Introduction to the SapphireTX Transmitter
The Sa hireTX camera-back transmitter, integrates a True 4K HEVC encoder with a
COFDM modulator creating a single, slimline ackage, suitable for camera-back mounting
whilst su orting twin SFP cages, thus allowing video in ut in formats of Single 3G-HDSI,
Quad 3G HD-SDI, 12G and Dual 6G (Arri format).
Back to back V Lock or Anton Bauer battery lates facilitate ass-through ower whilst an
additional external ower connector is rovided at the base. Analogue stereo audio in uts
are su orted as well as camera control and Tally interfaces.
Sa hireTX is equi ed with a high-quality, low- latency H.265 (H.264 is also available)
encoder ca able of UHD and HD formats in 10bit 4:2:2 with automatic HDR su ort.
Sa hireTX-D additionally su orts legacy DTC low-latency HD H.264 encoding.
U to 8 stereo airs of audio in either MPEG-1 layer 1, or PCM format (4 stereo airs in
AAC-LC) can be extracted and encoded by The Sa hireTX whilst analogue audio in uts
with ower are included for direct micro hone connection.
Camera control and functionality is accessible through a single colour anel on the side or
using the web browser interface; BWS’ camera control being su orted as standard with the
o tion of future u grade to Bi-directional IP camera control.
Key Features
• Low latency UHD/HD Resolution encoding.
• SFP Interface su orting 12G, Dual 6G, Quad 3G interfaces
• Interchangeable RF Modules
• Interchangeable Camera Control modules including Bi-directional IP

SFP Modules are o tional and will be su lied if ordered
Fitting Embrionix SF modules to the SapphireTX
Transmitter
The video in ut to the Sa hireTX requires SFP modules to be fitted. BWS can su ly
these modules at time of ordering or they can be sourced se arately by the customer. BWS
recommends the Embrionix EB12HD2R-MNR-2 module for roviding 3G, 6G and 12G
interfacing o tions.
12G Single EB12HD2R-MNR-2 module required

Modules can be fitted by sliding them carefully into the SFP Cages and ressing gently until
a retaining click is felt.
For 12G and 6G 4K video camera interfacing only a single SFP module need be fitted in
SFP cage 1, equally if HD using 3G SDI is required only a single module is needed in cage
1. For Quad 3G 4K video, two modules must be fitted.

Installing the SapphireTX Transmitter to the Camera
The Sa hire-TX is rovided with front and back battery lates with through ower. The
battery lates can be Anton Bauer or VLock style.
The Sa hireTX is designed to sit between the camera body and the battery, roviding
ower through to the camera. Video from the camera body should be connected to the
a ro riate HD-BNC on the base of the unit, de ending if 12G, Quad HD or single HD are
rovided by the camera.
An exam le of this configuration is shown below.

11
SapphireTX Camera Back User Manual
Using the SapphireTX in a System
Transmissions from the SapphireTX can be received on the BWS Sapphire-RXD receiver decoder. The
system should be connected as shown below. The SapphireTX and Sappire-RXD should be
positioned at least 20m apart during configuration to prevent the transmitted signals overloading
the receiver.
Critical Connections on the SapphireTX
1) The SapphireTX will need to be powered, this can be by connecting a battery such as a V-
Lock or Anton Bauer (model dependant) to the SapphireTX battery plate, or by connecting
the power in connector to a suitable power source (6-18V).
2) The camera video output should be connected to the SapphireTX video inputs, see previous
section for notes on 3G, 6G and 12G connection

12

Dual edestal Mode
When using Dual Pedestal mode for transmission, the receiver should be wired as shown
below.

