D Series Syringe Pumps
Section 6 Serial Interface
6.3 User-written Software When designing software to control the D Series pumps, you
must follow the DASNET communications protocol. This protocol
allows a number of instruments to be controlled from a single
RS-232-C serial port. Up to nine D Series controllers may share a
single serial data channel, with each controller only accepting
commands that are meant for it. Each pump controller can then
control up to three pumps each. Figure 6-1 shows a simple
system where the PC is connected to the serial port on the rear
panel of the pump controller (shown sitting on top of the pump
module). The pump control cable is attached to the pump A connector
on the rear panel of the controller.
6.3.1 DASNET DASNET converts your direct serial commands into a form recognizable
to our instruments. Using a computer language such
as C or BASIC, serial commands can be entered, converted, and
then sent to your instrument.
Table 6-2 is an example BASIC language program which performs
the required portion of the DASNET serial protocol.
Table 6-3 is an example of a C language program which does the
same. Both of these programs, including a DASNET serial driver
written in Visual C++, are available on CD-ROM (P/N
60-1245-096) in the sleeve at the back of the printed manual.
