Grove-DMX12 / DMX Simple - more than one output?

Hi,

I'm using a Grove-DMX12 with no problem.

My question: Is it possible to use more than one Grove-DMX512 at a time with an Arduino?

I have to declare the pin with

DmxSimple.usePin(3);

If I send an DMX Code, it will be send to this pin.

Is it possible to create another output pin for another Grove-DMX512, like

DmxSimple.usePin(4);

Is there any chance to address another write command?
