Question #: 962

Question: The parallel break out board on the Blacktooth machine has the parallel 25 pin socket, and also a usb socket. Should this usb socket be connected to the computer's usb port as well as the printer cable being connected to the printer socket?

Current Solution

The parallel breakout board has the db25 connector for data and the USB connector for power. Connect the USB from the computer to the parallel breakout board so the breakout board will have 5V of power coming from the computer. The db25 connector (connector with the 25 pins) receive data signals for each pin from 1 to 17 and have respective numbered screw terminals, some for input and some for output (18 to 25 are gnd pins).
