4. Cavo di collegamento tra terminale e stampante seriale
(a cura del cliente).
5. Stampante seriale (a cura del cliente).
6. Cavo AWG20/22 per connessione in pLAN tra più schede pCO.
Hardware Structure
The hardware structure is the following:
1. User terminal with keypad, display and signal LEDs.
2. Main board with microprocessor, EPROM containing the
application program, input/output terminals.
3. Cable for connecting the terminal and the main board.
