... Note that there are some COM ports that use signal levels of less than () 5V. The DB-9 versions of this adapter will not work with such ports. The DS9097U-E25 adapter, however, will function in most cases if external power is supplied. Without EPROM programming, the external power may be anywhere in the range 9V. For EPROM programming the voltage must be at 12V in any case. Before using an externally powered DS9097U-E25 with a COM port of less than ( ...
