Green Light Labs GPS-710 Plug-and-Play 'piggyback' GPS for the Kenwood D710-series Radios
Includes - GPS-710 device (20 channel SiRF-III GPS with WAAS ENGOS MSAS augmentation) - 3" serial and data cable jumper kit (longer lengths available) - Built in EMI filters eliminates the need for ferrites near the operation panel - Powered directly from the D710 to eliminate cable clutter - Mounting kit (high bond mounting tape and cleaning pad) - Installation and D710 configuration instructions - FCC Class B tested and certified as D710 peripheral device!
** Designer/Manufacturer's note for TM-D700 Users: "This can also be made to work with the TM-D700(they're electrically compatible), but it loses much of the "built in" advantage compared to when it's used with a D710. On the D710, the GPS sends the serial data to the Operation Panel (which is why it's physically attached to the panel)... but on the D700 the serial data needs to be sent to the RF Base. Essentially, the GPS-710 would need to be connected to the D700 base... which doesn't work well in the common installation pattern of putting the RF base under the seat (or otherwise buried).
"The D700 also has a different cable configuration, so using a GPS-710 on a D700 would require an adapter just to get power. If interested, this is the information on how to make a "pigtail" power adapter out of a common Ethernet cable:
"The GPS-710 accepts an external power input (5-16VDC, absolutely no higher than 16). Using the 3" RJ45 jumper that comes with the GPS-710 as a guide, the wire sequence should go blue-brown-white-black-red-(uninsulated silver)-green-yellow. The uninsulated wire is the shield/ground, and green is +VDC. If you have an old Ethernet wire sitting around, you could snip one end off and scope out the wires that map to the associated GPS-710 inputs... which would allow you to power the GPS-710 from a standard battery. Care should be taken not to reverse the polarity... the GPS-710's internal regulator will be destroyed if ground and VDC are backwards."
