The J & K-Series is Control Microsystems' premier line of spread-spectrum, unlicensed data radios. With two sub-series to choose from, the Ethernet-based J-Series and serial-based K-series, J & K series pack a lot into one compact package. The J & K Series operate in the 900MHz and 2.4GHz frequency ranges and may be configured as an advanced remote, full-feature repeater/bridge or in a redundant hot stand-by system with select E-Series products. Installation is a snap with several mounting options, including din-rail, stand-offs, integrated SOLARPack and panel.

The J-Series is the first Trio product to offer "IP over Ethernet" technology and an Embedded HTML web server, providing comprehensive Network Management and Remote Diagnostics capabilities; all contained in a sealed, hard shell metal package. The K-Series data radios are designed for the high speed serial data transfer requirements of any modern SCADA system and are available in a sealed hard shell metal package, a panel mounted metal shell package or a board-only variant.

Many innovative features have been incorporated into the J & K-Series, including multiple data stream support, channel sharing and network bridging, ensuring that even the most challenging of SCADA systems will benefit from optimized data transmission and bandwidth utilization.

For added convenience and flexibility, the J & K-Series has dual antenna connections, an internal multiplexer and a system port providing system-wide network management access and interruption-free 'hot' user configuration. The single site, multi-master synchronization feature allows for the simultaneous transmission of data, with no TX and RX interference, thereby increasing system capacity considerably over similar competitor products.

The J & K Series boasts true high-speed data rates of up to 256kbps, low power consumption with a dynamic sleep mode and a wide operating temperature range of -40º to +70ºC (-40º to 158ºF).
