VPI ® II Network Connectivity> CSEX4 BoardThe CSEX4 board has two Ethernet communication channelsand four serial ports (three ports which are programmable, oneport is always the MAC – Maintenance ACcess) available witheach serial port being capable of operating up to 57.6KBPS.This board is designed such that it can also be interfaceddirectly to standard communication equipment such as FiberOptic Modems, Multiplexers, and Network Adapters. The CSEX4board can be application programmed with non-vital logic toperform man-machine interfaces, to perform, entrance-exitlogic and a multitude of other non-vital functions. The board canbe used to interface with communications bases Local ControlPanel and/or computers; or using the nonvital I/O boards it candirectly interface to discrete wired Local Control Panels.The CSEX4 board also contains a battery backed-upmemory section and clock/calendar to support the onboardDATALOGGER software used for logging both vital and nonvitalvariables. Three of the communication ports in additionto the two Ethernet ports can be utilized for external non-vitalcommunications. Each port may be configured with the sameor with a different communication protocol. The choice ofprotocols is assigned and configured in the Computer AidedApplication tools by the signal engineer. A library of almostforty communication protocols common to the railroad andtransit industry is included in the Computer Aided Applicationpackage. Typical protocols included are industry standards suchas GENISYS, Data Train, MODBUS and MCS among others.InterlockingCSEX4 Supported ProtocolsManualCompany Name/Protocol DescriptionP2346AAlgemene Sein Industrie B.V., ASI by Netherlands Spoorwegen (NS) / Lokale Controle Eenheid (LCE)P2346Bwestinghouse Brake & Signal / S2P2346DALSTOM / GRS DataTrain IVP2346EALSTOM / GRS DataTrain VIIIP2346FUnion Switch & Signal / GenisysP2346HSafetran / SCS128P2346LDTSlg Industrial Systems / LDTSP2346MModicon / Modbus RTUP2346NALSTOM / GRS DataTrain IIP2346QCanadian National RR / CN2000P2346Rge/Harmon / MCS1P2346Tbailey / S9600P2346U Advanced Train Control System Wayside Interface Unit, Specification 3 & 4P2346XHanning & Kahl / HCS-R radio control route equipmentP2346YALSTOM Signal Netherlands for PRORAIL / OPCENoneASCII©2011 Alstom Signaling Inc. www.alstomsignalingsolutions.com 43
VPI ® II Lamp Driver Output Board (LDO2)InterlockingLDO2 (LAMP DRIVER OUTPUT) BOARDThe Lamp Driver Output Board is a vital output board used to provide power to signals for both transit and railroadapplications. Using the same proven vital techniques found on other VPI vital output boards, the new LDO2 includes thefollowing features:> Current Monitoring - reads the current through the output every 200 milliseconds. This current can be compared to oneof eight different threshold levels from 0.0 to 3.25 Amps, which will turn the output off if it is not drawing the minimumrequired current. The filament checking routines enables down grading and prevents against overcurrent and shortprotection.> Cable Integrity Check - uses isolated voltage sensing at the output to determine if a potential exists across the outputwhen the output is off. A separate switch for each output can be used to select the system reaction to this event bylogging the error or dropping a vital relay.> Diagnostic Interface to VPI CPU II Board - registers all current readings and error conditions and can be read or clearedvia the CPU II board.> Board Edge User Interface - registers all current readings and error conditions and can be read or cleared alternatively viathe Board Edge User Interface.VPI LDO2 Board44CALL 800.717.4477 • FAX 585.274.8777
