Controlling the LDP-QCW via RS-232
Introduction
The RS-232 interface allows communications over a serial text interface as well as using the
PicoLAS protocol. While the text interface is designed for communication with a terminal
program, the PicoLAS protocol is designed as a system interact protocol.
The switching between the two protocols occurs automatically as soon as the LDP-QCW
receives a certain sequence. The corresponding commands are:
PING
for the PicoLAS protocol
“
init
” followed by <Enter> for the text interface
The connection settings are:
Baud rate
115200
Data bits
8
Stop bits
1
Parity
even
