Precautions:
1. Power – WARNING, BEFORE TURNING ON THE POWER FOR THE FIRST TIME, READ THE FOLLOWING SECTION
CAREFULLY. The unit is designed for use only with the line cord of the region in which it will be operated.
2. Voltage Label (Rear Panel) – A label located at the rear panel power connection indicates the power input for the
unit.
3. Do Not Plug in the HDMI input, output, Comm 1, Comm 2, Ethernet, or USB connections while the power switch is
switched to the ON position.
4. Do Not Touch any part of the Caption Assist with wet hands. Do not handle any part of system, including the
power cord, when your hands are wet or damp. If water or any other liquid enters the Caption Assist or Caption
Assist‘s location, take the device to qualified service personnel for inspection.
5. Place all components of the Caption Assist in a well ventilated location. Take special care to provide plenty of
ventilation on all sides of the system components, especially when it is placed in a small location, such as a rack.
If ventilation is blocked, the system may over heat and malfunction.
6. Do not expose the Caption Assist to direct sun light or heating units as the system’s internal components
temperature may rise and shorten the life of the components. Avoid damp and dusty places.
7. Care – From time to time you should wipe o the front and side panels and the cabinet with a soft cloth. Do not
use rough material, thinners, alcohol or other chemical solvents or cloths since this may damage the finish or

operate normally, or if the unit has been dropped.
Do not block any ventilation openings. Install in accordance with manufacturer’s instructions.
Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus that produces heat.
Use only attachments/accessories specified by the manufacturer.
Unplug the transmitter during lightning storms or when unused for long periods of time.
Be advised that dierent operating voltages require the use of dierent types of line cord and attachment plugs.
Check the voltage in your area and use the correct type.
Use only the power supply provided by Williams AV. Other power supplies may have similar specifications, but
may not be equivalent in emissions ratings, in-rush current, etc. Use of an unapproved power supply may leave the
device partially or completely inoperable, and will void the warranty.
This apparatus has been designed with class-1 construction and must be connected to a main socket outlet with a
protective ground connection (the third grounding prong).
Protect the power cord from being walked on or pinched, particularly at plugs, receptacles, and near the power jack
on the transmitter.
The MAINS plug or an appliance coupler is used as the disconnect device, so the disconnect device should remain

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.

Caption Assist
Power On
To power on the Caption Assist:
1. Plug the power cord into the back of the Caption Assist and then into any grounded outlet.
2. Plug the power cords from any video source(s), controller(s), and display(s) into any grounded outlet.
3. Turn on each of the connected units, and then press the power button on the front panel of the Caption Assist.
NOTE: In order for the Caption Assist to properly sync with the video signals, the sources should be turned on first.
After a moment, a Caption Assist splash screen will appear, followed by the initializing of the ports, and ending with a
copyright message.
After the startup process, the default input source will be shown.
If this process is dierent for you, recheck your installation and power on again. Call Williams AV for support if it is
still unsuccessful.
NOTE: To bypass port initialization, press ESC during startup.
SoundPlus™ Media Player

Caption Assist Menu System
Overview
There are two Caption Assist menus. One is a series of icons that runs along the bottom of the screen with
commands a presenter would use frequently, such as starting a session.
The other menu is a larger, main menu system mostly used for setup and configuration. This menu will need to be
accessed to get your device connected to the network or calibrated properly.
Toolbar
A toolbar is available in the SoundPlus Media Player. The hamburger icon can toggle whether this menu is showing
or not. Switching the video source between HDMI or USB, the information screen, and the start or stop button are
available for quick access as well.
The Toolbar
Main Menu
The Main menu can be accessed by using a mouse connected to the USB ports on the Caption Assist to click the
top center of the output display. No physical button is visible. Pressing the Print Screen button on a USB keyboard
connected to the Caption Assist will also open the menu.
Click or use the arrow keys to navigate the menu system.

Menu Conventions
Once the menu system is displayed, you can make selections from it to navigate to the option(s) you wish to change.
Each menu selection has the appearance of a rounded-corner button.
Not Selected: If a button is not selected, it has a black background.
