Salut am si eu o intrebare daca am inchidere centralizata fara telecomanda , ii pot cumpara doar telecomanda si sa o motez sau trebe schimbata toate inchiderea....si daca se poate cam cat ar costa unsure.gif

Masina are sau nu CAN ? Cel mai probabil, nu. Atunci ii poti monta telecomanda pt inchidere linistit.

Daca e Honda aceea din 1996, sigur nu are wink.gif

CAN-BUS: http://www.pcmag.com/encyclopedia_term/0,2...;i=39243,00.asp

"CAN-BUS (Controller Area Network bus) is a rugged, digital serial bus designed for industrial environments. Introduced by Bosch in the mid-1980s for in-vehicle communications, it is used in myriad applications including factory automation, building automation, aircraft and aerospace as well as in cars, trucks and buses. CAN bus replaced bulky wiring harnesses with a two-wire differential cable (the two wires carry inverted voltages to decrease interference).

CAN provides services at layers 1 and 2 of the OSI model and uses a broadcast method for placing frames on the wire somewhat similar to Ethernet. Bus distance is based on speed, ranging from a maximum of 40 meters at 1 Mbps to a maximum of six kilometers at 10 Kbps. At speeds up to 125 Kbps, CAN provides fault tolerance. If one of the two wires is cut or shorted, the other keeps transmitting.

In a vehicle, both low- and high-speed CAN buses are used. For example, window, lighting and seat control only need low speeds, while engine, cruise control and antilock brakes require high speeds. Two or three CAN buses may be used in a vehicle; for example, a high-speed bus may be dedicated only for safety (air bags, seat belt tensioners, etc.).

The Bus Hampers After-Market Installations
The CAN bus has made it challenging to add certain after-market products to a vehicle. In older cars, there were discrete wires for everything, but CAN bus signals are digital frames that have to be analyzed to determine their purpose. For example, taxi meters and many GPS navigation systems need to monitor vehicle speed. If speed pulse is no longer available as a discrete wire, a CAN bus interface, such as the CANM8-NAV unit from Bridgewater Electronics (www.bridgewater-electronics.co.uk), can convert speed pulse frames to a speed pulse signal.

CANopen and CiA
Introduced in 1995, CANopen is a high-level application layer protocol that provides services for processes, data and network management. The international organization that governs the CANopen protocol is CAN in Automation (CiA). For more information, visit www.can-cia.de."

Cu alte cuvinte, e o idee buna pe care au furat-o si astia din domeniul auto si o aplica uneori cu picioarele. Folosesc multiplexajul ca sa simplifice cablaraia. Iar asta iti ofera posibilitatea sa blochezi un sistem vital (sa zicem, regulatorul de viteza) daca ti se blocheaza unul auxiliar (sa zicem, stergatorul de parbriz). Pe pe seama lui se pun istoriile cu masini blocate pe regulator, masini care refuza uneori sa franeze, etc.

Tot pe seama lui pun si eu faptul ca uneori, sa zicem in 5% din cazuri, cand ploua afara, merg stergatoarele mi se "reseteaza" bordul. Evident, mecanicii pun asta pe seama stressului si a etnobotanicelor.... ca genul asta de gherle nu lasa coduri de eroare sau alte urme.

Gasesc la piese auto o telecomanda cu un senzor ceva?Ca banuiesc ca trebe si un senzor.. smile.gif

Cel mai simplu e sa-ti pui o alarma cat mai ieftina, cu telecomanda care sa controleze inchiderea
Nu pentru alarma in sine, ci pentru telecomanda smile.gif Alarma e bonus, numai vezi sa nu fie de-aia care trezeste vecinii noaptea; mai bine o reglezi pe sensibilitate minima.
