If you have an Openbox / Skybox S9 / S10 / S11 receiver ... there is a method of identifying the original or clone.

Complete the following steps:

1) back up your tuner (USB or RS232)
2) install the firmware from June 17, 2011 or the latest
3) go to Menu ---> Tool ---> Information ---> Press "8888" and you will see CHIP iD.
If your CHIP iD is one of the following list (the list is updated continuously), you have the so-called original tuner.
