System Description, Setup, and Quick Start RTR-4 Operator’s Manual • The imager may use other external power sources between 12Vdc and 24Vdc such as vehicle power. RTR010 IMAGE TARGET AREA ORIENTATION INDICATOR Image Target Area The active image area is indicated on the face of the imager. This is the area that will be displayed on the controller PC.
RTR-4 Operator’s Manual System Description, Setup, and Quick Start Power-on Delay Timer The imager is equipped with a rotary switch that allows setting a 0 to 3 minute delay between turning on the imager power switch and the application of power to the imager. The switch positions provide 20 second interval settings up to the 3 minute limit. Use of this switch permits operating personnel to leave the immediate area before electromagnetic energy is applied near a suspect package.
System Description, Setup, and Quick Start LED RTR-4 Operator’s Manual INDICATION TEMPERATURE FAILURE, battery is too hot or too cold for safe charging. The battery should be brought to operating temperature. Red Green On steady. Off. FAILURE, battery is physically damaged, do not use, discard battery. Red On. Green On. Red FAILURE DURING INITIATION If the red LED light up when the charger is plugged in, the charger is not ready for use. Contact your nearest dealer.
RTR-4 Operator’s Manual System Description, Setup, and Quick Start The functions located on the Imager control panel are as follows: CONTROL OR INDICATOR Power On-Off Switch Power On LED FUNCTION Turns on the imager power for both internal battery and external power operation. • Green and on steady when powered by battery. • Amber and on steady when powered by an external source. • Flashing green when power-up delay is selected, with last five seconds before power on rapid flashing green.
System Description, Setup, and Quick Start RTR-4 Operator’s Manual XR200 X-Ray Source The RTR-4 system uses the Golden Engineering XR200 X-ray source. This is a pulsed 150kV unit with a 40° beam angle. This unit produces extremely short bursts of X-rays capable of penetrating several centimeters of most materials. The source is equipped with a keyed power switch to prevent the uncontrolled emission of X-rays. The source is battery powered using a rechargeable battery.
RTR-4 Operator’s Manual System Description, Setup, and Quick Start • 50m (164ft) cable on a reel, passes communications and image data signals between the controller and the imager. • 3m (10ft) X-ray source control cable connects the X-ray source to the imager. Transport Case The RTR-4 is protected during transport and storage by a rugged impact-resistant plastic transport case with fitted foam inserts.
System Description, Setup, and Quick Start RTR-4 Operator’s Manual RTR-4 Standard Wireless Configuration Wireless Option The RTR-4 Wireless Option is an alternative to connecting the controller, X-Ray imager, and XR200 X-ray source with cables. Wireless operation simplifies system setup and use by eliminating the signal cables and provides greater controller to target distances. The Wireless systems adhere to the frequencies and protocols of the WiFi, IEEE-802.11b standard.
RTR-4 Operator’s Manual System Description, Setup, and Quick Start • 2.4GHz screw-on transceiver antenna (ANT 1) for the imager transceiver provides signals for communication with the controller. • 418MHz or 433MHz screw-on transmitter antenna (ANT 2) for the imager transceiver provides signals to the X-ray Receiver. • Optional source transceiver with short antenna and connector cable for alternate X-Ray sources.
System Description, Setup, and Quick Start RTR-4 Operator’s Manual Setting up the RTR-4 There are two setup configurations for the standard RTR-4, the wired configuration and the wireless configuration.
