LaserSpeed 8000-3 Instruction Handbook
RS-232/RS-422 Communication
Part No. 93463 / Drawing No. 0921-01561 Page 125 of 221 Revision A (Sep 2007)
Method 2
1) Start HyperTerminal (or any other terminal program) and set to 19200,
7, N, 2 (or the baud rate you want to use later). HyperTerminal is
installed with Windows 2000/XP, and can be found in Start
MenuProgramsAccessoriesCommunications
2) Cycle the gauge power.
3) Hit the Enter key 3 times, or transmit three
Carriage Returns (hex 0x0d).
4) Use the "Z" command to verify gauge is
communicating.
5) Use the "J" command to set the RS-232
baud rate or the "@" command to set the
RS-422 baud rate.
6) Reconfigure HyperTerminal to the new
baud rate if different from that in step 1.
Communication Protocol
This section lists the commands used to configure the LS8000-3, and to read
measurement data. Throughout this section, <CR> is used to denote a
carriage return, and <LF> is used to indicate a linefeed.
Notation Description
<CR> Carriage Return character
ASCII Value: 13
<LF> Linefeed character
ASCII Value: 10
<N> Integer Value (variable length)
Indicates an integer value with length from 1 to 9 characters. When sending
a command to set a configuration setting, the transmitted value can contain
leading zeros, but they are not required. When reading a configuration
setting, the LS8000-3 will not transmit leading zeros in its response.
Example Notation: L<N><CR>
Example Command: L100000<CR>
<IP> IP Address
Example Notation: *IPADDR=<IP><CR>
Example Command: *IPADDR=192.168.10.246
