The 5001 allows your laptop or office PC to talk with remote devices up to 1.2km away in order to: - Check production status
- Control machinery
- Gather statistics
- Modify programs remotely
- Control industrial networks
- Control relays and read inputs
- Integrate with the Control-it I/O System
- Communicate with remote devices
The 5001 is easily our most popular product. It is flexible and easy to use. It provides a clean, reliable transmission medium, which is noise resistant. It protects the PC or PLC from damage due to High voltage, using optical isolation. It doesn't require specific software support to run. It has RXD and TXD lights making it easy to monitor communications passing through it. It requires no configuration and it is powered from the RS232 and RS485 ports. You can connect several 5001 converters to the same communications bus. It can run at any baudrate between 300 - 115200 Baud, and the baudrate is set automatically when data is received. It even has automatic flow control!

Why use a Technman Control-it Automatic Converter? Traditionally, the RS232 serial interface protocol is the only connection standard that has been adhered to by all computer manufacturers. However RS232 is only able to operate effectively where the computer and a single device connected to it are situated within a few metres of each other. Where information needs to be transmitted between multiple devices at distances of up to 1.2 kilometres remote from the computer, the RS485 protocol is able to achieve this economically using a 2 wire 'twisted pair' circuit. Technman's converters easily and economically provide the interface between your computer's RS232 port and the RS485 system. The RS485 communications protocol operates like a telephone party line. One device communicates at a time. The Control-it 5001 converter is designed to enhance your data throughput up to 80% over similar converters. Technman's automatic converters can do this because they have a very fast turnaround time. Alternatively, the Technman Control-it 5006 gives you seamless communication in both directions simultaneously (using a 4 wire system). The 5001 and the 5251 are called "Automatic" converters because they automatically detect the character being sent to them and enable communication the appropriate direction. In contrast, manual converters require the user to tell them when the RS232 device is transmitting by raising the RTS line. By using an automatic converter, you are ensured that your current software will continue to work. The following screen shots compare a character sent at 9600 bps, showing a conventional automatic converter versus the Control-it converter: 
| Fig. 1 A standard converter
Total time wasted is 1300uSec | Fig.2 The Control-it 5001 converter
Time wasted is less than 200uSec | Figures 1 and 2 show the RS485 signal. - To the left of point 'A', the RS485 line is floating and available to any unit on the line.
- Between points 'A' and 'B' a single data character is being transmitted.
- Between points 'B' and 'C' the party line is being held without any transmission taking place. This represents wasted time as no other unit can transmit without data being lost, even though the line not being utilised. Note that in Fig 2 this time has been reduced to less than 200uSec.
- To the right of 'C' the RS485 line is once again floating and available to any unit on the line to use.
The danger with a standard converter's wasted 1300uSec is that a remote device will respond before the RS485 line is available. Some remote devices can be programmed to wait longer before they respond, but this slows down the data transfer. This potential problem is eliminated with the Control-it converter, making setup and operation simpler and faster.
