2.3 Data Service
DMR data services include text message, GPS, supplement services, etc. In this
chapter, we mainly introduce text message and GPS services.
2.3.1 Text Message
With DMR technology, you can send, receive, forward and save text messages
using your radio. For your convenience, you can preset the regular text messages
and save them in the radio in advance. Then you can send a preset message
directly or after you edit it. In the radio with display, you can enter any text message
via the keypad, save it in the radio and send it. As for the radio without display, you
can only preset the message via the CPS, and send it by the programmed key.
However, you are not able to check or edit it through the radio. You can use a
Hytera DMR radio to send text message to an individual user, a group or the control
station, and reply or forward the message to other radios.
Text messages are applied in:
ˆ Communication of sensitive information;
ˆ Noisy environment where it is hard to hear the voice clearly;
ˆ The radio with problem in voice services.
Text message include two categories: private message and group message.
ˆ Private message: text message sent between two radios.
ˆ Group message: text message sent by a radio to a group of radios. The group
message differs from the private message in that it is a point-to-many service
without acknowledge.
Parameter configuration
The same as private call, text message needs such parameter configurations: ID,
color code, frequency and slot, and it is subject to Tx Admit.
As private message is sent between two radios, it does not involve a third party ID.
Both parties must be in the same slot on the same channel and have the consistent
Tx and Rx frequency and color code.
To send private message, you need to set the ID first. You may search for the
receiver by the ID or the alias.
