Setting the RS-232/422 DIP switch
Set the stop bits, data bits, parity, and baud rate on the RS-232/422 DIP switch, located on the front
panel (see FIG. 1 on page 1). The AXB-232++ supports the following asynchronous data
standards:
Stop bits 1 and 2
Data bits 7, 8, and 9
Parity None, Odd, Even, Mark, and Space
Baud rates 300, 600, 1,200, 2,400, 4,800, 9,600, 19,200 and 38,400.
57,600 is achieved by setting the DIP switch to 300 baud, and using the
’
BAUDMED
’ Send_Command (see the Send_Commands section on page 9 for
details).
115,200 is achieved by setting the DIP switch to 300 baud, and using the
’
BAUDHIGH
’ Send_Command (see the Send_Commands section on page 9 for
details).
The table below shows the RS-232/422 DIP switch numbers, functions, and their corresponding
values.
