It doesn't need a usb driver, it uses rs-232 thru the computer's serial port. If you don't have a true 9 pin serial port, which a lot of computers don't have anymore, and you are using a usb/serial port adpater, you will need a driver for that adapter, but not specific to using the garmin.

The thing you are missing is the duplexer has TWO notches for a reason. Yes the big side is the receiver side notching out the transmitter frequency. BUT you also have a notch for the receive frequency on the transmitter side for a very good reason. The transmitter is going to have some noise on the RX frequency, it’s not enough to be picked up a mile away but it’s enough to dense the receiver with an antenna right next to it. There is a reason this isn’t done.
@dc9581118 күн бұрын
Both notches are used, 1 blocks the transmit freq and the other blocks the receive from going into the dummy load. The duplexer is tuned the same as a normal application. It works perfectly as described if you transmit high (159Mhz) and receive low (151Mhz). I found that if I reversed the tx and rx frequencies I would get a very large desense that would really limit the coverage. Your timing is amazing on the comment because I did find the cause and a solution to that problem. I learned that most all of the times I blamed desense on a receiver having its frontend overloaded, it was more likely a near-field on-frequency rf product that was desensing it. I just made this video showing how it does it.
@BVN-TEXAS18 күн бұрын
That’s not how that works with the dummy lord. You are basically only using one side of the notch. The reason for the transmit side going through the duplexer is so that side notch can be set to notch out any spurious signals coming out of the transmitter that would be on the receiver frequency. The amount of loss you are going to see by running the transmitter thought the duplexer is really not much. Plus by using using the same antenna for both you won’t end up with an alligator or elephant repeater. And I say this from having a mobile repeater in my 4Runner and having a uniform antenna pattern is really the goal and makes you no always wonder about TX or RX issues.

ok i have a scenario where i need to have tcp/ip devices talk and send about 1Mb over an rs485 network. can that be done w these? Basically lose the network switch and connect one rs485 adapter to internet, connect rs485 between both devices and a pc on the other end. will it work?
@dc9581124 күн бұрын
I know exactly what you are talking about. A reverse bridge. I had the same idea for rs-232. The answer is no. I will put it simply, those devices can only communicate on the ethernet with other devices like itself, that does rs485 stuff. It would have nothing to say to any of your other tcp/ip devices and would ignore them.

People were so afraid of the high leg that they pulled the fuses to the high legs at the service disconnects, but that way it can never be balanced, so I’m using the high legs and one other leg for each and every 240volt device, then when everything is finally done and working, I plan to balance things using a clamp on amp meter. I’m not a licensed electrician, but I do what I can before calling in the electricians to check everything and fix any issues prior to inspections, saves my boss a whole lot of money that way.

No head/interface board swap like a Motorola. Make sure the firmware is the same version between head and radio.

@dc958117 ай бұрын
It is impossible to directly convert that without being able to control the sentences put out by the GPS, and the rate at which the GPS outputs the sentences. Too many sentences means too much data without enough time to get it out, and the buffer gets involved and then quickly overfills. So you would have to reprogram the GPS. But here is the good news. The GPS module can be reprogrammed for 4800 baud. If you look on page 36 of the mega spec sheet on the NEO-M8 at the link below, you will see 4800 is a selectable option. I know you have to use UBlox U-Center to reprogram the modules. I haven't done it myself, I'm a Garmin guy.

@dc958118 ай бұрын
There are a lot of things that have to be clarified. 1. First define what you mean by wifi "turns off". That could mean many different things. Is it disconnecting but staying enabled? Is it disabled? Or does it just not work? 2. If you unplug the ethernet cable, does the wifi automatically start working again? If not, what exactly do you have to do to get it working on wifi again? 3. The NCSI, the network connectivity status indicator, will always take ethernet control as far as what is seen in your task tray at the bottom right of your screen, that is because it wasn't meant to show 2 at the same time. But that doesn't mean wifi isn't connected at the same time and is working. I could just go on and on. But I think in answering these questions you would find the answer to what is happening. Think of it from the app's side, it wants this data and it has 2 choices from where to get it from, which does it choose. If it thinks it can only get that data from just 1 side it will always pick that side to get it. Task manager performance screen is the only real way to easily see what it is chosing in real time.

Thank you. No. BK has forbidden entry into the world of adjustments for anyone outside their factory. I see you found the "medium" mobile setting that gives you 50W. As far as licensing, those are rated for effective radiated power ERP measured at the antenna. Unless you have some super quality, or super short coax, you will more than likely drop that extra 16W before hitting your antenna. And then only a portion of that signal will be fully converted to rf energy, with the rest reflected back to be turned to heat on the radio heatsink. Put a wattmeter with a dummy load at the NMO adapter to test.
