Note

There are two communications ports in NT20. Either of them can be set for
communications. But Port A can be set to communications with either the host
(Host link, NT link 1:1, NT link 1:N, RS-232C) or Support Tool and Port B can
only be set to communications with the host (Host link, NT link 1:1, NT link
1:N, RS-232C).
The NT20 can not communicate with both two ports at one time.
The factory setting has been made at "Port B".
Select the host communications port by the menu operation from the System
Menu as described below. (e.g., Host Link)
