  • SM4 Acoustic

More Info

The GPS antenna plugs into the port on the right side of the EM3/EM3+ and attaches to the back of the device with the supplied fastening "dots". The antenna can be extended if necessary for better placement (during car transects for example) using a standard CAT-5 network extension (male to female) cable.

When the GPS is plugged in, a "?" will appear to the right of the time on the bottom line of the display. This indicates that a GPS antenna is connected and recognized but not yet synchronized. When the GPS has acquired satellites and is time synchronized, the "?" will be replaced with a "$". If the display shows a "!”, an error has occurred communicating with the antenna. Check the connection and try again. The latitude and longitude will be displayed to the right of the time in decimal degrees format.

If the GPS has been used recently in the area, the position fix will take under a minute. If a significant amount of time has elapsed or the GPS has been shipped some distance, the GPS must download new tables. In this case the first position fix can take up to 40 minutes, but subsequent fixes should still occur in under a minute.
