GENERAL PRECAUTIONS

** ESD PREVENTION STEPS MUST BE USED DURING ANY MODIFICATIONS AND/OR

REPAIRS TO THIS UNIT! **

Product ESD Information

This product contains ESD sensitive components, or Electrostatic Discharge sensitiveelectronic parts. The Electrostatic discharge is defined as the transfer of charge betweenbodies at different electrical potentials.

Electrostatic discharge has the ability to modify the electrical characteristics of asemiconductor device, possibly degrading or even destroying it. Electrostatic dischargealsomay upset the normal operation of an electronic system, causing equipment malfunction or

failure.

Laser Safety Information

Use of controls or adjustments or performance of procedures other than those specifiedherein may result in hazardous radiation exposure. Under no circumstances should thecustomer attempt to service the scanner. Never attempt to look at the laser beam, even if thescanner appears to be nonfunctional. Doing so could result in hazardous radiation exposure.

The MS7600 Unit is rated as a CLASS I laser product, as defined by The U.S. Federal Laser

Product Performance Standard (FLPPS): Title 21 of the Code of Federal Regulations; Part1000; [Parts 1040.10 and 1040.11].

Laser Classes

CLASS I, II, and IIA lasers are defined as:

CLASS I: cannot emit laser radiation at known hazard levels (typically continuous (CW):0.4microwatts at visible wavelengths). Users of a Class I laser products are generallyexempt from radiation hazard controls during operation and maintenance (but notnecessarily during service).

CLASS II: low power visible lasers, which emit above Class I levels but emitting a radiantpower not above 1mW. The concept is that the human aversion reaction to bright light willprotect a person.

CLASS IIAis a special designation that is based upon a 1000 second exposure and appliesonly to lasers that are "not intended for viewing" such as a supermarket laser scanner.These laser are emitting light in the visible wavelengths (0.4 to 0.7 mm) with power notabove 1mW.

THEORY & OPERATION

BASIC OPERATION OF A LASER BARCODE SCANNER

Basic Data Decoding Sectional Summaries:

Photodiode (Detector) Summary Receives the optical signal reflected off the bar code. Converts into electrical signal (current) of about 100nanoamps.

Pre-Amplifier Sectional Summary Part of the Signal processor board, usually contained in a shielded area of the PCB with the

Photodiode. Converts the electrical current to a voltage signal. Voltage signal is amplified by a factor of 1000. Ambient light noise is filtered out. Resultant signal is routed to the motherboard to primary signal

processing circuitry.

Signal Processor Section Summary Converts analog waveform into a digital signal that can be used by the microprocessor.

Decoder Section Summary Decoding algorithm decodes digital signals into ASCII characters.

TROUBLESHOOTING

AUDIBLE & VISUAL FAILURE MODES

Audible Indicators

When the MS7600 scanner is in operation, it provides audible feedback. These sounds indicatethe status of the scanner. Eight settings are available for the tone of the beep (normal, 6alternate tones and no tone) plus three volume settings.

One BeepWhen the scanner first receives power, the amber LED will turn on, thered LED will flash and the scanner will beep once. (The red LED willremain on for the duration of the beep.) The scanner is now ready toscan.

When the scanner successfully reads a bar code, the red LED will flashand the scanner will beep once (if programmed to do so). If the scannerdoes not beep once and the red light does not flash, then the bar codehas not been successfully read.

Razzberry ToneThis is a failure indicator. Refer to failure modes page 24.

Three Beeps - During OperationWhen placing the scanner in program mode, the red LED will flash while

the scanner simultaneously beeps three times. The red and amber LEDswill continue to flash until the unit exits program mode. Upon exitingprogram mode, the scanner will beep three times and the red LED willstop flashing.

When configured, 3 beeps can also indicate a communications timeoutduring normal scanning mode.

When using one-code-programming, the scanner will beep three times(the current selected tone), followed by a short pause, a high tone and alow tone. This tells the user that the single configuration bar code hassuccessfully configured the scanner.

Three Beeps - On Power UpThis is a failure indicator. Refer to failure modes page 24.

Visual Indicators

There is a red LED and amber LED on thefront of the MS7600. When the scanner ison, the flashing or constant illumination of

the LEDs indicates the status of the currentscan and the scanner.

No Red or Amber LEDThe LEDs will not be illuminated if the scanner is notreceiving power from the host or transformer.

Steady AmberWhen the laser is active, the amber LED is illuminated.The amber LED will remain illuminated until the laser is

deactivated.

Steady Amber and Single Red FlashWhen the scanner successfully reads a bar code, the redLED will flash and the scanner will beep once. If the redLED does not flash or the scanner does not beep once,then the bar code has not been successfully read.

Steady Amber and Steady RedAfter a successful scan, the scanner transmits the data to

the host device. Some communication modes require thatthe host inform the scanner when data is ready to bereceived. If the host is not ready to accept the information,the scanners red LED will remain on until the data can betransmitted.

Flashing Amber then Flashing RedThis indicates the scanner is in program mode. A razzberrytone indicates that an invalid bar code has been scannedin this mode.-Or-

If the unit is in sleep mode, each LED will flash once every15 seconds.

Steady Red, Amber offThis indicates the scanner may be waiting forcommunication from the host.

RS-232 Demonstration Program

RS-232 Demonstration Program

If an RS-232 scanner is not communicating with your IBM compatible PC, key in the followingBASIC program to test that the communication port and scanner are working. This program isfor demonstration purposes only. It is only intended to prove that cabling is correct, the comport is working, and the scanner is working. If the bar code data displays on the screen whileusing this program, it only demonstrates that the hardware interface and scanner are working.At this point, investigate whether the application software and the scanner configurationmatch. If the application does not support RS-232 scanners, a software wedge program thatwill take RS-232 data and place it into a keyboard buffer may be needed. This program tellsthe PC to ignore RTS-CTS, Data Set Ready (DSR) and Data Carrier Detect (DCD) signals. Ifthe demonstration program works and yours still does not, jumper RTS to CTS and DataTerminal Reading (DTR) to DCD and DSR on the back of your PC.
