and custom frame lengths
– Classic and Extended checksum formats
– Configurable transmit messages, single shot or periodic
0.2.3 Logging
• Extractable industry grade micro SD-card (8-32GB)
• Standard FAT file system (can be read directly by a PC)
• Logging to industry standard .MF4 (ASAM MDF4) file format
• Simultaneous logging from 2 x CAN-bus + 2 x LIN-bus
• Message time stamping with 50 us resolution
• Supports cyclic logging mode (oldest log file is deleted when memory is full)
• Log file splitting based on file size or time
• Session number (power cycle) log file naming (groups log files)
• Globally unique ID for each device ensures unique log file naming
• Power safe (device can be disconnected during logging without corrupting data)
• High-performance logging

0.2.4 Real-time clock (RTC)
• High precision real-time clock retains date and time when device is off
• For WiFi-enabled devices, the real-time clock can be synced with an NTP time server
0.2.5 Electrical
• Device supply
– Channel 1 voltage supply range: +7.0V to +32V DC
7
– Reverse voltage protection
8
– Transient voltage event protection on supply lines
9
– Consumption:
∗ CANedge1: 0.8W
∗ CANedge2: 1W
• Secondary port output supply
10
– Configurable output supply on connector 2 (CH2), fixed 5V up to 1.5A
11
– Supports power out scheduling to control the output state based on time of day
5
Data lengths are defined by bits 4 and 5 of the LIN identifier
6
See the performance tests
7
The device is supplied from connector 1 (CH1)
8
Up to 24V
9
The transient voltage protection is designed to clamp low energy voltage events. High energy voltage events may
overheat and destroy the input protection
10
Can be used to supply external devices
11
The 5V output can be used to power WiFi hotspots, sensors, small actuators, external LEDs, etc.
