6、 Support multi-tuner control switch
DM500 can support the 13/18V satellite switch, you can set up 32 high-frequency information at most. Of course, it also support the polar axis. The other big advantage about DM500 satellite receiver is that DM500 just need to enter the parameter with the remote control directly.
7、 Smart-card reader
DM500 has a smart card reader port, you can see the card's icon. My personal feeling is that it's not enough for the user who is using the car to watch TV programs. There are three reader ports of the Thunder 430XP, which is popular now. DM500 can offer shared key by using the CV12/A2 shared box to decrypt the encryption units. You will see the detail below.
3、Linux Operating System
Linux operating system is an open source operating system. The PowerPC CPU used the embedded Linux system, whose big advantage is you can develop a variety of DM500 application system, which made DM500 be not just a satellite receiver, but can develop many functions.
4 、Automatic scanning
DM500 can scan all satellite transponders automatically. There are three standard scanning mode of operation. Of course, you can scan with the blind-plug-in applications to achieve the blind scanning.
5、 Support for user-defined TV Listings
DM500 can set your favorite channel listings at will and you can delete the channel easily. For example, you can set the Movie, News, Children's sets, and add some other channel.
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.
