4. BLACK 1 Output
This pair of BNCs provides two outputs of Analog Composite Video Black-Burst. The output format is always
the same as that selected on the COMPOSITE output.
5. TRI/BLACK 2, 3, and 4 Outputs
These three pairs of BNCs provide two outputs each of either Analog Composite Video Black-Burst in PAL,
NTSC-M or NTSC-J, or any one of the supported Tri-Level Sync formats. These three pairs of outputs are
completely independent from each other.
6. SDI 1 and SDI 1 BLACK Outputs
These two pairs of BNCs provide two outputs each of the selected pattern and black in Standard Definition, High
Definition or 3G Video, in any of the supported formats. The signal format of the black output follows that of the
Pattern output.
7. SDI 2 and SDI 2 BLACK Outputs
These two pairs of BNCs provide two outputs each of the selected pattern and black in Standard Definition, High
Definition or 3G Video, in any of the supported formats. The signal format of the black output follows that of the
Pattern output.
8. Ethernet 100-Base T
This rear panel connector is a standard RJ45 Ethernet connector. This connection is required for DashBoard
connectivity, NTP services, software upgrades, etc.
 The 100Base-T network port is used for status and control (DashBoard). In an environment where broadcast
and/or multicast traffic is present, it is important to limit the number of broadcast and/or multicast messages that
reach the 100Bast-T port to a very low number. This is normally configured in the
Storm Control
configuration
of your network router. A limit of zero broadcast and/or multicast messages is recommended. If this is not
available then choose < 10 broadcast and/or multicast messages per second.
9. GbE/PTP
This port is for the option PTP interface.
10.BALANCED AUDIO / AES / LTC Outputs
This 30-pin multi-way connector provides outputs of Analog Balanced Audio, AES Audio, and LTC. These are
user configurable via DashBoard.
11.GPS Input with +5v DC Output to Power Antenna
This coaxial connector is used to connect a suitable GPS aerial in order to be able to Genlock the SRG-4500, and
to provide accurate time and date information. The GPS-4500 option key is required.
12.1Hz Output
This BNC provides an output of the 1Hz pulse.
13.10MHz Input
This input accepts a standard 10MHz reference signal.
14.10MHz Output
This BNC provides an output of 10MHz derived from either the extremely stable internal oscillator, or
looped-through from the 10MHz IN. A relay controls which signal is routed to this output.
15.WK/TTL1, WK/TTL2, and 6Hz/TTL3 Outputs
These three BNCs each provide independent outputs of either Word Clock or 6Hz, or any one of a selection of
traditional pulses, e.g. Mixed Sync, Mixed Blanking, etc.
16.DARS Output
This BNC provides an output of DARS (Digital Audio Reference Signal).
