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 48i Trace Level-Enhanced
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.
Streaming data is sent out the serial port or the Ethernet port on a user-
defined periodic basis. Streaming data over Ethernet is only generated when
a connection is made on TCP port 9881.

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
