The TT560 is designed for operation over category
2, 3, 4 or 5 twisted pair cable. The units work equally well
over existing communication and computer network spare
pairs, or new cable installations. A highly balanced transmitter
output design assures that the system will not interfere with other equipment on the network. In addition, the transmitter
is virtually impervious to ground loop and has high
immunity to noise and interence from other signals. Built-in
surge protection is standard.
A dip switch on the unit provides precise adjustment
of gain and frequency compensation, allowing the system
to be "fine-tuned" for any cable.
The TT560 transmitter comes with a power supply
and is designed to work with both the TR560 standard receiver
and TR560x2 Modular receiver. Complete systems
including transmitters, receivers and power supplies are
available. Refer to the Ordering Information chart (reverse
side) for system information.
Features
|
- Active electronics compensate for frequency and
level loss
- Built-in protection from power surge, transients,
static or other electrical interference
- High resolution color or monochrome video
- Complete immunity to ground loop; video and AC can
be run in a common raceway, where allowed
- Video can be run in the same cable with telephone
and computer signals
- Weather resistant design
- Easy to install

Applications
|
- College Campuses - using existing communication cables saves time and money
- High Rise Buildings - between floors. through punchdown blocks
- Detention Facilities - using existing communication wiring
- High Voltage Facilities - high immunity to AC power interference
- Parking Garages - where running coax is difficult to impossible
- Remote Gates - can be run in same cable with audio and gate control

Wire and Cable Recommendations
Twisted Sender is recommended for use with unshielded twisted pair (UTP) wiring. The systems will operate over wire gauges from 26AWG through 12AWG but are optimized for 24AWG. Category 2, 3, 4 or 5 cable may be used. Individually shielded pairs should be avoided, as they drastically reduce the operating range of the systems. Multi-pair cable with an overall shield is acceptable. Video can be operated in the same communication cable coexistent with telephone, computer, control signals, power voltages and other video signals. While video may be routed through telephone punch down block terminals, any bridge-taps, also called T-taps and any resistive, capacitive or inductive devices MUST BE removed from the pair.
