8 Maintenance
The DCTEL / DCBD keyboard does not require any particular maintenance.
We recommend installing it so that the power supply and connecting cable are positioned in such a way that
they do not get in the way of the operator.
9 Troubleshooting
The great advantage of the DCTEL / DCBD keyboard is that it is very easy to use. Nevertheless,
problems may sometimes arise during installation, configuration or use.
PROBLEM PROBABLE CAUSE REMEDY
The Power supply LED is off
and no other LED is on No power supply Make sure the power supply jack is
inserted correctly.
If necessary, when receiving remote
power from the matrix, check the
connections in the Video line.

Incorrect or faulty Video line
wiring. Make sure the matrix and keyboard have
the same type of protocol setting
(MACRO if the telemetry is to be
transmitted via coaxial cable) and the
same baud rate.
Check the video line wiring.
The telemetry commands are
not carried out (DCTEL
keyboard) Keyboard configuration error
LED’s of numeric keys all off

1/8, 9/16 to be certain the correct
address has been chosen for the
receiver to be controlled
The telemetry command via
coaxial cable is not carried out
(DCTEL keyboard) Video line setting error If the LED corresponding to the active
monitor flashes, there is probably a
communication error with the matrix.
Make sure both the matrix and keyboard
have the MACRO protocol setting, and
the same baud rate. Check the wiring.
During On Screen Menu
