Introduction

oAll ports are software selectable as RS-232, RS-422, RS-485 full duplex or RS-485 half duplex interfaces

oFor 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/2000/2003/XP/ NT 4.0 and Vista

Firmware Upload for future revisions/upgrades

Configuration of Ethernet and serial port settings can be accomplished using any of four methods:

oVLINX ESP Manager Software for Windows allows configuration via a network connection or directly from the Ethernet port of a computer (using an Ethernet crossover cable).

oWeb Server allows configuration via the network using a web browser.

oTelnet allows configuration via the network by accessing the setup configuration menu.

oConsole 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.

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.
