SW1-5

RTS-D Disable RTS control for RS-485/422 driver

RTS-E Enable RTS control for RS-485/422 driver

RTS control method allows the connected RS-232 device (such as a PC) to control RTS signal (CTS input at the converter end) by software to enable or disable RS-485/422 driver. [RTS-D] setting is used to disable RTS control method.

SW1-6

RXC

RS-485/422 receiver enable control by RTS or ADC

RXE

RS-485/422 receiver is forced to enable.

[RXC] setting enable to use the same [TXC] logic but reverse it as RXC for the RS-485/422 receiver control. It means when the driver is enabled the receiver is disabled. The receiver is enabled when the driver is dis- abled. This setting is applied when a half-duplex communication is adopted.
