Review: Plug and Play - Das Kabel funktioniert Tadellos an meiner Liontron LX48-100 Speicherbatterie um auf das BMS zuzugreifen. Wurde auch am Computer sofort erkannt Plug and Play Review: Works as advertised - I bought this to reset the admin password and the networking on an APC 7932 PDU. The USB-to-RJ12 showed up as a COM port on my laptop. Although I did have to go and download/install the drivers for it myself, it worked like a charm. I'm very pleased with the results. ## Features - DSD TECH: DSD TECH focuses on the development of communication connection devices such as USB/Serial/Wireless.

The driver interface of this chip does follow the RS232 Protocol however, the voltage read out is limited to +5V if your device uses true RS232 wiring then this device will not work. True RS232 wiring has a reversed(voltage shift) voltage that ranges from -15v to +15v (3V min register). In short, unless your device only needs RXD/TXD/GRD within 0 to +5V don't expect it to work. **Q: Will this cable allow me to connect a headset with mic (Plantronics CO52) to my computer to?** A: no, it is a usb to RS232 serial adapter with rj12 interface. It only applies to data communication. Not used for audio transmission. **Q: the title is labelled as 6p4c is it not 6p6c rj-12?** A: We confirm that this is the RJ12 interface cable. The RJ12 interface corresponds to a 6-core cable. But we only used 4 touch points of RJ12 interface . So that it can be compatible with 6P4C **Q: Does this cable create a virtual COM port?** A: Yes, Built-in FTDI FT232 chip. When you install the driver, a virtual serial COM port is created. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Plug and Play *by K***F on 26 June 2025* Das Kabel funktioniert Tadellos an meiner Liontron LX48-100 Speicherbatterie um auf das BMS zuzugreifen.
