Board Check
EMP Sensor Kit

This completes the first phase of assembly. At this point, the board will be checked for proper component placement and soldering followed by an operational check prior to final assembly.

Component Check - Check components for type, location, and proper orientation. Soldering must be carefully inspected, preferably with a lit magnifier. If there are any suspicious solder connections, reflow the solder and check the result. Do this until you are satisfied that the board is OK.

  Board checked and OK

Operational Check - the following steps assume you will be using the X1W-1 or X1W-2 interface board. If you intend to use the sensor with other hardware, then you must devise a procedure to check out the board similar to what is given below.

What do I need to do this? - The following additional items are required for testing:

  Locate and attach the RCA male phono connector to one end of the coaxial cable that will be used to connect the sensor to the X1W-1 or X1W-2 'EMP Sensor' input jack.
  Tack solder the free end of the coax to the sensor board. The inner goes to the '+' and the shield to ground. Be careful not to use too much solder or heat as the coax will have to be removed and replaced with the permanent coax during installation.
  If not already done, enable the RS-232 interface on the X1W-1 by placing a jumper at "Ser". This located just the right of the RJ-11 1-Wire loop-thru jacks on the left-hand side of the board.
  Make the following connections, as required:
  • PC serial port to the X1W-1
  • If the EMP interface is on the X1W-2, connect the X1W-1 to the X1W-2 using an appropriate cable with RJ-11 modular connectors on both ends.
  • Push the RCA male connector on the prepared cable coming from the EMP sensor into the EMP interface.
  Apply power to the X1W-1.
  At the command prompt, run the 1-Wire counter utility. 
For Linux, the command is executed from the director where counter is located by typing:
./counter /dev/ttySn
where n is the serial port you are using. 
For Windows, enter
counter COMn
where n is the COM port you are using.
  While the program is running, hold the igniter within about an inch of the middle of the sensor's antenna (the copper pipe). While triggering the igniter, you should observe the counter output increasing with every trigger. If you fail to get this, shut everything down. Double-check wiring. Don't overlook a bad RJ-11 on the 1-Wire cable connnecting the X1W-1 to the X1W-2 (if you're using that mode). Be sure the X1W-1 is getting power.
  If everything worked as expected, congratulations! You have a working EMP sensor. Stop the counter program by pressing CTRL-C, remove power, disconnect all leads, and unsolder the temporary coax on the EMP sensor. Be sure to take some solder-wick and clean the holes where the coax was attached.
