Interfaces Overview

CAN
The CAN is inter- module communication interface. It is a 2- wire serial
bus system supporting high speed data communication and real- time
requirement.
LAN
The modules have either an interface slot for an LAN card (e.g. Agilent
G1369B/C LAN Interface) or they have an on- board LAN interface (e.g.
detectors G1315C/D DAD and G1365C/D MWD). This interface allows the
control of the module/system via a PC with the appropriate control
software. Some modules have neither on- board LAN nor an interface slot
for a LAN card (e.g. G1170A Valve Drive or G4227A Flex Cube). These are
hosted modules and require a Host module with firmware B.06.40 or later
or with additional G1369C LAN Card.
If an Agilent detector (DAD/MWD/FLD/VWD/RID) is in the system, the LAN should be
N O T E
connected to the DAD/MWD/FLD/VWD/RID (due to higher data load). If no Agilent
detector is part of the system, the LAN interface should be installed in the pump or
autosampler.
RS-232C (Serial)
The RS- 232C connector is used to control the module from a computer
through RS- 232C connection, using the appropriate software. This
connector can be configured with the configuration switch module at the
rear of the module. Refer to Communication Settings for RS- 232C.
There is no configuration possible on main boards with on-board LAN. These are
N O T E
pre-configured for
• 19200 baud,
• 8 data bit with no parity and
• one start bit and one stop bit are always used (not selectable).
The RS- 232C is designed as DCE (data communication equipment) with a
9- pin male SUB- D type connector. The pins are defined as:
