# Configuring Software for VTR Emulation

Once your hardware is configured for VTR emulation, uncomment the Emulator keywords in the software initialisation configuration file that correspond to the emulators that you want to enable.

To uncomment the appropriate Emulator keywords:

1. Log in to Smoke.
2. In a Linux terminal, type dlcfg to open the software initialisation configuration file in a text editor.
3. Scroll down to the EMULATOR KEYWORD section, and then remove the pound (#) sign to uncomment the entries that correspond to the emulation modes you want to work with.
   NoteYou can perform video I/O using multiple video standards per session. To do so, you can uncomment emulators corresponding to different video timing values. Once in a project, you will be able to change the video timing without exiting your session.
4. If necessary, edit the serial port definition in each line (/dev/tty4d<port#>) to make sure it corresponds to the serial port that you want to use for RS-422 remote control of the VTR emulator.
5. Save the file and exit the text editor.

   You are now ready to start the application and enable an emulator.
