FAQ
Vtfms leftover questions
Does VTFMS send Concox 0x7878 frames?
No. VTFMS is a parenthesized ASCII CSV that starts with a 15-digit IMEI. Concox families use 0x7878 binary login.
How are VTFMS coordinates stored?
Decimal degrees when the pair sits inside plus or minus 90/180. Larger values are treated as degrees plus minutes.
Why does a VTFMS line bind without a map fix?
A void V record will not plot. An A-status record with latitude and longitude is required.
What sits after the closing parenthesis?
A 3-digit checksum. The IMEI, A/V, and lat/lon still prove the path if extras are blank.
Can a VTFMS unit run SMS setup or a controlled-action flow?
This dialect is positions only. This URL is the wire dialect, not the brand hub. There is no SMS family on this row.
