[Today’s run: rest day]
No run yesterday or today.
Yesterday we got up before the chickens and drove the old F-150 down to Jackson, MS with stuff to sell at the hamfest.
We had a good day and got rid of a lot of stuff. There are always a few wheeler-dealer guys who buy my stuff and then display it for sale on their own table. I got my $$, so I’m not distressed about it, but I find it kind of humorous. I guess that is how commerce works!
Anyway, I got rid of: TS-830, National NCX-5, dsPIC development board, 8051 development boards, Polarad satellite band signal generators (2), 3-com network switches (2), box of 1940’s era radio magazines, HP analog RMS volt meter (which I had paid too much for at an online auction), some parts of mobile radios.
And I bought a few things. I bought some UHF connectors and a few crimp-BNCs which may be a wrong size ferrule (we’ll find out), and two analog video cameras.
Since arriving back home I have been able to determine some info about the video cameras.
Then are labled, “Kustom Signals, Inc” and EVI-400. They are a repackaged Sony EVI-400 camera. They have zoom and autofocus. The connector is an 8-pin jobbie. I was able to cut down a computer ribbon cable to 2×4 and that fit fine.
Signals / pins :
- V++ (goes into an 8 volt three-terminal regulator)
- Serial TxD (connector CN204 pin 1)
- Ground
- Serial RxD (connector CN204 pin 4)
- foward facing LED (ground pin to light LED)
- Serial DTR (connector CN204 pin 2)
- Serial DSR (conector CN204 pin 3)
- composite video output
The guy sold me two of these cameras for $15 and both appear to work. I have not tried to talk to their serial communications lines yet. They use a protocol called VISCA and I have some work to do in that area. I will have to figure that out if I want to use the zoom feature.
Kustom Signals Inc has a website and appears to focus on police and public safety market. I’m thinking these were probably in-police-car video. Who knows, maybe the video from one of these cameras appeared on “COPS” or something.
