the Ethernet port of a computer (using an Ethernet
crossover cable).
o
Web Server allows configuration via the network using
any web browser.
o
Telnet allows configuration via the network by accessing
the setup configuration menu.

• Virtual COM Driver Software for Windows - installs virtual
COM ports, viewable in the Windows Device Manager under
Ports (COM & LPT). Virtual COM port provides access to any of
the ports on the ESP901 and ESP902, like any other serial port
(legacy, PCI, USB or PCMCIA) on the computer. Any program
running on the computer and using Windows-based COM ports
can access the serial devices attached to the
Serial Server. The
LAN becomes transparent to the serial device and the software
running on the PC.
• Heart Beat Connection - selectable protocol ensures reliable
communications in Virtual COM Port or Paired Connection
modes. This feature restores the connections if communications are
temporarily lost at either end due to loss of power or the Ethernet
connection.
