RS485 to Ethernet Converter (BF430)
Visit the online store page
Current manufacturer information: Chiyu model BF-430
EG4xxx (Pro and Core) are recommended to utilize the eGauge USB485 (serial to USB) adapter instead if possible.
Power can be provided (9-30V) to either terminals or barrel jack plug. eGauge sells a compatible 12Vdc power supply.
The Chiyu BF-430 is an RS-485/RS-232 to Ethernet converter. It is required for serial communication to third-party devices (for example, Modbus RTU) on older eGauge models without USB ports or to communicate over a network rather than serial line directly to the eGauge.
