1, 2, or 4 Port Industrial Ethernet Serial Servers allow connection of RS-
232, RS-422 or RS-485 devices to an Ethernet network. The serial ports can
be accessed over a LAN/WAN using
Direct IP Mode, Virtual COM Port, or
Paired Mode connections. The 10/100 Mbps Ethernet connection auto-
selects 10BaseT or 100BaseTX and indicates the type of connection with a
bi-color link light. These serial servers are built for use in industrial
environments, featuring an IP30, approved slim line DIN rail mountable
case. They operate from a range of AC or DC power supply voltages, support
redundant DC power and feature terminal block power connectors.
Figure 1. 1, 2, or 4 Port Industrial Serial Servers
Features
• Multi-interface serial ports
The 1 Port Industrial Serial Server features one multi-
interface serial port and the choice of standard DB-9M or
removable terminal block connections (switch selectable)

The 2 Port Industrial Serial Server features two multi-
interface serial ports
The 4 Port Industrial Serial Server features four multi-
interface serial ports
All ports are software selectable as RS-232, RS-422, RS-485
full duplex or RS-485 half duplex interfaces
For all models Port 1 is software, or DIP switch selectable for
Console Mode operation (configuration via direct serial
connection)
• Slim line DIN rail mountable case
• Accepts AC or DC power over a wide volt range
• Redundant DC power supply input
• 10/100 Mbps Ethernet with Auto Selection
• LAN and WAN Communications
• TCP or UDP Client or Server operation - configurable
• Software Support - Windows 98/ME/2000/XP or NT 4.0
• Firmware Upload for future revisions/upgrades
• Configuration of Ethernet and serial port settings can be accomplished
using any of four methods:
Serial Server Manager Software for Windows allows
configuration via a network connection or directly from the
Ethernet port of a computer (using an Ethernet crossover cable).
Web Server allows configuration via the network using a web
browser.
Telnet allows configuration via the network by accessing the
setup configuration menu.
Console Mode allows configuration through an RS-232 serial
port in using a VT100 Terminal Emulation program and an RS-
232 crossover cable.
• 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 Serial
Server
, 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.
