Connecting to the Host’s RS-422A/485 Port

When an NT-AL001 Link Adapter is being used, the RS-232C cable can be con-
nected to either serial port A or B on the NT21.
When an NS-AL002 Link Adapter is being used, the Link Adapter connects di-
rectly to serial port B on the NT21, so an RS-232C cable is not required.
