Note
PIN1/2 is TTL UART, PIN5/6 is RS232/RS485 interface, it is same UART for internal MCU, just
the hardware driver is different. Choose either TTL or RS232/RS485
2.4. RS232 Interface
RS232 don’t have hardware flow control function, and the physical voltage is ±8V.
2.5. RS485 Interface
RS485 use two wire links, A(DATA+), B(DATA-). Connect A(+) to A(+), B(-) to B(-) for communication.
Suggest to connect GND together when interference is very severe.
The RS485 interface support maximum 32 485 device, device. The cable maximum length is 1200
meters. Need to add 120Ohm terminal resistor for over 300 meters.
2.6. Mechanical Size
The dimensions of Elfin-EG4X are defined as following pictures(mm):
