Introduction

The DS203 is a dual-use device: depending on the loaded firmware it can work as a fixed-function, ready-to-run serial device server or BASIC-programmable controller*.

As a serial device server, the DS203 allows you to quickly network-enable practically any serial device or system.

As a BASIC-programmable controller, the DS203 offers a low-cost, rapid development alternative to expensive and complex computing platforms, such as LINUX-based boards.

Hardware Features

• Stylish and very compact, external dimensions only 60x47x30mm.
• Extended power supply range: 10-25VDC.
• One 10/100BaseT, auto-MDIX Ethernet port.
• One RS232 serial port (TX, RX, RTS, CTS, DTR, DSR).
• Four LEDs display status information.
• Firmware is upgradeable through the serial port or network.
• DS203-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 data buffers (one in each direction).
• Onboard EEPROM stores user-configurable parameters (settings).
• Setup through the serial port or network (UDP commands or Telnet session).
• Over-the-network IP address configuration.
• "On-the-fly" serial port control commands.
• Serial-side commands to control network connections.
• 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". A LINUX version of the VSPD is also available.

BASIC-programmable Controller Features

• Executes your Tibbo BASIC application.
• Absolute flexibility - think of your device as a miniature computing platform.
• Supplied with TIDE (Tibbo IDE) featuring built-in debugger.
• Integrated web server supports dunamic 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...
