Everything You Need to Know about MDC-1200

Stat-Alert, MDC-1200, and The 1,200 baud data rate utilized by MDC-1200 are additional names for the Motorola Data Communications (MDC) low-speed data two-way radio technology. Systems make advantage of the two baud rates. the space tone, which is 1,800 hertz, and the mark tone, which is 1,200 hertz. Data is sent in bursts through the radio system’s voice channel. MDC signaling has a number of features, such as selective calling, radio check, selective inhibit, unit ID, status buttons, an emergency button, and selective inhibit with radio check. These characteristics may be programmed and utilized in whatever configuration the user chooses. Typically, Motorola and other manufacturers’ high-end analog FM commercial and public safety radios include them. At least two additional businesses also provide base station decoders for the MDC-1200 that are compatible with Motorola.

Equipped with Emergency Button

The emergency button option refers to a button on handheld or in-car radios that transmits the MDC-1200 unit ID with an emergency flag attached. Although the unit ID is noted, the decoder understands this data packet as an emergency message rather than a unit ID. Optional features enable emergency messages to be transmitted over a particular channel instead than the operator-selected channel. For instance, it is possible to program a system with two channels to send all emergency messages on channel 2. This lessens the likelihood that pressing the emergency button may disrupt the main dispatch channel. When an emergency button is hit, the transmitting radio’s default configuration is for it to go absolutely quiet.

Equipped with Push-to-Talk ID

The unit ID option is used by several MDC-1200 systems. The radio delivers a data burst identifying the sending radio with each click of the speak button. Decoded into distinct four-digit hexadecimal numbers are unit IDs. Each radio would have its own four-digit unit ID, which could be broadcast either before or after a voice message. When a user pushes the radio’s push-to-talk button, the data burst is transmitted in the leading choice. The radio’s speaker can be configured to play a tone during the duration of the unit ID data. This serves as a reminder for users to speak once the data has been transmitted. Due to the header tone and the requirement to delay the data burst to provide decoders and voting comparators enough time to create an audio route to the decoder, the leading unit ID requires a little bit more air time (is longer) than a trailing ID. With the unit ID option, a default delay is specified. The transmitting of a radio’s unit ID data can be set to be delayed by up to hundreds of milliseconds within a range to account for time delay differences in each particular system. The data packet is transferred when the microphone button is released while using the trailing option. Because the audio line to the base station is already open, timing problems are avoided.
