Installation for Mac 1. Put the driver CD into your computer. 2. Explore the CD and double click on the folder that is named Mac Driver. Double click “MacOS X Universal Binary Driver” folder. Then double click “PL2303_1.2.1r2.dmg”. 3. In the PL2303 Driver window, double click PL2303_1.2.1. 4. In the “Install Prolific USB to Serial Cable Driver V1.2.1 for Mac OSX” window, click continue. 5. In the “Select a Destination” window, click continue. 6. In the Easy Installation “Macintosh HD” window, click Install. You may type password to permit Mac install the driver. 7. In the “Installing this software requires you to restart your computer when the installation is done. Are you sure you want to install the software now?” window, click continue installation. 8. Click restart. 9. The driver will now be installed.
1. I lost the Zenstar Driver CD. Where can I get the driver & programs? 4. What programs does the Zenstar GPS interface with? 5. Why does my Zenstar III GPS receiver need a long time to get WAAS satellite signal (DGPS fix)? If you have more questions, please call 250-390-1671 for assistance, or send us an email link to Contact Us.
1. I lost the Zenstar Driver CD. Where can I get the driver & programs? Please click http://www.Zenstargps.com/download.htm to download them. 2. I have everything installed correctly. The indicator light is on, but the light is not flashing and I do not appear to have a signal. The GPS requires a clear view of the sky. If you are indoors, or have the GPS located under a roof, overhang or dense foliage it is more difficult for the GPS to “see” the satellites. This impairs your signal. Move the GPS to an open spot. Fixing your position may take several minutes. Especially when using the Zenstar for the first time. After an extended of period of dormancy a longer time may be necessary to acquire a fix. This is because the internal battery requires charging before the GPS can obtain a good signal. The Zenstar is a Global Positioning System receiver. Above us constantly, positioning satellites circle the earth sending signal information. GPS receivers process the signals and calculate their exact location by measuring the time difference from the satellites to determine accurate distances from the satellites. These points are triangulated to arrive at the location. A GPS receiver must have a clear view of the sky because it operates by line of sight with the satellites. A minimum of three satellites must be locked on to determine position and provide tracking ability. Your Zenstar communicates with your computer software with NMEA 0183 Interface Standard. This defines electrical signal requirements, data transmission protocol and time, and specific sentence formats. The software translates the GPS information to display your location on a geo-referenced chart. 4. What programs does the Zenstar GPS interface with? The Zenstar GPS is designed to work with your computer and is compatible with all navigation software that requires a GPS with NMEA output. The following list is a sample of some of the programs that interface with the Zenstar GPS. Marine Navigation Software - Maptech
-
Cap'n - Rose Point - Ozi Explorer
-
GPSNavX
Street Navigation Software - Microsoft Streets & Trips - Destinator - Co-Pilot Travroute - Delorme Street Atlas
Terrain Navigation Software - Maptech Terrain Navigator - Ozi Explorer - Memory Map Navigator 5. Why does my Zenstar III GPS receiver need a long time to get WAAS satellite signal (DGPS fix)? WAAS PRN 122 and 134 satellites (in NMEA that is 35 and 47) were removed from service and replaced by PRNs 135 and 138 satellites (NMEA 48 and 51) back in July, 2007. Zenstar III GPS receiver has a search list in the code that determines which satellites it looks for, and if it can't find one, then goes through the rest of the list in order. The receiver previously had 122 and 134 at the top of its list. 135 and 138 were near the bottom of the list. So it takes time searching for 122 and then 134. Once it has exhausted the search with no results, the old versions firmware starts going through the entire list. It takes quite a while to find 135 or 138. In order to get a quick WAAS signal (DGPS fix) of the new satellites, Zenstar III GPS receivers need to update the old version of GSW firmware to GSW 3.2.5. The new version of firmware will help the Zenstar III GPS receiver get a much quicker “DGPS fix”. Please note that the “DGPS fix” also depends on your location. If the WAAS signal is too weak in your location, you may not get “DGPS fix” or need a longer time to get GPS fix. Today, the WAAS signal is not as important as before. There are more and more satellites in the sky and GPS has a much stronger ability to receive signals. Zenstar III GPS has 20 channels to receive satellite signals. It will pick up the strongest ones to get a fix. Therefore, it will get a position fix with very good accuracy whether you use WAAS satellites or not. If you want to update your Zenstar III GPS receiver’s firmware to GSW 3.2.5, please contact us at support@zenstargps.com. We will help you update it. |
