the Frame or Master Control Module, and problems that affect every line in the
system are most likely caused by a I/O bus cable connection. Make a note of
the defective I/O channel and which lines are affected, then refer to the
DMXPathfinder CR – Operation & Maintenance Manual for further assistance
in correcting the fault.

Launch DMXQConnect and select View, DMXPathfinder Control from the
main menu. The Terminal window is open in the foreground. Click on the
Connect button below the window, and several lines of text will appear. Your
personal computer is now in direct text-mode "conversation" with the
DMXPathfinder. The heading will read “DMX Crosspoint Router Ver.2.0
Diagnostics” or something similar depending on the vintage of the Pathfinder
firmware. Below the heading is a list of single-letter keyboard commands for
various functions. Three menu choices are listed: System Loopback Test,
Access Code Input, and Serial Number and Access Code Support Status. Use
upper-case characters to select from these items.
Choose L for Loopback Test. Notice that the window now lists a menu
consisting of single-keystroke commands with short form descriptions, and at
the bottom there is a response area with a set of headings. The response
section provides an indication of the currently selected hardware I/O device
channel and the status of the test (Passed or Failed).
The following is a detailed explanation of the use of the Loopback Test terminal
command menu to test the DMXPathfinder electronics. Note that the response
area updates each time a command is given at the keyboard, and that
commands may be in upper or lower case characters.
f - Single/multiframe system select
Pressing "f" toggles the selected system configuration between single
frame or multiple frame systems. A single-frame system is the smallest
possible configuration, with all Input and Output modules in the same
frame. Most systems are multi-frame, that is, where Input Modules are
in the first rack frame and Output Modules are in one or more
subsequent frames. This setting must match the installed Pathfinder
hardware for the tests to work properly.
t - Input/output card type select
Pressing "t" toggles the I/O module type between Input and Output,
allowing the user to select the type of module to be tested.
m - Manual/automatic mode
