Caption Assist
Overview
Introduction
The Caption Assist (CA C3) is a professional, hardware-based live captioning system. During a video call or other
live event, the Caption Assist can use the power of the Google Cloud to put real time captions on any video source.
Many languages and dialects can be selected for captioning, and is a perfect fit for churches, classrooms and other
presentations.
Network Connection Required
A network connection to the Caption Assist is required. The Caption Assist depends on access to the Google Cloud
to receive its captioning data.
General Installation
The Back Panel
Most wired devices will connect via one of the ports on the back panel. There are numerous ports to connect to,
including USB, HDMI, COMM ports and a Phoenix-Style connector.

Back Panel Diagram
Connecting the Video Source and Outputs
HDMI Connectors
To connect HDMI video:
HDMI Input into Caption Assist: Using HDMI video cable, connect the cable to the HDMI In port on the back panel
of the Caption Assist.
HDMI Output from Caption Assist: Using HDMI video cable, connect the cable to the HDMI Out port on the back of
the Caption Assist to HDMI In on a HDMI display.
Required Use of Multiple Devices
The output typically cannot be connected to the same device as the input. For example, laptops do not have an
HDMI In port, but do have an HDMI Out port.
Any data sent to the HDMI Output is also sent out via a digital stream, which is viewable from the SoundPlus Media
Player.
Displaying the stream or output into the same device as the input will cause video to show a video of itself, creating
a visual echo.

7
Caption Assist
A visual echo loop is a repeating, nested video feed.
This is not desired as the video will repeat itself within itself, like filming yourself in a mirror. Audio echo may also be
introduced, depending on the configuration.
Connecting Devices
IMPORTANT: Be sure to power down the Caption Assist before connecting or disconnecting any controllers. The
Caption Assist will automatically detect installed controllers upon turning the power on. If you change controllers or
add a new controller, you need to turn power o, install the new controller(s), then turn the power on.
Connecting the Keyboard, Tablet or other USB Devices
Connect the device(s) to any USB port on the Caption Assist. The system supports up to 5 USB 3.0 devices and 1
USB B device.
Connecting the Phoenix Connector
Connect the wires from your power controller (or other device) to the Caption Assist’s Phoenix-style connector
(labeled on the back of the device as PWR SW). When the relay is thrown, the Caption Assist will power on or o, as
a toggle.
Connecting a 3rd Party Controller - COMM Port Wiring Issues
Customers sometimes encounter issues with the wiring of controllers. The following information may be helpful in
resolving any issues.
• Caption Assist’s COMM ports sometimes use pin 9 to supply power to the RS-232 line drivers. Pin 9 was
selected because it’s specification is seldom used. If you are connecting a device other than a line driver to a
COMM port, the voltage may cause unexpected issues with the device.
• COMM 2 is set up as the default control port.
• COMM 1 and COMM 2 have jumpers for power on pin 9, and are set to OFF when shipped from the factory. If
you require power from either or both of these COMM ports, please contact technical support.
Connecting USB Devices
A USB Mouse or Keyboard, Video Device, or other USB devices can be connected via the USB ports on the back
panel.
Connecting Analog Audio Input
Analog audio input cannot be directly connected to the Caption Assist. However, an XLR to USB cable is included
with the device to help convert the analog input connections to USB. You may be able to use other similar cables if a
XLR connection does not work for your audio setup.
