ASXPRESS PLUS Rapid Sample Introduction System Operator’s Manual
Chapter 7: Installing the Electronics Module
81
NOTE
The connection between the electronics module and the host computer is a
little different from connections to many other devices such as printers:
Two distinct connections are required.
You can use either serial (RS-232C) or a USB connections.
The USB connections behave like virtual COM ports. The cables cannot be
moved around from one port to another without changing the software
configuration.
Establishing an OEM COM Connection (RS-232)
The OEM COM connection conveys autosampler commands from the ICP
software on the host PC to the electronics module. These commands are then
re-issued, if appropriate, through the AUTOSAMPLER serial port.
The serial interface kit provided with the CETAC autosampler includes a serial
cable equipped with two female DB9 connectors. Use the interface kit to
establish a serial communications interface with the host computer. To do so,
complete the following steps:
1 Plug one end of the cable into the host computer’s serial (COM) port selected
for autosampler communications.
Make sure that the COM port you select matches the port selected in the
host computer’s ICP software.
2 Finger-tighten both screws of the cable adapter.
3 Connect the other end of the cable to the ASXPRESS PLUS OEM COM port.
4 Finger tighten both screws of the cable adapter.
