OPCOM don't work

[knuffifix]

Hi,
I've bought a OPcom, but it does not work. I used the version OPcom 090420 and the clone version 08.2010. The interface is detected in the test but it does not connect to a control device. Although you can hear the relay click and the green LED (Rx) flashes from time to time.
I have already flashed the EEPROM with OPcomFUT29b, but he still does not work.
I need help!

What pins did you tested ? engine? airbag ? dash ? can ?

I tested engine, airbag and dash. CAN I have not tried because I had no car with can

Scrool down the opcomfut and see final mine look same bun scrooling down I see error flashing faild

Flash worked but the interface does not communicate with the controllers!

I found the solution!
I have soldered the relays and tested, 2 of 8 were broken. I once tested the control with LED's and identified which are activated when, if one selects different PINs in the program. A relay is controlled apparently not at all.

If enyone hawe a shematic for this type of opcom please post it here.My problem with OPcom is :Molten power diode and condensator /C20/after replacing and reflashing the PIC ,software tell -all ok ,but can not connect to any car .Some relay is working and led green and red is ON at powering up the interface.

Are you sure the relay work? I have soldered the relays and check if it clicks when voltage is applied to the coil.

Ok i will see this,but why the green led is still on,without car?

If you connect the interface to the PC, the red power LED and the green Rx LED lights. This is normal. The interface involves the power from the USB port, you can hear the relay click when man wants to make a diagnosis.

I have almost as problem, but for me, work only on CAN.
I want to go to colegue MisuB (http://www.digital-kaos.co.uk/forums/members/63448-mishu_b/) to resolve that, but... I want before somme indicatins. Thanks.

Hi

Throw in open toilet and order another one .

Hopefully it will pay itself within a week.


Btw we have got open toilet elections tomorow....


Pick and choose in the new south africa,,,,,....:manuflag:

just take a look at those nice relays "CHINA" , so don't expect much from them! I had one worked one week , with other type relays , but it started to ~~~~ my brain - no Hi CAN , later no MID CAN , I was crazy . Finally I ordered another on with JAPAN made relays - till now I am happy with it.

Were can we buys those relays? And part no ?

It is cheaper to buy new OPCOM clone than 8 relays

So were can I get the japan relay opcom clone?

[DB77AAA]

From another OPcom Clone?!?

Thanks m8

So these relays are straight swap
