Shimadzu GC-201x
3 Installation Procedure
3 Installation Procedure
3.1 Hardware - Wiring
Start and Ready signals are communicated with
Clarity
through the Serial
cross DB9F- DB9F cable, so it is not necessary to connect additional
starting cables. The signal cable has to be connected according to the
following scheme.
In a set with the
Autosampler
synchronization cables might be necessary.
Note:
Typical connections of a set with Autosampler can be found in the
Getting
Started
manual (chapter
Device Setup and Wiring
).
Typical serial cable wiring is described in the picture.

3.2 Shimadzu GC-201x setup - communication
The GC must be fully configured prior to connecting to
Clarity
. No special
settings have to be made on the
Shimadzu GC-201x
chromatograph, only
the communication protocol of the instrument (set on the FUNC key
screen
by using
6. GC
CONFIGURATION
- 3. TRANSMISSION
PARAMETER) has to be set to
LEVEL3
. Baud rate set in the instrument
must correspond to the
Baud Rate
set in the
Shimadzu GC-201x Setup
dialog. For locally connected instruments with short interconnecting cable
the
Baud Rate
set as default (
115200
) is recommended. With the rising
length of the cable or when connected via the network the
Baud Rate
should be set lower. Maximum
Baud Rate
depends on the length of cable
and its capacitance. For standard type of cable recommended maximum
Baud Rate
is following:
Length of the cable
Maximum recommended speed
3 m
115200 bps
6 m
57600 bps
15 m
19200 bps
Note:
When controlling
Shimadzu AOC20
autosampler, a separate serial line
is required, connecting the autosampler directly to PC.
