A true wireless solution! The ADJ WiFLY EXR Battery is a battery powered wireless DMX transceiver (transmitter/receiver in one) that is compatible with all ADJ WiFLY “EXR” products. After connecting the WiFLY EXR Battery transceiver to a DMX Controller users can send a constant and reliable wireless DMX signal up to 2500 feet to other ADJ WiFLY “EXR” products. This transceiver is backwards compatible with ADJ WiFLY products, however, it will only transmit up to 2500 feet with other “EXR” Extend Range products.
