Frame type

Frame identifier in base

Frame payload data (hex-only, ignoring spaces, commas and '0x' prefixes)

RTR frame Data Length Code (DLC) ⓘ

CAN bitrate ⓘ

Whole frame

Whole frame without stuff bits
Whole frame with stuff bits (as appears on the bus)
Worst-case frame length after stuffing (assuming same ID and payload lengths) ⓘ
Whole frame transfer time (including stuff bits) ⓘ
Overhead (including stuff bits) ⓘ
Effective bitrate to transfer the data (including stuff bits) ⓘ
