Tripp Lite Keyspan High-Speed USB to Serial Adapter, PC & Mac (USA-19HS) https://www.amazon.com/dp/B0000VYJRY/ref=cm_sw_r_cp_apa_yoGKBb3XE45Q6

This one works with windows drivers out of the box. USB cable is removable so you can make the cable as long as you want plus the length of the serial cable.

> If I get a serial to usb converter for a more permanent setup, do you think that will work?

The potential for issue is that many of the cheap USB-232 converters are "loose standards" converters... may work on many modern things, but fail on items that are standards-stringent. I used to build / program automated equipment (controls engineer) and would run into this in plants where techs would try and talk to PLCs or PLC-related gear with cheapo converters. As it is, the stack on my dynojet uses a 232 connection and it has to also be the tight-standard style of converter. This unit should work, if any will: https://www.amazon.com/Tripp-Lite-Keyspan-High-Speed-USA-19HS/dp/B0000VYJRY/

Keyspan USB-to-RS232 is the best USB-232 adapter I've ever used. It is a little pricey, but worth it.

If a cable doesn't say "crossover" then it's highly, highly likely to be a straight through cable. I'd be astonished if the cable you linked wasn't straight through.

For console ports, I've typically used the keyspan adaptor as it has consistently been the one that has given the least problems with hanging up or failing to paste large configs in. You will need to get a blue console cable to go with it.

I've tried other usb to serial adapters, and this works the best for a combination of rj45 and db9 cables:

I use a Keyspan: http://www.amazon.com/Keyspan-USA-19HS-Hi-Speed-supports-Sequence/dp/B0000VYJRY

I've had it for 4 years and not had any trouble out of it.

We use this one at work -

Keyspan serial adapter 4Lyf

Is there an option on amazon? This website seems to be closed for the next month or so.

Something like this?

I recommend this USB to Serial adapter and then you can use the correct 9 pin to 8 pin serial cable for the MicroLogix.

I kinda want to avoid adding more interfaces on my chain.

What about this adapter? A USB to RS-232 adapter fits into the 9-pin AES/SPDIF outlet on the preamp. Would that work?

Keyspan USA-19HS. Been using it for years... Love it. Works in Linux / Mac too if you're so inclined.

As others have pointed out, you need a USB to Serial adapter, not an Ethernet adapter.

I would stay away from anything using a Prolific-branded chipset, which seems to be used in the cheap ones. The drivers tend to be buggy as hell and crash the host OS frequently. I personally use a Tripp-lite USA-19HS, which is based on the TI3410 chip, and have had zero issues with it. https://www.amazon.com/Tripp-Lite-Keyspan-High-Speed-USA-19HS/dp/B0000VYJRY I've also heard the FTDI chipsets work quite well.

No no no, you misunderstand. I wasnt using a USB mouse.

When i was testing my Serial mouse i used a usb adapter to test on my main computer (ie, giving my primary computer a temporary serial port).

Both mice i have i got here. I got 2 of them, so they are exactly the same.

And i dont remember having this much trouble getting mice to work in the 90's lol. And this a DX4-100, but i think the board is out of a gateway computer. (tho back then i dont think it would matter too much).

TL:DR; Press <RETURN> after IN#2; you should see IMMEDIATE input on the //c. You CAN use lower-case. You may need to select File > Serial Config > Apple //c ImageWriter Cable option. Try a different USB-DB9 cable if after #Troubleshooting (below) doesn't work.

---

AppleWin developer here -- I just went through this exact same issue this week having recently moved and started unboxing my Apple 2 Lab these past few weeks. Sadly I didn't pay attention to the exact ADTPro setup I had before so I was forced to start over from scratch. In the end this actually worked out since I never documented what I did before so here is an opportunity for me to do this now -- and you get the benefit. :-)

Requirements

• MacBook Pro (MBP)
  
• OSX (I'm running 10.10 but version shouldn't matter)
  
• Apple //c
  
• Serial Cable DB-9 (Female) to DIN-5 (male) null modem cable
  
• USB to RS232 DB9 (male) serial adapter
  
• ADTPro 2.x
  
  

  Caveats
  

  
  NOT all USB-DB9 serial cables work!!! Of the three I have only this one works:
  
  

• IOcrest USB 2.0 to RS232 DB9.
  
  These ones do NOT work:
  
  
• Sabrent USB 2.0 to Serial (9-Pin) DB-9 RS-232
  
• Tripp Lite Keyspan High-Speed USB to Serial Adapter, PC & Mac (USA-19HS) -- Note: I believe this one might work -- as I see the serial port with the with provided /Applicatons/Keyspan Serial Assistant. You need to install the kernel driver and reboot OSX (macOS). HOWEVER, every time I plug it in the mouse and OS freeze. You are forced to hold down the power button reboot. :-/
  
  I'm not sure if the serial cable being a null modem is a factor or not.
  
  

  Solution
  

  
  

1. Make sure the serial cable connected to the port on the floppy drive side. The serial port is on the opposite side of the power supply on the back of the //c. NOTE: You'll see a 2 <phone icon> engraved above the serial port.
   
   
2. When you plug in your USB cable and start ADTPro you must see it listed under File > Serial Configuration. For me it was /dev/tty/usbserial.DN000MLG4 but this will vary depending on which brand/model you have. Check your manual for details. Also, I have:
   
   

• Speed: 19,200 (Note: You CAN use 115,200)
  
• [x] Apple //c w/ Imagewriter cable <-- This was THE key for me.
  
  

3. Press the Serial button.
   
   
4. Select the menu Bootstrapping > ProDOS > Speediboot
   
   
5. The docs for ATDPro are missing an essential keypress as it is implied. On the Apple //c side you MUST press RETURN after IN#2:
   
   IN#2 <RETURN>
   <Ctrl-A>14B
   
   
6. Lower-case DOES work!
   
   
7. When you press Ctrl-A the cursor will change to a question mark ?. If you don't see this then the serial card is NOT active.
   
   
8. When press type B the cursor will change back to the regular checkerboard glyph. You CAN press <RETURN> after the B as well but it isn't needed like the first one after the IN#2.
   
   
9. After pressing OK within ADTPro you should immediately see the CALL -151 and hex input on the Apple //c. If ADTPro sends the file (~30 seconds) but there is NO input on the Apple //c side then your connection is working. See the following Troubleshooting section.
   
   

   Troubleshooting
   

   
   

• Physical verify the USB-DB9 cable connection is solid. My USB-DB9 adapter has a red LED when hooked up to the MBP -- the other lights turn on when actual sending.
  
• Serial config: Lower the speed to 19,200 until you verify the higher speed works
  
• Serial config: Toggling the Imagewriter option
  
• Serial config: Verify you are using the correct /devdevice
  
• If you have exhausted all other options try another USB-DB9 cable
  
  

  Models
  

  
  I have the following Apple //c models in my Apple Lab. I've tested two of them:
  
  | Version | Works |
  |:---|:---|
  |255 (Original) | Yes |
  | 0 (3.5 ROM IIc) | Yes |
  | 5 (//c+) | ? (Haven't tested) |
  
  NOTE: You can find which ROM version your //c is via:
  
  ? PEEK(64447)
  
  Good luck!
  
  Edit: Replaced //c+ pic with //c one.

Get one of these, stick with the old DB9 cable.
