To connect your tracker using the ERM protocol, you need to have a erm channel created first.

Point your tracker to the channel's domain name:port via SMS or configuration tool provided by the vendor.

Then create a device instance for your tracker and use a 15-character IMEI (usually specified on the tracker casing) in the ident field.

Use the Toolbox tab on the device screen to check if the messages are coming.

Parsing note: to make sure Starlink messages are parsed correctly, the fields in the dynamic event structure (parameter 0177) should be separated by commas, e.g. #EDT#,#EID#,#PDT#,#LAT#,#LONG#,#SPD#,#HEAD#,#ODO#,#LAC#,#CID#,#VIN#,#VBAT#.
