LS 1220 Product Reference Guide
For all commands that require a response, the response format is:
STX [x] <Data> ETX LRC
where:
STX =
02h
(Start of Transmission)
[x] =
character:
D
44h
Identify software
F
46h
Upload all parameters
<Data> = 30h + upper nibble of parameter 30h + lower nibble of parameter
ETX= 03h
LRC =
Exclusive-or of all characters transmitted except for the STX character.
The exception to the above rule, is the turn laser off command. To turn the laser off, the host
sends ESC
where:
ESC =
1bh (Escape Character)
Upon receiving a command from the host, the scanner sends the required information. If
the command requires no information in return, such as a laser on command, the scanner
sends an ACK to acknowledge receipt of the command.
For the identify software response, <Data> consists of an ASCII alphabetic string that
defines the version of installed software.
