DMO has special rules regarding timestamps and how often Transmitter PDUs should be published to the network. DMO uses an Absolute Timestamp instead of a Relative timestamp. In order to change it, add the following line to the [general] section of the DIS gateway:

timestamp = absolute

To change the Transmitter PDU publishing rates edit the parameters.ini file, located in the the Domain of a Project. You must use the file browser on the left of your Project in ACE Studio in order to access the parameters.ini file. The following lines can be edited to change when a radio sends a Tx PDU to the network:

[general]
; meters
moving_threshold = 500

; milliseconds
moving_timeout = 2000
normal_timeout = 5000
