8. ADDITIONAL POSSIBILITIES OF THE ANALYSER
8.1. Connecting to 12 V DC power supply.
If there is a need the analyser 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 30030).
8.2. Connecting to IBM PC
The analyser can be connected to IBM PC using the RS232 interface cable
(art. number 30012, 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 Com. Port 1 and towards the computer. Turn on both analyser
and PC. Now the device is ready to communicate with IBM PC.
For more
detailed information regarding milk collection data program see the file
resLS_SupLiters.pdf from the CD, accompanying the device.
8.3. Connecting additional serial printer (option).
The interface connector for the printer is on the rear panel of the device
(Com. Port 2). The printer should be connected towards it. Connect it via
cables, delivered by the company-producer. If the printer is connected directly
to the electrical network, then the analyser 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 analyser only sends and the printer
only accepts data.
8.4. Connecting matrix printer (option).
If the device is working n milk collection center, where work load is heavy,
and there are a lot of results to be printed out, we suggest an option
connecting standard matrix printer (paper expenses would be less, the
reliability better).
Interface connection with the printer is at the rear panel of the analyser
“Parallel printer interface”.
8.5. Connecting and 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 analyser, 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:
o
Press the button Enter (on the front panel of the analyser).
