JKBMS USB-RS485-RJ45 Converter Cable for Smart BMS Communication

JKBMS USB-RS485-RJ45 Converter Cable for PB Series

Connect a compatible JKBMS PB-series Inverter BMS to a PC using the RS485 port on its interface board. Use the matching JKBMS PC software and follow the manual for your exact BMS model and hardware version.

Compatibility and Connection

• PB series: use this USB-RS485-RJ45 cable with the RS485 port on the PB interface board. Check the connector and pinout against the matching manual before connecting.
• B/BD series: compatible B/BD models with a GPS port use the appropriate USB-TTL cable connected to the GPS port for PC communication. This USB-RS485-RJ45 cable is not a substitute for that connection.
• PD series without a GPS port: USB-TTL PC connection is not supported. Contact JKBMS Support with your exact model before ordering any PC cable.
• A BMS having an RS485 or CAN interface does not by itself confirm compatibility with this cable for PC communication.

PC Software and Firmware

Use software and any required driver matched to your cable and BMS. Only attempt a firmware update when the instructions explicitly support your exact model and hardware version; do not use firmware intended for another version.

Package Contents
