J3 and J4 Power Connections
The control board also has 2 power connectors, J3 and J4, which are powered by 7 to 18 volts DC at 100 mA. Pin
2 and Pin 3 both should be powered. Pin 2 is the main power to the board. Pin 3 powers a transistor switch
providing other functions and 5 VDC to the board. Provide power to either connector, the second connector can
be used as a tap to power external devices. See Appendix E for wiring examples.

One connector can be used to provide power and the second can be used as a pass through to power other
devices from the same power source.
J7 IO (Input / Output) Connections
The control board has an IO connector at location J7. The board can be configured to control measurements by
closing Input Pin1 (INPUT 1) or Pin2 (INPUT2) to Pin 6 (ground). These are normally open. When command 03 is
sent to the serial port, the measurement software will begin measurements as soon as Pin 1 and Pin 6 are
closed. See Communications Protocol appendix for further functions.
Pin 4 and 5 indicate measurements in preset tolerance or out of tolerance (Failed Part Signal). These are
normally open when measurements are in tolerance and will momentarily close after a measurement sequence
if out of tolerance measurements are recorded.
