The Virtual Cabinet Model TVC-3800 is a complete diagnostic and testing toolkit for all devices that communicate on the SDLC bus in the ATC or TS2 Cabinets. The Virtual Cabinet connects to a Windows based computer with a USB connection1. By using an intuitive graphical software interface, The Virtual Cabinet can be configured to emulate a cabinet controller or the cabinet SIU/BIU devices.
The Virtual Cabinet can operate in four different modes:
1) TS2 Cabinet Emulator: Connects to SDLC Port 1 of a NEMA TS2 standard controller unit. The Virtual Cabinet emulates the remaining cabinet components.
2) ATC Cabinet Emulator: Connects to SDLC Port C12S (SB#1) of an ATC 5301 standard controller unit. The Virtual Cabinet emulates the remaining cabinet components.
3) TS2 Controller Emulator: Connects to SDLC Port 1 of a BIU type device. The Virtual Cabinet emulates the controller.
4) ATC Controller Emulator: Connects to SDLC SB#1 of an SIU type device. The Virtual Cabinet emulates the controller.
Choose from included intersection layouts, construct your own intersection or import a satellite/aerial view image and add signals. Add loops, calls, and train tracks with preempt and activate them to verify the sequence. Intersection layouts can be saved to recall later as needed.
The TS2 Frame Grabber allows technicians to graphically view, sort, and analyze all SDLC frames that were transmitted in the 30 minute period leading up to the intersection going into "flash".
The TS2 Frame Grabber connects to the SDLC bus in any NEMA TS2 cabinet and continually records all frames transmitted between the controller, BIUs, MMU, and other auxiliary devices. The frames are stored in a circular buffer that will hold approximately 20 - 30 minutes worth of data. Anytime the MMU reports that the intersection is in "flash", the frames are automatically stored to a removable memory key. A technician may then remove the key and insert it into a reader connected to a PC. Using the FrameView software application, the frames may be viewed in an easy to understand graphical format.
Reviewing the hundreds of thousands of frames that may be transmitted over a 30 minute period would be a nearly impossible task. This is where the power of the FrameView software application becomes quickly evident. The software groups the frames into one second time periods and displays them on a time line. Any time period that contains frames which meet certain user settable criteria will be clearly marked with a "flag". The user can simply click on the flagged area and then expand the frame to view a graphical translation of the data with any alarms, or warnings clearly displayed in red. The following conditions are examples of events that may be "flagged" : corrupted data, missing response, incorrect response, incorrect address, MMU diagnostic failure, dual display, conflict, red failure, DC voltage failures, clearance faults
Supports Flashing Yellow Arrow functions
The Graphical Intersection Interface allows the user to choose from existing layouts or to draw their own intersection layout.
