Show Tab in New Window (to view multiple functions or devices simultaneously)
To use this function, first select a device, then select one of the available tabs. Then use Show Tab in New Window, which moves the selected tab into a window of
its own. The main window will then revert back to the Description tab.
Show Device Alternate Names (to see alternate names in the device list)
Example: Thermochron instead of DS1921G-F5 to the right of the ROM ID
Tools
Pick Adapter (to change the communication port and 1-Wire port adapter)
Opens a new window for selecting one of several 1-Wire port adapters, port type, and port number. For more information see application note 5057,
"
," section How to Change 1-Wire Adapters and Ports.
XML Tagging (to load device tags that can be displayed in the device list)
Opens a new window to select the file that holds the XML tags of the devices in use. See application note 158,
," for tag specification
and how to create tag files that are compatible with the OneWireViewer.
1-Wire Speed (to select the preferred 1-Wire speed)
Allows selection of standard speed or overdrive speed. Most 1-Wire devices support both speed modes. To use overdrive speed, the port adapter must also support
overdrive. If overdrive is selected and the port adapter does not support overdrive, an error message will appear when trying to access an overdrive-supporting 1-
Wire device.
Device Poll Rate (to set the frequency at which the 1-Wire net is searched for devices)
The rates are 1s, 5s, 10s, 30s, 1min, 5min, and immediate poll. The typical value is 1s, which yields the fastest response.
Help
About (displays the version numbers of the software components that comprise the OneWireViewer)
Opens a window that displays: the site from which the source code of the 1-Wire API and OneWireViewer can be downloaded; the API version; the version numbers
of the various viewers; and the location of the onewireviewer.properties file on the local hard drive. The OneWireViewer is provided as a source code example in the
Viewer Window Areas
Device List
This is the area that displays the ROM IDs of devices on the network and the device part numbers/names. The 1-Wire Search Mode controls whether a device is
included in the list. Devices that arrive on the network are appended at the bottom of the list. If XML tags have been defined (see the section Viewer Menus, Tools,
XML Tagging above), the device list shows the tags instead of the part numbers/names. In addition, only the functionality associated with their tags is exercisable.
Below the device list, the total number of devices on the network and the type of port adapter are displayed. In this example, the adapter is a DS9097U. The { }
brackets around the adapter name indicate that it uses a native TMEX driver.
1-Wire Search Mode (affects the contents of the device list)
Show Normal Devices
When checked, the list shows all devices on the network.
Show Alarming Devices
When checked, the list shows only devices that respond to the Conditional Search ROM command, e.g., because of an alarming condition.
Show Chain Mode Devices
When checked, the list shows only devices that support the Chain Mode. This feature allows detecting the physical sequence of all the devices in a linear network
that are wired for Chain Mode. An example device is the DS28EA00 1-Wire digital thermometer.
Pause All Searching (to stop/restart searching the network for arriving/departing devices)
When checked, the 1-Wire network is no longer searched. This minimizes the communication traffic on the network (e.g., to facilitate catching events with an
oscilloscope), and freezes the content of the device list. An error message will be generated if one selects a device that has departed from the network. With the
searching paused, one cannot access devices that have arrived because they are not included in the device list. To end the pause, check Show Normal Devices.
Tab Area
Once a device is selected, the Description tab appears with a short description of the device. Depending on the device, additional tabs may appear that provide
access to the applicable device function viewers. See the Supported Devices table below for a list of devices and applicable device viewers.
