Rear Panel Overview
Figure 4.2 shows the SRG-4400 Rear Panel with descriptions of the rear-panel connectors.
In the basic configuration, the entire bottom row of BNCs are present, together with the Ethernet
connector and the GPI/RS232 facility. Also, the left-hand group of connectors along the top row
will be present.
The remaining BNC holes (top row, right-hand group - currently not implemented) may be used
for future option modules.

1. Power Connectors
The SRG-4400 is designed to operate from a single-phase power source with the neutral
conductor at or near earth ground. The line conductor is fused for over-current protection. A
protective ground connection through the grounding conductor in the power cord is essential for
safe operation. Safety earth studs are also provided for earth bonding the chassis if you so require.
The SRG-4400 operates from an AC line frequency of 48Hz to 63Hz, over the range of 85VAC to
250VAC, without the need for user configuration. Refer to the chapter “
Specifications ” on
page 7-1 for additional information on power and environment requirements.
You need to provide two power connections (for the two Power Connectors). For full power
security, these should be on 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.
2. REF LOOP
This pair of BNCs allow the input of a remote reference signal. This signal may be NTSC or PAL
B/G.
With the reference signal applied to one BNC, the other BNC must be terminated (or connected to
another unit which is ultimately terminated).
If the SRG-4400 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.
3. COMPOSITE Output
This pair of BNCs provides two outputs of the selected Analog Composite Video Pattern. The
output format can be PAL, NTSC-M or NTSC-J.
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.
