- For RS-485, TX+(pin 2) and RX+ (pin 3) must jumper together inside the D type connector.

- TX- (pin 1) and RX- (pin 4) is the same.

Transmit date control in half-duplex mode

In half-duplex mode, the transmission buffer must be controlled to prevent transmit data from causing a

collision. ATCA-1(SBC Board) uses the RTS signal and bit 1 in the modem control register to control

transmit data.

Modem control register

(Setting I/O address +4H) bit 1: 0 … RTS High (Disables transmission)

1 … RTS low (Enables transmission)

Setting the RS-422/RS-485 receiver disable control jumper

When the RS-422/RS-485 port is used, the RTS signal is used for driver enable control Connecting JP2

Pins 4 and 6 disables the receiver at the same time, preventing the port from receiving output data to an

external device.
