Asynchronous Data Transmission
2.1
Asynchronous Characters
Data characters can be transmitted either in 10 or 11 bits and either in 8 or 9 bit data
characters between the start and stop bits respectively. These options are factory set. Thus,
they have to be decided in advance.
Characters are formatted in accordance with the ANSI standard asynchronous characters.

Data transmission between the radio data modems is synchronous. The radio data modem
corrects the time difference between a clock signal from the data transmitting equipment
