The Controller Area Network data rate can be from 10kbit/s to 1Mbit/s giving recommended distances of 40 to 1000metres over two twisted pairs, one for the data, the other to carry power and ground. Up to 110nodes may be connected. 2. Set the DIL switch on each board to the required node number 0to127. The actual value is unimportant, providing the

y are different —we suggest 2and3. 3. Connect together two nodes, each consisting of a TDS2020CAN with either a TDS2020F or TDS9092 computer. Use a cable with two twisted pairs, connecting pins 2&7, and 3&9, having a female connector at one end and a male at the other. Leave the other two CAN connectors open. 7. Type CANTEST and return on each computer in turn. An incrementing number is transmitted which all connected and initialised nodes will receive and display. Verify that you see the message when you change the PC plug to the other node. Stop the test with any key (ctrl+C on TDS9092). 8. Type ROLLCALL and return on each computer in turn. A memory transfer is made to all of the 128 possible nodes and responding initialised node numbers are displayed. In this case, just the identity of the other node should show. Controller Area Network is a bus operating at RS485 levels, 0V and +5V in push-pull to give common mode immunity. Instead of being character based, it sends messages of up to eight bytes. Each of these frames has an identifier and any node with a matching identifier will receive the message. Each node can be either a TDS2020F+TDS2020CAN or TDS9092+TDS2020CAN combination. The number of nodes which the network can support depends on cable lengths and bit rate, but the CAN bus driver chips are specified for at least 110 nodes. The nodes are daisy-chained, the male and female CAN connectors being internally...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
