3.2 Wiring unit

The wiring unit consists of the AC/DC box (PCA-PB board, AC/DC power supply, power cable
assembly, covers, etc.), power cable set, detector cable and status indicator unit. One detector
can be connected to one wiring unit: It is not possible to connect a multiple number of detectors.
Before connecting or disconnecting the detector cable to replace the detector, it must be verified
that communication between the detector and image capture computer is temporarily suspended
by observing the LED displays on the detector and image capture computer display.
Switching between wireless and wired communication is done automatically by the detector
which detects whether the detector cable is connected or not. However, since the IP addresses
allocated to the detector differ between wireless and wired communication, the detector must be
selected again using the software in the image capture computer. Furthermore, the detector
cable can be switched while the power for both the detector and AC/DC box in ON.
The main functions of the wiring unit are described below.
(1) It supplies power to the detector.
(2) It has an Ethernet relay interface function for wired communication between the detector and
image capture computer.
(3) It has a control line relay function for interfacing with the detector and status indicator unit.
