Re: Regulator - 12vdc to 5vdc for Raspberry Pi

 

I hate to be Captain Obvious, but Powerwerx has a product pre built with the correct connectors for both input and output for RaspberryPi and other items that take 5 volts.

Not too hard to make your own cable, be these guys can likely do it for you:??

BTW, I have no connection to these guys and have never purchased any cables from them.

Re: TKR-850 interfacing with a CM108 USB FOB Allstar/Echolink

 

In most cases you only use five pins ( maybe 6 )? in the 9 pin

I use the? Masters Communications RA 42 in one of my projects, but he makes a number of them, from RA 25 ( the simplest ) to the RA 42.

I would change "properly" to "reliably". I run KPG-29D inside DOSBox on my Win 8.1 system & it works flawlessly. OTOH KPG-29D on my old WinXP laptop will not talk to the radio correctly unless I boot DOS on it. Since it's easier & doesn't require dedicated hardware you could just try DOSBox & see if it works. If it does it'll save you some time; if it won't talk to the radio don't waste time fighting it, just boot DOS.

BTW both computers have dedicated serial ports, not USB to serial converters. For desktops w/o a built-in serial port you can get a cheap PCI or PCIe serial card.

Re: Kenwood TK-760H VHF

 

The original KPG-4 used a DB-25 connector for the computer side. The back-shell contains the radio interface circuitry. Later Kenwood supplied cables did change to use the DB-9 connector for the computer connection. The change was made possible by the increasing use of leadless components.

You need to be in a true DOS environment for these older programs to run properly. Best to use an older computer that runs Win98 or XP and boot into DOS. I keep several older laptops around for just such occasions.

Re: TKR-850 interfacing with a CM108 USB FOB Allstar/Echolink

 

I use RA and TA for the audio in/out.? Only one ground is required - the transmit ground.? I use TOR programmed to come out on Pin 25 for the COR signal.? This is the CTCSS and COS combined.? Pin 25 can be programmed to be active negative or positive.? Pin 25 can not sink very much current to ground, and on one install of a link radio (Motorola) I had to put an inverter in the TOR output and program the TOR to go positive instead of negative to get the signal to key the radio.? I used a 2N7000 with pin 25 connected directly to the gate and the source to ground.? The drain goes to ground when TOR is active.

Re: Regulator - 12vdc to 5vdc for Raspberry Pi

 
Edited

I purchased ASIN?B06Y58WLX9, but the one you linked says it is a variation of the one I had already bought so I think it would be the same or close enough.

Squeeze the top cap with some vice grips and it pops off (careful to grip and squeeze as high as you can on the body). There are two screws on either side of the round PCB inside, then the guts pull out. Solder points should be obvious.

Re: Kenwood TK-760H VHF

 

¿ªÔÆÌåÓý

The Kenwood factory KPG-4 cable that I have used for the past 25+ years terminates in a DB-25 serial connection.? If you have a factory cable you will need buy or build a DB-9 to DB-25 cable.?

As far as the aftermarket cables I have seen some that work 100%, some that didn¡¯t work at all, so buyer beware.

Re: TKR-850 interfacing with a CM108 USB FOB Allstar/Echolink

 

Skyler,

Did you tie both the RX & TX GND together off the DB25? I didn't see a schematic for the 850 to see if there was any concern about bonding the two ground pins together...
Only reason it raised some red flags was the service manual alludes to only using the ground associated with the corresponding signal pin. In other words, TX audio use only TX Gnd and RX/RA audio use RA Gnd. Just seems weird that they don't have a common ground pin for all I/O on the 25pin connector.

Hi Mike,?
The 25 pin is "probably" serial.
The connector you referred to as "serial", I assume is a 9 pin. I this case, both are "probably" serial.
These two connector types are quite commonly used in all types of electronic connections. Know what you are dealing with. Many have been surprised with damaged equipment in the computer and communications industry by grabbing a cable and plugging it in "because it fit". Same with microphone connectors blowing mic preamps.
Knowing the wiring (signal and pin#) on the 25 pin and 9 pin, you can quickly make an adapter if necessary.
Been there, seen it, and yes, I've done it!

All the KPG-4s I've seen have a 9 pin serial connector. They may be aftermarket but they should work. Mine works on the TK-805D, TK-860 & TK-880.
