INTRODUCTION
Thank you for choosing a Sound Associates, Inc. manufactured product. All Sound Associates’ products are carefully
designed and engineered for cutting edge performance and world class reliability.
I-Caption® is a state-of-the-art, wireless visual aid that provides verbatim closed captions and subtitling on an
individual hand-held receiver. Originally designed for live theatrical productions, this fully automated system displays
dialogue, lyrics, and sound effects with the efficiency of real-time captioning at a fraction of the cost.
The T4 is designed to serve as both the transmitter and repeaters for the I-Caption®, D-ScriptiveTM and Audien®
Translation systems. It transmits cue information from the control station to R6 audio and video hand-held receivers.
The fully automated system is designed to display captions, audio description or multilingual commentary to wireless
receivers.
The T4 Transmitter when coupled with the R6 Receiver and the CS-6 Control Unit will display I-Caption® slides of
verbatim closed captions or subtitling. The T4 can also trigger playback of prerecorded audio files in mp3 format on
the R6 for audio description for the blind or multi-lingual audio commentary.
FEATURES
 Utilizes an innovative 900 MHz (2.4 GHz for international use) mesh network specifically designed to work in
high traffic radio transmission areas.
 Wireless repeaters can be added as needed. Covers approximately 300 ft (200 ft at 2.4GHz) radius in ideal
situations.
 Strong metal case with EtherCon Connectors makes it extremely durable in harsh environments.
 Universal mount allows it to attach to wall, ceiling, or microphone stand.
 Hardwired transmit and receive RS-485 data and power down a standard CAT5E / CAT6 cable terminated in
an EtherCon connector.
UNIT TYPES
I-Caption® T4 – The Main Coordinator.
 This unit must be hardwired to the Control Station directly. The T4 is the main unit and will communicate
with all additional repeaters.
 T4 must be locally powered to ensure proper transmission.
 The EtherCon connector is terminated in standard ethernet format.
I-Caption® T4R – Wireless Repeaters.
 This unit will repeat the main signal transmitted from the T4 Coordinator. The repeater can be hardwired out
of the T4 Coordinator or repeat wirelessly if within range of the T4 Coordinator or another repeater.
 Wired and wireless repeaters must be powered locally with 5-7 VDC.
 Note: If hardwired, the repeater should not be in range of the T4 Coordinator or other hardwired T4R
repeaters. Cue fires can be interfered with when two hardwired units on the same network are in range of
each other.

Version 1.2 October 2023
If the unit is damaged due to shipping, please keep all packing material and contact the shipping
company as soon as possible. Only the consignee may institute a claim against a carrier if damage has
occurred in shipping; however, Sound Associates will assist in any such event.
MOUNTING
The T4 can mount to a wall or microphone stand with a M 10 mounting bracket.
The T4 utilizes a small speaker mount to secure units to ceiling, walls or microphone stands. Sound Associates
offers the M -10 that includes hardware to attach to a T4 chassis to wood or sheetrock walls and / or microphone
stand. See diagram below.
Each mount attaches to the emitter via two 3/8” 8/32 screws (Note: The mounting screw can not exceed 3/8”
because the screw will damage the PC board).
After deciding on the location of the transmitter / repeater, fix the mounting plate of the M 10 to a secure flat surface
with two screws or bolts with a maximum diameter of 1/4 inch. To allow for proper transmission coverage, the T4
antenna should be mounted 12 inches from all major metal objects. Metal will interfere with wireless transmission.
Use safety wires where necessary when mounting above seated areas.
BOTTOM PANEL CONNECTIONS / CONTROLS
1 – Sign l / Power Input: EtherCon Connector inputs RS-485 signal
from Control Station or Computer. Use a standard Ethernet cable
terminated with an EtherCon or standard Cat 5E connector.
2 – Sign l / Power Output: EtherCon Connector outputs the RS-
485 signal to hardwired remote T4R Repeaters. Use a standard
Ethernet cable terminated with an EtherCon or standard Cat 5E
connector.

TOP PANEL CONNECTIONS
6 – Antenn Connection: Screw ¼ wave swivel antenna to RP-SMA threaded
connector on top of unit. Make sure Antenna does not touch or is blocked by and
metal objects.
POWER CONNECTION
The transmitter is shipped with a 5-7 VDC power supply. The power supply is wired with the inside +DC
and the outer shield as -DC. The DC power supply is equipped with a screw type power plug, make sure
it is fully inserted before tightening the casing screw clamp.
INPUT & OUTPUT CONNECTION
The T4 Coordinator and T4R Repeater have one input and output. It receives power and RS485 data via
a standard CAT 5E cable terminated in standard RJ45 module connector or a rugged lockable Neutrik
EtherCon Connector.
The units use the same wiring configuration as a standard (Straight Thru) CAT 5E cable.
THEORY OF OPERATION
The primary T4 Transmitter / Coordinator is hardwired to the control unit and broadcasts cue information to the
receivers via a wireless mesh network in the 900 MHz or 2.4 GHz range. Additional T4 Repeaters can be added to
the network to increase coverage. Repeaters can be either wireless or hardwired with CAT5E / CAT6 cable
terminated in an EtherCon connector. Voltage is supplied to the T4 via the CAT5E cable for cable runs under 50 ft,
otherwise local 5-7 VDC is required.
The T4 Coordinator and T4R Repeater unit incorporates a sensitive RF transceiver utilizing a peer-to-peer protocol
900 MHz North America and in 2.4 GHz range for operation in global markets. This innovative mesh protocol offers
added network stability through self-healing, self-discovery, and dense network operation.
