Iím 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 Ďvirtual serial portí 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. Thatís about what itís come down to. Iím 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..
