The LS 3603-I265A acknowledges and exe-
cutes RS-232 parameter configuration com-
mands, beeper control commands, and LED
control commands.
The scanner contains custom parameter de-
faults provided in the Parameter Definition Ta-
bles.
The new Continuous Laser On parameter puts
the scanner into a continuous scan mode.
When this parameter is enabled, the scanner
stays on as if it were in an Intellistand and re-
mains in a fast scan until the scan stand time-
out value expires. It then enters a slower
“blink” mode. The laser enters a fast scan
mode again at the next trigger pull.
Custom Features
The LS 3603-I265A allows an RS-232 host to
send parameter configuration commands,
beeper control commands, and LED control
command.
The host communicates with the scanner by
sending a Host Message. A Host Message is a
string that contains an STX, the total string
length, one or more Host Commands, an ETX,
and an LRC for the string.
RS-232 Host Mode
The scanner must be set for RS-232 (Standard)
Host Interface to accept configuration com-
mands and requests. RS-232 Host Interface is
the default interface.
Note that the scanner trigger must be pressed
after powerup before RS-232 communication
can be established with the host.
Host Message
When the LS 3603 is in RS-232 Host Mode, it
accepts Host Messages that contain Host
Command Strings. The format of the Host
Message is as follows:

<STX><L1><L2><L3>
<Host Command String>
<..more commands if applicable..><ETX><LRC>
Where:
STX = 02h
L1,L2,L3 = Three byte hexadecimal length
of data from STX - LRC. Each
byte of the hexadecimal length
is sent as an ASCII character.
For example, a length of 13
decimal = 00D hex, and
30h,30h,44h ASCII.
ETX = 03h
LRC = This check digit is the exclusive
OR (XOR) of all characters in
the string excluding the STX
character, but including the
ETX character.
The maximum length of the host message is
550 bytes.
Host Command String
Each Host Command String is of the format:
<L1><L2><L3><Host command>
<Param Group><Param ID1>
<Param ID2><Param Values>
Where:
L1,L2,L3 = Three byte hexadecimal length
of Host Command String, from
first byte of host command to
last byte of parameter value.
Host Command = Used to specify command.
Param Group = Used to identify parameter
group.
Param ID1 = Two byte hexadecimal value
Param ID2 transmitted as ASCII, used to
identify parameter offset within
the group.
Param Value = One byte hexadecimal number

Any other value for a host command causes an
error condition and a NAK string is transmit-
ted.
Note: The parameter commands only affect
the RS-232 host parameters; not the wand or
Synapse host parameters.
The LS 3603 accepts multiple single and group
parameter change commands within one host
message, and up to 25 host commands within
one host message. The scanner only accepts
one of the following host commands within a
host message: reset defaults, upload all param-
eters, and software ID request. The specific
host message for the single host commands
that don’t contain variable data are as follows:

Note: All n/a fields must contain a 00h value.
Multiple host commands are verified and exe-
cuted until an error occurs. Once an error oc-
curs a NAK STRING is sent to the host and
further commands are ignored. More specifi-
cally, if a host message is sent to the scanner
that includes three changes to a single parame-
ter host commands, and an error is found in
the second command:
• The first host command is verified and
executed - the single parameter is
changed
• The second command is found to con-
tain an error - NAK STRING is sent
• The third command is ignored.
ACK String
When the LS 3603 receives a host message it
responds to the host to let the host know if the
command was valid. If a configuration com-
mand was successful, the LS 3603 sends an
ACK STRING of the format:
<STX><L1><L2><L3><ACK>
<data><ETX><LRC>
Where:
<L1><L2><L3>= Three byte hexadecimal length of
the data string from STX - LRC.
ACK = 06h
data = If the user performed a download
command that did not require in-
formation to be sent to the host
(Change Params or Reset De-
faults) the data is a string of num-
bers that represent the command
values successfully implemented.
See Host Commands table for
command values.
If the user requested information
via an upload params or software
ID request, that information is
sent.

If the user downloaded a host message that
contained two host command strings, one to
change a single parameter and one to change a
group of parameters, the ACK String data
would be 01 (30h,31h) to represent the single
(command 0) and group (command 1) com-
mands. The ACK String would be:
<STX><009><ACK><01><ETX><LRC>.
The ASCII representation of this string is:
02h, 30h, 30h, 39h, 06h, 30h, 31h, 03h, LRC.
NAK String
If the download was not successful for any rea-
son (LRC incorrect or the data was invalid) an
error condition occurs and the LS 3603 re-
sponds with a NAK STRING of the format:
<STX><L1><L2><L3><NAK><reason><error
loc1><error loc2><error loc3><ETX><LRC>
Where:
<L1><L2><L3>= Three byte hexadecimal length of
the data string from STX - LRC.
The length is 11 decimal = 0B hex
= 30h,30h,42h.
NAK = 15h
Reason A (41h)= Invalid length, the ETX
was not found after the specified
length of a single download com-
mand (defaults, full param down-
load, upload requests), or not
enough data for specified length.
B (42h)= Invalid host command.
C (43h)= Invalid parameter
group.
D (44h)= Invalid parameter iden-
tification.
E (45h) = Invalid parameter val-
ue.
F (46h) = Invalid LRC.
G (47h) = Invalid STX.
H (48h) = Invalid multiple com-
mands (sent to host if single host
command is not send by itself).

