RTR-4 Portable Digital X-Ray Imaging System--Operator’s Manual Supplement The Power/Transceiver unit (Figure 3-2) has three functions: • • • Provides power to the imager previously supplied by the controller (in the CU-4 case) or the external power supply (in the notebook case). Facilitates wireless communication between the controller and the imager. Sends the wireless signal from the imager to the x-ray source for firing x-rays.
RTR-4 Portable Digital X-Ray Imaging System--Operator’s Manual Supplement The transmission frequency of the Power/Transceiver when communicating with the imager is near 2.4 GHz. This communication is done between 2.4000 and 2.4835 GHz, is spread-spectrum and frequency-hopping, according to the IEEE-802.11b-1999 standard, and is further encrypted to minimize snooping or spoofing.

4 Wireless Option Setup Introduction This chapter describes the tasks uniquely required to prepare the RTR-4 Wireless Option for operation to be described in Chapter 5. Routine RTR-4 physical setup procedures are described in Chapter 2 of the RTR-4 Operator’s Manual except for the Wireless Option Setup tasks described here.
RTR-4 Portable Digital X-Ray Imaging System--Operator’s Manual Supplement STEP 4-2 ACTION 2 Screw on the two antennas (one shorter, one taller) to the Power/Transceiver as shown below: 3 Insert one end of the Power/Transceiver’s “X-Ray” coaxial cable into the red-labeled “X-Ray” jack on the right-hand end of the Power Transceiver as shown below.
