SDD Disable ADC control for RS-485/422 driver
SDE Enable ADC 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.
SW2-2 1200 ADC Timing parameter for RS-232 baud 1200
SW2-3 2400 ADC Timing parameter for RS-232 baud 2400
SW2-4 4800 ADC Timing parameter for RS-232 baud 4800
SW2-5 9600 ADC Timing parameter for RS-232 baud 9600
SW2-6 19200 ADC Timing parameter for RS-232 baud 19200
SW2-7 38400 ADC Timing parameter for RS-232 baud 38400
SW2-8 115200 ADC Timing parameter for RS-232 baud 115200
