NISMOPC Posted March 12, 2018 Share Posted March 12, 2018 Not an expert on this, but was planning to purchase the Lantronix UDS-10 to mate up with my 850 and get my 8-bits online. I saw these and was curious if they would achieve the same "modem mode" that the Lantronix provides... https://www.ebay.com/itm/Ebyte-E44-DTU-1W-SX1276-915MHz-LoRa-RS232-RS485-Wireless-radio-modem-transmitter/192161708809 There are several different versions of the same item with same specs, but none reference "modem mode". Thoughts? Quote Link to comment Share on other sites More sharing options...
Omega-TI Posted March 12, 2018 Share Posted March 12, 2018 You can also plug a Vonets "VAR11N" WiFi gadget into a USD-10. I've been running one for years. These things are CHEAP on eBay. They are under $15.00... shipping included from China. The only drawback is a three week wait. Quote Link to comment Share on other sites More sharing options...
NISMOPC Posted March 12, 2018 Author Share Posted March 12, 2018 That's a nice set-up, but was thinking this unit is an all in one converter and wifi. One less thing to buy and they seem to be super cheap as well... Quote Link to comment Share on other sites More sharing options...
+Spaced Cowboy Posted March 12, 2018 Share Posted March 12, 2018 Short answer: no. This is a radio-modem. RS232 serial on one side, radio communications on the other. It's designed to work with a counterpart of itself and not need a wire between them. The idea is you have [pc1]<--->[radio modem 1] < ... ~ ~ ~ ~ ... > [radio modem 2]<--->[pc2] So software on pc1 can talk to pc2 over an RS232 serial connection, even if there aren't any wires between them. What it doesn't give you is a frequency-range that can directly interact with WiFi - this modem is using the 915 MHz band, and WiFi is on 2400 MHz (and other bands higher up the frequency spectrum). Never the twain shall meet. Longer answer: What you *could* possibly do is get two of them, use the 850 on your atari to connect one of them to the atari, and connect another to a linux box. Then you could use ppp on the linux box to link up the linux-side serial device to ethernet. This *ought* to give you a raw connection to the internet on the atari, but then you have to run a TCP software stack on the 8-bit. It might be better to put something in-between (on the linux box) that does most of the heavy-lifting, and then sends just the data-packets down to the 8-bit. Please understand, this is not a route for the faint-hearted, there's a lot of work to be done here. Even longer answer: Wait for me to finish up my expansion box (maybe a year or so ) and plug in an ethernet card.... 2 Quote Link to comment Share on other sites More sharing options...

ricortes Posted March 12, 2018 Share Posted March 12, 2018 Do modern WiFi routers all support 900 MHz? I think they offer backwards compatibility but everything defaults to 2.4 or 5 GHz now. Quote Link to comment Share on other sites More sharing options...
+Spaced Cowboy Posted March 12, 2018 Share Posted March 12, 2018 Do modern WiFi routers all support 900 MHz? I think they offer backwards compatibility but everything defaults to 2.4 or 5 GHz now. TIL So maybe it's theoretically possible after all. I think it's pretty unlikely because the protocol spoken by the radio modem is highly unlikely to be compatible with that of IEEE 802.11ah. I would go so far as to say "vanishingly unlikely", but you never know... Looking at the spec, I can't see any mention of 802.11ah though, and it only claims 65535 addresses (not the 4 billion or so of TCP/ip).

NISMOPC Posted March 12, 2018 Author Share Posted March 12, 2018 The WiFi232 is also a popular item... Yea, been watching for these - Never in stock and last I read, he's no longer making them. Might just go the Lantronix route via router and R45 cable. Just thought it would have been a great alternative all-in-one with that Chinese WiFi unit, but Lantronix is known to work and I have found nothing on those cheap Ebay units.

V-Cool Posted March 16, 2018 Share Posted March 16, 2018 The Wifi232 sold out August 2017. He said at the time that he will "revisit soon". He still has the tweet pinned so hopefully he will start again. Quote Link to comment Share on other sites More sharing options...

Banquo Posted March 16, 2018 Share Posted March 16, 2018 I was going to recommend something like the Lantronix MSS-100 because it supports DNS and you wouldn't have to look up IP addresses to type in, but the UDS-10 is fine too. However from what I understand, and someone correct me if I'm wrong, you need the Atari CX-87 modem cable for the UDS-10, not the CX-88 null modem cable. However you can use a null modem adapter to convert it if I'm not mistaken. Quote Link to comment Share on other sites More sharing options...
Sugarland Posted March 16, 2018 Share Posted March 16, 2018 The Lantronix SCS100 also works. I'm not sure of the differences between the the SCS100 and MSS100. Looking at their website it seems the MSS100 has firmware that is a little newer than for the SCS100. When I got the SCS it seemed to be a newer/updated product over the MSS so I went with that.

