Instruction Manual, SMPTE HUT INTRODUCTION 2
INTRODUCTION
The SMPTE HUT system enables you to replace long runs of the
bulky and expensive hybrid fiber cable that connects your camera
and CCU with inexpensive fibers alone. It does this by moving
the camera power injection from the CCU side to the cam side.
It consists of a breakout adapter, known as the HUT-CCU, that
attaches to the SMPTE connector on your CCU. This enables you
to connect 2 fibers going to the cam side using ST connectors,
and it also tricks the CCU into thinking that your camera is still
attached by the hybrid fiber cable.
At the cam side of these fibers is the CAM HUT, which takes these
2 fibers with ST connectors and routes them to a SMPTE hybrid
fiber connector. It also plugs into local mains power and injects
230 VAC for your camera into that same SMPTE connector which
now connects to the camera via a much shorter length of hybrid
fiber cable. The CAM HUT performs the same safety checks on
this cable as your CCU does, and it optionally allows remote
powering down of your camera from the CCU side as well as
optical repeating and remapping of the wavelengths to and from
the CCU.
FEATURES AND OPERATION
CAM HUT (cam side) unit
The CAM HUT basic version is shown in Fig. 1. There are 3
versions of the CAM HUT, described below.
There are 2 versions of the CAM HUT, and each has its own front
panel. These are shown in Fig. 2. The basic configuration, which
is the first panel, is to have the SMPTE hybrid fiber connector
to the camera and the 2 ST/UPC or duplex LC fiber connectors
populated on the front panel. These are labeled FROM CCU
and TO CCU. Optionally, the optical connectors can be located
on the rear panel instead, as shown in Fig. 3. In systems with
the optional optical repeater, it is important that the user be sure
that his up-link and down-link signals are matched to the proper
connectors consistently throughout the link.
Front Panel
RESET: This button resets a 2A thermal circuit breaker in series
with the SMPTE hybrid connector output. In the event of an
over-current fault that causes power to the cam to be removed,
as evidenced by the HV PRES LED being dark, and the button
popped out. Pressing this button restores power after the fault
is removed. Note that RESET does not restore functionality if a
SMPTE cable fault exists.
SMPTE CABLE Status LEDs:
SHORT: Glows red upon short or leakage of hybrid fiber cable
to ground. Upon power up, this LED may glow red for a few
seconds even if no short exists. This is normal.
OPEN: Glows red when cable is open or cam not connected. If
using a Hitachi camera, be sure to set the CAM TYPE switches to
the Hitachi positions, to bypass the OPEN cable test. Otherwise,
it will always fail. For Panasonic, Sony or Ikegami, set switches
for those cameras.
OK: Glows green indicating a properly connected hybrid fiber
cable.
HV ENAB: Glows green when the HUT attempts to apply 230VAC
to the hybrid fiber cable. This occurs only after all cable checks
have been completed successfully.
HV PRES: Glows green when 230VAC is actually present on
the hybrid cable. If HV ENAB is green but HV PRESS is o,
check to see if the circuit breaker has been tripped. If so, the
RESET button may need to be pressed after removing the fault.
Otherwise, there could be a failure of either the HUT relays or
power transformer, and the HUT will require service.

3FEATURES & OPERATION Instruction Manual, SMPTE HUT
Optional Front Panel Features
If ordered with the optional Optical repeater, besides the features
of the basic unit, the front panel will have these additional
features as shown in the second panel:
Optical Status Leds:
If the complete optical repeater option that allows optical
remapping is fitted, there are 2 LEDs labeled FROM CCU and
TO CCU for the 2 optical fibers. Each glows red if the received
optical strength of its fiber is less than -18db, and green if greater.
However, if only the remote shutdown feature is fitted, only the
FROM CCU LED will be shown on the front panel. The TO CCU
fiber path will be entirely passive, and is passed straight thru the
CAM HUT.
REMOTE enable switch:
Set to on to enable the Cam HUT to prevent HV from being
applied to the camera if fiber FROM CCU is not illuminated. Fiber
FROM CCU is assumed to be the fiber up-linking from the base
to the camera. This eectively places the camera in standby,
as only standby voltage can be applied. If fiber FROM CCU is
illuminated, the Cam HUT will enable the application of HV if all
other cable checks have been passed. If the REMOTE switch is
set to o, this feature is bypassed and the application of HV will
be determined by the cable checks alone. Functionality will then
be identical to the basic unit.
Rear Panel Features
The rear panel is shown in Fig. 3. This drawing shows an
optional location of the optical connectors on the rear. The same
considerations concerning the fiber optic connectors should be
observed as on the front panel. Also on the rear is a fused, filtered
power entry module that accepts an IEC cord and a primary
power switch. If the optical connectors are located on the front
panel as shown in Fig. 2, then the rear would be completely
blank except for the power entry. If pressing the RESET button
after an over-current fault has occurred does not restore power,
please check the fuse.
Configuring the Operating Voltage:
The unit is configurable for either 115 or 230V operation. The
CAM HUT must be set for the correct mains voltage or damage
may result. The default configuration is for 115V operation. To
reconfigure the CAM HUT for a dierent mains voltage, using a
screwdriver, slide the red voltage select switch on the rear panel
to the correct mains voltage.
Base (CCU side) Unit
The Base unit, known as HUT-CCU, has a SMPTE hybrid receptacle
panel mount connector for connection to the CCU and 2 ST/UPC
or duplex LC connectors for the fibers to the CAM HUT. The base
unit is shown here in Fig. 4 with ST connectors As on the CAM
HUT, the ST or LC connectors are labeled either FROM CCU and
TO CCU. The same considerations concerning the fiber labels
should be observed, as on the CAM HUT.
The HUT-CCU acts as a breakout for the optical ports in the CCU
SMPTE connector. It also tricks the CCU into thinking a camera
is attached by a SMPTE hybrid fiber cable. This is necessary to
enable the CCU to leave standby mode so that it can accept video
from the camera. It has 2 LEDs located on the panel with the
ST connectors, labeled Power and HV. The Power LED is green
the CCU is supplying power to the HUT-CCU, and the HUT-CCU
is attempting to spoof the CCU. The HV LED is green when the
CCU is supplying high voltage. This means that the HUT-CCU has
successfully spoofed the CCU into thinking a camera is attached.
Otherwise, the CCU will not leave standby mode.
