| How do I externally power my port powered converter if I do not have handshaking lines? | |||

Solution:
Pins 1,4, and 6 can be used to externally power the unit. You must current limit power. A 7-12VDC is required. For example if you use 12VDC you would need to use a 170ohm resistor in series with your power.
