Elinchrom Skyport Transceiver RX Speed. This module fits only Elinchrom RX units, using the integrated multiple interface for triggering and for the remote computer operating option. No internal battery is required, just plug into a Style RX, Digital RX or Ranger RX flash unit (Please remember to double check the “Group” and “Channel Frequency” settings) and the Transceiver RX is ready to use. To control flash power, modelling lamp on/off and flash synchronisation, requires only the Transmitter Speed. To control all RX functions, the latest EL-Skyport software and the USB RX Speed module is required. The EL-Skyport software also offers additional features, such as the programmable “Flash Delay”, Flash-Counter and other control features that will be added as future software upgrades.
