You can only use USB keyboard if your tablet supports OTG (on-the-go) USB. With an adapter it turns your tablet into a host so you can hook up accessories. But if it doesn't support it or you are not sure, use Bluetooth wireless keyboard. A lot easier to use and their rechargeable batteries last a long time. Check my signature link, I reviewed a lot of wireless keyboards.

How can I understand if it supports OTG?

I just did a quick google of your tablet, seems to be a very old model. Looks like it doesn't support Bluetooth or OTG. Doesn't look like keyboard will be possible to connect.
