IR Commander Troubleshooting Questions

IR Commander Frequently Asked Questions (FAQ)

My Firecracker doesn't work when my mouse is plugged into its serial passthrough.
Will the Firecracker work if a mouse is plugged into it?
A mouse is a full time device that prevents any other device from using its serial port. This means that the Firecracker software is unable to communicate with the CM17A. You will have to move the CM17A to another port for it to work.

How do I save the changes I made to the labels in the onscreen PalmPad?
Any changes you make will be saved if you exit the Firecracker software correctly. Right click on the onscreen PalmPad or on the taskbar icon and select 'Close.' Click 'Yes' when asked, "Do you want to close the Firecracker application?" This will save your changes and exit the program.

What do I do if the CM17A doesn't fit into my serial port?
On some computers, there isn't enough space around the serial port to plug the Firecracker interface in. If this is the case on your computer, you can try using another serial port, or purchase a extension serial cord.

How do I install the add-on to the Firecracker software?
Once you have downloaded grext.exe simply double click on the file to run it. This will automatically load additional graphics for your Firecracker software.

My Firecracker won't control the TM751 transceiver. What do I do?
In order for the Firecracker software to work, the software must be able to communicate to the CM17A, and the CM17A must be able to communicate to the TM751.

First, make sure that the COM Port selected in the Firecracker software is the correct one for the serial port you have the CM17A plugged into. You can check this by right clicking on the onscreen PalmPad and selecting "Test Communications." Any COM Port displayed in gray is not available for use on your computer. You should also check in the Windows 95/98 Device Manager to make sure that the COM Port you have chosen isn't being used by another device. Bring up Device Manager by right clicking on "My Computer" from your desktop, choosing "Properties" and then the "Device Manager" tab. If you can't tell if you have selected the right COM Port, you may need to contact your computer technical support.

Once you have confirmed that the COM Ports are configured OK, you'll need to check that the CM17A can talk to the TM751. Remember, the House Code (letter dial) on the TM751 needs to be the same as the House Code in the Firecracker software. When testing it's also helpful to plug the TM751 into an outlet in the same room as your computer. Try several times before you give up. If you still can't get it to work, call X-10 technical support at (800) 442-5138.
