We have received many requests for our products to be connected wirelessly. So we developed a simple solution to replace cables from our triggers (PunchLight Midi, GPI, DLi or Relay Switch Box USB) that go to external lights. The PunchLight Wireless Upgrade Kit consists of two small boxes. The first is a transmitter, connected to one of the trigger units via a 12V out. The second unit is a receiver, a small box which has one output and a connector for an external PSU. You can connect any of the PunchLight external lights to the receiver.
