Communication Protocol
7 Communication Protocol1
RS-232 communication between the 7408 and the PC is done using the following protocol. The protocol uses four bytes of information,
and data is at 9600 baud, no parity, 8 data bits and 1 stop bit. The controller and machine should be connected via a null-modem
connection, that is, if using a DB-9 port, connect as follows:
Connect pin 5 of the PC to pin 5 of the machine
Cross pins 2 and 3, i.e., connect pin 2 of the PC to pin 3 of the machine, and connect pin 3 of the PC to pin 2 of the machine
On the PC side, short pins 4 and 6
On the PC side, short pins 1, 7 and 8
