Chapter 1 User’s Guide Scanning Made Easy The LS 3603 features Symbol Technologies’ patented “fuzzy logic” technology. This innovation provides artificial intelligence that compensates for poor quality bar codes and gives the LS 3603 the best first-time read rate anywhere.
Set Up Unpacking Remove the scanner from its packing and inspect it for damage. If the scanner was damaged in transit, call the Symbol Support Center at one of the telephone numbers listed on page 1-15. KEEP THE PACKING. It is the approved shipping container and should be used if you ever need to return your equipment for servicing.

Aim the scanner away from you and press the trigger. When you press the trigger, the scanning beam is energized for approximately 3.0 seconds (default). 3. Scan Make sure the symbol you want to scan is within the scanning range. See the LS 3603 Decode Zone diagram on page 1-11.
LS 3603 Product Reference Guide Aiming Scan the Entire Symbol Your scan beam must cross every bar and space on the symbol. • The larger the symbol, the farther away you should hold the scanner. • Hold the scanner closer for symbols with bars that are close together.
Place the LS 3603 in the stand, and it automatically turns on in a blinking, hands-free mode. Any symbol passed over the red scan line will be decoded. To conserve power, after a short period of time of non-use, the scanner will operate in a reduced power mode.
LS 3603 Product Reference Guide Battery Box Operation When using the LS 3603 with a battery box, you can use either an alkaline battery (recommended), or a nickel-cadmium rechargeable battery. Low battery power is signaled by four short, high tone beeps, coupled with scanning interruptions.

Chapter 2 Programming Overview Before programming, follow the instructions beginning on page 1-2 The LS 3603 is programmed by scanning appropriate bar codes. The bar codes are arranged in RS-232C, Wand and Synapse sections. Not all of the available parameters necessarily apply to your specific host systems. If, for example, the selected host is a wand emulator, and you enable Baud Rate, the parameter will be ignored until such time as a host recognizing that parameter is selected.
LS 3603 Product Reference Guide Scanning Sequence Examples In most cases you need only scan one bar code to set a specific parameter. For example, if you want to add Code 39 to the Wand parameters, simply scan the Add Code 39 bar code in the Wand Code Types section. The LS 3603 will issue a warble tone, signifying a successful parameter entry.

LS 3603 Product Reference Guide Parameter Descriptions • Set Parameter Defaults Scanning the SET ALL DEFAULTS bar code on page 3-3 returns all parameters to the values listed in the Default Table. (See page 2-29.) • Host Interface Code Scan the bar code corresponding to your host type. You must select a host type when you first set up the scanner and whenever you change host types.
This parameter adds five leading zeros to decoded EAN-8 symbols to make them compatible in format to EAN-13 symbols. Transmit “No Decode” Message This feature gives you the option to transmit “NR” when a symbol does not decode. Prefixes and suffixes enabled will be appended around this message.
Code 39 Check Digit When enabled, this parameter checks the integrity of a Code 39 symbol to ensure it complies with the modulo 43 check digit algorithm. ITF-14/EAN-13 Conversion If your terminal supports EAN-13, this feature converts a 14 character I 2 of 5 code into EAN-13, and transmits to the host as EAN-13.
The leading space is not buffered. Decode of a valid Code 39 symbol with no leading space causes transmission in sequence of all buffered data in a first-in first-out format, plus transmission of the “triggering”...
Selection of this level will significantly impair the decoding aggressiveness of the scanner. Decode Redundancy for Codabar When enabled, a Codabar symbol must be decoded in both directions before being accepted as a successful decode.

LS 3603 Product Reference Guide •RS-232C Options Baud Rate Baud rate is the number of bits of data transmitted per second. The scanner's baud rate setting must match the data rate setting of the host device. If not, data will not reach the host device or may reach it in distorted form.

Programming RS-232C Options (Continued) Software Handshaking This parameter controls the data transmission process. It may be used instead of, but not in conjunction with, hardware handshaking. The scanner provides five software handshaking options, listed below. Refer to the flow chart on the following page. 1.
Page 42
LS 3603 Product Reference Guide RS-232C Options (Continued) Software Handshaking 5. XON/XOFF When enabled, the scanner assumes an XON for the first transmission, and transmits scanned data until an XOFF is received. Transmission continues when an XON character is received. This option is automatically disabled when the unit is in Low Power mode.
• Transmit AIM ID Character Enabling this parameter, with the Transmit Code ID Character parameter enabled allows you to send the AIM code identifier in lieu of the Symbol identifiers listed above. The identifier will be sent as a three character prefix, in accordance with AIM specifications for symbology identifiers.
LS 3603 Product Reference Guide • Power Mode This parameter determines whether or not power remains on after a decode attempt. When in low power mode, the scanner powers down after each decode attempt. When in continuous power mode, power remains on after each decode attempt.
