The serial connection is an ordinary asynchronous receiver/transmitter
(RS-232). The serial port is initialized in Alpha RT as follows:
– 1200 baud if printer or Alpha ID II is connected
– 9600 baud if Dataview (or Alpha ID) is connected (in SETUP
parameter i =2)
– 8,N,1 (8 databits, No parity [always 0], 1 stop bit)
The effect of the 'no parity bit' and the stop bit is a total of two stop bits, so
receiving end must be configured correspondingly.
The data bytes are:
start 8-bit data 1 stop
The data can be received with a communications program, for example
Windows (Hyper)Terminal, to PC and printed afterwards on paper, or a
printer can be directly connected to the port.
