Please refer to the appropriate section of this manual for more information on specific questions and displays The LCD type of display used in the Apollo consumes very little power thereby minimizing battery drain during setup and monitoring procedures To further save battery power the Apollo will turn off power to the display when data collection is active and the display is not being used Road dust will inevitably cover the display from time to time and the display will need to be brushed off When cleaning the display it is best to attempt blowing off as much dust as possible before wiping the surface with a soft damp cloth This method limits the chances of scratches being caused by the abrasive found in the dust ll c SERIAL PORT The serial port is used for the retrieval of traffic data that has been collected by the Apollo All serial devices are connected to the Apollo through the DB 9 Serial Port plug located on the lower right side of the face panel Note that the Apollo can be completely programmed and operated from the serial port a PC USB to Serial adapter may be needed for newer PC s The serial port supports 19200 8N1 Communication The retrieval of data must be done through the serial port and the method of transfer is 1K XMODEM with CRC error checking An automatic switch to 128 Byte XMODEM transfer occurs when the system gets 10 or more errors indicating a noisy line Data will transfer faster with smaller b

16. the following D2 ss ee DI Apoll One wave traveling down and one weaker wave returning They will of course collide into each other at some point in the road tube weakening both waves so that the second wave is too weak to register as an axle strike The question then becomes if this is causing missed axles why does a shorter road tube work better If you take a 30 road tube stretch it 50 Sound Wave D will start at about the 24 mark and therefore will take only 21ms to reach the airswitch Similarity Sound Wave D will only take 21ms to return to the starting point at the 24 mark This makes the total time only 42ms for the first Sound Wave D to strike the airswitch and return to the starting point This time is BEFORE the 56ms time it takes for the next axle to hit Therefore the first Sound Wave D is past the point of origin and cannot interfere with the next axle strike In summary you are better off using shorter road tubes for faster speed vehicles You are also better off using shorter road tubes for vehicles which have closer axle spacings such as truck tandem axles To minimize missing axles and maximize accuracy we suggest using the following road tube lengths Speed Road Tube Length 0 25mph 60 ft 26 35mph 50 ft 36 45mph 40 ft 46 30 ft While a shorter road tube at faster speeds is always more accurate we do not suggest using road tubes shorter than 30 due to the potential damage to an ai
