AMX AXC-232++ Setting the RS-232/422 DIP Switch, Stop bits 1 and, RS-232/422 DIP Switch Settings

Installation and Wiring

Setting the RS-232/422 DIP Switch

Set the stop bits, data bits, parity, and baud rate on the RS-232/422 DIP switch (see FIG. 1). The AXC-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 DIP switch numbers, functions, and their corresponding values.
