Serial Port Interfaces - X5/X11/X13/X15; Gpio And Ad/Da Interface - X7 - Kontron MSM-LP User Manual

3.2.3 Serial Port Interfaces – X5/X11/X13/X15
Four serial ports for asynchronous serial communication are defined. By default, they all support TTL levels. An
external conversion to RS-232 and RS-422/485 is possible for all ports.
Note: A conversion to another voltage level (RS-232 or RS-422/485) is possible. The design must assure that a
placement option can bypass the level-shifters to meet the requirement that all ports support TTL levels.

3.2.4 GPIO and AD/DA Interface – X7
The board has a GPIO header interface with additional AD/DA channels. Any filtering must be done externally.
