231: Decoder Installation/OperationFigure 1.1 System overview TransponderDetection loopPowerHeadphoneDecoderComputer
451.1 Installation of the decoderThe decoder is a precision instrument. Therefore please handle it with care and keep the decoder out of direct sunlight and avoid high humidity. Take special precautions in case of thunderstorms by disconnecting all cables (coax, Ethernet and mains) from the decoder. Nearby lightning strikes can damage the decoder when these cables are connected.Figure 1.2 Connections of the decoderHow to connecta) The detection loop: Connect the supplied 75 Ohm double-shielded coax cable to the decoder.b) The auxiliary port: This port can be used to connect a photocell, external start pulse or a sync pulse. For more information on how to connect these devices, contact your nearest AMB i.t. ofce.c) The serial port: This port can be used to connect the decoder with the computer with a RS232 cable.d) The network: Connect the network cable between the decoder and the network connection port of the computer.e) Power: Connect the 12 VDC adapter to the decoder and mains. Since a power interruption will result in a failure of the timing and scoring system, connecting the 12 VDC adapter to mains through a UPS (Uninterruptible Power Supply) is recommended. f) The headphone: Connect it on the front side of the decoder. A beep will sound for every passing transponder, which provides an easy check for proper operation of the decoder and the transponders on the track.a) b) c) d) e)
451.2 Operating the decoderThe decoder is not equipped with an on/off switch, therefore connecting the decoder to the mains will switch it on and will enable timing of transponder passings after approximately 15 seconds. With each detection of a transponder, a beep will sound in the headphone and received transponder information is shown on the decoder display. 1.2.1 Noise levelThe decoder determines the average background noise. The noise (and signal strength) has a range of 0 to 255 points. Noise level, as shown by the AMB i.t. timing software and also on the decoder screen, should best not exceed 40 points. If the noise level is higher, the received transponder signal strength should be 60 points above noise level to ensure proper functioning of the system. So if the transponder received signal strength is 120 points, the noise should not exceed 60 points.1.2.2 Signal strengthTransponder signal strength, as shown by the AMB i.t. timing software, should preferably be above 100 points and should at least be 60 points higher than the indicated background noise. The closer a transponder is to the track the higher the signal strength. A higher transponder signal strength gives a higher immunity against outside interference.1.2.3 Number of hitsThe number of hits, as shown by the AMB i.t. timing software, is an indication of the number of repeated transponder signal receipts during a passing. Hit-rate varies with the speed of a passing transponder. Slower passings yield higher hit counts. The minimum number of hits should not be below 10 points.

891.3.1 MENU: GeneralWithin the general menu you can choose/see:- Clear passings: clears the passings in the ash memory.- Timeline: description of the loop name.Occasionally needed for the timing software.- Beep: to choose the tone of the beep.- Loop trigger: optional for future developments.- First contact: when switched on the decoder will send a record without a time stamp a soon as the transponder is detected. This is intended to allow TV graphics applications to already display a name, while the passing time is not known yet (works with P3 protocol only).- Protocol RS232: This is used to select the protocol on the RS232 interface. There are 3 options:Enhanced: This protocol is here only for compatibility reasons. Not all features are available via this protocol.P3: If you are a software developer this is the preferred protocol to use. This protocol is also used for software like ‘Racewave’ and ‘Orbits’. Remote:Allows the host computer to select the protocol by using a command.- Contrast: contrast of the display.Here you can adjust the contrast settings.- Factory defaults: reset to the factory defaults.You can reset the settings of the decoder to the initial settings. - Firmware: software running inside the decoderWhen you update the rmware in your decoder, the decoder will retain the current version of the rmware. With the switch rmware option you are always able to revert back to the previous version.
10111.3.2 MENU: NetPlease leave the decoder in the automatic menu if you are not familiar with network basics.Within the Net menu you can choose/see:- Automatic: to automatically determine the IP address of the decoder.If your decoder is placed in a network and you select automatic “on” the decoder will rst try via the DHCP server (DHCP = Dynamic Host Conguration Protocol) to get an IP address which is in the range of the network. Please note that it can take around 60 sec. to obtain the settings via DHCP. If a DHCP server is not found, the decoder will use an IP address via APIPA (Automatic Private IP Addressing)- IP address: IP address of your decoderAn identier for a computer or device on a TCP/IP network. - Subnet mask: A mask used to determine what subnet an IP address belongs to.- Gateway: A node on a network that serves as an entrance to another network.- DNS: Short for Domain Name System (or Service or Server), an Internet service that translates domain names into IP addresses. Gateway and DNS are both used to set up the decoder for Mylaps live.1.3.3 MENU: TimingWithin the timing menu you can chooose/see: - Sports: There are many parameters which may inuence timing performance. With the sport setting the decoder uses some pre-dened parameters optimized for a certain type of sport / transponder placement.

Please visit www.mylaps.com for more information about nding all your race results online.Note : For using mylaps live you need a functioning internet connection. Also the DNS server and gateway setting have to be correctly congured (see menu ‘network’).
1213Appendix A : FAQsA1: Transponder is not being detectedA few of the transponders are not being detected.If this is the case, the problem is most likely related to the individual transponder or the positioning of the transponder. - Check the mounting position of the transponder, for more information check your transponder manual.None of the transponders are being detected. If this is the case, the problem is most likely related to the detection loop, decoder, timing computer or cabling. Please take the following steps:- Check if a beep is heard in the headphone, or of the loop in the display changes to black during a transponder passing. If this is working, but nothing appears on the computer screen, check the cabling between the decoder and the computer.- Check the coax cable by measuring the resistance (with multimeter) between the centre pin and the outside of the BNC connector. The reading should be approximately 150 kOhm after 30 seconds. If not, the coax has to be replaced.- Check the loop wire by cutting the loop wires from the connection box and measuring the resistance between the loop wires in the track. The reading should be approximately 220 Ohm. If this is not the case, the loop has to be replaced. When (re)connecting the loopwires to the connection box please solder with proper connections (for more information please check your system installation manual).
1415A2: Noise levelWhat if my background noise is higher than 40 points?An increased background noise is an indication of a higher interference level picked up by the system. Every ve seconds a background noise measurement is performed by the decoder and sent to the computer. The noise level should be as low as possible, but as long as the received signal from the transponders is 60 points higher then the noise level detection will be reliable. If the noise level is higher than 70 there is most likely something wrong with the installation.Possible causes of high background noise levels:- When the detection loop is damaged, a uctuation in noise level will be noticeable, especially in wet conditions. If this is the case, please check the loop wire and coax for cuts or breakage.- Electrical equipment too close (<3 m) to the loop or coax cable.- Using a generator with a poor ground connection- Use of DC/AC converter for AC power.- Poor connections between the detection loop and the coax cable.- BNC connector incorrectly tted to the coax cable.- Poor ground connection of the AC power. If this is the case, ground the decoder by connecting the outside the BNC connectors on the decoder to a piece of metal (copper rod or tube) that goes into the ground. A3: Signal strengthWhat if the received signal strength is below 100 points?- If the signal strength is lower than 100 points, please check the position of the transponder.- If the signal strength is uctuating heavily in combination with high noise levels, check the quality of the loop installation and coax cables.
