Note An NT-AL001-E Converting Link Adapter can be used to convert between
RS-232C and RS-422A/485. This Link Adapter requires a 5-V power supply.
Power is provided by the RS-232C port on the Serial Communications Board
when the Link Adapter is connected to it, but must be provided separately when
connecting the Link Adapter to other devices.
