The NT21 has the following two communication ports.

• Serial port A:

D-SUB 9-pin connector (female) For RS-232C only (The NT Support Tool and bar code readers can be con-

nected here, but an NS-AL002 Link Adapter cannot be connected.)

• Serial port B:

D-SUB 9-pin connector (female) For

RS-232C only (The NT Support T

Communication Methods That Can Be Used with the Host

The following communication methods

can be used with the hosts that can be

connected to the NT21.

• RS-232C

• RS-422A

• RS-485

The communications types that are actually supported vary with the host. For details, refer to Section 4 Connecting to the Host from the RS-232C Port and Section 5 Connecting to the Host from the RS-422A/485 Port.
