Some may have followed my mass deployment of the $6 DMX controllers. I started looking a little closer and two things popped out - one is that there is a WS2801 chip on there - why would there be one in there? Second is that it uses a Texas Instruments RS485 chip, not some cheap Chinese knock off.
Attached is a datasheet for the TI 485 chip and so photos.
Here is a video of 46 of them on a 250ft cable with 90 splices:
