![]() Third, if a question mark or yellow error icon is displayed in the "PORTS (COM&LPT)" or "DEVICES/USB<->Serial" headings, this is an indication that no drivers are currently installed for the GPS receiver. Second, from your START button, open CONTROL PANEL > SYSTEM > HARDWARE > DEVICE MANAGER. First, connect the GPS receiver to your USB port. Ģ3.) Q: My device is not being detected by my software using Windows platform. NOTE: If your map software (such as Street Atlas 5) requires data sentence GGA, and your GPS (such as the Magellan 3000) does not output GGA, then they will NOT work together. Ģ2.) Q: Will my receiver support older NMEA standards? Ģ2.) A: Yes, NMEA 2.0 is backwards compatible with older versions of the protocol. ġ9.) Q: Does the current USB driver support Mac OS X Snow Leopard? Ģ1.) A: The voltage ratings are set to 5VDC. In short, the receiver requires GPS data to update these parameters. It can explain why incorrect date display at first. Only after new GPS signals are received, correct data will display. If backed battery is inactive, default parameters will display. When you re-start GPS, last stored data display at first if backed battery is still active. After a long period of time(about 4 hours, depend on different products) GPS is power off, backed battery will run out and last stored data will lose. ![]() It can help us to achieve maximum acquisition performance. When you power down GPS, backed battery will keep the last data. Is SiRF Binary Protocol a permanent configuration? ġ8.) Q:What can I do to prevent my device from having GRMC NMEA time stamp data problem? ġ8.) A: There is backed battery for SRAM and RTC (Real-Time Clock) to keep last stored position, date ,time, satellite data. Greater the cable length, less sensitivity quality. ġ6.) Q: What is the recommended maximum cable length for wired GPS devices? USB? Serial? ġ6.) A: We recommend 1.5m (4.92 ft.)/ 3m (9.84 ft.) cable length for USB/ Serial GPS device. If you are unsure about whether your vehicle has one of these types of windshields, contact your dealer and request more information. Customers with these types of windshields must use an exterior GPS antenna for improved results for GPS applications. ġ4.) Q: Why am I not getting any or very weak GPS signals even though my GPS receiver is directly under the windshield glass? ġ4.) A: Certain vehicles may be equipped with special windshields that contain metal in the glass that prevents GPS and RF signals from being received properly. What can I do to correct this? ġ3.) A: Under GPSInfo application select a ìCold Startî to reset receiverís registers. Environment: highway, no high trees and buildings. Sometimes it took as long as 7-9 minutes (solid green LED). ġ3.) Q: Lately it takes too long to lock the satellites. ![]() Then the receiver will revert back to its original default settings. Note, custom settings are temporary until the receiver has exhausted both the internal Super-Cap. ġ2.) Q: Can I reconfigure receiver's NMEA data? If so, what program? ġ2.) A: Yes. ġ1.) Q: Can I reconfigure receiver's Baud-Rate? If so, what program? ġ1.) A: Yes. ħ.) A: GGA(1sec), GSA(5sec), GSV(5sec), RMC(1sec) Ĩ.) Q: What is the output format for this receiver? Ĩ.) A: Output format: GGA(1sec), GSA(5sec), GSV(5sec), RMC(1sec),( VTG and GLL are optional) ĩ.) Q: How many satellites are needed for 3-D positioning? ġ0.) Q: Can I reconfigure receiver? If so, what program? ġ0.) A: Yes. ģ.) Q: How important is having WAAS enabled on your GPS receiver? ģ.) A: It provides better accuracy up to 3m Ĥ.) Q: What satellite identification number is used for WAAS and EGNOS? Ĥ.) A: Satellite #33 (AoRE) is for EGNOS, Satellite #35 (AoRW) is for WAAS, and it has been suggested that Satellite #41 (PoR) will be used to indicate that data is being received from the Japanese MSAS system. 1.) Q: What chipset is my BU-353-S4 using? Ģ.) A: Yes, the BU-353-S4 serial GPS receiver is WAAS enabled by default, it was sold by USGlobalSat, Inc and its Authorized Dealers. ![]()
