3.4.7 RS485

One RS485 from P29 is available on carrier board, designed with 1500VDC electrical isolation and

ESD4 solution. MAX13487 can control transceiving direction automatically. P28 is short circuit

jumper for 120

Ω

resistor of AB wire. and we kindly suggest users to take it common-grounded

when using it for communication.

3.4.8 SPI

P40 on carrier board is a simple horn seat from ECSPI2.
