Good evening everyone

I'm working on our church smoker and I'm going to be building it similar to how I did my. Bradley only much larger.  Anyways I have a new n1050 PID and I'm excited to try the programming through USB but apparently I'm not smart enough to get it wired right.  Which terminals do Iand do and D1 from the usb connector on the PID itself? I've looked through all the manuals and I'm coming up short still.  Thanks everyone!

I'm so dumb.  I saw the wiring and the usb adapter in the box and assumed it was needed.  Didn't even see the micro USB on the side of the PID.  I'm in it and playing now lol!  Side note, what is that for? It's not for the 485 connection is it? That should be serial unless I'm mistaken.

N1050-B (PRRR) comes with two communication ports. One the RS485 port located on the back (screw terminals), including D1, D0 and GND. One is the micro USB port located on the side. Both RS485 and micro USB communications are serial.

Micro USB port is recommended for temporary use. RS485 port is recommended for long time monitoring.

For RS485 wiring, connect D1 to positive on your USB adapter port. Connect D0 to negative to negative on your USB adapter port. GND is not necessary.

I think i realized what i did.  I had it hooked to rs485 but when I was in quick tune I was under the usb tab. I'll play with it some more and report back but I'm pretty sure that was my problem. 

[Hutch]

Well still cant get a rs485 connection.  Not a big deal as USB will fit my needs, but now its bugging me I cant get it.  I'm sure its just a setting issue.

So a couple questions on the rs485.  Does it need to be powered on or will it power like the USB option does? 

Second.  I'm using the USB adapter I got from auberins direct to the PID.  I saw novus offers an adapter from usb to 485.  Is that necessary?

1. For RS485 communication, you need to supply external power to the controller to power it up, so it can communicate. RS485 cable doesn't supply any power to power up the controller.

2. For USB communication, USB cable will power up the controller. But the controllers' internal output will not receive enough voltage from the USB cable to trigger. So if you want to temporarily change any settings via USB port, you don't need external power to this controller. Otherwise, you need to supply external power to this controller.

3. For RS485 communication, unless your computer has native RS485 port, you have to use an external USB-RS485 adapter. You can use the one supplied by Auber, or you can use the one offered by Novus, or any other RS485 adapters on the market.

Thank you very much! Cleared it up perfectly! I'm sure I'll have a million more questions as this project goes along, thank you for being so quick to help out!

Am I missing something on the software to change the com port when using 485? I got it setup on the bench temporarily just to play some while I'm waiting on parts.  Got it wired up right, checked it numerous times.  All my baud rate, parity, and stop bits match what I programmed it to.  But for some reason when I click the drop down for com port it just gives me port 3 for the options.  Am I doing some wrong still?

So is COM3 from your USB adapter, or from a different port on your computer? You can open your device manager from your Windows and check your current connected COM ports.

You can remove your USB adapter then check device manager and see how many COM port you had. Then plug in your adapter, and check again. If there is no new COM port generated, you computer cannot read your adapter so you need to manually install the driver for your adapter. If you are using the USB adapter from Auber, you can download the driver from Auber's N1050 listing page.

[Hutch]

Got it finally.  Had to manually install the driver.  I can monitor it over 485 but not program.  That's normal right?

You should get a hardcopy quickguide in your order. Please check that document. If you lost it, please find it on Auber website. Please follow the steps in that document so you will see ramp soak function.
