Wiring ais cyphose 101

[youen]

Today i make à mistake when wiring my Cypho ais receiver I have connected the wires of thé output nmea to the 12 volts do you think That I Can have damaged the receiver.I Can check the system because the boat is in a shelter and so is enable to receive vhf signals

Sorry I am unable to help you but I'm sure one of the electronics experts on the forum will know the answer.

In the meantime you might take a look at a User Manual if you hav'n't got one already.

I read it but there is nothing about such silly mistake!!!

 

[coopec]

This may be technically stupid for some reason but I wonder if can you get hold of a hadheld vhf and see it recieves/ transmits over (say) 10 meters?

 

[youen]

I need to have a boat in vicinity which transmit an ais signal,my Cypho is only a receiver

 

[youen]

À precision the bad wires were thé nmea red and blue

You'll have noticed that the link which Coopec gave is for the wrong receiver (the 150, when you have the 101). You can download the correct manual from this link...

However, even the correct manual doesn't give an answer to your question. It does say that the Power light will be constant green when the unit is operating correctly - is this the case with yours?

You can't resist the chance to have a go!!!

I (perhaps wrongly) assumed the result would be the same regardless of model

No, I was trying to help the OP by posting correct information. If I wanted to have a go at you I'd have commented on your ridiculous suggestion to use a handheld VHF to test it!

Yes, OK.

About 10 years ago I was using my computer to track vessels and they(?) contacted me to see if I would become an automatic AIS station. They wanted to know my elevation above SL and how close to the ocean I was. The only requirement was that I had to leave my computer on 24/7 which I declined. (From memory the aerial was not a real concern and I think they would have paid the cost of it) Apparently vessels leaving Fremantle were quickly "lost" because there was a dearth of AIS stations up along the coast. I just went to the Marine Traffic website.

I can't believe how its use has grown because few recreational yachts had AIS in those days.

Thé Green light is on but I dont know if the nmea 0183 output is working

I won't argue because my knowledge of AIS is poor but I thought you could use VHF frequencies with a GPS and transponder.

But No?

AIS frequencies in the VHF maritime mobile band

Internationally, AIS uses 2 dedicated frequencies in the VHF maritime mobile band:

• 161.975 MHz (AIS 1)
• 162.025 MHz (AIS 2)

Is the receiver somewhere near to the sea? Is it likely that there may be ships nearby transmitting AIS? You could perhaps check by looking at the MarineTraffic website. The fact that your boat is under cover doesn't necessarily mean that VHF signals won't reach it.

Of course the OP's AIS device may well not conform to any standards but there is good reason to hope that the incorrect wiring will not have done any harm.

The output driver will likely be an integrated circuit conceived for driving RS232(1), and that specification includes:

"The standard specifies a maximum open-circuit voltage of 25 volts: signal levels of ±5 V, ±10 V, ±12 V, and ±15 V are all commonly seen depending on the voltages available to the line driver circuit. Some RS-232 driver chips have inbuilt circuitry to produce the required voltages from a 3 or 5 volt supply. RS-232 drivers and receivers must be able to withstand indefinite short circuit to ground or to any voltage level up to ±25 volts." [Bold highlighting mine, text taken from Wikipedia]

So there's hope all still works!

(1) The NMEA standard now asks for RS422 rather than RS232 signalling, but this is usually observed on consumer grade equipment running at such low baud-rates as 38400 merely by providing an extra ground wire, so RS232 still holds good.
