RED-EVF Interface 
The RED-EVF interface is a custom digital video and power interconnection between the camera 
and a RED-EVF. Due to the data integrity nature of this interface, the pin-out is not published.  
Contact RED technical support for details of available RED-EVF cable lengths. 
RED-LCD Interface 
The RED-LCD interface is a custom digital video and power interconnection between the camera 
and a RED-LCD. Due to the data integrity nature of this interface, the pin-out is not published.  
Contact RED technical support for details of available RED-EVF cable lengths. 
Note: The Aux 232, RED-EVF and RED-LCD connectors use the same shell size. Do not at-
tempt to force fit a 10-pin Aux 232 cable into a 16-pin RED-EVF or RED-LCD connector, or 
force fit a 16-pin RED-EVF or RED-LCD cable into a 10-pin Aux/RS232 connector. 
Line Level and Microphone Level Audio Inputs 
A three-pin mini-XLR connector is provided for each of the camera’s Line / Microphone inputs. 
Audio is recorded at 24-bit 48KHz, which provides high audio fidelity and wide dynamic range. 
The Line Level and Microphone Level analog audio input signals are routed via a high quality 
A/D and pre-amplifier, whose gain stage may be controlled using the Input Level control to 
achieve the desired audio reference / recording level.
