CAN Connector
The CAN is a high speed communication interface. It is a two-wire serial bus
system supporting data communication with realtime requirements. This
CAN interface is used to connect the handheld controller of the Agilent
8453E UV-visible spectroscopy system to the spectrophotometer.
RS232C Connector
The RS232 is designed as DCE (Data Communication Equipment) with a
9 pin male SUB-D type connector. When controlling the spectrophotometer
through the RS232 interface, the connector needs to be activated and
configured by the 8-bit configuration switch next to the GPIB connector. For
switch settings, refer to Chapter 6 “Interfacing”.
Using a serial/parallel printer cable, an HP printer can be connected to the
spectrophotometer. This option is only used by the Agilent 8453E UV-visible
spectroscopy system. The 8-bit configuration switch has to be set to GPIB
communication and not to RS232 communication.
