This Sync Cable is for connecting the Skyport Universal Receiver (and other brands) to Elinchrom units that use the 3.5mm Mini Plug socket. It is Mini Plug to Mini Plug (3.5mm) and measures roughly 15.75" (40cm) long.
This module fits only to Elinchrom units such as the Digital RX series, the Ranger RX series and the Style RX series. No extra battery is required for the transceiver to be ready to use. For the Ranger RX series, the ELS Transceiver RX Adapter is required.
