- SoC: Lantiq VRX220 (MIPS 34Kc @ 500 MHz)
- RAM: M14D5121632A (DDR2 SDRAM, 64 MiByte)
- Flash: Winbond 25Q64 (Serial NOR Flash, 8 MiByte)
The device is running a Linux kernel V 3.10.12, Bootloader is U-Boot.
The connector for the serial console is labeled "JP2" (near the serial flash)
Settings are 115200 Baud, 8N1, Xon/Xoff
Pin 4 = GND, 3=RxD, 2=TxD, 1=? (pin 1 not tested yet, I assume Vcc, but not needed)
WARNING: signal level is 3.3 volt!
Debugging information can be accessed via http://192.168.5.1/debug.htm On this page, you can also enable a telnet server.
The OS appears to be based on OpenWRT anyway, also see https://openwrt.org/toh/netgear/dm200
I measured about 350 mA on the DC side (which makes about 4.2 Watt), no big difference whether ethernet plugged in or not, and also no big difference whether DSL synced or not. I have to admit, that my multimeter is NOT true-RMS, so it might not be that accurate (and it's the reason I measured the DC side). My old swisscom router consumes about 410 mA.
