Introduction

The EM120 serial-to-Ethernet module is an upgrade of Tibbo's original EM100 device. The device features larger routing buffers, additional I/O lines, and a number of other improvements. To achieve smaller dimensions, the module doesn't have Ethernet magnetics onboard.

Hardware Features

• Compact, dimensions only 35x27.5x9.1mm.
• Low power consumption of 50mA@5VDC
• Fully sealed design.
• One 10BaseT Ethernet port; magnetics not built in.
• One serial (TTL) port (TX, RX, RTS, CTS, DTR, DSR).
• x5 additional I/O lines.
• Four LED lines provide module status information.
• Internal firmware is upgradeable through the serial port or network.
• EM120-SK Starter Kit available.
• CE- and FCC-approved.

Firmware Features

• All I/O lines can be used as remotely controlled I/O.
• Full- or half-duplex operation for serial (TTL) port*.
• 8KB routing buffers (x2, one in each direction).
• Onboard EEPROM stores numerous user-definable functioning parameters (Settings).
• Setup through the serial port or network (UDP commands or "Telnet" TCP session).
• Over-the-network IP address configuration is also supported.
• Specialized "on-the-fly" commands for serial port control.
• "Modem" commands to control network connections; status commands for remote monitoring, etc.
• Direct control of ADSL modems.
• Supported network protocols include UDP, TCP, ARP, ICMP (PING), DHCP, PPPoE, and LCP.
• Supplied with the Device Server Toolkit (DST) for Windows. The DST includes Virtual Serial Port Driver (VSPD) , a.k.a. "COM redirector". LINUX version of the VSPD is also available.
• Works with the AggreGate system.
