DMR Message Format
The WT Protocol can be used for sending DMR tier 1 messages. The protocol allows for an ID
(group or individual), colour code, radio type and message to be specified.
Different DMR Radio manufacturers frequently have differing DMR implementations that
often allows only same brand to same brand communication.
The WT protocol uses the commonly used “baud” field to set the DMR radio type. Sending a
DMR message to an incorrect radio type may result in the radio not receiving messages, or the
message being corrupted. Ensure that the group ID used is common to all same brand radios.
Basic Format:
WT1234567D6 x TEST\r
Where all fields are previously defined, but ‘ x ’ is now a DMR “Type”.
Type ‘0’ – This is a short message type, often used by Hytera.
Type ‘1’ – This is a short message type, often used by Kirisun.
Type ‘2’ – This is a compressed UDP type, often used by Hytera and Motorola.
Motorola Radio Usage:
No messages are transmitted using any Motorola format. Motorola radios must be configured
as follows:
• Compressed UDP Data Header: DMR Standard
• Text Message Type: DMR Standard
Example:
To send a DMR message to group ID 1001, colour code 6 with payload of “TEST MESSAGE”
and to a type ‘0’ radio (Hytera)
WT0001001D6 0 <SPACE>TEST MESSAGE<CR>
Example:
To send a DMR message to individual ID 104, colour code 6 with payload of “TEST
MESSAGE” and to a type ‘0’ radio (Hytera)
WT00001041d6 0 <SPACE>TEST MESSAGE<CR>
TReX DMR ID
Messages transmitted will have the TReX serial number as the source. If the TReX unit ID is
configured to a numeric value greater than 1, then this becomes the transmitted source ID.