owering on and getting started with SapphireTX
Transmitter
With the rimary connections in lace as described reviously, the Sa hireTX Transmitter
is ready to be owered.
The Sa hireTX Transmitter can be owered on by connecting a battery to the battery ate
(Anton Bauer or VLock) or by owering through the DC in ut on the base.
After a roximately 45 seconds the front anel will move from its ‘Initialising’ screen to the
‘Status’ Menu.
For successful transmission the following key arameters must be correctly set to match the
video source and to match the RF arameters to the receiver. Incorrect setting of these
arameters may result in errors in the encoder stream or ossibly no stream at all.
The key arameters can be set in the Configuration Menu (See Front anel Menu Structures
for more details).
Key arameters
Mode 1: 4K Ultra HD Mode
VIDEO FORMAT: The Video Format must match the video source eg. 2160 50 or 2160 59
SAMPLE FORMAT: The Sam le Format must match the video source eg. SQD (Square
Division) or 2SI (two sam le Interleave)
FREQUENCY: The frequency must match the frequency set at the receiver
RF OUTPUT: Must be set to ON
RF POWER: Must be sufficient to transmit to the receiver ty ically this is set to 100mW
MODULATION: Must be set to match the receiver ty ically this is set to DVBT
BANDWIDTH: Must be set to match the receiver ty ically this is set to 8MHz
CONSTELLATION and FEC: Must be set to match the receiver and also to give sufficient
bitrate for the video being encoded, for UHD this might be 64QAM FEC1/2
PIDS: All the PIDs (video, Audio, PRC and PMT) should match between the Sa hireTX
Transmitter and decoder. The decoder does have an auto service mode to sim lify this
rocess.
Mode 2: HD Quad Mode

1
SapphireTX Camera Back User Manual
To encode 4 HD services simultaneously see the section entitled Quad Mode. To encode a
single HD service set the arameters as follows.
VIDEO FORMAT: The Video Format must match the video source eg. 1080 50
FREQUENCY: The frequency must match the frequency set at the receiver
RF OUTPUT: Must be set to ON
RF POWER: Must be sufficient to transmit to the receiver ty ically this is set to 100mW
MODULATION: Must be set to match the receiver ty ically this is set to DVBT
BANDWIDTH: Must be set to match the receiver ty ically this is set to 8MHz
CONSTELLATION and FEC: Must be set to match the receiver and also to give sufficient
bitrate for the video being encoded, for UHD this might be 16QAM FEC2/3
PIDS: All the PIDs (video, Audio, PRC and PMT) should match between the Sa hireTX
Transmitter and decoder. The decoder does have an auto service mode to sim lify this
rocess.
Front anel Status Indicators
Status data is resented on the front anel screen of the Sa hireTX Transmitter.
The front anel screen has two key status indicators.
Video Lock
Video Lock status is available from the Status Screen. To achieve video lock, a suitable
video signal should be connected to the video in ut connectors and the correct video format
and sam le format should be selected by the user.
Battery Voltage
Battery voltage allows the o erator to monitor the voltage status of the battery and change
the battery before this becomes too low.
Changing Video Format UHD and HD
The switch between Mode 1 (4K Ultra HD Mode) and Mode 2 (HD Mode), is achieved using
the VIDEO FORMAT command from the configuration menus. The selected VIDEO
FORMAT must match the video format su lied at the in uts to the Sa hireTX Transmitter.
Ultra Low Delay vs. Low Delay and Normal Delay
The Sa hireTX Transmitter has three styles of encoding, Ultra Low Delay, Low Delay and
Normal Delay. In Ultra Low Delay the encoder is o timised to minimise end to end video

latency. The latencies shown below can be achieved when using a Sa hireTX Transmitter
and Decoder in Ultra Low Delay mode.
4K Ultra HD 59 (2SI format) = 66ms
4K Ultra HD 50 (2SI format) = 75ms
HD 1080 59 = 55ms
HD 1080 50 = 70ms
Note: If the new BWS B150 decoder is used then the above latencies will be significantly
less and ty ically <35mS)
In Ultra Low Delay mode the encoder is not o timised to achieve best image quality. In user
scenarios where signal delay is not a key concern, then Low Latency or Normal Latency
rather than Ultra Low Latency should be em loyed. In Low latency and Normal latency
mode a noticeable im rovement in image quality can be achieved for a given bitrate.
Audio Sources
The Sa hireTX Transmitter su orts three sources of audio, these sources can be selected
from the front anel AUDIO SOURCE arameter. The sources are:
Analogue Audio: Connecting the su lied audio in cable roviding 2 x Left / Right XLR
connectors. Line and micro hone level audio are su orted with 48V hantom ower
available.
Embedded Audio: Audio is extracted from the video stream.
Test Tone: An internally generated 1KHz test tone.
