MATRIX DIAGNOSTICS
The matrix STATUS led indicates system operation as follows:
Flashing Dimly The matrix is powered with at least one keyboard connected. Use 58# to display
the keyboard numbers that the matrix has detected on the BBUS.
Mainly OFF, 1 second ON The matrix is powered with no keyboards connected. – If keyboards are
connected then make sure that each keyboard address is unique between 0 – 3.
Keyboards sharing an address will cause the matrix to ignore both keyboards
with unpredictable results.
OFF Either the matrix is not powered or has an internal fault. If the power supply
seems fine then please contact technical support for further assistance.
Several commands exist that allow on site diagnostics. These commands must be entered from keyboard 1 and
display results on monitor output 1.
51# Display the matrix firmware version, number of resets and watchdog resets.
TX1500 Version shows the matrix firmware version number ie 2.3
resets shows the number of times that the system has lost power or the menu has been accessed.
watchdogs shows the number of times the matrix watchdog has reset the matrix. A high figure here can
indicate that there may be interference or power fluctuations.
55# Coaxial telemetry on.
With normal operation, the coaxial telemetry is only transmitted to a receiver whilst a camera is being
controlled. After a short period the telemetry transmission is stopped. This is prevent interference to sync
separators in DVRs etc. When trouble shooting telemetry problems the telemetry should be on all the
time so the 55# command would be used and then the receiver CABLE and ERROR leds inspected.
Pressing # again will stop the telemetry transmission.
56# Display the status of matrix switch SW1, the display shows a HEX number which corresponds to the
switch settings for SW1. The number is displayed whilst the # key is pressed. Releasing the # key will
clear the number from the screen.
Number displayed SW1 switch
0 1 - 6 OFF
1 1 ON
2 2 ON
4 3 ON
8 4 ON
10 5 ON
20 6 ON
When more than 1 switch is ON then the number displayed will the sum of the values of all switches that
are ON, ie. 1,2 ON, display shows 03, 1,2,3,4 ON displays 0F
RS485 telemetry directly from the TELEMETRY port and should not normally be selected.
Example numbers that could be displayed
0 = normal mode
1 = DIXONS mode – This is a special mode developed for DSG driving Mark Mercer
57# Display the status of matrix switch SW2 as per 56#.
2A = SW2-2/4/6 ON = FACTORY INITIALISATION on a power up. This is used to clear any
programming and load default values. Useful if the matrix has had a corrupted programming. Once
powered up turn all SW2 switches OFF again to prevent further accidental initialisations.
58# Display number of keyboards or BBUS/I-F with addresses connected to the matrix along with the
software version of each keyboard or BBUS/I-F.
