Suite 200, Draper, UT 84020 • (801) 495-2310 • FAX (801) 495-2255 5 Software Options Two different software applications are available to monitor and configure Mini Rad-DX radiation detectors. 5.1 DX-View Software The DX-View is a PC application used to monitor and configure MiniRad-DX and Rad-DX detectors. Multiple detectors can be monitored in real-time as long as a Rad-DX device is connected to the PC directly and the other detectors are configured to communicate via the mesh network. This software is available for download from www.dtectsystems.com. If you wish to configure your Mini Rad-DX directly using this tool, install the downloaded software and connect the device to your computer using the included mini USB cable. 5.2 DX-Dashboard Setup Tool The DX-Dashboard Setup Tool is needed to initially configure devices in the Rad-DX family to connect to the DX Cloud Server. The DX-Dashboard is the web server application and can be used to monitor and control a MiniRad-DX and Rad-DX network from any smart phone, tablet, or PC. DX-Dashboard runs on either the D-tect Cloud server or the DX Network Assistant (if installed at your facility). You will be asked for your user name and password to allow access to your network. Note: In order for MiniRad-DX devices to appear in the DX-Dashboard software, one Rad-DX device in the network needs to be connected to the network via Wi-Fi or Ethernet. 6 Maximizing Battery Life The MiniRad-DX battery can last up to 130 hours with the mesh radio turned off, the GPS capability turned off, and displays set to sleep after one minute. Turning up screen brightness, keeping displays on longer, turning on the mesh radio and turning on GPS will require more frequent recharging. Monitor the battery icon in the upper left corner of the front display to determine when it is time to recharge the MiniRad-DX. 7 Recharging the MiniRad-DX The MiniRad-DX is recharged through a USB connection. Either a USB port on a PC or a USB wall charger can be used to recharge the MiniRad-DX. 8 Stand-Alone Operation The MiniRad-DX can operate in a stand-alone mode with information displayed directly on the device’s LCD and OLED screens. Options for the MiniRad-DX, such as screen brightness, screen sleep timers, and radiation units, can be set up using the following process:

Battery: The battery icon is split into 5 segments. Each segment represents 20% of the total capacity of the battery. This icon will change to a battery symbol with a lightning bolt when the MiniRad-DX is plugged into a USB port. This indicates that the device is charging. Mesh Network: The mesh network symbol indicates that the MiniRad-DX is connected to a greater network of devices in the Rad-DX product line. For more information about the MiniRad-DX’s network capabilities, see Section 9: PC Connection and Network. USB: The USB icon indicates that the MiniRad-DX is communicating directly with the DX-View configuration software. See Section 9 [note: need to link this section number]: PC Connection and Network for more information about the networking capabilities of your MiniRad-DX. GPS: The GPS symbol indicates that your MiniRad-DX has determined its location. GPS must be turned on to acquire a location. Time: The current time can be displayed in the 12 hour or 24 hour format.

The timers for the two screens can be set independently of one another. The options are as follows: 30 seconds, 1 minute, 5 minutes, or never. Enabling sleep modes allows for the device to function longer between charges.

Typical use would have them wearing the device on their belt. To preserve battery life, the front screen could be set to 1 minute of inactivity before shutting off and the top screen could be set to never sleep. This allows for continuous status monitoring through the top screen and turning on the front screen only when further information is needed. Regardless of the sleep settings, the MiniRad-DX will alarm if radiation above the set threshold is encountered.

For Wi-Fi and/or Ethernet based communication, see the D-tect Cloud Network and D-tect Network Assistant sections that follow. Figure 10: Basic PC Network D-tect Cloud Network: The D-tect Cloud Network is an easy method to control and monitor a network of detectors in the Rad-DX family. It also allows the detectors to be monitored via smartphone, tablet, or PC. Setting up your MiniRad-DX unit within the Cloud Network will require a PC with an internet connection and a DX Link USB radio (or Rad-DX) to act as an intermediary between the PC and MiniRad-DX. All information sent over the Cloud is SSL encrypted. Figure 11: D-tect Cloud Network DX Assistant: The DX Assistant appliance allows MiniRad-DX and Rad-DX devices to operate behind a firewall that blocks access to the internet. The DX Assistant is a computer that includes all the software needed to control and monitor the network of detectors. DX Assistant software can also be installed on a virtual machine on a local server.
