Literally 'measurement at a distance', telemetry is used for monitoring environmental conditions or system and equipment status at remote locations. Examples of environmental monitoring include weather, river flow rates and water levels, seismic activity, pollution levels, and traffic/road condition monitoring. Typical system monitoring and equipment status applications include pipelines, electric power transmission lines, water and wastewater treatment plants. Any time you need to measure something located in an inconvenient, inhospitable, or moving location, on a continuous or periodic basis, you have a good application for telemetry.Kantronics offers a several products addressing the needs of telemetry applications. Our Talon UDC Data Radios combine a radio modem and transmitter in a self-contained, compact package. All you have to add are power and an antenna.

These data radios are available with built-in analog and digital inputs and outputs, further minimizing external cabling and equipment. These data radios are available for VHF or UHF Land Mobile Radio bands. For telemetry applications requiring location, velocity, or extremely accurate time information along with the sensor data, these data radios are available with a built-in GPS module. For applications where the data to be monitored is already in serial form, the Talon offers a serial port. Kantronics provides a user-configurable sample telemetry application free for use with our Talon data radios. You can download a copy (ZIP, 353k) to get a glimpse of what is possible. The program requires Microsoft.Net framework to run.
See the readme.txt file in the.zip file. While you obviously won't see live data unless you have a Talon data radio, you can configure the sites and displays without the radios.If you need to operate in other radio bands, or dual-band configurations as part of a network, or simply wish to re-utilize existing radio equipment, consider our commercial radio modem/TNC products. These include the KWM-1200+ single-port, low-speed modem, and the KWM-9612+ dual port, high speed modem.
Both modems include built-in A/D and serial inputs.All of these products are designed to meet the needs of telemetry applications. They offer high reliability, operate well even in rugged environments, and require low power. They are just as well suited to remote or mobile application as to urban, fixed location use.
Land lines These incur monthly costs(frequently increasing with physical distance), and are not an option in remote or mobile locations. They are also more susceptible to outages requiring repair, due to their physical link (vulnerable to induced surges and cable cuts). Cell-phone based systemsWhile cellular companies are increasingly offering data options, they come with high recurring monthly costs, limited coverage areas, and spottier reliability. Data needs are being addressed as an afterthought, with corresponding problems such as difficult and non-standard cabling to user data acquisition equipment, little provision for external antennas to address poor site-line to the cell network, and lack of control over device power. (Some equipment specifically sold as cellular modems has no way to turn the unit on or off except via the handset, making power management difficult!) In addtion, most cellular equipment is not designed for harsh environmental conditions. Satellite-based systemsWhile satellite-based systems can offer excellent coverage area, it comes at high initial and ongoing costs.
It also comes with high power consumption and equipment environment constraints. Satellite communications is also subject to rain fade (loss of signal during rain between the ground station and satellite), and signal delay due to the increased distance the signal must travel. SCADA systems add Supervisory Control to the Data Acquisition function of telemetry systems. Supervisory control can analyze the data acquired from remote equipment throughout a system, and command corresponding adjustments across the system to maintain safe, efficient operation. In utility applications, these adjustments can redistribute power, or pipeline flow, to best serve current demand, and to bypass equipment failures and safeguard equipment and operations.While mobile equipment location and dispatch could fit within the definition of SCADA systems, the specialized needs of the application are addressed on our Vehicle Tracking applications page.
SCADA system users demand highly reliable communications equipment, and Kantronics delivers. Reliability starts at the factory with thorough product testing before the equipment goes out the door, resulting in a low 0.003% warranty return rate.
Our quality firmware follows up with error detection to ensure that data reception errors don't make it through to your system. A choice of protocols allows you to select the operating modes most appropriate to your application. All along the way, our friendly and experienced staff stand ready to assist you in selecting the most appropriate solutions for your communication needs, including the following Kantronics models:Talon UDC Data Radios combine a radio modem and transmitter in a self-contained, compact package. All you have to add are power and an antenna. These data radios are available with built-in analog and digital inputs and outputs in addition to the standard I/O, further minimizing external cabling and equipment. These data radios are available in VHF or UHF Land Mobile Radio bands. If your system includes mobile components, Talon radios are available with a built-in GPS module.

Sometimes called AVL (Automatic Vehicle Location), vehicle tracking provides useful information to fleet owners, construction, transportation, service and sales companies, about the location of the vehicles, mobile equipment and employees. These systems fall into two categories, with overlapping application:Active tracking conveys the location information immediately via a radio link, and allows for two-way communication to reallocate vehicles (buses, for example) in the field to meet current needs.
Compared to voice dispatch systems, automatic digital transmission of vehicle location allows the driver to focus on driving, and can continue to report position even if the driver is away from the vehicle or incapacitated, a definite aid in emergency situations.Passive tracking simply records the location/time/speed information for later retrieval, avoiding the cost of radio equipment when immediate action on the information is not required. An example of passive tracking application would be to examine sales and delivery routes over time to help determine more effective, less costly routes. Ideal for active tracking applications, Kantronics Talon UDC Data Radios combine a radio modem, transmitter, and optional GPS module in a self-contained, compact package. All you have to add are power and an antenna. These data radios are available with built-in analog and digital inputs and outputs in addition to the standard I/O, further minimizing external cabling and equipment.

I have the original manual, commands manual, and a few others. The problem is talking to the TNC or even knowing if it works in the first place. I am hooking it to an old Pentium II that is installed with Ubuntu 8.04 Server Edition (command line) and is working great hosting a website and acting as an SSH server so I can work on my laptop with it, that way I do not need to be at the computer, have a monitor, or keyboard attached.I am trying to use minicom to access the TNC but now its giving be an error that the 'device disappeared, aborting' and quits back to the command line. I do not know how to even tell if the computer sees the tnc or not, I have it directing to /dev/ttyS0 which should be COM port 1 which should be my serial port.
Any help would be great! I've used one for a number of years.In addition to the previous poster's comments, a reset is best done by temporarily removing the battery (30 seconds), then reinstall it. Slipping a business card under the battery tab also works.Then, start your terminal emulation program (VT-100 is good) and begin typing as asterisk (.). If the TNC is working, it'll respond with something in English - and then, you can proceed by making your parameter changes.Your initial error (port disappearing) sounds like a computer or OS issue.73.
