Shimadzu AOC-20 1 Shimadzu AOC-20i/s Control module
1 Shimadzu AOC-20i/s Control module
This manual describes the setting of the Shimadzu AOC- 20 i/s/d
autosamplers. The control module enables direct control of the instrument
over serial line.
Fig 1: AOC-20i
Direct control means that the autosampler can be completely controlled
from the Clarity environment. Instrument method controlling for example
the vials and further device specific functions (e.g. washing) will be saved
in the measured chromatograms.

Shimadzu AOC-20 2 Requirements
2 Requirements
Clarity Installation CD ROM with AS Control module (p/n A26).
Free serial port in the PC (fast - 16550 UART).
Note: Modern computers usually have only 1 (if any) serial(COM) port installed.
To use more devices requiring the port, the MultiCOM adapter (p/n
MC01) is available.
Serial cross DB9F-DB9F cable (p/n SK01).
Note: Cables are not part of Clarity Control Module. It is strongly
recommended to order required cables together with the Control Module.
Caution: We have experienced power sources (controller boards) with DB9F
connector on the back instead of normal DB9M connector. In that case,
serial cross DB9M-DB9F cable is necessary. Contact our support on
sales@dataapex.com to consult the correct wiring.

Shimadzu AOC-20 3 Installation Procedure
3 Installation Procedure
3.1 Autosampler Setup - communication
The autosampler communicates with PC using the RS232- compliant
serial cross DB9F-DB9F cable.
Fig 2: Serial cross DB9F-DB9F cable
The RS-232 cable is plugged in to the autosampler controller board (not
the tower) present at the back side of the GC, replacing the cable
connecting it to the GC in default setup, as displayed in the Fig 3 on pg 3.

3 Installation Procedure Clarity Control Module
3.1.1 Connections
Besides the serial RS-232 cable, the connections must be made between
the autosampler Start OUT/Ready IN connector and the appropriate
connectors on the GC to allow proper synchronization between the AS
and GC.
The Clarity Start (IN) input must be connected to the GC Start Out
connector.
The Clarity Ready (OUT) digital output is not used, the commands are
transmitted over the serial line.
Refer to Shimadzu manual for description of cables supplied with the
autosampler.
When autosampler has to be used with Shimadzu 201x series GCs (
2010, 2014, 2014C, 2014 APC/AFC), it is necessary to connect it to the
PC via separate serial line. The controller box is build in the
GC2010/2014 case, but to use the control from Clarity, the short serial
cable from the GC to the controller box needs to be disconnected and
replaced by a serial cable to the PC.

Shimadzu AOC-20 6 Troubleshooting
6 Troubleshooting
When the cause could not be discovered easily, the recording of
communication between Clarity and the autosampler can significantly
help the DataApex support to discover the cause.
The recording can be enabled by adding or amending the COMMDRV.INI
file in the Clarity installation directory (C:\CLARITY\CFG by default). The
file can be edited in any text editor (e.g. Notepad).
Following lines should be added
[COM1]
echo=on
textmode=on
filename=CommDrv_%D.txt
reset=off
Note: Instead of COM1 type the correct serial port used to communicate with
the Shimadzu AOC-20 detector.
Note: %D (or %d) in the filename parameter means that the log will be created
separately for each day. The reset=off parameter disables deleting the
content of the log each time the station is started during the same day.
The created LOG files will greatly help in diagnosis of unrecognized errors
and problems in communication.
Recording the communication related to instrument control is not
recommended to leave it on for prolonged periods.
