| I’m setting up a Bluetooth communication from my computer to a RS485 Bluetooth device that is connected to a PTZ camera with RS485 2 wire connection. My problem is that the camera control software is based on RS232 (Pelco D) control protocol and the software requires a RS232 to RS485 converter attached to the computer to work with RS485. So with the Bluetooth (wirelesss) connection I need to convert the RS232 to RS485 before sending control signals from my computers Bluetooth virtual Serial port to the remote Bluetooth device. Does anyone know of a ‘virtual serial port’ converter that can convert the RS232 input to RS485 output? |

| I've never heard of a virtual RS232 to RS485 COM driver, ..don't think it exists. Couldn't you convert the RS485 to RS232 at the camera end instead? |

| Thanks for the reply. That’s about what it’s come down to. I’m actually swapping out the RS-485 Bluetooth module for a RS-232 module and will convert it to RS-485 (the camera control protocol) at the camera end. |

| A RS232 to RS485 converter works fine in combination with for example a RS232 Bluetooth adapter. Wouldn't that solve you problem? if I understand you correctly.. |
