ETVision
Controller
The
ETVision
Controller connects to the
ETVision
Wearable Optics with the HDMI cable extending
from the wearable optics frame. Besides the type A HDMI port, the Controller has a micro SD card
slot, a phono jack, a LAN port, a power supply connector, a power button and power LED, and a
record button and record LED. Both LEDs have multiple colors to indicate various possible states as
described in Appendix A (section8.1) of this manual.
The HDMI port accepts the type A HDMI connector from the ETVision Optics cable. A set screw on
the bottom of the Controller, directly under the HDMI port is used to secure the HDMI cable
connector after insertion.
The Controller can be connected to the
ETVision
Laptop using the LAN port and standard LAN cable,
or via Wifi. Alternately, the Controller can record video and audio data directly to a micro SD card.
If the Controller is connected to the
ETVison
Laptop, either with a LAN cable or Wifi, audio from the
microphone on the optics frame is transmitted to the
application on the Laptop, and audio from the
Laptop microphone is transmitted to the phono jack on the Controller. If headphones or earbuds are
connected to the Controller phono jack and worn by the participant, this enables two way
communication with someone near the laptop.
