Network Connectivity
❏
If you have a NIM (Network Interface Module) board, the
terminal has a serial port, a parallel port, and either a thin
or twisted-pair Ethernet connector.
Communication Methods
NCD terminals can communicate over a LAN or serial
connection in various ways:
❏ Over Ethernet using TCP/IP or DECnet/NCDnet
protocols. TCP/IP and DECnet can be used concurrently.
❏ Over Ethernet using the LAT protocol, typically
supported by Digital hosts.
❏ Over Token-Ring using TCP/IP.
❏ Over a serial connection (or a LAN) using NCD’s
XRemote software.
Serial Connection
NCD terminals can have up to three serial ports with RS-232 C
connectors. The ports are used for:
❏ Local or remote serial connections.
❏ XRemote, the NCD software for running X over a serial
connection. For information about XRemote, see Chapter
12, Using XRemote.
❏ A printer or any serial input/output device
Parallel Connection
HMX, Explora, Explora Pro, Explora 400/450 series, and
Explora 700 terminals and interface boards include an
industry-standard Centronics-compatible parallel port. The
parallel port supports output devices only. You can attach a
printer or floppy disk drive to the parallel port.
