Table 2.1: Types of Connector
Type of Connector
Description
SDI IN
A 75
Ω
BNC connector provides a serial digital video input
to the unit. This input is terminated in 75
Ω
.
HD SDI INPUT
A 75
Ω
BNC connector provides an HD serial digital video
input to the unit. This input is terminated in 75
Ω
.
COMP VIDEO
A 75
Ω
BNC connector provides a high quality analogue
video input to the unit.
H SYNC
Optional - Studio Black and Burst should be fed to the
75
Ω
BNC connector (H SYNC). This genlocks the
Encoder to the Studio system. This method may be
required with some audio formats, or for locking
Encoders to an evolution 5000 Multiplexer.
Audio In
The 15-way, D-type male connector is used in different
ways according to the audio input and the encoding
configuration selected.
The connector provides two stereo pairs which may be
independently configured as either analogue or digital.
The left channel is used to input digital audio.
The Encoder is supplied with a break-out cable which
plugs into this connector, and provides a more
convenient means of connecting the audio signals via
five connectors. There are four XLR female connectors,
with the fifth cable being a BNC which provides an
AES/EBU 75
Ω
digital reference output. This is for when
the unit is connected to an external Dolby Digital
Encoder.
ASI OUT 1, 2 and 3
A 75
Ω
BNC connector provides the output from the
Encoder. Connect the Multiplexer or Modulator ASI cable
to the appropriate ASI OUT connector, using good
quality 75
Ω
coaxial cable (for example, BBC PSF 1/3).
Ethernet #1 and #2
An 8-way, RJ-45 connector provides a 10BaseT Ethernet
interface for communications with the TDC/MEM for
control and monitoring. The Encoder has a single
switched Ethernet channel. Ethernet#1 is selected as
default at power-up. If a carrier is not detected on
Ethernet#1 then the input switches to Ethernet#2. This
gives a redundant Ethernet control via two hubs.
RS-232/RS-485
Control
A 9-way, D-type male connector provides an
RS-232/RS-485 port for remote control of the Encoder.
This connector is wired as a DTE.
Alarm
If required, connect an external status monitoring device
to the ALARM connector. A 9-way, D-type male
connector provides an alarm relay interface which can
be used to send a signal to remote equipment.
RS-232
RS-232 data is available on the Base Board and the
option module M2/EOM2/DAT.
RS-422
A 15-way, D-type female connector provides an RS-422
synchronous, serial communications data input interface.
Technical Earth
Connect the Encoder's Technical earth to a suitable
point.
