Nitek DL1142 RS422 Line Driver Transmitter Up To 12,000 Feet
The Nitek DL1142 system provides RS422 data transmission
at rates up to 64K Baud for distances up to 12,000 feet (3.7Km).
The DL1142 is designed for operation over Category
2, 3, 4 or 5 unshielded twisted pair (UTP) cctv cables and standard 24 AWG telephone pairs. With this system it is unnecessary to use 18 AWG shielded pair. The unit works equally well over existing communication cables, computer network spares pairs or new cctv cable installations.
A highly balanced output design assures that the system will not interfere with other equipment on the network. The Nitek DL1142 is designed for easy connection to standard security equipment, including keyboards, matrixes, PTZ systems, access control systems, CPU units, etc.
The DL1142 RS422 line driver transmitter is a single unit that connects to twisted pair wires and RS422 via a screwless terminal block for 14 AWG to 26 AWG wires. This unit can be installed at the RS422 source or up to 4,000 feet away. The Nitek DL1142 outputs an RS422 signal that will go for an additional 12,000 feet and allows up to 32 more RS422 devices to be connected in it.
The DL1142 works with RS422, Bi-Phase and any other RS422-type signals. Two systems will provide 4-wire RS485 up to 12,000 feet. The Nitek DL1142 can also be used to split off or “Y” a signal allowing an RS422 run to go in two directions. Using several units on a longer run will support a multi-drop application of the RS422 signal.
