UMMARY
This Chapter explains how to use DMXQConnect and the DMXPathfinder’s
built-in diagnostic software to check for possible problems with file transfers or
in the DMXPathfinder modules, to assist in verifying new DMX wiring
installations and how to enter the system Access Code. It will also deal with
what corrective action can be taken by the user. For a detailed overview of the
theory of operation, functional description and troubleshooting of the
DMXPathfinder’s internal hardware and firmware systems, please refer to a
separate document, DMXPathfinder CR - Operation & Maintenance Manual.

DMXQConnect incorporates a simple user function to determine whether the
Personal Computer and DMXPathfinder are communicating properly with each
other and if all of the Pathfinder’s module frames are connected and
responding properly. If not already running, launch QConnect and click on
View, DMXPathfinder Control. Choose the Patch Rack tab. This screen
contains sixteen graphical red LEDs, each corresponding to a module frame in
the largest possible DMXPathfinder system. Click on the Retrieve
DMXPathfinder Info button, and one or more of the LEDs should turn green
according to the actual installed configuration of your system. Any LEDs that
remain red indicate missing, miswired or defective module frames as no
response was received.
The Mainframe Serial # field at upper left should now be displaying a series of
numbers that identify the first frame in the system. The System # field will also
contain some characters if a system identifying number was assigned. The
Access Code field may or may not display an 8-character user access code. If
it does, the word “VALID” will display in the Patch Rack Configuration pane to
the right. If not, “INVALID” will display. If this is the case, you will need to
contact the Factory to obtain an Access Code for your system. Refer to
Access Codes and Serial Numbers in this chapter for instructions on entering
the Access Code.

As described in Chapter 3, patch file transfers are checked on two different
levels for errors. First, a CRC (Cyclic Redundancy Check) is performed at the
