I. Purpose The Short Line Technologies (“SLT”) model SLT-100 reads AEI (Automatic Equipment Identification) RFID Tags for any rolling railroad stock These tags comply with the requirements of the Association of the American Railroads (“AAR”) Standard S-918. II. Functionality Through the use of the most modern technology, maximum allowable effective radiated power and innovative error correcting software, the SLT-100 offers a significant improvement in the percentage of AEI tags read correctly. In addition to its core functionality of reading the AEI Tags that are mounted on passing rolling railroad stock, the SLT-100 provides two additional key features: 1. Direction Sensing – Two 24 GHz Doppler radar sensors, one on each side of the SLT-100 enclosure, sense the presence and direction of railcar motion on either side of unit. By accurately sensing direction of the train, whose AEI tags are being read, the cost of a 2 nd Tag Reader on the opposite side of the track is avoided. 2. Wireless Communications – Radio communications between the SLT-100 and its host computer eliminates the need for lengthy and expensive communications cable installation. The built-in data radio modem provides reliable communications to a host computer equipped with a companion modem. This offers a typical range of about 0.6 mile. By placing a Booster-Bridge within approximately 0.6 miles of the SLT-100, total coverage distance of as great as 30 miles is possible. III. Installation The SLT-100 is designed for simple, inexpensive installation. 1. Mounting -- The SLT-100 should be mounted 8 to12 feet from the rail. Usually a 2 to 3 inch steel pipe supports the unit, however it may be secured to any convenient object that is sturdy enough to hold the SLT-100 rigid even when a train is passing. The mounting is two 12 inch wide Unistrut™ 1 ⅝” on the rear of the unit. The SLT-100 comes with a set of clamps for a 2 ½ “ pipe. The Unistrut 1 catalog offers a vast array of other mounting options to satisfy any mounting requirement. 1 Unistrut 4205 Elizabeth • Wayne, MI 48184 Tel: 800 521-7730 • Fax: 734-721-4106 www.unistrut.com 2. Height -- The mounting height of the SLT-100 Tag Reader should place the center of the box about 3 feet above the rail. The front of the enclosure should be parallel to the rails. [ does this say what you want it to?] 3. Power – The SLT-100 requires approximately 40 watts of standard 117 VAC, 60 Hz power. All applicable electrical code requirements should be adhered to. The power connection is made through a mating connector that uses screw terminals to terminate the power wires. IV. Wireless Communications There are three options for communicating with the SLT-100: short range, long range, and mesh. In the course of this discussion it is important to bear in mind that coverage distances provided are generalizations, based on average conditions of terrain, ground cover, and levels of electrical noise and interference. The only way to be certain that a specific path will work is to conduct a site survey. Please contact the factory if you wish to arrange for such a study. 1. Short Range – A distance of approximately (see the note above) 0.6 miles may be realized using the 2.4 GHz modem built into the SLT-100. At the receiveing [should this be receiver or receiving?] end a 2.4 GHz modem connects to the USB port of the controlling computer. A laptop computer with this radio modem is also used for the initial setup. 2. Long Range – For distances up to 30 miles (under ideal conditions), a frequency hopped 900 MHz link is used. To establish this link, a 2.4 GHz …