+Nezgar Posted March 18, 2018 Share Posted March 18, 2018 Networking being one of my many hats, I had the brainwave to configure the AUX port on a Cisco router as a serial terminal server and it works great! Connected via PR connection, BobTerm at 9600 to a couple telnet BBS's in ATASCII mode tonight. It was a very nostalgic experience haha. Old cisco routers can be had cheaply, but of course have a bit of a higher learning curve if you're not familiar with configuring them... future post idea to document I guess 4 Quote Link to comment Share on other sites More sharing options...
NISMOPC Posted March 18, 2018 Author Share Posted March 18, 2018 (edited) I was going to recommend something like the Lantronix MSS-100 because it supports DNS and you wouldn't have to look up IP addresses to type in, but the UDS-10 is fine too. However from what I understand, and someone correct me if I'm wrong, you need the Atari CX-87 modem cable for the UDS-10, not the CX-88 null modem cable. However you can use a null modem adapter to convert it if I'm not mistaken. So, I read mixed responses in my search results. Seems like CX-87 needs a null modem adapter, but the CX-88 is already twisted (NULL) so no need for the adapter. If any one has more details on this, please let me know. I am waiting on the UDS, but received the cable already (CX-88). Well, I just read this: Also, remember: UDS-10 uses a CX87 cable, and the MSS uses a CX88 and a gender changer. The difference is that the MSS requires a Null MoDem cable. Argh. So with the 8-bit, I need one of the following?? 8-bit >> 850 >> CX-87 >> UDS-10 OR 8-bit >> 850 >> CX-88 >> null modem adapter >> UDS-10 EDIT: Found this in my parts bins from an ODBC-II car project I did years ago!! So, now just need confirmation if I need the adapter or not. Whew... Thanks! Edited March 18, 2018 by NISMOPC Quote Link to comment Share on other sites More sharing options...

ORDERED! Having issues with Lantronix set-up - been working on it all night. Not to mentioning I'm getting the highest pitch sound from my monitor every time I load Ice-T.

+remowilliams Posted March 21, 2018 Share Posted March 21, 2018 Connected the WiModem232 to my 800XL using a P: R: Connection, prconn.hnd, and ICE-T Using the 9pin to 25 pin cable that came with the P: R: it communicated with the WiModem232 right away, using a standard 9-25 cable I have didn't work. There must be something I've forgotten about the P: R: cable having unique wiring or something. Connected to a few BBS at 9600bps and didn't see any issues. Need to try out file transfer but the BBS's I connected to didn't seem to have any A8 files. 3 Quote Link to comment Share on other sites More sharing options...

So glad to hear you got this working and so simple.Appreciate that you notified me it was available and that I actually ordered it. Just patiently waiting now. I'll be using my 850 interface (ATARI850.HND) and Ice-T. I have a CX-87 DB9 to DB25 cable on the way and already own a CX-88 (null modem) DB9 to DB25 cable, so I should be OK with the connections as well.

+David_P Posted March 21, 2018 Share Posted March 21, 2018 P:R: Connection has the same non-standard serial ports as the 850, to maintain compatibility. Quote Link to comment Share on other sites More sharing options...
+Nezgar Posted March 21, 2018 Share Posted March 21, 2018 P:R: Connection has the same non-standard serial ports as the 850, to maintain compatibility. The ICD MIO also uses the same pinout as the 850 and P:R: Connection. So, it was kind of an Atari 'standard'. Although, I did have an issue with a recently acquired P:R: connection I was playing with the other day, I could only get R2: to work correctly, R1: seemed to light up a bunch of lines solid and wouldn't work... Maybe something with the extra handshake lines... I compared the documented pinouts of all three the other day while trying to get it connected to my Cisco router AUX port configured as terminal server for telnet.

NISMOPC Posted March 24, 2018 Author Share Posted March 24, 2018 (edited) So stoked. Haven't been online via an Atari in over 30 years... Atari 130XE running Ice-T 2.67 via SIO2PC (Respeqt) => Atari 850 => CX-87 Modem Cable => wimodem232 => WiFi router Took very little time setting up the wimodem232 with my WiFi router and was working within minutes. The OLED screen is absolutely amazing and wireless connection... heck yea!!!!!! THANK YOU remowilliams for pointing this producct out to me.
