DMR transceivers must be programmed with repeater frequencies, talk groups and time slots, receive and scan groups etc which is contained within a configuration file, commonly known as a "code plug". Programming cables and software are generally available from the DMR transceiver manufactures.
Writing a configuration file from scratch can be a challenging experience for a newcomer to DMR, hence The St George Amateur Radio Society (SGARS) has setup a database of DMR configuration files provided by SGARS members. These code plugs include configuration data for DMR repeaters in the Sydney, NSW and ACT area. DMR configuration files can be downloaded from here.
Disclaimer: DMR transceiver configuration files are provided by The St George Amateur Radio Society (SGARS) and it's members in good faith, however SGARS and it's members do not accept an responsibility for the configuration data contained in the file.
To access the DMR network each amateur radio operator must have an unique user ID, which must be included in the configuration file. DMR user ID numbers are managed centrally, and may be obtained here.
