INSTRUCTIONS
Setting Up an X10® Multi-Camera System
up, turn it off using your CR12A. Repeat these 
steps for each camera you are setting up. Make 
sure to choose a different Unit Code for each 
camera.
SETUP
Your X10 multi-camera system allows you to control 
X10 XCam2™ cameras from your PC and view 
each camera from the XRay Vision™ software. 
Follow these instructions to set up the necessary 
hardware and software. You should have previously 
installed XRay Vision on your PC before starting 
these steps.
Set Up the Transceiver Module
Make sure you have connected the
Transceiver (model TM751) to a nearby 
power outlet. The outlet you use should not be 
too close to the back of your PC, as 
your PC may create some electrical 
noise that could reduce the range 
of the transceiver. Set the House 
Code (letter dial) on the Transceiver 
to the letter you will use for your 
cameras.
Connect the Firecracker Computer
Interface
The Computer Interface (model CM17A) 
uses wireless signals to transmit X10 control 
commands from the computer to the transceiver 
module included in the kit. Connect the Interface 
directly to your PC's serial port. If 
there is already a device connected 
to this port, unplug it, connect the 
Computer Interface, and then plug 
the other device into the connector 
on the CM17A. Important: Do not 
plug your mouse into the CM17A!
Configure Your Cameras in XRay 
Vision
Run XRay Vision. Right click in the
program window and choose "Settings" 
then "Preferences" from the pop-up menu. Click 
on the "Cameras" tab in the configuration window. 
Click on the "Add" button to create an entry for 
a camera. Click into the "Camera Code" box and 
enter the House and Unit code for this camera. 
Make sure to enter the letter and number without 
a space between them. In the "Comment" box 
you can type a description or name for this 
camera. Repeat these steps for all the cameras 
you set up earlier.
You are now ready to control your cameras from 
XRay Vision. Right click in the XRV window and 
choose "Camera." You will be able to select from 
your different cameras, or tell XRV to 
automatically switch between all of them.

Set Up Your Cameras
Set the House and Unit code on the
addressable power supply (model 
XM10A). All of the cameras you set up will be set 
to the same letter (House) code, and each will have 
its own number (Unit) code. Plug the power supply 
into a free AC outlet. Connect the camera to the 
power supply. The camera should come on and 
you should be able to get the picture on the TV. 
Adjust the antenna so that it points better at the 
antenna of the receiver. When the camera is set
