The model 81009 Interface powers itself from the signal lines of the serial interface and requires no additional external power supply when operated on standard RS232 interfaces.

If however there are supply problems due to low-power interfaces, it is always possible to externally power the interface with up to 9V using its handshake inputs, or to use fiber-optic interfaces having their own power supply (e.g. model 81201).

With model 81029 there is also a 9-pin special version available whose transmission distance is limited to from 0 to 20m, but which only places an approx. 2mA load on the connected RS232 interface. With this version it is also possible to run on lower power RS232 interfaces without the need for an additional voltage source.
