I'm trying to re-program my MTASR3-200 with a new IP. Every program I use from your website locks my PC up. What program do I use? I have a serial cable with an RJ45 end plugged into its command port. How do I reset the device to factory defaults?

You can use the RASFinder Windows software to configure the box. Here is the link to download the latest software:

You can also use hyperterminal to communicate via the command port. Set hyperterminal to 19200, 8N1 and power on the RASFinder and make sure you see the bootup messages. Once booting is complete, you can type in the word "login" (without quotes), and it will present you with the configuration menu.


Procedure for Recovering RASFinder, Proxy Server, MTASR3, and MTASR1-100 routers:

Download default setup or wizard setup:

1) Connect the PC com port to the command port of the router.
2) Start a HyperTerminal Session and set terminal parameters to 19200, 8, N, 1, and NO Flow-Control (for RF300E and MTPSR3-100, you need to set the baudrate to 57600).
3) Turn OFF and ON the Router/ProxyServer/RASFinder and you will see some messages show up on your terminal screen. If you do not see the messages, then your hyperterminal is not setup properly to communicate with the command port of the router. Check your cable, PC and Hyperterm settings.
4) Once you see the message and are asked to "Press D to Download..", press the letter D as soon as you see the message. Now the Router/ProxyServer/RASFinder will be in the ready mode for download setup and download firmware.
5) Go to the "CALL" tab on HyperTerminal and select "Disconnect" or close and exit hyperterm completely. This will allow Router/Proxyserver/RASFinder windows programs to use the COMM Port.
6) Select the "Wizard Setup" or "Download default setup" icon within the Router/ProxyServer/RASFinder group. The program will prompt you with some setup parameters and then it will download the setup.
7) At this point your boot / fail light is still on. This is normal. Continue to the download firmware update below.


Download firmware update:

1) Repeat steps 1 to 5 above.
2) Select the "Download Firmware" option within the Router/ProxyServer/RASFinder group.
3) Select the 'RASFM31x.BIN' or 'Proxy2xx.BIN' or 'MTASRxxx.BIN' file that shows up in the list of available programs.
4) Downloading the firmware will take some time; please be patient. After the firmware download is completed, the Boot/Fail LED should go off if everything is upgraded properly.

Note: If the fail light is still on, repeat the above procedure again.
