JKBMS USB-TTL-1M Cable for Smart BMS PC Communication

JKBMS USB-TTL-1M Cable for Smart BMS PC Communication

The JKBMS USB-TTL cable is for PC communication with compatible JKBMS B/BD Smart BMS models equipped with the required GPS port. Compatibility must be checked by exact model and hardware interfaces, not by the B/BD family name alone.

Compatibility — Check Before Ordering

• Compatible B/BD models: use the matching USB-TTL connection at the protection board's GPS port. Check the model-specific manual for the required CAN/RS485 and GPS connection arrangement, connector and pinout before connecting.
• All PD-series models: not compatible with this USB-TTL cable, because PD boards have no GPS port. This applies to every JK-BD6A20S…PD and JK-BD6A24S…PD model, including 4PD, 6PD, 8PD, 10PD, 12PD, 15PD and 20PD.
• PB-series Inverter BMS: not compatible. Use the matching USB-RS485-RJ45 cable at the RS485 port on the PB interface board instead.
• Do not assume a CAN/RS485 connector accepts USB-TTL directly. Follow the exact model's connection instructions.

PC Software

Use the matching JKBMS PC software for supported monitoring and parameter configuration. Check the driver requirements for your cable. Firmware updates are only supported where the instructions explicitly cover your exact BMS model and hardware version; never use firmware intended for another version.
