Modular Extender System for transmission up to 12,000 feet
(3,657 meters)
   
   
Revision Number:
020503

Description:
The DL2105 system provides data transmission for RS232 signals at rates up to 64K Baud for distances up to 12,000 feet (3,657 meters).

The DL2105 is designed for operation over Category 2, 3, 4 or 5 unshielded twisted pair (UTP) cables and standard 24 AWG telephone pairs. With this system it is unnecessary to use 18 AWG shielded pairs. The system works equally well over existing communication cables, computer network spare pairs or new cable installations. A highly balanced output design assures that the system will not interfere with other equipment on the network.

The DL2105 units are designed for easy connection to standard security equipment, including keyboards, matrixes, P/T/Z systems, access control systems, CPU units, etc.

The DL2105 is a two unit system that connects using twisted pair from transmitter to receiver to extend RS232 up to 12,000 feet (3,657 meters). All connections are via a screwless terminal block that accepts wire sizes from 14 AWG to 26 AWG. The system works with all Baud rates up to 64K. It is possible to daisy-chain up to 24 receiver units (extra receivers must be ordered separately) from a single transmitter.

The system includes a transmitter, receiver and power supplies. Some of the typical applications include remote keyboard control of multiplexers and matrix systems and use in access control systems.

Features:

  • EIA RS232 standard inputs and outputs
  • Data speeds of 64K baud
  • Built-in surge suppression
  • Balanced communication output can be run in the same cable with telephone, video and other computer signals
  • Screwless terminal blocks allow easy connection to any wire type from 14 AWG to 26 AWG

Wire and Cable Recommendations

All Nitek data transmission systems are designed for use with unshielded twisted pair (UTP) wiring. The systems will operate over wire gauges from 24 AWG through 12 AWG. Category 2, 3, 4 or 5 cable may be used. Tndividually shielded pairs should be avoided, as they drastically reduce the operating range of the systems. Multi-pair cable with an overall
shield is acceptable. The data communication signals can be sent in the same communication cable coexistent with telephone, computer, control signals, power voltages and video signals (where local codes allow). While they 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.
