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

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

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.

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.

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

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

The Caption Assist can display streaming video output over the SoundPlus Media Player. The video will match any

HDMI video output. The player will let you select from any stream sent from a Caption Assist system.

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.

submenu sometimes displays a second submenu of choices based on the selection you make.

Outline Format: The entire menu system is an outline format that allows you to drill down to the speciﬁc option you

wish to change. Whenever the Main Menu is visible, you can select directly from it to activate a dierent branch of

submenus.
