4 Description of the keyboard
The DCTEL / DCBD keyboard is designed for professional use in security and surveillance applications.
In a security system, the keyboard is used to control video switching (video matrixes), to manage alarm
conditions should they occur and for remote control of digitally controlled receivers (DCTEL keyboard).

4.2 Compatible devices for use with the DCTEL/DCBD keyboard
The DCTEL / DCBD keyboard can be used with a large number of video matrix types and digital telemetry
receivers:
•
SM42A, SM82A, SM84A, SM164A, LXRPS42A / LXRPS42TA, LXRPS82A / LXRPS82TA, LXRPS84A,
LXRPS164A
: directly connectable video matrixes.
•
SW42REM, SW82REM : video matrixes, which can be controlled by the DCFIT interface module
•
SW164OSM : video matrix which can controlled by the DCFIT interface module
For the DCTEL keyboard, it is also possible to control the following telemetry receivers:
•
DTMRX1, DTRX1 (with optional board for RS485), DTRX3, MICRODEC485 : directly controllable telemetry
receivers
• DTRXDC , telemetry receiver, which can only be controlled at a fixed rate.
See the individual instruction manuals for a complete description of the specifications of these appliances.
