AIC 5000 Installation and Configuration

Configure the SS420x
If you will be using an SS420x attached to the AIC (used for analog
acquisition), it will need to be configured locally. If you are not using a
local SS420x, you may skip this section.
1.
Start the data system software by clicking
Start > All Programs
> Chromatography > EZChrom Elite
.
Go to Tools, Interface
Configuration and select the SS420x.
2.
From the SS420x configuration dialog, select the Serial port to
which the SS420x is connected and then select the
Installed
check box to enable the configuration of the interface. Then
proceed to select the appropriate settings for the interface.
Baud Rate
The communication baud rate is displayed here. To change
the baud rate, click
Advanced.
SS420x Advanced Port Configuration
The Advanced – SS420x Port Configuration dialog box
enables you to set the baud rate for the SS420x interface.
Click
Auto Detect
to determine the current baud rate
setting. Click
OK
to exit.
Base Frequency
Select the base frequency. The default setting for the
SS420x is 10 Hz, which gives optimal signal to noise, and
can be used in countries using either 50Hz or 60Hz. The
base frequencies available will depend on the baud rate
chosen. If the baud rate is less than 38400bps, the base
frequencies 100 and 120 will not be available. If you choose
a higher base frequency, you must select a base frequency
which can be evenly divided into your line frequency (i.e.
30 for 60Hz countries and 25 for 50Hz countries). If
selected incorrectly, you may see line frequency noise on
your chromatogram. For best performance, select a base
frequency close to the maximum sampling frequency you
will be using to acquire data.
