* The +5V line is not used when connecting to a P.C. However it can be used to power a Hand Held Terminal
Device.
The RS232 Cable shield should be connected to the metal body of the D-Type connector.
NOTE:- The +5V line on J4 is rated to operate at 100mA. If the current exceeds
this amount then a resetable fuse will open. When the excessive current drain is
removed, then the +5V line will be able to source current again.
