1. Actual Transponder arrangements are based on the type of signal territory type and data space requirements Passive Transponders can contain information for both directions In the Up direction the train reads the first transponder in the set beginning with the 1 Transponder then the 2 Transponder and so on to 3 and 4 if present For the Down direction the train reads the Transponders in a declining sequence Ifa transponder set consists of only two transponders the train could read Transponder 2 then Transponder 1 or Transponder 1 and then 2 dependent upon direction Design and Installation The Passive PTC Transponder is a rigid compact and sealed device mounted between the rails either on or between the ties Internal electronics are mounted in a sealed compartment in a molded high impact plastic structure This ensures protection for the internal electronics in the wayside environment If the unit is faulty it can be returned to ASTS USA for repair or replacement There is no repair of internal components www ansaldo sts com RSE 1G1 p 1 Ansaldo STS USA PTC Passive Transponder and RSE 1G1 Portable Tester Programmer Rev 3 15 Transponder Transponder mm _ e Enl G cal Load _ m ae E aa UE E a pm wwe a w emer ee a 11 Feet 3 35 M 14 Feet 4 27 M Insulated Joint Typical Transponder Installation General Description PTC Transponder cont d Ea2. MHz signal in the direction of the antenna This signal triggers a modulated 4 5 MHz return signal carrying the telegram data back to the train antenna The 27 MHz signal also serves as the energy source for the Transponder s return signal The returned telegram message is then processed by the train s onboard PTC system A telegram consists of a base message package and may include one or more optional packages The total available message space is 255 bits consisting of data filler and Cyclical Redundancy Check CRC bits Examples of base messages include Transponder position along the track linking distance to the next transponder set and configuration of the group total number of transponders in the group Each Transponder set has a unique identifier encoded within the telegram data string that indicates its positioning point inside the network The use of this To order call 1 800 652 7276 unique identifier which includes the line number milepost location and track number does not permit any two Transponder sets to have the same identifier A Passive ransponder layout typically contains a minimum of two Transponders but can have as many as four The number of transponders at a given location is dependent upon the amount of information that has to be stored and uploaded to the vehicle The typical distance of the first Transponder is 14 feet from the insulated joint Remaining transponders are placed 11 feet apart

5. ch Passive Transponder is designed to be mounted flat on a tie using two bolts two washers and a mounting mat M10 or M12 bolts may be used M10 bolts are strong enough to keep the Transponder in place but M12 bolts are recommended in order to get a greater pressure surface at the fastening point If M10 bolts are used a tube is used to fill the gap between the bolt and the transponder s mounting hole This tube is installed in order to ensure that the transponder will stay in its position If the transponder bolts cannot be fastened into the tie a mounting bracket can be used The Transponder can be oriented in the transverse preferred or longitudinal position Longitudinal mounting gives a little longer contact area General Description Tester Programmer The portable Transponder Tester Programmer is used to program the Passive PTC Transponder and to read the stored telegram It is powered by a rechargeable 1 2 Ah 12V sealed lead acid battery During programming the Transponder is connected to a PC running ASTS USA s TranEdit software Control panel devices include an LCD alphanumeric display buttons LEDs and power ON OFF switch In addition the control panel incorporates three connectors that link the Tester to the programming PC battery charger and the Transponder Each time the Transponder Tester Programmer is turned on a self test sequence starts If no failure is detected the sequence ends with a battery status
