1 Module Description

The coder board CMB-1 is used as a central logic board for ABITRON radio remote control transmitters, which

evaluates digital and proportional controls and transmits them as a digital data telegram via the integrated RF-

part or cable control to a suitable MBT-1 receiving module as well receiving and evaluating feedback data

telegrams from the MBT-1.

The integrated RF-part of the CMB-1 is designed as a multiband transceiver, which allows, depending on the

hardware version, different SubGHz frequencies and additionally 2.4GHz. Simultaneous use of SubGHz and

2.4GHz is not possible.

The frequency can be set with reference to the applicable country regulations, legal provisions and approvals,

using an ABITRON configuration tool.

The coder board CMB-1 contains all necessary function blocks, interfaces and signaling devices that are required

for the operation of the transmitter. Additional external modules can be optionally connected and controlled

via the integrated interfaces.

Following function blocks are integrated on the coder board CMB-1:

• Buzzer as an acoustical signal generator

• Bidirectional RF-part with adjustable GHz and Sub-GHz frequency ranges

• 24 configurable inputs or outputs for digital commands

• 8 configurable analogue or digital inputs

• Plug in location for operating LEDs

• Plug in location for optional external buzzer

• Plug in location for TTL in

• Plug in location for TTL out

• SPI interface for optional MEMO or optionally usable for 4 additional digital inputs or outputs

• I²C interface for optional extension boards

• B2B interface for optional extension boards (only for CEB extension boards)

• micro USB interface used as e.g. configuration interface (conducted parallel to the B2B interface)

• Cable control interface

• Interface for stop switch
