1.0 Introduction
The STE-10 Serial Access Unit is a low cost, compact, serial
access server or terminal server for connecting asynchronous serial
devices (RS-232) over Ethernet (10Base-T) using a TCP/IP protocol
stack. The STE-10 may operate in either a client mode or as a server,
allowing connection of serial data directly over a LAN or WAN.
Configuration may be performed either via the DB25 pin RS-232 port
with an ASCII terminal or via Telnet and Ethernet connection on the
RJ-45 LAN port. The serial port is DTE, which allows direct
connection to DCE equipment such as Modems. For connection to
other DTE equipment such as a PC or terminal, a NULL Modem or
crossover cable is required. One is provided with the unit.
