Re: RF D RATS Using ID-880H Mobile

 

开云体育

Mike,

This is an excellent find. ?I will give you credit for that. Since I run Linux, it is good to know that they work on Linux.

I have an IC-706 and an ID-880 in my truck. ?I have been thinking about adding a computer so I would have access to NBEMS and D-RATS in the truck. These cables are just the ticket to do that. ?I also plan to replace the really old USB to serial adapters that I have been using on everything else. ?

I have a Raspberry Pi that I use with my DVAP. ?I would like to be able to set up a ratflector on that as well. ?Perhaps you could provide some insight as to how you set yours up.

Thanks

David, AC7DS

Hi David,

I'm happy you found it useful.?

The cables are not shielded, but I've never had an RFI problem using them. A few ferrite snap-on beads might not be a bad idea as prevention, though.

I've used these cables as D-STAR rig data/programming cables and as rig control cables for the Yeasu FT-450s HF rigs our EOC has in our GO boxes.?

You can also get TTL level output versions, both 5V and 3.3V level. I've used the 5V TTL level version for ICOM CIV rig control of IC-706, IC-7000, IC-756Pro and IC-7100 rigs. For CIV use the 5V TTL output version of the cable instead of the RS-232 level and short the TX/RX wires together, then install the appropriate mating connector.

I'm using a 3.3V TTL output version to talk to the serial port of the Raspberry Pi that's running the N0SO Ratflector.

The cables work well with Linux and Windows, I've not tried them with a Mac.

I'd like to claim this idea as my own, but it's not. I started using these cables at the suggestion of a young man that I talked to at the ICOM D-RATS booth in Dayton a couple of years back. I don't ?remember his name or call to give credit where it's due.

73,

Mike,


Those cables are awesome. ?I need to get 10 or so... ?Have you had any RFI problems connecting them to the radio? ?They don't look like they are shielded.

Thanks

David, AC7DS

If you're handy with a soldering iron, these FTDI USB to RS-232 "wire end" cables work well:

The cable is a USB plug / converter at one end and "bare wires" at the other end. You will need to solder on a connector that fits your rig, in most cases a 2.5mm stereo plug (that's where the soldering iron come in). Connect the Orange wire to the tip, the yellow wire to the middle sleeve and the black wire to the base. You don't need to connect the other wires.

Pick your 2.5mm plug carefully, most of the ICOM rigs require a pretty narrow backshell on the plug. I've been known to leave the plug off and just cover the connections with heat shrink tubing.

The cables are about $23 from Mouser Electronics. They work well, I've made several.

The cable from RT systems that John suggested also works well. It may cost a little more, but no soldering would be required.

Now that I have a working D RATS program using the internet, I am wanting to set up a RF connection. Does anyone know of a USB version of the OPC-1529 data cable? If not, what serial to usb converter would you recommend? ?I am running Windows 8.1. Looking for recommendations from those that know the converter will work.
