IMPORTANT SAFETY INSTRUCTIONS:
The “GigaBUD 1000”, along with all of the components, are designed for indoor use ONLY. Direct exposure
to moisture must be avoided. Connect the modular power cable to the rear of the “GigaBUD 1000” BEFORE
plugging the other end into the wall.
Must be grounded to earth ground. Do not defeat the safety purpose of a ground-type or polarized plug. If
the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
Do not use extension cords to lengthen the power cord provided. Power cord must be accessible for the
removal of power from the unit.
SHOCK HAZARD
The video hub and remotely powered balun System meet UL/CSA Listed
compliance criteria as well as being FCC Part 15, Subpart B Compliant.
WARNING:
Failure to follow this guide can lead to malfunction of the system and invalidation of the warranty
OPERATING AND ENVIRONMENTAL WARNINGS
LASER RADIATION
A laser transmitter emits invisible radiation that can cause permanent eye damage. This product is used with
a combination of fiber optic components a cables.
AVOID DIRECT EXPOSURE TO LASER BEAM.
Operate all
components with proper fiber cabling. Disconnect power when making any cabling changes to avoid
accidental exposure.
Do not mount this unit with front panel facing upwards.
Each “GigaBUD 1000” is 2U and must be mounted in a 19” rack.
Airflow around the rack must be sufficient to maintain proper cooling of the “GigaBUD 1000”

General System Overview
The
Z-Band Video Distribution System
is designed to distribute the full spectrum
(54 to 860 MHz) of high quality, Analog and/or Digital Radio Frequency (RF) Video
from a CATV direct feed or a Headend (Sources) to Televisions and/or Set-top-
boxes (Receivers) in a building, campus or metropolitan area.
The Z-Band System utilizes Single-mode Fiber and/or Coaxial Cable for distribu-
tion in the Backbone and TIA 568 Certified Category 5e or better Twisted Pair
Cable for distribution in the Horizontal.
Quality Video begins with the Quality of the Video Signal and Noise Levels from
the Sources . The Z-Band System employs Intelligent Automatic Gain Control
(AGC) technology in the Backbone with the Z-Band Light Fiber Transmitter and/or
the GigaBUD Video Hub 1000 (GigaBUD 1000). In the Horizontal, the AGC is
maintained by the Z-Band Intelligent GigaBOB at each Receiver.
The AGC, in a coax based Backbone, is designed to maintain Video Signal
Integrity on a RG6 cable length of 400’ or less or a RG11 cable length of 600’ or
less; therefore, the RG6 or RG11 coax Backbone cannot exceed these limits.
If the Source Signal and Noise Levels are correct, the Z-Band AGC technology
will maintain Signal Integrity to each Receiver.
The Z-Band GigaBUD 1000 uses pins 7 & 8 of the twisted pair cable for the RF
Video and pins 4 & 5 for a return path in interactive system applications. Pins 1,
2, 3, & 6 are available for 10/100 Ethernet or other Auxiliary signals, such as
RS232 control, over the same cable (Shared Sheath) to the same destination
GigaBOB where they a broken out to separate the RF Video and Ethernet/Aux sig-
nals
The Z-Band System does not Switch, Route, Repeat, or in anyway interact with
the IP signal; we simply allow it to be sent over the same cable, to the same
destination..

Installation Recommendations:
Category Cable:
Category 6 or better cable for horizontal wiring plant per ANSI/TIA-568-C
Coax Cable:
Terminate with Compression Connectors
RF Signal and Fiber Test Meters:
RF Signal Meter
Fiber Optic Power Meter
Fiber Cable:
RF input power range to “Z-Band Light TX”: Set as close to 20dBmV Flat as
possible
Video Source Signal Levels and Noise Levels should be recorded for all
Channels prior to connection to the Z-Band Light Transmitter or to the
Master GigaBUD 1000/s
If Singlemode Fiber Patch Panels are Terminated with Connectors other than
SC/APC, special Patch cords must be acquired to address the Incompatibility .
RF Input Levels:
Make sure that the Signal Levels and Noise Levels are checked at the proper
locations (The proper locations for Signal Level readings are noted in each
specific installation drawing)
Spend the time needed to get the Source Signal and Noise levels to the
required levels . The Intelligent AGC of the Z-Band System will maintain the

