Description:
The TR515x4 is
designed for use with the modular rack system.
The system holds up to ten (10) Modular cards in any
combination, using the RK400 card cage (not included).
This modular “plug-in” feature allows the
system to be custom configured for each application
and provides easy expandability.
The TR515x4 is designed for operation
over Category 2, 3, 4 or 5 twisted pair cable. The
system works 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. Advanced receiver electronics provide
complete immunity from ground loop, hum and noise
to produce maximum video quality with minimum loss.
A dip switch on the receiver unit provides incremental adjustment of gain and frequency compensation to allow the system to be “fine-tuned” for an existing cable. This unique feature provides adjustment for optimum performance
over the entire operating range and also allows
cable length to be estimated with a wide safety
margin. The TR515x4 includes only the receiver card. See Ordering Information for transmitter units. |
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 code allows
- Video detect LED’s for each receiver
- RJ45 or push terminals for easy connection

Wire and Cable Recommendations
Twisted Sender is recommended for use with unshielded
twisted pair (UTP) wiring. The systems will operate over wire
gauges from 26 AWG through 12 AWG but are optimized for
24 AWG. 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.
For more specific information regarding wire types, gauges and proper installation techniques, please call (800) 528-4343 for technical assistance. More information is also available on the CCTV System Design Guide Sheet.
