To Access the Wires-X Network on a Yaesu FTM400D
First let's set up your radio for Wires-X Network access. On our Repeater system we use DG-ID of "1" to operate Wires-X Network. There are 2 different ways to do this. One way is to set the DG-ID to TX-1 as we showed you to connect to different repeaters together. This radio has a trick built into the software to do that automatically. Follow the menu options to set the radio up to do this automatically.
Select the Wires X menu item. And select item "5" DG-ID.
Hold down the DISP/SETUP Button for 2 seconds and you will see the SETUP MENU.
Change the DG-ID from "Auto" to "01". Hold down the DISP/SETUP Button for 2 seconds to exit the Menu.
Now that your radio is set up to use Wires-X through our repeaters, Let's do it!
Hold down the  the Red DX button for 2 seconds.
See the different display? Just like that you are in Wires-X mode! See towards bottom of the display? This tells you what room you are in.
If you hold down the Red DX button for 2 seconds you will exit the Wires-X mode. Give it a try, go back and forth.
Now that you are in the Wires-X mode, where do you want to go? Well probably a Wires-X Network Room. There is a couple of ways of doing that let's look at that now:

On this radio the only way to enter a Room by ID # is by using the microphone.
Without pushing down the PTT Button:
Don't do it!
Hold down the "#" button till the screen changes and the radio beeps.
Now we touch the microphone number buttons to enter the room number.  You can find the room numbers at:

Let's enter
21636 for the Texas-Nexus room.
Now quickly press the "#" button on the microphone.
After a couple of seconds you will see this Screen showing "TEXAS-NEXUS" as the room you are in. When someone talks in the room you will hear it. And when YOU transmit on your radio and talk the people in the room will hear you.
To disconnect from the room push the "
*" button on the microphone for 2 seconds and it will disconnect you. Please disconnect from a room when you are done using it.
Here is another way to get to a room using a name instead of a room number. This way will use the screen instead of the microphone.
First make sure you are in the Wires-X mode.
Select the white downward arrow in the middle of the screen.
Select the "Search & Direct" on the screen.
Using the different screen buttons type out "TEXAS" then hit "ENT".
This will send a query to the Repeater asking about all the Rooms with the word "TEXAS" in it. On the screen scroll down to the one you want using the Knob on upper right of the radio, then press in the button with your finger.

The next screen you see will show you that you are connected to the "TEXAS-NEXUS" room. Hit the "BACK" button to get back to the mail screen.
To disconnect from the room push the "*" button on the microphone for 2 seconds and it will disconnect you. Please disconnect from a room when you are done using it.

There are many more things that we could go on and on about. But at this point I will let you explore what we have done thus far - Have FUN!
