I'm using a handful of the ADJ wifly EXR battery in my lighting rig for an upcoming show. I have been been using one tranceiver to connect to my lighting board and send the DMX signal to other tranceivers in the rig that are connected to some specialty lighting for effects. I have noticed that after a little while it appears that the tranceiver I am using to send the signal to the others no longer is sending a signal and the tranceivers in the rig show there is no wifly channel present. All tranceivers are set to the same wifly channel. I'm getting concerned that if I turn on all my tranceivers at the start of my show, that I will not make it through my 2.5 hour musical without losing the connection and not being able to control my special effect lighting. Any insight our guidance would be greatly apprecaited.