(73-13583-265)
Revision B: June 2000

<error loc1> = The three byte error location
<error loc2> indicates which byte of the
<error loc3> download caused the error. When
determining the error location the
received STX is considered loca-
tion one.
For example, if a 14-character download mes-
sage was transmitted and the LRC was incor-
rect, the response would be:
<STX><011><NAK><F><014><ETX><LRC>
The lengths are translated to ASCII as follows:
011 decimal = 0B hex = 30h, 30h, 42h
014 decimal = 0E hex = 30h, 30h, 45h
The ASCII representation of this transmission
is:
02h, 30h, 30h, 42h, 15h, 46h, 30h, 30h, 45h,
03h, LRC.
The error location is more useful when multi-
ple parameters are downloaded; it then identi-
fies which param group, param ID, or
parameter value is invalid. When multiple pa-
rameters are downloaded any valid host com-
mands prior to the one that contained an error
is executed.

Param Group
This allows the user to specify which group is
being downloaded, or which group the single
parameter is in if a single parameter download
is being performed. Valid options are:
A valid param group is required for all com-
mands. An invalid parameter group causes an
error condition and a NAK String is transmit-
ted.
Each group contains related parameters. All
the groups are defined in the Parameter Defi-
nition Tables. These tables list the parameter
group, parameter ID, valid options, and the
standard default.

Param ID
This two byte field indicates what the parame-
ter offset is within its group. This field is veri-
fied for all commands. Use values of 00h and
00h when the Param ID is not applicable for
the command. The Param ID is a hexadecimal
number sent as an ASCII value. For example,
the offset 0A = 30h, 41h. Param IDs are speci-
fied in the Parameter Definition Tables.
If a parameter ID is invalid for the specified
group, an error condition occurs and a NAK
String is transmitted.
Param Value
This one byte field indicates what value the pa-
rameter should be set to. In general, 0 = disable
and 1 = enable. Each parameter has a one byte
value that should be converted to a hexadeci-
mal number before transmission. For example,
a length of 12 decimal = 0C hexadecimal. Valid
options and defaults for all parameters are
specified in the Parameter Definition Tabl es.
Most of the options and defaults in these tables
are decimal numbers (unless explicitly stated as
hex) and need to be converted to a hexadeci-
mal number before being placed in a Host
Command String. All reserved parameters
should use values of 00h when they are pro-
grammed via the Change All Parameters or the
Change A Group Of Parameters command.
An invalid parameter value causes an error
condition to occur and a NAK String is trans-
mitted.

Data Transmission Format
The length field is a hexadecimal value and
each number should be converted to ASCII.
For numeric values (0 - 9) this is done by add-
ing 30h. For values A - F, this is done by send-
ing the ASCII representation of the character
(A = 41h, B = 42h, etc.) For example, if the
length of a Host Message is 110, the hexadec-
imal length is 6Eh. This is transmitted as 30h,
36h, 45h.
The Parameter Group field of a Host Com-
mand String should be sent as ASCII data. The
valid groups 0 - 7 and 9 are transmitted as 30h
- 37h and 39h respectively.
The Parameter ID field of a Host Command
String is a hexadecimal number. This is a two
byte field and each number should be convert-
ed to ASCII. For numeric values (0 - 9) this is
done by adding 30H. For values A - F, this is
done by sending the ASCII representation of
the character (A = 41H, B = 42H, etc.) For ex-
ample, the Param ID 0D should be sent as
30H,44H.
The Param Value field of a Host Command
String contains decimal data (except for Host
Selection, Pause Between Beeps, and Length
Within Range). Before transmission each byte
value should be converted to a hexadecimal
number. For example, to set a length of 20, the
hexadecimal number 14 should be sent.
If new RS-232 communication parameters
(baud rate, stop bits, etc.) are sent, the param-
eters are activated when the ACK String is
transmitted. Once communication parameters
are changed the host must be changed to cor-
responding settings for successful communica-
tion.
Note: For RS-232 communication between the
host and the scanner to work properly, the
scanner must be operating in continuous pow-

on after a good decode.
See Sample Data Transmissions for examples
of:
• changing a single parameter
• changing two single parameters in one
host message
• changing a group of parameters
• changing a group of parameters and a
single parameter
• changing all parameters
• resetting defaults
• requesting a full parameter upload
• requesting a software identification.

sion is provided for each sample. For clarifica-
tion, some invalid sample messages and
responses are also given.
