Mini-PCIe Socket
Software Programmable RS232/422/485 Serial Port (J11)
A RS232/422/485 serial port is available through a 5-pin header in a 1x5 configuration
with 2mm spacing. The mating connector is a JST PAP-05V-S, available from Digi-Key
as part number 455-1489-ND. The mating connector pins are JST SPHD-002T-P05,
available from Digi-Key as part number 455-1313-1-ND.
● GPIO[4]:DIO[0] selects between RS232 and RS485
○ 0 = RS232
○ 1 = RS485
● GPIO[1]:DIO[0] selects UART_TERM (RS485 Termination)
○ 0 = No termination for RS485
○ 1 = 120 Ohm termination for RS485 RX and TX
● GPIO[4]:DIO[2] selects UART_HALF ( RS485 Half or Full Duplex)
○ 0 = Full Duplex for RS485
