Appendix B
C-Link Protocol Commands
This appendix provides a description of the C-Link protocol commands
that can be used to remotely control a Model 42i Trace Level analyzer
using a host device such as a PC or a datalogger. C-Link protocol may be
used over RS-232, RS-485, or Ethernet. C-Link functions can be accessed
over Ethernet using TCP/IP port 9880. For details, see the following

Each command sent to the analyzer over the serial port must begin with the
American Standard Code for Information Interchange (ASCII) symbol or
byte value equivalent of the instrument's identification number plus 128.
For example, if the instrument ID is set to 25, then each command must
begin with the ACSII character code 153 decimal. The analyzer ignores any
command that does not begin with its instrument identification number. If
the instrument ID is set to 0, then this byte is not required. For more
information on changing Instrument ID, see Chapter 3, "Operation".
