SyriXus Series Pumps Installation and Operation Guide
Section 8 Serial Interface
8.1 Overview The Teledyne ISCO SyriXus series syringe pumps can be remotely
controlled by a computer through a built-in RS-232-C serial or USB
interface. This function is supported by the Teledyne ISCO
LabVIEW™ toolkit.
You can write your own custom program to control Teledyne ISCO
syringe pumps using any suitable programming language, such as
BASIC or C++. This section provides the syntax and responses for
serial commands. Simplified examples of programs are also provided.
It is possible for you to write custom programs capable of controlling
up to seven controllers from a single computer, each with up to four
connected pumps. Writing programs for serial control requires sub-
stantial knowledge of the software language used, consequently
Teledyne ISCO does not provide support for developing your own pro-
grams, because of the large range of programming languages.
The toolkit contains a sample program capable of running one con-
troller and one to three pumps. Its primary purpose is to provide an
example to help the programmer start constructing custom programs
for individual pump systems and applications. To modify the program
in any way, you must have the complete LabVIEW Compiler, available
from:
This section of the manual provides detailed information about:
• Cable connections for serial control
• Setting up the controller(s) for serial control
• DASNET Protocol
• Serial Commands
8.2 Network Control
and
Communication
Network communications are always initiated by the network con-
troller, which is typically a personal computer or laptop. Messages
from the instruments are in response to messages from the network
controller. All information on the network is transmitted as groups of
ASCII characters called frames. The message frames contain the
origin of the message, the destination of the message, and a checksum
to verify the validity of the message.
