It seems has no ability to drive port-powered devices or full length RS232 cabling. In order to fulfill this purpose, The RS232 Line Booster is used for cable extension, amplify (Boosting Low Power Ports) and filter data and handshaking signals.
This RS232 Line Booster internal circuit diagram shows the direction of flow on each line. Connect directly the male connector toward the computer and the female connector end should go toward a CRT, printer or any other interface.
And there is recommendation that extension cables be no longer than 50 feet (15-25 m).Complete your read of RS232 Line Booster Internal Circuit Diagram for Signal Flow Determination in the pdf filetype (source: bb-elec.com)
