REMEDY
• Make sure the jack from the power supply is properly
inserted in its socket.
• Make sure the power supply is properly inserted in the
main outlet socket.
• Make sure that, after the matrix opening, the LED
wiring connector was not disconnected.
• Make sure the matrix has the same communication
protocol as the keyboard (see configuration dip
switches in section 3.4.2.2).
• Make sure the communication rate is the same as the
setting for the keyboards (see configuration dip
switches).
• Make sure the cables are intact and follow the wiring
diagrams (see the chapter on installation). Do not
exceed the maximum allowed distances: 1200 m for
non-remote powered keyboards (RS485 lines A and
B) and 700 m for remote powered keyboards (12VDC
Lines and GND).
• Output 4 has been set for control by VCR trigger. If it is
to be controlled by the keyboard go to the 'External
triggers' item and set Use VCR: No.
• Some keyboard models (MTC-1), allow the control of
some output videos to be disabled. See the specific
keyboard manual and check the settings for the output
videos that can be controlled by the keyboard.
• In the menu for the Aux line, make sure protocol and
baud rate settings for the line are the same as those
for the receiver/mux to be controlled
• The matrix and hence all the keyboards should have
the MACRO protocol setting and the same baud rate
• Check the wiring for the Aux line with that shown in the
installation chapter.
• Check the menu for enabling Coax Telemetry
Transmission via coaxial cable.
• The matrix and keyboards should have the MACRO
protocol setting with the same baud rate
• The receiver address should be the same as that of
the input video to which it is connected by coaxial
cable (e.g. input video 4 / receiver with address 4 )
• Make sure the coaxial cable is intact. Do not insert
video distributor, amplifiers or equalisers between the
telemetry receiver and matrix input. Do not exceed the
maximum allowed distance for telemetry transmission
via coaxial cable (350 m)
• Use the menu to make sure the switching sequences
have been set up with the input videos present.
• If manual switching is carried out on an input video that
is not present, a completely black screen without
identification text will be shown.
