Cellular Interconnect Equipment
Technical Support
ANALOG CELL SERVICE IN THE U.S. HAS OFFICIALLY BEEN TURNED OFF!
Some rural carriers still have limited analog service, but they can turn off analog service at any time without notice. If you were using an analog cell phone to connect to an irrigation controller, auto dialing alarm or notification system (all DTMF controlled), or any other voice controlled device you must now convert to a digital cell phone to continue access to your remote equipment! The Dock-N-Talk™ has been used successfully for years with all irrigation controllers, alarm systems, and other after-market equipment. The Dock-N-Talk™ is the ONLY fully RF shielded device that will allow a digital cell phone to connect to your equipment!
Click on the links below for detailed technical information as well as various methods for connecting cellular interconnect equipment (ie: Dock-N-Talk™, XLink, discontinued Cellsocket, etc.) depending on your own location's phone wiring and your needs. You may print out these instructions and diagrams for your future reference. Please READ YOUR INSTRUCTION SHEET FIRST and this web site before contacting me as most questions can be handled in one of these two places. Doug Foote - D & J Enterprises
NOTE: The FCC will not allow the activation of non-E911 compliant phones by any carrier.
If you are planning to use cellular interconnect equipment with non-cellular commercial equipment (ie: irrigation pivots, pumps, meters, alarm systems, PBX, etc.) please be aware that CDMA carriers (ie: Verizon, Sprint, Altell, Cellular One) do not pass DTMF tones (touch-tones) clearly through their networks. For this reason, it is recommended that you use a GSM or iDEN (Nextel) cell phone in order to interface with commercial equipment.
Lindsay Manufacturing Co., the manufacturer of Zimmatic center pivot and lateral move irrigation systems, upgraded their computer speech boards 2 years ago to clear up the distorted DTMF tones sent through a CDMA network. You can use a CDMA carrier with the latest Zimmatic computer speech board from Lindsay. If your speech board is over 2 years old, you must upgrade to this new speech board to use a CDMA carrier. Contact your local Zimmatic dealer for more information and pricing.
FYI: The Motorola M800 CDMA digital bag phone will NOT interface with cellular interconnect equipment or after-market devices. However, it does have a USB port enabling the phone to be connected to a lap top computer and a Mini-UHF(F) external antenna connection. It CANNOT be used with irrigation pivot controllers nor does it have 3 watts of power.
