LX MAINFRAMESThe LX Series Mainframes are 19" rack mounting chassis, 3.5"high and 15.6" deep with power supplies and motherboardsthat hold up to 16 Switch and Display Modules and one ControlModule. Signal connectors are located at the unit's rear paneland LED display is visible through the front panel.The following Mainframes are standard:LX-1The LX Series are high reliability, low cost, versatile Switching Systems. A modular design concept isused, and interchangeable Control Modules, Switch Modules and Display Modules can be assembledinto Matrices, Multiplexers or Individual Switch Point configurations. All chassis have full front panelLED displays, and Status Feedback from all switches is provided. A variety of switch modules areoffered, including those designed to handle the following signals: Coaxial RF, Low Level with a DCoffset less than 1 microvolt, High Voltages to 1500 volts, and High Current to 8 amps.Control Modules available are 10100Base-T Ethernet LAN, IEEE488 Bus, RS232 Serial and TTLParallel Port. USB and Manual Controls are optionally available.LXA GENERAL PURPOSEThese are the most versatile units, accepting any of the LXSeries Switch Modules and capable of furnishing Multiplexers, Matrices or Individual Switches as needed.LXB MATRICESThese mainframes hold the LXB Series Switch Modules andfurnish several prewired Matrix configurations.LX EXPANSION CHASSISThese units have the same motherboards as the Mainframes butdo not have built-in power supplies or Control Modules. Theyare powered and controlled from a single MESA Control Mainframeas described in the MESA Bulletin. Larger configurationscan be created from up to 16 Expansion Chassis, and differentproduct series can be combined to supply a complete systemfor switching a variety of signals.LX-W WIRED UNITSAll Mainframes and Expansion Chassis can be supplied in 16"deep chassis with modules wired out to user specified connectors.Please contact our Applications Engineers for moreinformation.SWITCH MODULESThere are two basic switch module series: the LX8 Series andLXB Series. All modules have signal connectors accessed atthe chassis rear panel.LX8 SERIESThese modules are used in the LXA Mainframes and includethe following:LX8G2 Switch Modules are built with 8 two pole relays andhave signal inputs and outputs arranged so that they can bewired to supply several matrix configurations.LX8G1P Switch Modules are built with 8 single pole Type PPower Relays. These are designed for high power and currentapplications and have signal connectors that can be wired toprovide several matrix configurations.LX8K Switch Modules have 8 Normally Open single pole relayswith inputs and outputs wired to a signal connector.LX8OD Driver Modules have 8 optoisolated Output Driversand are used to drive external logic or electrical loads.LX8ID Input Detection Modules have 8 optoisolated InputDetectors that are capable of sensing DC or AC voltage levels.LXB SERIESThese Switch Modules are used in the LXB Matrices and includethe following:LXB2(1x4) Switch Modules have 8 two pole relays arrangedas two 1x4 matrices.LXB4(1x2) Switch Modules have 8 two pole relays arrangedas four 1x2 matrices.
