KONA 3G Installation and Operation Manual — Cable Connections

Descriptions—Cables
and K3G-Box
Connectors on the standard cable set are labelled as to their function for easy installation and
maintenance. Similarly, connectors on the optional Breakout Box are also labelled.
8-Channel Digital AES/EBU Audio Inputs And Outputs
When using the standard cables, BNC connections are provided for 8 digital AES/EBU audio
input/output.
The optional Breakout Box provides 16 BNC audio connections on the front panel.
Analog 2 Channel Unbalanced Audio (Breakout Box only)
On the optional K3G-Box are two analog output connectors, one for each channel. These
connectors are RCA-style phono jacks.
RS422 Machine Control
A DB9 connector provides connection to VTRs, digital disk recorders, and other devices using
RS422 device protocol. For the breakout cable the connection is male and for the breakout box
the connector is female. (Connector pinout is listed in Appendix A: Specifications.)
SDI Input and Outputs
In Standard Mode, mini-connectors are provided for two SDI inputs and two SDI outputs for
single or dual-link. A cable with four Mini-connectors on one end and four BNCs on the other
end is provided for connecting equipment to the SDI inputs and outputs. This cable is also used
to interconnect between the KONA 3G board to the optional K3-Breakout Box.
KONA 3G offers 4 video outputs in SD and HD—2 SDI outputs that are used for both high-
definition and standard-definition (SD/HD-SDI), and an analog video output (configuration of
this three BNC cluster is discussed later with regards to component, composite and Y/C). Each of
the three outputs is independently switchable between HD and SD. For example, if you are
working in HD, you can have simultaneous HD-SDI, SD-SDI, and HD-component analog output.
A fourth output via HDMI 4.1a is also provided.
When the KONA 3G is reconfigured for 4K Mode and a 4K format is selected, all four of the mini
BNCs are used as outputs for each of the 4K playout quadrants. There are no SDI inputs available
in 4K formats. If a format of 2K or less is selected the normal SDI inputs are available (see
“Using
4K Mode” on page 88
for more information on 4K output mapping).
SDI inputs and outputs support video as well as 16-channels of embedded 24-bit digital audio.
Use SDI wherever possible for the best quality 10-bit uncompressed video input, capture and
output. If peripheral equipment has a variety of inputs/outputs, look to see if it has SDI I/O, and
