Put simply, DM500 is the combo product by a satellite receiver and an inside-linux operating system. As a fan, seeing the data of DM500's parameter table may still be confused. So let's explain it step by step.
1、Power PC CPU
DM500's CPU chip is called the PowerPC, but we can't just translate it into the CPU with power-pc computer by literally. This chip began to develop from 90's by IBM, Motorola, Apple. The full name is Power Optimization With enhanced RISC, which is widely used in network equipment and consumer devices. The RISC chip has now grown to more than 2GHz, but PowerPC is still 250MHz. Germany Dream Company applied 300MHz’s PowerPC with DM7000 after DM500 and the DM8000's series HD models are used AMD's higher performance CPU.
2、Indicator Light
The two status of indicator light are green-Working and red-Standby. What should take into consideration is the infrared remote sensor of DM500 is also inside the window, so it's better not be blocked by objects, or the remote control isn't sensitive.
About the indicator light, there are something you also should notice. It's the network logon indicator light, which not set on front nor rear, but inside the case. You can see it through the vents, on the right side of the body. There are two green lights if the network is good.
