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.
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.
The RS- 232C is designed as DCE (data communication equipment) with a
9- pin male SUB- D type connector. The pins are defined as:
If an Agilent detector (DAD/MWD/FLD/VWD/RID) is in the system, the LAN should be
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.
There is no configuration possible on main boards with on-board LAN. These are
pre-configured for
• 19200 baud,
• 8 data bit with no parity and
• one start bit and one stop bit are always used (not selectable).
