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

The TS2 Virtual Cabinet (TVC-3500) provides the full emulation of a NEMA TS 2 standard cabinet. It connects to an SDLC port (Port 1) of a NEMA TS 2 standard Controller Unit (controller). TVC-3500 receives SDLC frames from the controller, processes those frames and sends responses back to the controller. It also runs a full simulation of TF BIUs 1-4 (Terminals and Facilities), DR BIUs 1-4 (Detector Rack BIU), and an MMU.

Through the interface software (TS2 Virtual Cabinet Interface), the user can change inputs and monitor outputs of the TF BIUs, and simulate detector calls. This allows the user to monitor the controller's "reaction" to various inputs such as emergency vehicle preempt call, pedestrian call on a particular phase or an actuation of any detector call.

The software will also automatically enable inputs/outputs for those BIUs that are programmed in the controller and show which BIUs should be present in the cabinet. This provides a visual presentation of how the controller is setup and what inputs/outputs are available for the given controller configuration.

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.
