The DS203 is compatible with Tibbo Device Server Toolkit (TDST) for Windows. TDST includes the Virtual Serial Port Driver (VSPD), which enables you to use the serial port of the DS203 as a remote COM port of your PC. The Linux version of the VSPD is available as well.
The DS203 is the latest Tibbo Serial Device Server (replacing the Tibbo DS202) - New features include 100BaseT Ethernet port, large routing buffers, additional programming modes, wide supply voltage range and smaller external dimensions.
Internally the DS203 is based upon the EM203-EV Ethernet-to-Serial Board (and EM203 Module).
Fixed Firmware Features:
The DS203 is a Serial Device Server for external use. Device hardware includes one Auto-MDIX* 10/100BaseT Ethernet port, one RS232 serial port and an internal processor that "glues" network and serial sides together.
From the hardware standpoint, the DS203 can be viewed as a universal platform suitable for running a variety of network and serial communications-related applications. It is the application firmware, not hardware that gives the DS203 most of its functionality. The DS203 can run two distinctively different kinds of application firmware (version restrictions apply -- see below):
"Serial-to-Ethernet" firmware, currently in its 3rd generation ("Release3"), turns the DS203 into a ready-to-work serial-to-Ethernet converter that can connect almost any kind of serial device to the Ethernet (TCP/IP) network. This firmware has fixed functionality; you adjust the way the DS203 behaves by specifying the values of programmable parameters (settings) defined in this firmware.
The application firmware of the DS203 can be upgraded through the device's serial port or Ethernet port. Serial upgrades are facilitated by a so-called Monitor- a fixed "service" firmware inside the DS203. Network upgrades rely on the application firmware itself- there is a self upgrade algorithm that will be detailed later.
The DS203 is supplied with "serial device server" firmware pre-loaded. If you wish to receive the module with TiOS firmware, please specify option "P" device on your order. Alternatively, you can just load the TiOS firmware by yourself. Current firmware versions are posted on our website.
Firmware version restrictions
The DS203 uses newer DM9000B Ethernet controller (earlier Tibbo devices utilized an older DM9000A IC). Upgrade to the DM9000B required firmware changes which were made in V3.70 of the "serial-to-Ethernet" firmware and 2.05.10 of the "TiOS" firmware. Earlier firmware versions will not run on this module! If you have to stick to the older firmware, please use the DS203A device instead.
* Auto-MDIX means automatic detection of "straight" and "cross" cables.
