Clears program memory and resets communication parameters to Basic mode and address 0.
This is a special system command that will be accepted by the pump regardless of its current address.
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.
New Era Pump Systems Inc. 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
uploaded to the pump. In addition, a Pumping Program generator spreadsheet is available to assist in developing a
Pumping Program and to create the text file for uploading to a 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.
From the terminal emulator, you can interactively control the pump by typing in commands on your computer and
seeing the pump’s responses on your screen. This will give you a feel for how the commands work in addition to
allowing you to quickly develop the control sequence that will eventually be coded into the software being
developed.
The final benefit of using a terminal emulator is the elimination of several variables if the control software does not
work properly. If the pump works correctly with the terminal emulator, then this verifies that the hardware is
working properly and will work with any software. Any communications problems can then be narrowed down to
the control software.
Note on USB: If an RS-232 port is not available on your PC, the pump may be operated through a USB to RS-232
converter cable (available as an accessory, part #CBL-USB232). This cable attaches to the standard RS-232 to PC
cable (part #CBL-PC-PUMP-7). The PC will create a virtual RS-232 communications port that communicates
through the USB to RS-232 converter cable. The terminal emulator can communicate through this virtual port.
