out “deep” testing of the DMXPathfinder crosspoint electronics, the terminal
window will be faster. Both methods can be used for either test, however.
These tests require that a "loopback connector" be plugged into either the
optional insert jack on the face of the I/O module or the source/station jack at
the far end of the installed DMX wiring. Loopback connectors are standard 5-
pin XLRs with pins 2&4, and 3&5 connected. A female connector will be
required for testing the source (input) modules and wiring, while a male
connector is used to test the station (output) modules and wiring.
When a loopback test is initiated, the DMXPathfinder’s Master Control Module
generates a pseudo-DMX signal and creates a routing path through the
Pathfinder electronics according to the I/O parameters that the user has
assigned. The signal is transmitted on the selected Output Module’s send data
pair (XLR pins 2 and 3) and received back on the same module’s return data
pair (XLR pins 4 and 5). If an Input Module is being tested, the signal is
transmitted on the return data pair (XLR pins 4 and 5) and received back on
the receive data pair (XLR pins 2 and 3). Loopback Test does not check for
pin 1 continuity.

Control from the main menu. Choose the System Loopback tab. In general,
the left side of this screen is for selecting the test parameters, and the right
side is for starting the test and viewing the results. You might recognize the
green/yellow LED bar display in the center as a duplicate of what you would
see on the face of the DMXPathfinder’s Master Control and Frame Control
modules. At the top of the screen are buttons for setting manual or automatic
