16 • Hardware Overview SRG-2200 User Guide (v6.0)
If the SRG-2200 is to be used as a Master reference (i.e. not Genlocked), you do not have to supply a signal, and
you may leave these BNCs unconnected. However, it is always wise to add a termination onto one BNC of an
unused looping pair, in order to avoid having a “floating” input.
2. Word Clock Connectors
This BNC provide output of Word Clock (48 kHz or 44.1 kHz).
3. LTC Connector
This BNC provides an LTC output.
4. DARS OUT Connector
This BNC provides a DARS output.
5. AES AUDIO OUT Connectors
These 2 BNCs provide AES Audio outputs.
6. COMPOSITE OUT Connector
This BNC provides an output of the selected Analog Composite Video Pattern. The output format can be PAL,
NTSC-M or NTSC-J.
7. TRI BLACK OUT Connectors
These three BNC provide outputs 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 outputs are completely independent from each other.
8. SDI 1 and SDI 2 Connectors
These two BNCs provide the selected pattern and black output 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.
9. DIP Switches
Use the DIP switches to force the IP Address and Subnet Mask for the SRG-2200 to known values.
10.ETHERNET 100-BASE T Connector
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 e.g. PTP messaging, 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.
11.POWER Connectors
The SRG-2200 is designed to operate from an ex12V DC power source. A safety earth stud is provided
for earth bonding the chassis if you so require.
You need to provide two power connections (for the two ex12V DC Power Bricks). For full power
security, these should be separate, independent and secure power grids. However, you still gain the security of
power supply failure redundancy if you use the same power grid for both connections.
12.PSU Status LEDs
These LEDs indicate presence or absence of +12V.
