Hi There,
Please can someone help? The REM ON (Remote On) RCA plug on the back of the FLEX-6300. I need some very simple to follow instruction on how I can use the REM ON RCA as I am a complete newbi to Flex and HAM Radio. How does the connection work? I have either the WEMo or the Global Cache iTach - TCP-IP to Contact Closure/Relay, So how do I get from a RCA cable plugged into the Flex to the RCA cable being connected to either of the afore mentioned?

It's just a closure. With the Wemo, you'll want to build a power supply and relay box (diagram is here on theCommunity - search). For the Global Cache, there are wire connections that provide a closure. Either way, make sure the function is set ON in your radio settings.

Hi George, perhaps you can help.
Do you know if anybody is using Android device to control the Global Cache IP2CC, if so what App is being used . I am looking for a simple app to operate the relays and report their state back to the Android device, ie 3 buttons that change from red to green to indicate the state of the relays.
Cheers

Eventually, if you want to remote everything from your computer in another room, or, eventually, over the Internet, you will need an Internet remote relay unit. It is addressable over the Internet and you remotely toggle this relay(s) on/off. Connect one of the relays to the remote input of the Flex and, when the relay is closed, the radio is turned on, opening the relay, the unit will turn off.

I was hoping that Flex could remote the power with software but, apparently since this hasn't been done; the above will be a requirement for full remote capabilities.

Thank you for all the reply I think I will be using theGlobal Cache option as it sounds more straight forward. So I just plug in the RCA and then close using the Global Cache, correct?

I am not familiar with Golden Cache. However if it runs on a PC that means you will need a PC next to the Flex. That sort of defeats the purpose of having a stand-alone remote. However, if it gives you a closure across the Remote input it would work.

The Global Cache Lives on your network. No PC required. You will need to open and forward ports and provide some sort of interface software (I use an iOS app called "Roomie."

The relay units are expensive. The A/C power control is much cheaper. Might be more economical to use a remote power unit and engergize a 120 VAC relay.

I agree, Jim, for a single control, the Wemo is not as sexy, but works well. I also toggle the power to my remote antenna tuner, etc. That makes the Global Cache (or equivalent) the option here. I started out with the WeMo - it is quite effective.

Hi, how does it work over LAN, I dont see a ethernet port on it?

It works wirelessly which implies you need a wireless router.

Thanks Jim for the clarification, I wanted to make sure there wasnt an ethernet port on it that couldnt be seen in the picture.

I bought one after hearing about it with the wonderful group we have. What amazes me more, is once you set it up on the LAN you can remote it over a WAN either with WiFi or over the 3G/LTE cell phone network. Wonderful little device for the money!

Yeah they are really neat, I am setting up a new flex 6300 in a remote location.  I am trying to use a spare raspberry pi with a relay module to control the power to the radio but if that doesnt work well I am going to buy one of these wemo's instead.  

The only reason I am not using the wemo to start is I already have a spare raspberry pi so using the pi will only cost me an additional $10 for the relay board.

Maybe you can clarify for me how the remote port works on the radio.  I have been told it works 2 different ways and am trying to find out which one is correct

A) it works the exact same as the power button.  If you short the remote rca for 1 second it will turn on the radio.  if you short it for 3-5 seconds it will do a hard reboot on the radio.

B) the radio will turn on when the RCA is shorted and the radio will turn off when the short is removed.

If the way it works is B, then I am guessing you cant do a hard reboot of the radio using the remote RCA?

B is correct. It does nothing more than turn the radio on and off.

Thanks Jim, so I guess if the radio locks up there is no way to do a hard reboot remote?

Also, I have my Flex connected toa remote A/C power unit. I have never tried it, but if the radio locks up, removing the power and re-energizing should reset the radio to behave.

It's an open collector closure with a built in pull up resistor. So grounding the RCA a will turn the radio on and opening the connection will shut dow the radio.

Yes you can use this to reboot your radio. I have never had my radio lock up to the point where this will not reboot it.

ok great to see so much feedback, I took delivery of the Global Cache IP2CC iTach TCP/IP to Contact Closure (Relay) today, I am fine with the network setup side of things but still unclear how this connects to the 6300.

Am I correct in saying I connect a standard RCA plug into the back of the 6300 and then connect the two wires from the RCA plug into the back of the Global Cache IP2CC iTach TCP/IP to Contact Closure (Relay)?  If this is correct does it matter which wire goes into which connector on the Global Cache IP2CC iTach TCP/IP to Contact Closure (Relay).

You are correct. To ease your concern, buy a  RCA audoio cable cable, strip one end so the shield and center conductor are exposed. Plug the phone plug into the remote input. Touch the two exposed ends together and you will see the radio turns on. Remove the short, and you will see the radio turns off. What you did is what the relay will do remotely.

Ok heads up, and on to the next chapter. I have the Global Cache IP2CC iTach TCP/IP to Contact Closure (Relay) all setup and working on the internal network. I am using as suggested the roomie remote to control the Global Cache IP2CC iTach TCP/IP to Contact Closure (Relay).

Now how do I get all this to work from the internet i.e. get the roomie to talk to the Global Cache IP2CC iTach TCP/IP to Contact Closure (Relay) over the internet. can this be done using NAT and PAT on the broadband router/firewall, if so what ports are used and can I point the roomie to a DNS record/URL?

Not finding much out there on the internet ref the above setup. If possible I do not want to use a VPN back to the home network.

Thanks in advance

Roy

I believe the port to forward is 4498.

Is it possible to control this device over the Internet rather than just over the LAN?

Yes. That's what I do. Port forwarding allows remote access from anywhere. It helps to set the unit up with a fixed IP address in your home LAN first (use the MAC address to set an IP assignment in your router's DHCP assignments). Then you can use your external IP address (from your ISP) and port setting to configure Roomie or another compatible application. 

BTW, the Mac toggle is via a Wemo here. Both devices on the same menu!

I control my 3 WEMO's via my WEMO iPhone and iPad Apps over the Internet
Very Reliable and easy to setup and use.

Being able to remotely reboot radios and computers saved my butt numerous times when traveling internationally..

Tried the WEMO maker device? I had used a arduino board, but required a pc... WEMOs rock, because of you I have 4 now

How do you use the WeMo over the Internet other than just over the LAN? No one will seem to ever answer this question. Thank you.

I asked Tim about powering an LED indicator via the remote function.  Since it is a logic circuit he felt it was not the way to go so I am using the alternate method by tapping into the 5Vdc pins on the Accessory connector to power an LED.  I have an LED on the corner of my dinette seat in my motorhome so I can see when the Flex under the seat is on or off.

Hi, I am putting a webswitch 7 ( http://www.amazon.com/gp/product/B007SP64SM/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 ) in front of my flex 6300 at my remote station.  It's a network power controller, it lets me turn outlets on and off.

Originally my plan was to control power to the radio with the web switch 7 and then use a raspberry pi / relay module to turn the rca remote power on and off.

Then Chris, k6ozy suggested a much simpler method, to connect the RCA remote plug to a permenantly shorted RCA connector.  The idea being whenever the radio is receiving power it will be on; so that the web switch 7 then becomes the sole device to turning the radio on and off (by removing and supplying power to my power supply)

 I would like to ask if there is any possible issues doing it this way?  One thing that came to mind was perhaps having this always shorted would cause it to try to turn on before its ready after receiving power but I dont know if that is an actual concern (and why I am asking :)

Thanks.

If we have an RJ45 port already on the radio... why couldn't we have WakeOn LAN? Would it be possible to implement in future firmwares?
