Laser Mirror Scanner LMS-Q280i
6 Data Communication and Interfaces
When using the LMS-Q280i without Ethernet / TCPIP interface, 2 interfaces are
used:
•
a
serial RS232
(PC COM-Port) interface for configuration and control
•
a
parallel ECP
(PC LPT-Port) interface for fast scan data output
With the Ethernet / TCPIP interface, these 2 interfaces (2 cable connections)
can be replaced by one interface (one cable), using 2 ports: a
data port
(port
number 20001) and a
configuration port
(port number 20002).
All syntax rules and data format / structure descriptions of the following chapters
are identically used for communication via the TCPIP interface ports, where the
rules relevant for the serial interface are used for the configuration port and the
data structures for ECP parallel interface are used for the data port.
With Ethernet / TCPIP interface some specific commands for TCPIP
configuration ( e.g. IP-address) have to be previously set using the serial RS232
interface.
6.1 Programming Mode / Measurement Mode for Serial Interface
The instrument provides a programming mode to set and display measurement
and control parameters. To enter the programming mode (leaving the
measuring mode) send a ^P (Ctrl P, ASCII 10hex) to the instrument, to leave
the programming mode (re-entering the measuring mode) send a Q<Cr> (like
quit). <Cr> means Carriage return (ASCII 0Dhex).
Measurements and scans are carried out in the measurement mode. After
power up the instrument starts with measurement mode.
The communication parameters are pre-adjusted in factory to
19200 baud
1 start bit
8 data bits
no parity
1 stop bit
For achieving electromagnetic compatibility, use original RIEGL data
cable for communications only!
