eliminates step loss. The
MPM-2000 is software controlled and interfaces to a PC through the RS-232 protocol. It automatically
saves all calibrated positions in the memory of the controlling unit, and easy-to-use software facilitates
calibration. The software enables full control of the switching order and delay time.

The MPM-2000 is ideal for applications in process industry, where you need to measure multiple
locations with multiple probes but with a single spectrometer channel and/or light source. The MPM-2000
operates as a stand-alone unit and includes a sample program to guide you in setting up your application.
The CD contains a driver for Windows, and you can configure the MPM-2000 in Ocean Optics
OOIbase32 Platinum software.

The following sections provide instructions on unpacking and setting up your MPM-2000 Optical
Multiplexer.

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.

4. Submit the Registration Card to for warranty and support purposes.

Syntax

Every command sent via RS232 to the MPM-2000 consists of the following parts:

Command sequence, Parameter (if needed), Carriage Return [CR]

To set an absolute position you need to send:

LA1000[CR] // Load absolute position 1000
M[CR] // initiate motion

Command Description Example

M Initiate Motion (Move) M[CR]

LA Load absolute target position

Allows programming of the desired target position relative to the
present zero or "home" position.

POS Get actual position

This command returns the actual position

GST

Operating/Interfacing with the Optical Multiplexer

The software needs to execute the following steps:

1. Read the complete program out of the EEPROM in the multiplexer

2. Extract the Serial number of the MPM-2000

3. Extract the position for each channel out of the file and save them for example in an array

4. Set the position for any of the channels

The program can be read with the GPROGSEQ command. It will look like the sample program. Only the
software version, the serial number and the positions will change with each device.

Check for an MPM-2000 by looking for the serial number as follows:

MPM-2000 1x16: 03918XXXX
MPM-2000 2x8: 05046XXXX

Where XXXX = a running serial number

The positions are stored in the file as follows:

CH01-500 Channel 1, absolute position –500
CH133000 Channel 13, absolute position 3000

Once the positions are extracted and stored you can set the position of the motor with the command
sequence:

LAPosition[CR]
M[CR]

000-10000-120-1209 21

A: RS232 ASCII Commands

To check if the MPM-2000 has reached the given position you can poll the actual position (POS[CR]) and
compare it with desired position.

Note: A difference of +/-1 between the desired position and the real position can occur. This is not a

functional error.

Calibrating the MPM-2000

To calibrate the MPM-2000 Optical Multiplexer, you must write the complete program file to the
EEPROM in the MPM-2000. This means that every line included in the original file must again be
written to and stored in the EEPROM.

Caution

Do NOT change anything other than the numbers representing the channel
positions! Any other change can lead to a system malfunction.

Commands to Save a File to the EEPROM

Command Description Example

PROGSEQ Defines the beginning of a Sequence program. All commands

given after PROGSEQ will be sent directly to the EEPROM until
the END command

(

Caution: Do NOT cut the supply power to the motor during

programming).

END Defines the end of the program. All commands given after the END

will be immediately carried out by the motor.

GPROGSEQ Gets program sequence

This function returns the complete program stored in the EEPROM

ENPROG Starts the program

This Program command can also be saved with the EEPSAV
command. The program will then run directly after turning on the
power to the motor.

DIPROG Deactivates the program DIPROG[CR]

LR Loads relative position

Loads new relative position
