Serial COM ports

The AM335x processor provides 6 high-speed, fully functionally compatible 16550 serial UARTs on the
ReliaGATE 10-10. Four of these channels can be used as follows:

General purpose I/O

The following General purpose I/O, provided by the AM335x processor, are available on the screw terminal
block.

Relays

• Relay 1 uses GPIO64
• Relay 2 uses GPIO97

Optoinsulated inputs

• OPTO 1 uses GPIO103
• OPTO 2 uses GPIO104
A simple Linux BASH script called am335x_gpio simplifies the access to GPIO.
