RS-232 over WiFi
Locked

I am considering to place the KAT-500 outdoor near the antenna like Knut AB2TC has done (and reported to this group).
Having looked on the internet for RS-232 to WiFi adapters I can find them in the price range from as low as 40 USD to as much as 350 USD. I wasn't aware of the variety! I wonder if someone in this group has any experience (good or bad) with RS-232 to WiFi units from: USConverters Nordfield USBGear ATC Lantronix Moxa Digi USR IOT 73 de OZ4UN Poul-Erik ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

I used B&B's ES1N. Be careful with most of the Serial-WiFi adapters. Their packet size may be VERY small, so there is a lot of overhead and there may be stuttering using Terminal Mode with the utility. The data goes through, no problem, but the packet transfer timing is up to the adapter.
Lantronix products are fine too. I know a couple of the US leads, and they used some type of adaptive algorithm to differentiate between bursty and streaming data on the fly. 73, Matt Zilmer, W6NIA -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Poul Erik Karlshøj (PKA) Sent: Monday, June 24, 2013 7:40 AM To: [hidden email] Subject: [Elecraft] RS-232 over WiFi I am considering to place the KAT-500 outdoor near the antenna like Knut AB2TC has done (and reported to this group).

I don't have specific experience with Lantronix wireless units, but before retiring I was using tons of Lantronix terminal servers in mission critical zero down time applications. They never let me down. Top notch stuff. Probably not the cheapest but the units I used were highly reliable.
I have no financial interests in Lantronix. David K0LUM On Jun 24, 2013, at 9:53 AM, <[hidden email]> wrote: > I used B&B's ES1N. Be careful with most of the Serial-WiFi adapters.

I have set up KAT500 near the antenna and have about 40 meters run of CAT5
ethernet cable from the shack. Pleased to report that it works well even in presence of 1KW RF going through the tuner into the antenna. 13.8 V DC power supplied to KAT500 through the same cable. 73, Igor UA9CDC ----- Original Message ----- From: "Poul Erik Karlshøj (PKA)" <[hidden email]> To: <[hidden email]> Sent: Monday, June 24, 2013 8:40 PM Subject: [Elecraft] RS-232 over WiFi >I am considering to place the KAT-500 outdoor near the antenna like Knut >AB2TC has done (and reported to this group). > Having looked on the internet for RS-232 to WiFi adapters I can find them > in the price range from as low as 40 USD to as much as 350 USD. > I wasn't aware of the variety! > I wonder if someone in this group has any experience (good or bad) with > RS-232 to WiFi units from: > USConverters > Nordfield > USBGear > ATC > Lantronix > Moxa > Digi > USR IOT > > 73 de OZ4UN > Poul-Erik > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:[hidden email] > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Hi,
Hi. I haven't reported here for a while so an update may be in order. My KAT500 installation using a Lantronics wifi adapter (I think they have only one model) is still going strong, now enduring 90F heat. Fortunately the "cage" is in almost total shade. In the winter I had no problems down to below -20F. I wasn't aware that there were so may choices available for the wi-fi adapter. The Lantronics is rather pricy so if any of these other sources have a good return policy, it might be worth a try. The Lantronics is very well made I have no doubt that it is reliable as many have reported. But it isn't perfect. It's another example of an excellent piece of hardware whose performance is marred by poorly written firmware and/or PC drivers. E.g. the baud rate and likely other serial settings will not change from the default which was set up using their web interface. A B&B Ethernet adapter I was using previously did not have this flaw but I changed it out in favor of the wi-fi because of problems with Ethernet birdies. AB2TC - Knut

Hi Daniel
That's an interesting solution too and cheaper than the WiFi units.

In my case BT does not work reliably byond 10-15 meters. Still useful for
wireless CAT, PTT and CW connection to the radio if it works well. 73, Igor UA9CDC ----- Original Message ----- From: "Poul Erik Karlshøj (PKA)" <[hidden email]> To: "VE3GNO Daniel" <[hidden email]>; <[hidden email]> Sent: Tuesday, June 25, 2013 8:04 PM Subject: Re: [Elecraft] RS-232 over WiFi Hi Daniel That's an interesting solution too and cheaper than the WiFi units.

well, this is a good question, if you are planning to use a "pair" of this devices one as master and one as a slave with some external omni atennas that you might get maybe 80m or so but only in LINE OF SHIGHT!!!, in normal shack conditions with wires and shields I would say maybe 10m or so. Also important the level of interference in ISM band, the modulation for BT devices is GFSK, DQPSK and DPSK, the good part is the BT protocol is designed to avoid 802.11 b/g/n/ac and can go up to 2485Mhz and at least for NA the upper freq is ch 11- 2462 as central freq so at 30dBc you'll get 2473, so there is some free sectrum room to avoid house interference from wifi equipement (in EU I think can go up to ch 14). The BT BW is 3Mhz as far as I remember plus the protocol is close to FHSS one. However the biggest BT killer are the 2.4Ghz wireless phones, try to avoid this at home (I witched with DECT ones). Having a free of interference spectrum will
"extend" the coverage coz the RSSI on wifi devices is not an absolute value (is a long story with wifi/BT rx calibration) and is enterily based on SNR, if there is an interference the BT device will "report" a lower RSSI and will decrease the modulation scheme. In my HF shack I had no problems with HF interference (no wonder the spectrum is faar away) consider mounting this gizmos with external antenna in a pair config and do not relay on internal computer BT card....my two cents vy 73 de VE3GNO Daniel From: Poul Erik Karlshøj (PKA) <[hidden email]> To: VE3GNO Daniel <[hidden email]>; "[hidden email]" <[hidden email]> Sent: Tuesday, June 25, 2013 10:04:59 AM Subject: SV: [Elecraft] RS-232 over WiFi Hi Daniel That's an interesting solution too and cheaper than the WiFi units.

I am concerned about the reliability of BT for RS-232. My new 2014 Jeep has BT in the entertainment center and it drops data during songs from my iPhone and Pandora apps with the iPhone about 2 feet from the entertainment console. I'm thinking that these holes in the music audio may be due to a faulty BT module in the Jeep's audio system.
I've never really used BT before now. Do most of you find the BT connection reliable enough (sans obvious interference) to pass RS-232 accurately from my PC to the K3? 73, Terry, W0FM St. Louis, MO ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Appologize for SNR with this side wireless protocols, very much away from our primary subject, the problems withn BT devices and IPhones is quite well known and is not caused by interference but by bugs in protocol implementation on both ends, (IPh and 2014 Jeep BT device). If you'll sniff the air with a BT sniffer you can easy see what is the rootcause. Speaking abt Apple and wifi/bt bugs, in the last 2-3 years a huge number of cross-compatibility problems occured in the market, some fixed some never addressed, the latest one (few days ago) is with wifi on new macbook air, try to keep updated both devices with latest fw or use another handset (I assume you'll not willing to change your car, is cheaper to change the handset loool). This is consumer market, is waay different as business model than Elecraft business model, in a year or so any consumer device will be obsolate anyway so nobody cares too much abt bugfixing.
