It can also be used as a land-based spotting telescope for daytime and wildlife observations. Your NexStar 130SLT will reveal details of the lunar surface, Venus and its phases, the polar caps on Mars, Jupiter and its four moons, and Saturn with its rings plainly visible. This makes NexStar 130SLT your perfect companion for impromptu observing sessions and all-night stargazing marathons alike. The entire telescope kit is a simple, no-tool assembly and fast SkyAlign alignment procedure will have you ready to observe in minutes. This telescope comes with a pre-assembled, adjustable stainless-steel tripod, quick release fork arm, NexStar+ computerized hand control, 130mm Newtonian Reflector optical tube, and lots of bonus accessories. This radio would be in the hands of the farm workers allowing them to switch the pump on for whatever reason.Celestron’s innovative NexStar Star Location Telescope (SLT) has been a customer favorite for years thanks to its unique combination of high-quality optics, a user-friendly computerized interface, and a sturdy single fork arm mount. Pressing the button has the same effect as closing float switch A or B. Radio 3 (not shown) also has the option to manually start the pump by pressing a pre-programmed button. As soon as the reservoir gets to a certain level, switch B closes and radio 1 sends a telemetry command to radio 2, which turns the pump off. Radio 2 reacts to this command by toggling the pin connected to the motor controller. So as the reservoir empties, float switch A closes and causes radio 1 to send a telemetry command to radio 2. When the input is high, the motor will run and as soon as the input goes low, the motor will stop. The control circuit also provides a low level input for starting and stopping the motor. This circuit provides soft start and power factor correction for the electric motor inside the pump.

In this application, the reservoir is fitted with two float switches: one switch closes when the reservoir is full and the other switch closes when the reservoir is empty.īetween the pump and radio is a simple control circuit. In the case of the portable, a telemetry cable (PMKN4040A) is required which informs the radio that a special cable is connected.Ī popular example of how MOTOTRBO can be used for telemetry is a reservoir control system. In addition, any of the programmable buttons can be set to trigger a telemetry command. Portables have three GPIOs and mobiles have five. It also enables the target radio to display a programmed Text Status Message or act on a telemetry command received from the originating radio responding to an event at the originating radio's GPIO pins. The telemetry commands can also be used to query the status of GPIO pins at the target radio. Telemetry commands instruct GPIO pins on the target radio to be set, cleared, toggled or pulsed. Sending the telemetry command can be triggered either by GPIO pins or a programmable button. With this telemetry functionality, the originating radio can send a telemetry command to another radio.

Both the MOTOTRBO portable and mobile, have General Purpose Input/Output (GPIO) lines on the radio accessory connector which can be connected** to external equipment. Most MOTOTRBO radios* support telemetry functionality in digital mode.