Interconnecting GigaBUD 1000s in the Backbone
When a GigaBUD 1000 receives a video input signal from the Source it is
automatically designated as a
Master
, and becomes a
Level 1
device. This is
true if the Source connection is a Coax connection to the “CATV” input of a
GigaBUD 1000 or a Fiber connection to the “Fiber Input” port (Note: A GigaBUD
1000 with an internal Fiber Receiver is always a Master, while all non-fiber
GigaBUD 1000s may be either a Master of a Satellite Device). When a non-fiber
GigaBUD 1000 receives a coax signal at the “Cascade In” port, it is automatically
designated as a Satellite device (may be a Level 2, 3, or 4 device). The process
for connecting GigaBUD 1000 units together is called
Cascading
.
Each GigaBUD
1000 has 8 coax “Outbound “ ports which can be connected to the coax
“Cascade In” port of up to 8 Level 2 satellite GigaBUD 1000s. Each Level 2 device
can then connect to up to 8 Level 3 devices and each Level 3 device can connect
to up to 8 Level 4 devices. If all “Cascade Out” ports of all Level 1, 2, & 3 devices
are used, a single Master can Cascade together 585 GigaBUD 1000s.
Cascading must be limited to 4 Levels.
Video Quality, in a Coaxial Backbone configuration, uses a “240 MHz Pilot
Tone”, in the guard band between channels 26 & 27 ,from each Master GigaBUD
1000 to all levels of it’s Satellite GigaBuds. This may cause interference with
these adjacent channels. In order to prevent the potential interference, the
GigaBUD 1000 enables turning off the pilot tone after the AGC has set the signal
levels to each Satellite device. However, in the event of a power outage, the
Master devices will re-power to a “Tone On” state. The Pilot Tone, at each
Master must then be Manually turned off.
Re-mapping channels 26 & 27 to other available channels, if possible will
eliminate this potential inconvenience.

FRONT INDICATORS AND RED BUTTON ON REAR:
Initial Power-Up
All four lights indicate the System is searching for a source and whether it will be a Master or a
Satellite unit. Depending on what source is connected will provide the light sequence indicated as
shown below. When this light sequence is shown, the unit will be in “Native State”.
When there is a signal that goes into “CATV IN” port or the “FIBER IN” port the
Red
master light turns
on. The pilot tone is a unique signal sent out so that the Satellite units connected can set their levels
properly for signal balance. A
yellow
“Fourth” light indicates that the pilot tone is on and is active.
Master (CATV Wired or Fiber) Pilot
Master (CATV Wired or Fiber) Pilot
While a feed is hooked into CATV and then red button is held down the pilot tone will be switched
off. A
green
light on the fourth position indicates that the pilot tone is turned off.

Satellite (Unlocked)
The lights for this mode indicate that the unit is a Satellite unit. A blinking
amber
light means there is
a RF signal on the “Cascade In” port. Unlocked means the System is self-adjusting to set itself to the
proper levels based on distances between itself and the Master unit. Once it has settled, it will ap-
pear as 3 green lights as shown below.
Satellite (Locked)
After about a 10 seconds, the unit will lock in the parameters it has adjusted to for a balanced
System. The amber light will no longer blink and remain solid
green.
Note: If power is disrupted, the
unit will return to native state.
“GigaBUD 1000” FUNCTIONS:
Master
Satellite
While in Master and the button is held for ~5 seconds, the unit will stop broadcasting the tone and the
light will change from yellow to green. Holding the red button again will turn the tone back on. Resetting
the power from this point will return the unit to master with the tone being broadcast.
While in Satellite mode with no feed into cascade in and the button is held for ~5 seconds, the unit will
switch to a native state, all four lights will be on. When a feed is present then the red button
Function is disabled.

Some installs will require a return path for video on demand and other special features.
In the event that the system uses a DOCSIS or FSK return, it will be necessary to provide
a Bi-Directional Cascade Backbone, as shown below. In addition, Diplexer GigaBOBs will
be required at all displays. If an IP based return path is used, Bi-Directional cascading is
not required.
