Introduction

Very compact and highly integrated, the EM202 Ethernet module features built-in Ethernet magnetics, RJ45 connector, and even four status LEDs! While being a true one-component Ethernet solution, the EM202 has a board footprint just slightly bigger than that of a regular RJ45 connector.

The EM202 is a dual-use device: depending on the loaded firmware it can work as a fixed-function, ready-to-run serial-to-Ethernet converter (default) or BASIC-programmable module.

As a serial-to-Ethernet converter, the EM202 allows you to quickly network-enable practically any serial device.

As a BASIC-programmable controller, the EM202 offers a low-cost, rapid development alternative to expensive and complex computing platforms, such as LINUX-based boards.

Hardware Features

• Compact, dimensions only 32.3x19x16mm.
• Power consumption: 230mA@5VDC.
• One 100BaseT Ethernet port
• Built-in magnetics and RJ45 socket.
• One serial (TTL) port (TX, RX, RTS, CTS, DTR, DSR).
• Four built-in LEDs display status information.
• Internal firmware is upgradeable through the serial port or network.
• EM202-SK Starter Kit available.
• CE- and FCC-approved.

Serial-to-Ethernet Converter Features

• All serial port 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.

BASIC-programmable Controller Features

• Executes your application written in Tibbo BASIC.
• Absolute flexibility - think of your device as a miniature computing platform.
• Supplied with TIDE -- a comprehensive development environment featuring seamless cross-debugging.
• Integrated web server (HTTP) with dynamic content generation.
• Numerous high-level objects speed up and simplify coding. Available objects include:
• Sock- up to 16 simultaneous TCP or UDP connections;
• Ser- UART communications;
• Io- control serial port lines;
• Stor- read to and write from the EEPROM;
• Romfile- add static (ROM) data to your project;
• And more...
