The BlueBox™ SDI-To-IP Encapsulators (hereinafter “BlueBox™ SDI-TO-IP”) provide a
small “throwdown” package that provides the flexibility of SDI-to-IP encapsulation as well as
providing an HDMI output, a reclocked SDI coax output, and a convenience analog stereo
de-embed monitor pair with built-in Lt/Rt downmixer.
Note: BlueBox™ SDI-TO-IP does not perform format cross, up, or down-conversions.
The unit receives its DC power from either connecting its USB port to associated equipment,
or by the supplied AC adapter.
Connecting BlueBox™ SDI-TO-IP
1
Connect BlueBox™ SDI-TO-IP to DC power using either or both the USB port or the
supplied AC adapter. Dual source (simultaneous) use provides power redundancy.
2.
Connect Fiber IP and SDI input and/or HDMI outputs. This provides the basic
encapsulator connections. Other connections do not require termination if unused.
Status Indicator
BlueBox™ SDI-TO-IP has a Status LED on the side of the unit which functions as follows:
• Solid Green – SDI present and being encapsulated; HDMI has sync.
• Green Flash – No SDI; no HDMI sync.
• Solid Green w/ brief Red Flash – SDI present, but no HDMI sync.
• Amber Flash – Device setting has been changed via BBGConfig USB remote control and
waiting to write (store) in memory. This lasts about 10 seconds following a setting change.
No amber flashing indicates change is stored in non-volatile memory.
• Red Flashing – Indicates device is in boot loader mode (this mode is invoked when device
firmware is being upgraded).
Audio De-Embedding
BlueBox™ SDI-TO-IP provides de-embedding from the SDI source input to analog audio
outputs. Refer to illustration on rear label on unit for switch positions.
• SDI channels Emb 1-8 are normally routed to HDMI channels 1-8.
• SDI embedded channels 1/2, 3/4, 5/6, or 7/8 can be de-embedded to the stereo
AN-AUD L/R OUT TRS 3.5mm stereo connector using DIP switch bank as shown on the unit label.

Unbalanced Audio Levels and This Device
The unbalanced audio outputs on this device (available on the AN-AUD L/R OUT TRS 3.5mm stereo
connector) correspond to 2.2 Vrms output when sourced from a unity-gain 0 dBFS digital sine-wave source.
Consumer audio is specified in dBV with a nominal (or recording) level of -10 dBV. The 2 Vrms maximum
output level corresponds to +6 dBV. The unbalanced analog outputs on this device allow for 16 dB of
headroom above the nominal -10 dBV consumer level (“headroom” is the range between the maximum and
nominal audio levels). Professional balanced analog audio levels in the US typically use a +4 dBu nominal
level with 20 dB of headroom (-20 dBFS). The maximum level for balanced analog interfaces is +24 dBu.
The headroom difference between consumer and professional audio will result in a lower consumer level
when converting from professional balanced analog audio. For example, if pro level analog audio is
received and transmitted via AES or embedded SDI to a receiver converting to unbalanced analog audio,
the output will be 4 dB lower, with a nominal level of -14 dBV.
Channel Line-Up of HDMI vs. Standard SDI Conventions
To maintain conformance with CEA-861D HDMI audio channel line-up specifications and industry standard
SDI convention, this device has a DIP switch that selects audio line-up on the HDMI output as listed below
(SDI output line-up and encapsulation is always per SDI convention)
.
Configure Select Using DIP Switch Bank
BlueBox™ SDI-TO-IP can be used in a local control mode using DIP switches to configure
settings, or via USB remote control. Refer to diagram on unit label for switch positions.
• If using DIP switch control, make certain switch SW1 is set to ON. USB remote control
is locked out in this mode.
• If using USB remote control, make certain switch SW1 is set to OFF. DIP switch local
control is locked out in this mode.
HDMI/DVI Mode Switches
BlueBox™ SDI-TO-IP can typically automatically detect connection to a downstream device
as either an HDMI port or a DVI (monitor) port. However, switches SW8 thru SW10 allow
setting BlueBox to force a DVI output suitable for direct connection to monitors using a DVI
input in case the connection is not detected by the monitor. (Refer to illustration on rear panel
label on unit for switch positions.)
• SW8 – Set to ON to allow manual control of HDMI/DVI mode.
• SW9 – Set to ON to force DVI output mode.
• SW10 – Set to ON to force RGB color space (intended mode for monitor usage).
Note: Connect monitor to BlueBox™ SDI-TO-IP and then set switches to ensure monitor gets
handshake to “see” connection.
