C-Link Protocol Commands

This appendix provides a description of the C-Link protocol commands
that can be used to remotely control a Model 146i 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 topics:

Each command sent to the instrument 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".
