Info

The top two lines on the monitor feature the largest characters, and indicate the next two trains coming into the station, especially important for a commuter rail system. Below that, any other kind of information can be displayed, such as for emergency or weather details. YOUR TOTAL IR SOLUTION • Ideal for courtrooms, boardrooms, theatres, and city councils • Secure interference free solutions two-inch-high text comprised of 20 characters, in red only. Although it was a reliable method of communication, the system had exceeded its lifespan and had to be replaced and upgraded. “The new system built around an LCD screen would allow VRE to present [train information], both graphically and in text. They can vary the text format and the font size, change colors and have a lot more flexibility than the previous [LED] system,” he said. Keelor explained that the 40-inch NEC LCD screens provide a much larger viewing area, going from only one line of 20 characters on an LED to as much as six lines comprised of 20 to 24 characters via an LCD. The top third of the LCD display is reserved for the next two trains and their statuses, with the earliest train on top and the following train on the bottom. So, now the customers can see what’s happening two trains out. And, in the event more information is needed, the screen can rotate to additional frames. However, Keelor cautioned, “You don’t want to put too many frames on because people don’t want to sit there and wait: (viz) turn the frame, turn the page, wait; turn the frame, turn the page (etc.).” Woolner gave an example of VRE’s inner stations “where we have both Don’t miss a single sound. • Any size project • Mono or Stereo – easy to program • 1-32 Channels • Customizable systems • Standard off the shelf batteries • Programmable options • Simple to specify, install, maintain and use • Receivers offer auto shutoff Free no obligation demonstration +1 800.330.0891 North America sales@listentech.com www.listentech.com Upgrading To TRIP II, Thanks To Rich Doyle VRE’s Woolner pointed out that Turnkey Technology president Rich Doyle was instrumental to the upgrade because the railway had an existing TRIP system. In turn, Doyle made TRIP II and modified the system’s program source code in order to identify the messages coming from TRIP for IDS’ use. “IDS was then able to pull those off and push the message out into the sign [display] and also give us a status that confirmed everything was working and reporting back to TRIP again. “Doyle was the interface between IDS and our TRIP system. He’s the one who made it work for us. TRIP is one key area we were very concerned about. If we didn’t get that right, we wouldn’t be able to make the system work.” 54 Sound & Communications www.soundandcommunications.com
