Aukey PS-W1 Scanner Interface

This is a pure javascript implementation of a very basic scan library over WiFi for the Aukey PS-W1.

Requirements

You must have imagemagick and graphicsmagick installed

On OSX, this is as easy as brew install imagemagick graphicsmagick.

Scanner Setup

As of now, the library only reads scans in one by one; a scan daemon, if you will.

The scanner itself must be in WiFi mode connected to your network. To do this, you have to download the DirectScan for iOS off of iTunes or DirectScan for Android off of Google Play. If you simply cannot use a phone to do a one time configuration, then use Google's Arc Welder and obtain the APK by using this site.

Once you have acquired the appropriate DirectScan app, you must put the scanner in WiFi mode and wait for the icon to turn blue (indicating it's ready). This may take up to 2 minutes.

Connect to it directly (the SSID should be along the lines of DIRECTSCAN, etc) using the password in your manual (the default is 12345678).

Once connected, open up the DirectScan app and let it discover the scanner. Select it from the list, and then go to settings.

Once in settings, make sure to adjust your scan settings how you'd like (i.e. scan DPI and color/BW) and then go into wireless settings. Leave the access point settings alone and only change the repeater settings to reflect your local network settings. Keep in mind the app does not allow you to input manual SSID settings; your SSID will have to be (at least temporarily) publicly broadcasted.

Make sure to hit OK and disconnect from the scanner. Let the scanner reconnect to your network.

If the scanner connects, but is only showing up in the peer table with a MAC and no assigned address, you probably typed the password wrong. If you are sure you didn't, you may need to reserve an IP in the DHCP settings of your router. This thing's WiFi capabilities are quite... lackluster.

Once the device has connected, you'll need to get its IP address. This is what you pass to the constructor of the PSW1 class as the first argument.

Usage

See test.js. It can't get any more simple than that.

Format

The format returned in the scan event is a buffer containing a JPEG image. Since the scanner actually does size detection, it should already be the correct size. This library doesn't care what is done with the image; it simply serves it to you.

License

MIT license. You're probably familiar with it.
