Accessory Project for powering air solenoids
Jim Agnew:
Thank you, that’s what I needed. I’m I correct in assuming output equals the terminal number on the AM-1?
G8B4Life:
Yes, with additional information.
Output 1 and Output 2 are Motor 1
Output 3 and Output 4 are Motor 2
Output 5 through Output 8 are Output 5 through Output 8.
Look at the AM-1S or AM-2S manual under Wire LED's or Wire Light Bulbs to see how you should wire the solenoids. I don't think there's any reason you probably couldn't use the motor outputs as well as long as the solenoids aren't polarity sensitive.
Also, the max current the AM-1 is rated for isn't specified but the max current the AM-1S is rated for is only 400mA continuous combined across all outputs; just something to be aware of.
Another thought, if it doesn't quite work out because there's not enough grunt to power the solenoids directly:
* You could use the turnout program in the AM-1 to drive latching relays (push the button to turn on, push the button again to turn off) to drive the solenoids.
* You could drive normal relays from the project you write to drive the solenoids.
It's more money etc but it could be a last resort to provide enough grunt.

Couple more questions, if you don’t mind.
Once the project is downloaded, is it no longer available for editing and must be recreated from scratch?
I’m getting a message that my project name can’t be associated with a picture?

No, it should be available in RailPro Assistant so you can download it again and again, until you delete it. I'd suggest giving the RailPro Assistant manual a look though. The part dealing with custom accessory projects starts on page 39 but you should find your accessory project by clicking the Accessory Project button in the section of the RPA screen titled "Select here to load file from this computer to hand held controller". You can then use the "Select Option..." buttons to edit, copy , delete etc.

When your designing the project in RPA, the picture you type in must exist in RPA as well for it to show, so following my example a picture named Little Gulch Nth End would have to exist in RPA for it to show on the designing screen. This has no bearing on when the project is loaded into the accessory module, you'll have to upload the picture you want to the AM-1 and set the picture the same as you do for a LM.
I'm presuming that you've downloaded the Accessory product program to the AM-1?

When I try to edit the project, I’m getting a message “file not on this computer”. I’ve recreated the project and still get the same message.
Very frustrating, but I’m going to keep trying until I get it correct.
I did manage to load the picture, but I’m having the same problem loading the picture to the project.
FWIW, I’m on a windows 10 HP laptop.
