Note: This protocol is the same as PELCO-D, which is used to control a speed dome. So, if
you use PELCO-D to control a speed dome with your keyboard, you can also use the
keyboard to control the DVR through this protocol using a different address to distinguish the
DVR and the speed dome.

you push the call button on the keypad, then enter the number according to the
Var table
above, then push the enter button.
