The DS203 is an Ethernet to Serial (RS232) Bridge Device Server with Enclosure for standalone use. The device hardware includes one 10/100BaseT Ethernet port, one RS232 serial port and an internal processor that "glues" the network and serial sides together. Use the DS203 to network-enable nearly any serial device or system.

Hardware Features

• Stylish and very compact, external dimensions only 60 × 47 × 30 mm
• Extended power supply range: 10-25V DC, 400mA (12V nominal)
• One 10/100BaseT Ethernet port, auto-MDIX
• One RS232 serial port (TX, RX, RTS, CTS, DTR, DSR)
• Four LEDs display status information (two on top of device; two on RJ45 jack)
• Internal firmware is upgradeable through the serial port or network
• CE and FCC approved

Fixed Firmware Features

• Full- and half-duplex serial port modes
• Server, client, and server/client network (routing) modes
• RTS, CTS, DTR, and DSR lines can be used as remotely controlled I/O
• Extended 16KByte internal routing buffers (8K per direction)
• On-board EEPROM stores numerous user-definable functioning parameters
• Setup configuration through the serial port or network (over-the-network IP-address configuration is also supported). Network setup can be performed using UDP commands or Telnet TCP connection
• Specialized "on-the-fly" commands for serial port control, "modem" commands to control network connections, status commands for remote status monitoring, etc.
• Direct control of ADSL modems
• Supported network protocols include UDP, TCP, ARP, ICMP (ping), DHCP, PPPoE, LCP
• Works with Tibbo Device Server Toolkit (TDST) for Windows, including Virtual Serial Port Driver (VSPD) (COM redirector)
• Linux version of the VSPD is also available

Programmable Firmware Features
(Tibbo Operating System)

• Code your applications in Tibbo BASIC and/or Tibbo C
• Comprehensive development environment with seamless cross-debugging (TIDE — Tibbo IDE)
• Absolute flexibility — the DS203 can be used not just as 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

Note: This unit requires a power supply, which is not included. A suitable power supply can be selected as an add-on option from the bottom of this page. The DS203 power connector is a coax/barrel type of connector with 3.5mm outer and 1.35mm inner diameter. The center pin is positive, outer contact is GND.

If you want to get one of the DB9-to-Terminal adapters shown in the options below, the normal version (as opposed to inverted) is recommended as it will make the terminal connections face up and be more easily accessible.
