Ultrasonic milk analyser
8. ADDITIONAL POSSIBILITIES OF THE ANALYZER
8.1. Connecting to 12 V DC power supply.
If there is a need the analyzer to work on place without electrical supply
available, then it could be powered by car battery or other 12 V DC external
power supply. Use the 12 V power supply cable (art. number 90-1801-0009,
Parts and Accessories, point 15).
8.2. Connecting to IBM PC
The analyzer can be connected to IBM PC using the RS232 interface cable
(art. number 90-1801-0010, Parts and Accessories, point 16). In order to
make the connection: switch off both the milk analyser and PC. Connect the
RS 232 cable towards Serial interface and towards the computer. Turn on
both analyser and PC. Now the device is ready to communicate with IBM PC.
8.3. Connecting a printer (option).
In order to print out the measurement results, a serial printer could be
connected to the device – for example ESC/POS Serial printer, production of
Datecs or Seiko. The interface connector for the printer is on the rear panel of
the device – “Serial printer output”. The printer (if it is Datecs), should be
connected to the “12 V printer output” on the device rear panel. Connect it via
cables, delivered by the company-producer. If the printer is connected directly
to the electrical network, then the analyzer and the printer should be
connected to one and the same electrical phase.
Communication parameters: 9600 bps, No parity, 8 bits, 1 stop bit. It’s one-
way communication (uses one line) – the analyzer only sends and the printer
only accepts data.
8.4. Working with external keypad (option).
It is possible external keypad (supplied by the producer of the device) to be
connected to the device, using special cable to the serial printer connector. In
order to connect external keypad to the milk analyzer, follow the procedure
below:
1. Connect the keypad towards connector labeled Printer.
2. Connect the printer towards connector labeled RS 232.
3. Forward the printer towards output RS 232, doing the following:
a. Press the button Enter (on the front panel of the analyzer).
b. While holding it pressed, switch on the analyzer’s power supply.
c. Release the button Enter.
d. Using the buttons Up/Down choose menu Settings and press
Enter.
