if you use 2 different gps lgc3000s or lgc2000s they will not be networked hence two nmea power connections and switches I COULD BE WRONG sounds possible at some point if system will allow., but with only 1 nm ea power ing the network, but ive never trird this cant afford all them parts to experiment with but may work design seems possible and have slightly different gps readings at each unit,, now if you want to network these 2 you will only use one lgc3000/2000 either or[ thats how mine are, and no problems] i dont see the need or capibilty of two antenns on 1 network never heard of a gps modgule switch box as with trtansducers,[ maybe they could be inependent of one another but still use one power supply and network through t connectors] after all the furthtrest apart the antennas could be is 19-20 ft. max . as far as the grease it needs to be on all connections , t connector. terminators , extension cables, head unit everything and dont be afraid to use it. now ive seen modgules expire before there time usually from leaving them on while head unit is not connected, i always carry a spare lgc2000 and lgc3000 as back ups when travel , grease and a #2 robertson screwdriver for a sure fix. but if it has onyl happened after rain recently its usuall the results from water in connectionc. a quick fix and test ,other than volt test at end of simple network, checks to see if modgule is getting power, is to take antenna connections , head unit connection ts terminators ect. apart let sit in sun to throughly dry, re grease an then assemble.. 1 more thing that could be causing these problems that many are having is a bad switch , poor nmea power,more likly ground nmea power connections with those tiny wires. u can use those super tiny butt connectors will work if crimped propally, and fracture those tiny wires due to vibration over time, but a tiny amount of soider is more dependable and approiate. hope this helps sorry so longLast edited by smbass on April 22nd, 2009, 5:06 am, edited 1 time in total.
