FAQ
Ramac leftover questions
Does Ramac send Concox 0x7878 frames?
No. Ramac posts a JSON object with DeviceId, PacketType, SeqNumber, and UpdateDate.
What reply does a known Ramac unit get?
The body {"CaseID":1,"EventID":1}. An unknown DeviceId is answered HTTP 400.
Why does a Ramac POST bind without a map fix?
Latitude and Longitude must both be present. A body that omits either reuses the last known point.
How is Ramac time parsed?
UpdateDate is yyyy-MM-dd HH:mm:ss and becomes device time. LocationDateTime in the same shape overrides fix time when present.
Can a Ramac unit run SMS setup or a controlled-action flow?
This dialect is positions only. Alert, GpsEvent, BatteryPercentage, Battery, and DeviceTypeText are extras. There is no SMS family on this row.
