1. Off-line recording: no need to connect to computer, direct power supply can record all the data of CAN bus. 2. TF card storage: standard 32G high-speed TF card, can store 350 million frames of CAN data. 3. All kinds of CAN lines: support High-speed / low-speed / fault-tolerant / single-line CAN / comfort / entertainment CAN lines. 4. Off-line playback: the saved data can be sent back to the CAN bus directly as is, simulating the device to send signals. 5. Off-line relay: between CAN1 and CAN2, it can relay intelligently and forward directly or rewrite and forward. USB power supply: 5V power supply through USB cable, can be connected to cell phone charger/computer. DC power supply: 9V-35V wide range power supply, 0.5A. Built-in clock: It can save the received Beijing time for each frame of data. Data saving format: , csv, , CAN. Interface: POWER: power switch, mainly for battery power. S1-S10: Baud rate and function selection switch. USB: can configure Beijing time/copy TF card data through PC (USB port can't read CAN data in real time). TF Card: standard TF card. LED 1-8: LED indicator. +PE-: Switching power input. 1H/1G/1L: CAN1 channel, high-speed CAN, baud rate 10k-1M. 2H/2G/2L: CAN2 channel, high speed CAN, baud rate 10k-1M. 3H/3G/3L: CAN3 channel, low-speed fault-tolerant CAN, baud rate 10k-125K (Note: CAN3 channel is the extension channel of CAN2 channel, CAN2 channel is when CAN3 channel is enabled). CAN1 120R: CAN1 channel terminal resistance selection switch. CAN2 120R: CAN2 channel terminal resistance selector switch. The printed words from batch to batch, but not affect the use.
