Description

TMK01-M/02-M/04-M is a multi-party call intercom module. The module is mainly aimed at commercial customers. The module adopts broadband spread spectrum technology, has high receiving sensitivity, is energy-saving and environmentally friendly, and can be specially used for secondary system integration and secondary development to support all intercom functions.

The module has three working modes: intercom mode, relay mode, and intercom + relay mode. When set to intercom mode, it is only used as a full duplex intercom module; when set to relay mode, it is only used as a full duplex intercom relay. At this time, the number of channels will be halved, that is, if it is set to 8 channels, the actual work will be 4 channels; when set to intercom + relay mode, relay and intercom functions can be realized at the same time, and the number of channels will be halved at this time.

The module supports data transmission function, can send data commands in normal state and intercom state, and realize broadcast or private transmission.

The module provides two parameter control interfaces, one user parameter interface, and one developer parameter interface. The user interface is a USB interface, and the developer interface is a UART serial communication interface. Ordinary users can use the host software provided by the company to modify, read and upgrade software parameters. Developers can achieve all control functions through serial ports and obtain system working status.

The module control functions include modifying the working frequency, changing the priority, adjusting the working mode, controlling the transmitter (PPT), controlling the standby and all intercom-related operations.

The module only needs to externally connect MIC, audio amplifier and antenna to form a complete full duplex multi-party call intercom.

Features:

Full duplex, supports 8-party call at the same time, unlimited receiving

8 parties are dynamically changing. When one party exits, others can enter. 

Reserve a call position for designated personnel to ensure they can always enter

Two modes: push-to-talk intercom and VOX intercom
