4. Operation Instructions and Indicator LEDs

4.1 Driver Installation

鈿狅笍 Important: Must follow the principle of "install driver first, then plug in hardware".

1. Obtain driver compressed package PEAK-System_Driver-Setup.zip from the provided cloud drive materials
2. Extract and run PeakOemDrv.exe, accept defaults to complete installation
3. Plug device into USB interface, confirm CAN-Hardware -> PCAN-USB FD appears in "Device Manager"
4. Check adapter LED status, after driver successfully recognizes the device, refer to 4.2-Indicator LED Logic section for indicator status

4.2 Indicator LED Logic

PCAN-FD series adapters use dual-color indicators to define device status. Please first confirm your product batch, refer to your specific model:

4.2.1 Batch: 24-7 and later (Blue/Green dual-color LED)

Device Status	Terminating Resistor: Off (Default)	Terminating Resistor: On
Driver not recognized	馃數/馃煝 Blue/Green alternating flashing	馃數/馃煝 Blue/Green alternating flashing
Driver recognized, CAN off	馃數 Blue constant on	馃煝 Green constant on
Driver recognized, CAN on	馃煝 Green constant on	馃數 Blue constant on
Data transceiving (Tx/Rx)	馃煝 Green fast flash: Transmit (Tx) 馃數 Blue fast flash: Receive (Rx)	馃煝 Green fast flash: Transmit (Tx) 馃數 Blue fast flash: Receive (Rx)

4.2.2 Batch: Before 24-7 (Red/Green dual-color LED)

Device Status	Terminating Resistor: Off (Default)	Terminating Resistor: On
Driver not recognized	馃敶/馃煝 Red/Green alternating flashing	馃敶/馃煝 Red/Green alternating flashing
Driver recognized, CAN off	馃煝 Green constant on	馃敶 Red constant on
Driver recognized, CAN on	馃敶 Red constant on	馃煝 Green constant on
Data transceiving (Tx/Rx)	馃敶 Red fast flash: Transmit (Tx) 馃煝 Green fast flash: Receive (Rx)	馃敶 Red fast flash: Transmit (Tx) 馃煝 Green fast flash: Receive (Rx)

Transceiver indicator LED colors will superimpose on constant on indicator color

5. Connecting to CAN Bus

5.1 Terminating Resistor Management (Software Control)

High-speed CAN bus (ISO 11898-2) must configure 120 ohm terminating resistors at both ends of the bus. Terminating resistors prevent reflection of interference signals, ensuring normal operation of transceivers connected to CAN nodes (CAN interfaces, control devices).

PCAN-FD series supports enabling internal resistor through SysMax_PCAN_Tool, no disassembly or external connection required:

Operation Steps

1. Open SysMax_PCAN_Tool configuration tool
2. Select the corresponding hardware ID
3. Check "Enable"
4. Click "Set", observe device light feedback

鈿狅笍 Note: PCAN-FD defaults to built-in terminating resistor disabled to meet the need for direct connection to bus that already includes terminating resistor for use.

5.2 External Terminating Resistor

If you need external terminating resistor, you can contact your supplier to purchase terminating resistor accessories compatible with 9-pin D-Sub interface.
