== Troubleshooting Guide ==
=== Not Reading Instrument ===
# Using Audina cables (or Unitron cables)?  
  * Only Audina (or Unitron) cables should be used.  For the Nueve product, only the Nueve cables from Audina should be used.
# Using CS54 flexstrips? 
  * Only CS54 flexstrips are supported.  These are about 1 inch long, and have 4 gold contacts.
# Using HiPro? 
  * Reset Hi-Pro: Disconnect the Hi-Pro power cable for 5 seconds.  Alternatively, perform a Hi-Pro Update (in ezFIT: Tools > Hi-Pro Update).
# Using correct programming box settings?
  * Check that the software is configured correctly under Tools > Options > Fitting (tab) > Programming Box
# Using battery in instrument?
  * Remove it.  It helps to determine if power is coming from the programming box and that there is good connectivity.  The instrument should whistle when put inside your hand.
# Using correct software version?
  * Check the [[ezfit:Software Requirement Matrix for Products]] for the instrument you are trying to read.

=== Error Communicating with Device Hi-Pro ===
# Using correct COM port?
  # The port must be between COM1 - COM4 for the Hi-Pro to work. COM5 and up are unusable.
  # See Control Panel > System > Device Manager > Ports (COM & LPT).  
  # Select the Hi-Pro or adapter device and go to Port Settings > Advanced > COM Port Number to change it (must not be in use).
  # If multiple COM ports are in use but there is only one COM device listed under Ports (COM & LPT) follow the steps below.
    * Follow step 3 above for each port listed in use.
    * Finally set the COM port back to COM1.
    * Reboot the computer.
    * Perform a Hi-Pro test.
# Using correct Hi-Pro drivers?
  * Reinstall ezFIT, and select the correct Hi-Pro drivers (most likely "Hi-Pro Classic").  
  * If selecting Hi-Pro USB, then verify that the Hi-Pro USB drivers (shipped with the programming box, or in the ezFIT installation CD-ROM) are also installed.
  * Restart the computer.
# Run the Hi-Pro test.
  * In ezFIT 4 go to Tools>Hi-Pro Test.
  * In ezFIT 2012 click Tools, make sure the programming box is Hi-Pro and click the Test button.
  * The Hi-Pro test should manually be run as administrator in the following case.
    * The Hi-Pro test indicated the Hi-Pro was found.
    * You've closed and re-opened ezFIT.
    * When you try to detect the Hi-PRO activity lights are inactive.
=== Installing USB-Serial Adapter ===
# Installed USB-Serial adapter drivers?
  * Adapter drivers must be installed before connecting adapter to the computer.  See the CDROM that came with the adapter package, or search for the drivers on the Internet.
  * For devices where the manufacturer is unknown see [[ezfit:Troubleshooting Guide#Unknown Devices]].
# Connected adapter?
# Using correct serial port?
  * The port must be between COM1 - COM4 only for the Hi-Pro to work. 
  * See Control Panel > System > Device Manager > Port (COM & LPT).  
  * Select the device and go to Port Settings > Advanced > COM Port Number to change it (must not be in use).

=== Unknown Devices ===
# Double click on the device.
# In the details tab look at the 'Hardware IDs' property.
# Make a note of the Hex numbers. These will be your vendor id and product/device id. (note: These may be listed as VID, VEN, PID or DEV)
# Do a search on http://www.pcidatabase.com/ for your device id and find the vendor in the list that comes up.
  * If the device id gives no results try the vendor id so you can at least try to find a website for more information.
