Note that these instructions refer to the Epson LX300 printer with the optional serial port fitted.
If a printer cable provided by the BioTector manufacturer is used, the electrical connections are as follows:
- Terminal TX on the microcontroller is connected to pin 3 on the D25 plug.
- Terminal RX on the microcontroller is connected to pin 2 on the D25 plug.
- Terminal GND on the microcontroller is connected to pin 7 on the D25 plug.
- The cable should be screened and the screen earthed at the printer.
The BioTector uses the factory default settings on the Epson LX 300. Thus, when the printer is connected to
the BioTector and the BioTector port is switched on, the printer should begin to operate immediately. For
details on changing the settings on the Epson LX300, see the printer manual.
The procedure for connecting the printer to the BioTector is as follows:
1. Connect the printer RS232 cable.
2. Switch the printer on.
3. In BioTector’s Data Program, Printer menu, set the PRINT MODE to STANDARD.
The BioTector will print the analysis data conforming to the headings of the selected mode at the end of each
reaction.
