Aiming
Do not hold the scanner directly over the bar code. Laser light reflecting directly back into the scanner from the bar
code is known as specular reflection. This specular reflection can make decoding difficult.
You can tilt the scanner up to 55° forward or back and achieve a successful decode (Figure 2-3). Simple practice
quickly shows what tolerances to work within.

Chapter 4 User Preferences
Introduction
You can program the Symbol LS2208 scanner to perform various functions, or activate different features. This
chapter describes each user preference feature and provides programming bar codes for selecting these features
for the Symbol LS2208 scanner.
The Symbol LS2208 ships with the settings shown in the User Preferences Default Table on page 4-2 (also see
Appendix A, Standard Defaul t Parameters for all host device and miscellaneous scanner defaults). If the default
values suit requirements, programming is not necessary.
Set feature values by scanning single bar codes or short bar code sequences. The settings are stored in
non-volatile memory and are preserved even when the scanner is powered down.
If you are not using a Synapse or USB cable you must select a host type (see each host chapter for specific host
information). After the power-up beeps sound, select a host type. You only need to this once, upon the first
power-up when connecting to a new host.
To return all features to their default values, scan Set All Defaults on page 4-3. Throughout the programming bar
code menus, asterisks (
*) indicate default values.
* Indicates Default
Scanning Sequence Examples
In most cases, scanning one bar code sets the parameter value. For example, to set the beeper tone to high, scan
the High Frequency (beeper tone) bar code under Beeper Tone on page 4-4. The scanner issues a fast warble
beep and the LED turns green, signifying a succe ssf ul paramete r en tr y.
Other parameters, such as specifying Serial Response Time-Out or setting Data Transmission Formats, require
scanning several bar codes. See Laser On Time on page 4-7 and Scan Data Transmission Format on page 13-4
for descriptions of this procedure.

Chapter 5 Keyboard Wedge Interface
Introduction
This chapter covers Keyboard Wedge interface information for setting up the scanner. Use this interface type to
attach the scanner between the keyboard and host computer . The scanner translates the bar code data into
keystrokes. The host computer accepts the keystrokes as if they originate from the keyboard.
This mode of operation allows adding bar code reading functionality to a system designed for manual keyboard
input. In this mode the keyboard keystrokes are simply passed through.
Throughout the programming bar code menus, aste risks (

Hardware Handshaking
The data interface consists of an RS-232 port designed to operate either with or without the ha rdware handshaking
lines, Request to Send (RTS), and Clear to Send (CTS).
Disable St andard R TS/CTS handsha king to transm it scan dat a as it be comes availabl e. Select Standard R TS/CTS
handshaking to transmit scan data according to the followin g se qu en ce :
•
The scanner reads the CTS line for activity. If CTS is asserted, the scanner waits up to Host Serial Response
Time-out for the host to negate the CTS line. If, after the Host Serial Response Time-out (default), the CTS
line is still asserted, the scanner sounds a transmit error, and discards any scanned data.
•
When the CTS line is negated, the scanner asserts the RTS line and waits up to Host Serial Response
Time-out for the host to assert CTS. Wh en the host asserts CTS, the scanner transmits dat a. If, after the Host
Serial Response Time-out (default), the CTS line is not asserted, the scanner sounds a transmit error, and
discards the data.
•
When data transmission completes, the scanne r negates RTS 10 msec after sending the last character.
•
The host should respond by negating CTS. The scanner checks for a negated CTS upon the next data
transmission.
During data transmission, the CTS line should be asserted. If CTS is deasserted for more than 50 ms between
characters, the transmission aborts, and the scanner sounds a transmission error and discards the data.
If this communications sequence fails, the scanner issues an error indication and discards the data. You must
rescan the data.
If hardware handshaking and software handshaking are both enabled, hardware handshaking takes precedence.
NOTE The DTR signal is jumpered to the active state.

RS-232 Interface6 - 15
RTS/CTS Option 1
If you select RTS/CTS Option 1, the scanner asserts RTS before transmitting and ignores the state of CTS. The
scanner de-asserts RTS when the transmission completes.
RTS/CTS Option 1
RTS/CTS Option 2
If you select Option 2, RTS is always high or low (user-programmed logic level). However, the scanner waits for
CTS to be asserted before transmitting data. If CTS is not asserted within Host Ser ial Response T i me-out (default),
the scanner issues an error indication and discards the data.
RTS/CTS Option 2
RTS/CTS Option 3
If you select Option 3, the scanner asserts RTS prior to any dat a tr ansmission, rega rdless o f the st ate of CTS. The
scanner waits up to Host Serial Response Time-out (default) for CTS to be asserted. If CTS is not asserted during
this time, the scanner issues an error indication and discards the data. The scanner de-asserts RTS when
transmission is complete.

Software Handshaking
This parameter offers control of the data transmission process in addition to, or instead of, the control that
hardware handshaking offers. There are five options.
If software handshaking and hardware handshaking are both enabled, hardware handshaking takes precedence.
None
Select this option to transmit data immediately. No response is expected from host.
ACK/NAK
If you select this option, after transmitting data, the sca nner expects either an ACK or NAK response from the host.
When a NAK is received, the scanner transmits the same data again and waits for either an ACK or NAK. After
three unsuccessful attempts to send dat a after r eceiving NAKs, the scanner issues an error indication and discards
the data.
*None
The scanner waits up to the programmable Host Serial Response Time-out to receive an ACK or NAK. If the
scanner does not get a response in this time, it issues an error indication and discards the data. There are no
retries when a time-out occurs.
ACK/NAK
ENQ
If you select this option, the scanner waits for an ENQ character from the host before transmitting data. If the
scanner does not receive an ENQ within the Host Serial Response Time-out, it issues an error indication and
discards the data. The host must transmit an ENQ character at least every Host Serial Response Time-out to
prevent transmission errors.
ENQ

ACK/NAK with ENQ
This combines the two previous options. For re-transmissions of data due to a NAK from the host, an additional
ENQ is not required.
ACK/NAK with ENQ
XON/XOFF
An XOFF character turns the scanner transmission off unt il the scanne r receives an XON character. There are two
situations for XON/XOFF:
•
The scanner receives an XOFF before it has dat a to send. When th e scann er has data to send, it waits up to
Host Serial Response Time-out for an XON character before transmission. If it does not receive an XON
within this time, it issues an error indication and discards the data.
•
The scanner receives an XOFF during a transmissi on. Data transmission then stops after sending the current
byte. When the scanner receives an XON character, it sends the rest of the data message. The scanner
waits up to 30 seconds for the XON.
