2.3.3 RS 232 Interface
The A150 features a standard RS-232 serial interface suitable for connection to a
PC or host system. The communication protocol is extremely simple to facilitate
readback and control with readily available terminal programs such as
Hyperterm. The RS-232 link has the following parameters:
Baud rate:
19200
Data bits:
8
Parity:
none
Stop bits:
1
Flow control: none
An example configuration using HyperTerminal on a PC is shown in figure 2.2.
