In order to use the button instead of the antenna, the R52 resistor (near the microUSB connector, on the bottom side) has to be soldered to the board.
#### RS232 ports The device has 2 independent RS485 ports. [](https://doc.redisage.com/uploads/images/gallery/2024-06/1qnimage.png) #### RS485 ports The device is equipped with two MAX481 transceivers that enable communication in the RS485 standard on two channels independently. [](https://doc.redisage.com/uploads/images/gallery/2024-06/Ei3image.png)As the RS485\_1 / RS232\_1 and RS485\_2 / RS232\_2 standards use common microcontroller serial ports, it is possible to use only 1 interface from the pair at a time.
#### ETHERNET In order to support the Ethernet network interface communication, the network adapter available in the kit must be installed on the module (pay attention to its correct installation). This interface is supported by the external IP101G physical layer which communicates with the ESP32 microcontroller.
