You want to copy the firmware or the channel list or both from 1 box to a different box? Have you got the down tool (loader)? Not really sure what you want to do mate, can you clarify please?
You can do it by connecting the 2 with a rs232 cable and then go into to main box and select data download under the installation menu this will give you the option of sending the firmware or the channel data so select which one you want and then point the remote at the second box and press the red button twice and then the red power button
Just make sure that the boxes are facing away from each other and you are quite close to the box when using the remote coz you could interfere with the main box when trying to do it
