Introduction
Overview
The ASX-520 SpeedShift utility lets you control autosampler settings such as
rinse pump timeout, rinse pump speed and axis speed.
Improved Productivity
The utility can shorten run times by increasing the speed of movement along
the X-, Y-, and Z-axes.
Improved Economy
The utility can reduce consumption of the rinse solution by slowing the rinse
pump speed. The rinse pump timeout eliminates rinse solution waste at the
end of a sample run—especially for instruments which return the probe to the
rinse station without turning off the pump.
Improved Carryover Control
The utility can address carryover concerns by increasing the rinse pump speed
to improve probe cleaning effectiveness at the rinse station.
Improved Cross-Contamination Control
The utility can reduce the speed of axis movement to reduce the potential for
droplet shedding, which can cause sample-to-sample carryover.
Getting Started
1
To use the utility, you will need to
Upgrade the autosampler firmware.
Information on the required firmware version is on page 6.
You can upgrade firmware by downloading it from a PC (see page 9), or by

Configuring the Autosampler Personality
1
Several different configurations, or personalities, are built into the
autosampler firmware. When you replace the processor module, this
personality may need to be set.
Connect a terminal emulation to the autosampler.
The autosampler can be controlled using a serial communications protocol.
See “Operating a CETAC Autosampler Using a Terminal Program” on page 51.
You can use any terminal emulation program, including:
2
 C-Term. (recommended) This program provided is on the software CD, and
runs on Windows 2000 and later.
 HyperTerminal. This program was supplied with versions of the Windows
operating system through Windows XP.
Enter the command
VER
3
4
5
The information returned will include the personality description.
If the personality shown is not appropriate for your autosampler, contact
CETAC to obtain the correct "SETTYPE" personality number.
Enter the command
SETTYPE=nnn
6
7
where nnn is the personality number.
Cycle power on the autosampler.
Verify the personality with the VER command.
To reset the firmware to the ASX-520 Standard configuration, two "~"
characters in succession should be sent. The system will respond with an
"OK:".

Setting the Pump
Speed Jumper
The ASX-520 SpeedShift utility can control the peristaltic pump speed. But the
pump speed can also be controlled by moving a jumper on the autosampler's
circuit board. The utility assumes that the jumper is set to the highest speed.
Therefore, it may be necessary to move the jumper.
What happens if the jumper is not set to the highest speed? The speed of the
pump will be less than the speed set by the ASX-520 SpeedShift utility. At lower
speed settings, the pump might not run at all because the voltage being applied
to the pump is insufficient for it to overcome friction.

power on the autosampler, then restart the utility.
Viewing the Current Settings
The ASX-520 SpeedShift utility displays four user selectable settings. Once
communications are established with the autosampler, the values displayed
here will display the current settings stored on the internal processor of your
autosampler.

Explanation of the Settings
Pump Timeout
Peristaltic pump timeout in seconds. The timeout controls how long the pump
will run when the probe is in the rinse station and no other commands are sent
to the autosampler. Setting the timeout to zero disables the timeout feature.
Default=0.
Pump Speed Level
Peristaltic pump speed. The pump speed can be adjusted between 1 and 10,
with 10 being the maximum speed. Default=4.
X/Y Axis Travel Speed
Speed of X- and Y-axis motion. The speed can be adjusted between 1 and 5.
Default=2 for non-high speed units. High-speed units have three factory
settings, corresponding with the DIP switch settings.

Explanation of the Controls
Initialize Communications
Sets up a communications channel between the utility and the autosampler.
Before pressing this button, check that that the proper COM port has been
selected.
Set
Sends the new settings to the autosampler. This process takes about 5-10
seconds. A small progress window will pop up to show the process.
Factory Reset
Configures the autosampler to use the original factory settings.
Test XYZ Speed
Exercises the autosampler in all three axes so you can see how speed changes
affect the machine.
Toggle Pump
Turns the pump on and off. Use this to test the pump speed. The pump timeout
does not apply when the pump is turned on using this button.
Determining the Best Travel Speed for Your
Application
For ASX-260 and ASX-520 autosamplers, it may not be possible to use the
highest speed setting. At higher speeds, the sudden acceleration and
deceleration may cause droplet shedding from the probe tip, causing cross
contamination.
ASX-520HS autosamplers use an advanced acceleration algorithm which
largely prevents these problems.
NOTE
Use caution when increasing the travel speed. Depending on the sample
matrix, faster speeds have the potential for droplet shedding from the sample
probe. Droplets could land in other samples or on nearby surfaces.

6 Operating a CETAC
Autosampler Using a
Terminal Program
CETAC autosamplers can be controlled using a serial communications protocol.
You can use any terminal emulation program, including:
 C-Term. This program is provided on the software CD, or it can be
downloaded from the CETAC Web site. It runs on Windows 2000 and later.
(recommended)
 HyperTerminal. This program was supplied with versions of the Windows
operating system through Windows XP.
This chapter explains how to operate a CETAC autosampler using either of the
two programs.
Using C-Term™
C-Term is a simple terminal program developed to validate the installation and
functionality of various CETAC devices. C-Term communicates through a serial
(RS-232) port on the host computer. If the device is connected to a USB port,
the device driver will create a virtual serial port.
C-Term is provided on the CETAC software CD.
Starting C-Term
1
2
Check that the communication port connectors are properly attached between
the host computer and the CETAC device.
If the communications interface between the CETAC device and the host
computer is not established correctly, the device will not function.
On the Start Menu, click All Programs, then CETAC, then Support Tools, then CTerm.

Figure 6-1 Starting C-Term
Overview of the C-Term Window
Once C-Term is loaded, the window shown in Figure 6-2 will open. The
majority of C-Term’s functions are available from this window.
Figure 6-2 C-Term Window
By default, typed commands are sent to the CETAC device connected to the
opened port. The typed commands will appear in light green in the terminal
buffer. Responses from the device will appear in red. Non-printing characters
such as carriage returns will appear as ASCII hexadecimal numbers
surrounded by square brackets, for example, [0D] is the carriage return
character.

shown in red
Configuring C-Term
By default, C-Term attempts to open COM1 the first time it is executed. If the
COM port that the CETAC device is connected to is not the default (COM1), then
it will be necessary to configure C-Term to use the desired port.
The default communications configuration is appropriate for use with the vast
majority of CETAC devices. Exceptions are the ASX-8000 which requires a baud
rate change and the AS300 emulator which uses non-printing characters are
part of its command protocol. Modifying the default settings is described
below.
NOTE
If COM1 (or the currently selected COM port) is in use by another program or
is otherwise unavailable, a warning dialog box will pop up when C-Term starts
stating that the COM port could not be opened.

ASX-520 SpeedShift Utility Upgrade Installation Guide
The window will close and the settings will be saved. These new settings
will be applied immediately and used thereafter unless changed again.
NOTE
All ASX-520 series autosamplers communicate at 9600 baud (which is the
default.)
NOTE
Only installed COM ports, including USB virtual COM ports, will appear in the
Comm Port menu.
Setting Preferences
