Disable ADC control for RS-485/422 driver

SDE

EnableADC control for RS-485/422 driver

ADC method involves special circuitry that senses when data is received on the RS-232 interface and is being transmitted and automatically en- ables the RS-485/422 driver as well as disabling the driver within one character length of the end of transmission. This is a useful method for driver control since it needs no software involved.

In order to obtain an optimal performance, set SW2-2 ~ SW2-8 the asso- ciated timing parameter for each RS-232 baud rate.
