1: Introduction
1.1 Product Overview
The Lantronix ETSs (ETS4P, ETS8P, ETS16P, ETS16PR, ETS32PR, and ETS422PR) are Multiport
Device Servers that provide shared network access to terminals, devices, console ports, and printers for a
variety of network protocols and operating systems. The ETS supports the TCP/IP, IPX (NetWare), Local
Area Transport (LAT), AppleTalk (EtherTalk), and Microsoft LAN Manager protocols.
Lantronix servers store their executable software in Flash (rewritable) ROM, meaning that they do not have
to download software from a host each time they boot. Software must only be downloaded when a new
software version becomes available. See Appendix D for more information.
Note:
In this manual, all servers will be referred to as “the ETS” unless a distinction
needs to be made between models.
1.2 Protocol Support
The ETS supports five industry-standard network protocols:
TCP/IP
TCP/IP is a widely-used protocol that can be run on networks with Macintoshes, PCs, and Unix
workstations. Server support includes Telnet, Rlogin, DNS, and the LPR and RTEL printing sys-
tems.
NetWare (IPX/SPX )
NetWare allows devices attached to the ETS to act as networked printers. The ETS supports all Net-
Ware frame types: Ethernet v2, Native Mode (802.3), 802.2, and 802.2 SNAP. In addition, it sup-
ports both Bindery mode and NetWare Directory Services (NDS).
Local Area Transport (LAT)
LAT is a protocol developed by Digital Equipment Corporation for local network terminal connec-
tions and is supported on almost all Digital operating systems. It provides both logins to remote
hosts and host-initiated print spooling.
AppleTalk
AppleTalk allows networked Apple Macintosh computers to see devices attached to the ETS and
access them as they would any networked printer.
LAN Manager
The ETS allows devices on LAN Manager networks to access networked printers. Systems running
Windows NT can access the devices using the Digital Network Port for Windows NT or the Net-
BIOS protocol.
