TIBBO DS100B:BASIC-programmable Serial Controller (RS232)

The DS100R acts as a “Serial Device Server”; it allows you to connect any peripheral with an RS232 output to an Ethernet LAN.
Communication with the peripheral can occur from any PC connected to the local network; furthermore, if the latter has an Internet connection, the serial device can also become accessible from any external computer.
In this way, it is possible to place the peripheral wherever you prefer, connect it via RS232 to the DS100R, and connect the latter to the LAN hub, using cables that, according to specifications, can even be up to 100 meters long.
The DS100R is equipped with a 10BaseT port to connect to the LAN at a speed of 10Mbit/s and an RS232 port to connect to the peripheral. It has a power jack for power supply (which is 12 V DC with a current consumption of 150 mA) and some LEDs to indicate the status of the device or the Ethernet connection.
It also comes with drivers for correct operation in a Windows environment and some management and programming software.

 

The applications in which it can be used are fundamentally of three types: the first is to connect a serial peripheral without modifying existing control software. The DS100R driver is indeed capable of creating virtual COM ports on the PC (VSPs-Virtual Serial Ports) which, from the point of view of the program and the user, behave like standard hardware COM ports, but which in reality transform data into TCP packets sent over the LAN that are then converted by the DS100R into serial format.
Alternatively, it is possible to easily create new management software, through which to communicate directly with the peripheral, without using VSPs. The DS100R uses UDP/IP and TCP/IP transmission protocols for which many programming languages and compilers (for example, Microsoft's Visual Basic 6.0) already have management plug-ins available. For VB6 itself, Tibbo provides a manual explaining how to communicate with the DS100R.
Finally, by using two DS100Rs, it is possible to connect two serial peripherals that use the Ethernet connection to create a “Virtual Serial Link”, i.e., a connection that appears to the peripherals as serial, but which in reality is based on Ethernet technology. For example, by connecting the first DS100R to a PC's COM port and the second to a peripheral's serial port, and connecting the two Ethernet interfaces via a direct RJ45 cable, it is possible to simulate a normal serial connection to the software, but one that actually exploits Ethernet technology and TCP protocols. In this case, it is not even necessary to use VSPs, but direct access will be from the hardware COM ports.
Furthermore, if you have an ADSL connection, you can connect the DS100R's Ethernet port directly to it; in this simple way, the peripheral becomes accessible from any PC connected to the Internet.
The DS100R is also characterized by 3 different operating modes:
-one for performing Serial-to-Ethernet conversion and vice versa (Normal Mode);
-one for programming it via serial port (Serial Programming Mode);
-one used to perform firmware upgrade (Firmware Download Mode).
The latter two are special modes that are not used for normal applications (however, clear and complete manuals are available for more details). The first is the most interesting and commonly used.
