MATRIX 300N™ REFERENCE MANUAL 
 
9  TROUBLESHOOTING 
 
 
9.1  GENERAL GUIDELINES 
 
  When  wiring  the  device,  pay  careful  attention  to  the  signal  name  (acronym)  on  the 
CBX100/500 spring clamp connectors (chp. 4). If you are connecting directly to the Matrix 
300N M12 17-pin connector pay attention to the pin number of the signals (Appendix A). 
  If you need information about a certain reader parameter you can refer to the DL.CODE 
help on line. Connect the device and click on the link to the parameter you’re interested in. 
  If you’re unable to fix the problem and you’re going to contact your local Datalogic office or 
Datalogic Partner or ARC, we suggest providing (if possible): Application Program version, 
Parameter Configuration file, Serial Number and Order Number of your reader. You can 
get most of this information while DL.CODE is connected to the reader. 
 
DL.CODE Installation: 
Autorun  or  Start.hta  doesn’t 
run 
  Check Windows settings to see if Autorun is disabled. 
  Associate  the  file  type  .hta  with  the  Microsoft  HTML 
Application host mshta.exe in Windows\System32. 
Power ON: 
the “POWER” LED is not lit. 
  Is power connected? 
  If using a power adapter (like PG6000), is it connected 
to wall outlet? 
  If using rail power, does rail have power? 
  If  using  CBX,  does  it  have  power  (check  switch  and 
LED)? 
  Check if you are referring to the M12 17-pin connector 
or to the CBX spring clamp connectors. 
  Measure  Voltage  either  at  pin  1  and  pin  2 (for  17-pin 
connector) or at spring clamp Vdc and GND (for CBX). 
One  Shot  or  Phase  Mode 
using  the  Input  1  (External 
Trigger) or Input 2: 
the  ”TRIGGER”  LED  is  not 
blinking  while  the  External 
Trigger is switching. 
 
  Check if you are referring to the 17-pin connector or to 
the CBX spring clamp connectors. 
  Is the sensor connected to the Input 1 or Input 2? 
  Is power supplied to the photo sensor? 
  For NPN configuration, is power supplied to one of the 
two I1 or I2 signals (A or B)? 
  For PNP configuration, is one of the two I1 or I2 signals 
grounded (A or B)? 
  Are the photo sensor LEDS (if any) working correctly? 
  Is the sensor/reflector system aligned (if present)? 
  On the Reading Phase step check the Input 1 or Input 2 
Debouncing Time parameter setting. 
  On  the  Reading  Phase  step  check  the  settings  for 
Acquisition  Trigger,  Reading  Phase-ON,  and 
Reading Phase-OFF parameters.
