Introduction

The DS202R is a dual-use device: depending on the loaded firmware it can work as a fixed-function, ready-to-run serial device server (default) or BASIC-programmable controller.

As a serial device server, the DS202 allows you to quickly network-enable practically any serial device or system.

As a BASIC-programmable controller, the DS202 offers a low-cost, rapid development alternative to expensive and complex computing platforms, such as LINUX-based boards.

The DS202 is internally based on the EM202-EV Ethernet-to-Serial Board (and EM202 module).

Hardware Features

• Stylish and very compact, external dimensions only 60x47x30mm.
• Extended power supply range: 10-25VDC.
• One 100BaseT Ethernet port.
• One RS232 serial port (TX, RX, RTS, CTS, DTR, DSR).
• Six LEDs display status information.
• Internal firmware is upgradeable through the serial port or network.
• DS202-KIT Starter Kit available.
• CE- and FCC-approved.

Serial Device Server Features

• RTS, CTS, DTR, and DSR lines can be used as remotely controlled I/O.
• 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...
