required for the analytical instrument you are using, refer to the hardware or

Establishing an RS-232 Serial Communications
Interface
The serial interface kit provided with the ASX-112FR Autosampler includes an
interface cable equipped with two modular port adapters. Use the interface kit
to establish a serial communications interface with the host computer. To do
so, complete the following steps:
Plug one end of the cable into the host computer's serial (COM) port selected
for autosampler communications.
1
Make sure that the COM port you select matches the port selected in the host
computer's software.
Finger tighten both screws of the cable adapter.

NOTES
If a host computer serial port with a DB9F, a DB25M, or a DB25F connector (9
pin D-submini receptacle or 25 pin D-submini plug or receptacle) must be used,
use the mating connector from the Teledyne CETAC Technologies universal port
adapter kit. You can order the adapter kit from Teledyne CETAC Technologies or
purchase an adapter locally to convert the serial port to a DB9M. Do not use a
"null modem" adapter.
Ensure you are connecting the serial cable to the COM1 port. Connecting the
adapter to the Dilutor (COM2) port on the autosampler will cause a
malfunction.
When interconnecting any computing devices, keep the communications cables
away from sources of electromagnetic or radio frequency (RF) interference,
such as electric motors, transformers, fluorescent light ballasts, or RF energy
sources. Limit cable runs for RS-232C to less than 16 meters. If these conditions
cannot be satisfied, use low-impedance, fully shielded cables to provide
satisfactory operation. The cables are available from many sources, but you will
need to specify the correct mating connectors and "straight-through" (DTE-
DCE) wiring.
Connect the other end of the cable to the ASX-112FR COM1 port.
3
Ensure that you are connecting the adapter to the COM1 port. Connecting the
CAUTION
adapter to the AUX I/O port on the autosampler will cause a malfunction. The
autosampler AUX I/O port is used for communications to a device other than the
host computer.
Finger tighten both screws of the cable adapter.
