The EM202-EV is a100BaseT Ethernet to serial Board based on the EM202 Ethernet Module. The board offers a convenient way to test the EM202 and is also small enough to be used in production devices as a faster implementation alternative to Modules.

The EM202-EV is supplied in three versions (-RS, -TM, -TS) that differ in the set of installed components- see bottom of page for details. The Board can be used to create a standalone Device Server or it can be built into your serial device as a network communications board.

Hardware Features

• Compact, PCB dimensions only 52.6x38mm

• One 100BaseT Ethernet port

• Two power options: onboard power regulator with 9-24VDC input range (-RS, -TM) or direct 5VDC input (-TS)

• Optional onboard reset source with brown-out detection (-RS, -TM)

• Choice of RS232 (-RS) or TTL-level (-TM, -TS) serial port

• Two status LEDs on top of the Board* (-RS)

• Internal firmware is upgradeable through the serial port or network

• CE- and FCC-approved

Fixed Firmware Features

• Serial port includes RTS, CTS, DTR, and DSR lines; all lines can be used as remotely controlled I/O

• Two internal 4096-byte routing buffers

• Internal EEPROM stores numerous user-definable functioning parameters (settings)

• Supported network protocols include UDP, TCP, ARP, ICMP (PING) and DHCP

• Setup can be performed through the serial port or network (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 status monitoring, etc.

• Supplied with Device Server Toolkit (DST) for Windows, including Virtual Serial Port Driver (VSPD) (COM redirector)

• LINUX version of the VSPD is also available

• Works with TIBBO.NET

Programmable Firmware Features
(Tibbo Operating System)

• Code your applications in a BASIC-like language - Tibbo BASIC
• Comprehensive development environment with seamless cross-debugging (TIDE - Tibbo IDE)
• Absolute flexibility - the device is no longer a Device Server, but can serve many other functions (Programmable Network Controller)
• Integrated web server (HTTP) - create a web front-end for your device
• High-level objects, such as sock for socket communications and ser for serial port control simplify your code and allow you to create a data-transport application with just a few lines of code.

* There are also two Ethernet and two Status LEDs next to RJ45 connector on the EM202. Two optional LEDs on top of the board are connected in parallel with the Status LEDs on the EM202

Available EM202-EV versions (Ask for stock status: "RS" is typically in-stock, "TM" and "TS" ordered as required)

• EM202-EV-RS ("RS" stands for "RS-232") is intended for standalone designs, as it includes RS232 interface, switching power supply, reset IC, and "top" status LEDs. This Board can be used, for example, to build an external Serial Device Server, akin to Tibbo's DS100

• EM202-EV-TM ("TM" stands for "TTL Master") is intended to be installed inside your serial device (piggyback on top of your device's main PCB). The board has a TTL serial interface, and also can provide regulated 5VDC power (up to 100mA) and reset to your board

• EM202-EV-TS ("TS" stands for "TTL Slave") is also intended to be used inside your serial device, but it doesn't have a power regulator and reset IC so your serial board must provide 5VDC power and a valid reset signal
