Today I attached the Elk-M1XSP's to the structured wiring panel and plugged them into the Elk-M1DBH. I also built a Cat-5 wire for the Elk-M1XIN and plugged it into the Elk-M1DBH too.

I decided to locate the Aprilaire 8818 distribution panel on the wall, just below the wiring panel. I screwed it into the wall, leaving enough room for the Aprilaire 8811 protocol adapter which sits between the Elk-M1SXP and the 8818. While putting these components together, I realized that I need to purchase a power supply for the 8818 (why don't they ship the 8818 with a power supply!?!?). I connected the 8811 to the Elk-M1XSP with the DB-9 connector and cable supplied with the 8811.

When I had everything connected together, I powered on the Elk controller and asked it to search for devices on the RS-485 bus. It found all of the components I had hooked up. So far so good!
