Kramer FC-50 overview

  • 1Description

Designed and built with both facility installation pundits and presentation/multimedia enthusiasts in mind, the Kramer FC-50 RS-232 Extender offers twisted pair (RJ-45) signal conversion from an RS-232 serial control (9-pin D-Sub) port. It's capable of sending the converted signal over a 3280' range to an additional FC-50 extender that converts the twisted pair signal back into an RS-232 signal. It features Mode Selection for unit/PC control connectivity, Mode LED Indicator, and Cross/Straight Selection for specific configuration between the unit and the controlled device. It's compatible shielded or unshielded twisted pair (STP/UTP) cabling such as standard CAT5 (Ethernet network cable).

In addition to its high-quality RS-232 to twisted pair transmission capability, it features Power Connect System which requires only (1) powered unit in a connected system; and its data mode Baud rate offers data rates up to 115.2Kbps. With its superb signal reliability and twisted pair signal transmission technology, the Kramer FC-50 is ideal for long distance RS-232 control often required by broadcast studios, educational, security and military installations.

Note: This unit must be used in conjunction with an additional FC-50 to achieve a complete solution.

Twisted Pair (RJ-45) Signal Transmission
Twisted pair (RJ-45) cabling uses 2 conductors (forward and return) that are twisted together in a specific fashion (pitch/twist rate per meter) to cancel out electromagnetic interference and crosstalk (noise) from external sources and its environment.
Connectivity Ports
The FC-50 features an RS-232 (9-pin D-sub) serial control port and an RJ-45 (CAT5) twisted pair jack.
Mode Selections
This unit offers the ability to select whether the 9-pin D-sub is connected to a PC or the device being controlled by the PC (2-units are required). In addition, it features Crossed/Straight Selection between the unit and the controlled device.
Power Connect System
Within transmitter/receiver system, only one unit requires power when connected devices are within a 150' (50 m) range of each other; 12VDC power is distributed through the CAT5 cable.
Large Venue Solution
The FC-50 is an ideal solution for schools, transportation hubs, hospitals, financial institutions, commercial/retail installations, virtually any large venue that requires reliable long-distance RS-232 serial control through twisted pair cabling (3280' system range).
CAT5 Cabling
This unit will accept UTP (unshielded twisted pair) or STP (shielded twisted pair) CAT5 cabling.
Optional Mounting
Aside from its rugged chassis, its standalone compact design belongs to the Kramer TOOLs family of products; 4 units can be rack mounted side-by-side in a 1U rack space with the optional RK-1 universal rack adapter.
