2. CONNECTIONS OF THE RS-485 SHIELD

1 These jumpers are for determining the transmit pin (TX) and the receive pin (RX).

The upper row is connected to the TX line.

In the middle row each pin is connected to one digital pin of the Arduino (D0 -D7).

The lower row is connected to the RX line.

2 This jumper is used for direction control.

When the jumper is set to TX_CTRL as shown in the picture, the automatic direction control is

enabled.

If you set the jumper to D9_CTRL, you can control the direction manually with the digital pin D9.

A LOW signal must be applied to pin 9 for transmission and a HIGH signal for reception.

3 With this jumper the supply voltage can be changed between 3V and 5V.

This jumper must remain set to 5V for normal operation.

4 These connectors are used to send and receive the RS-485 signal.

Both connectors are connected to each other and transmit the same signal.

5 This button is used to restart the Arduino.
