Dear soe min aung,
You can use a interface card like blocker to use version2 card on DM500S any firmware.
To purchase one you have to ask in the Satellite TV Equipment market such as Barr St. in downtown, Yangon.
According to one of my friend if you don't want to attach that interface card, you have to mani....te some parameters in configuration file of your cam used.
I have only tested the first option, which work fine. The second option, I haven't tested yet.
