5.0 Serial Mode: Remote Control by PC: Printer & PC Control
Serial Mode (See Setup: Serial Mode, Section 4.6) allows you to choose between two different
methods of remote control and output for your VitaPump; Printer or PC Control.
Both methods allow you to control the VitaPump via RS-232 with a PC. You can upload flow rate,
direction and batch weight limits. You can also start and stop the pump with single letter
commands. The main difference between the two methods is in the output provided by the
VitaPump to the PC.
In Printer Control, the output is identical to that of the printer, as shown in Section 4.4 of this
manual.
In PC Control, you have an additional Print Command (P) available that returns a single line data
string that has no labels. This type of data stream is easily captured and placed into a spreadsheet
or similar report. Please see the example in Section 5.2 that follows. This method of control is
commonly used in conjunction with a control program written by a third party.
You can use Win95 HyperTerminal (Windows 95/98) for uploading of VitaPump control parameters.
Use the instructions (on the next pages) for accessing the HyperTerminal in your PC and for
selecting the appropriate parameters.
Once you have selected the HyperTerminal parameters, reduce the HyperTerminal window to one
half of its original size. Open Note Pad (“Accessories” or “New Text Document” in HyperTerminal),
reduce the Note Pad window to one half size. The Note Pad is used here as a text editor. Place the
HyperTerminal window in the upper half of your monitor and the Note Pad window in the lower half
of the monitor. Both windows are now displayed and are readily accessible.
5.0 Printer: Commands & Data format
If you have selected PRINTER in Setup: Serial Mode, the VitaPump will recognize the following
uploaded commands, and download metering data to and from your PC. The format of the
PRINTER download is identical to the printer output detailed in section 4.4 Setup: Printer on the
previous page.
Uploading a program from your PC to the VitaPump is straightforward: Create a program in the in
Note Pad. Make sure the first line of the program is an upper case “ U ”; the last line of the program
must be “ End ”. If you wish to execute the program, send the single character “ R ” for “RUN”. Each
program statement must be followed by a carriage return (“Enter”). For example:
U Initiates Uploading
RATE 6.0 Pump Rate of 6.0 g/min
CW clockwise, CCW for counter clock-wise
WGT 12.50 Sets Batch Weight to 12.50 kg (x.xxx kg or xx.xx kg)
END End of Program & “Enter”
R “RUN”, Executes Program
Use the following single character commands for Start / Stop
R for RUN
S for STOP
For example, if wish stop the vitamin metering, simply send “ S ” for STOP, if you wish to continue,
send “ R ” for RUN.
