If you are using RoviSys Turbo to share a serial connection to a CIU between CIUMon and EWS software (such as Composer or WinCAD), you can avoid changing the EWS software settings with the following strategy:

1. Move the CIU connection to a different serial port, and connect RoviSys Turbo to that serial port.
2. When you set up RoviSys Turbo to accept connections from the EWS software, connect a null cable between the serial port that the CIU was connected to and a third serial port.
3. Then, have RoviSys Turbo use the third serial port to communicate with the EWS software. The EWS software will connect to RoviSys Turbo through the null cable, using the same port as before.

A side benefit of this approach is that you can reconnect the CIU directly to the EWS simply by moving the cable back. If the computer does not have the extra serial ports you need for this approach, you can add serial ports with an internal interface card or a usb-to-serial converter.
