The DB-9 RS-232 port on your instrument conforms to the DTE EIA-
232 standard and can reliably communicate over shielded cable up to 10
meters in length, depending on the baud rate you use.
Note Your instrument is only designed to support unidirectional com-
munication with an external device. At this time, there is no
protocol for bidirectional communication.
Note Firmware version 3.0 and up contains improved support for con-
nection to Laboratory Information Management Systems (LIMS).
See User Interface (SETUP), Appendix E, and Appendix H for
more information.
For a sample RS-232 Port Setup, please see the Supplemental RS-232
Information Appendix at the end of this user’s guide.
Instrument software update
Your instrument software contained in two flash EPROMs on the main
processor board may be updated via the RS-232 port. Such software
updates are made available as new features, and other improvements are
added during the life cycle of the instrument. For information on the
availability of software updates, contact Advanced Instruments (see
Chapter 5) or an authorized distributor. For directions on performing
the RS-232 serial port software upgrade, consult the documentation sup-
plied with the upgrade package.
