9.5 Getting Started With RS-232

Before beginning to develop pump control software for a computer, first setup and experiment with the
pump’s communication. After attaching the pump to the computer, run a terminal emulation Program on
the computer. A generic terminal emulator, supplied as standard software with many computers, can be
used to communicate with the pump in the Basic communications mode.

Next Advance supplies a terminal emulator, for demonstration purposes only, which allows more complex
control of the pump. Also, this terminal emulator contains a “Pump Programming Language” (PPL™),
which allows Pumping Programs to be developed using symbolic text, modified, and stored in computer
files, then downloaded to the pump.

With a generic terminal emulator, setup the terminal emulator with the same baud rate as the pump and
with an 8 bit data, no parity, and 1 stop bit (8N1) data frame. Set the communications port to the port that
is attached to the pump. Also enable local echo (half-duplex) and turn flow control off.
