How to Power the Converter from DTR and RTS Signals?
If you are using third-party software: look for Enable DTR, Enable RTS or similar settings. It is also possible that the software configures the DTR and RTS signals automatically. This can be verified by measuring a voltage greater than approx. 7 V on pins number 4 or 7 of RS232 with a multimeter (measured against terminal number 5, which is ground).
If you are writing your own software: configure the DTR or RTS signals to the active (L) level. For example, in the .NET (C#, VB) programming environment, these are the SerialPort.DtrEnable and SerialPort.RtsEnable properties, respectively.< /p>
