Thank you.. The normal usb cable is coming with 5v (http://www.bifelectronic.com/images/PL2303HXcable.jpg) but this one is 3.3v how can we solve that.

Take good look at the link I posted. Right next to the photo of the header, TJ writes:

Code: [Select]
The voltage levels are 3.3 volt CMOS (Complimentary Metal-Oxide Silicon). I connected the serial port to a PC using a CMOS to TTL (Transistor-Transistor Logic) MAX3232-based converter and a serial-to-USB MCT-U232-based converter.
You can get one on the net, e.g. ebay, for a few quid. I use one from sparkfun electronics and have had no problem with it.

You only connect the Tx, Rx & Gnd leads to the PCB. The +5V lead is left unconnected as the PCB is powered by its own PSU.

There are many TTL to USB devices available.

Got the cable. It detected as 'Prolific USB-to-Serial Comm Port' Thank you all for the help. Hope I can unbrand the eFiber modem with help of this cable.
Downloaded the new firmware from Zyxel.
Connected 3 cables ie TX, RX and Ground with external power connected
Via Putty Change Serial Line to COM3 and Speed to 115200 with serial connection but nothing is showing after connect.

  In windows you need to install the right driver to get most "usb to serial" to work.

Press the space bar a few times at the beginning of boot and it will drop to the CFE command prompt.

From cfe in windows you can unlock it. Read the instuctions in first post.

You can flash the firmware from Linux, a few posts back tells you how to do that:


apt-get install screen lrzsz

screen /dev/ttyUSB0 115200

Then press Ctrl-A followed by : and type:

exec !! sx yourbinary.bin

This will send the file to ttyUSB0 over xmodem protocol

Thanks for the reply, But in linux I cant able to connect using screen command.
I tried using ExtraPutty in windows and I can able to transfer the file using xmodem and xmodem 1 but in both case the transfer stop in between.
If you could able to help for connecting the device in linux then I can able to follow the reset of the steps. Thanks...

I don't know why it stops half way in windows, strange.

In some Linux you need to do

sudo screen /dev/ttyUSB0 115200
