Telemetry & communication unit

COP921’s ability to send callout text messages in addition to TMS messages is ideal for sending alerts to a group of up to eight subscribers.


The COP921 is a telemetry and communication unit that allows up to eight radio users to automatically receive a text message. COP921 supports two types of text messages: TMS (Text Messaging System) which can be received by each MOTOTRBO device, and CallOut text messages which can be received by MOTOTRBO radio devices with a built-in Option Board DMR910.

The CallOut text message is displayed on the radio device until a key is pressed by the operator. Simultaneously, different tones with variable volume levels may be generated via the loudspeaker. The way of representing the CallOut text message is not programmed in the radio device but is encrypted in the CallOut text message (the way the message is represented is defined within the COP921). It is also possible to delete the CallOut text message from the radio device via the air interface, which is of value when, for example, a defect has been rectified before the radio subscriber has pressed a key. For instance, when a group of radio subscribers is alerted and one of the subscribers accepts the service order, the CallOut text message can be deleted from all other radio devices.
