The Device Monitor Logic Object checks for the presence of any specified Soundweb London device, Crown amplifier or any other HiQnet device on the network which exists within the design. The output of the device monitor will be high only when it detects the presence of the device and will be low if the device either drops off the network or is switched off. The device monitor provides a logic output used to drive indicators, presets or other logic objects. One Device Monitor is required for each device to be monitored. Note that when a design is being loaded, the output of the Device Monitors will be low (indicating no connection) until the device discovery process is complete for each monitored device.
Use the properties to enter the HiQnet node address of the device to be monitored. There are 2 methods - by device name, which is more convenient and by HiQnet address which is more flexible.
Use Device Name: Select YES to choose the Device Name to monitor. The device must be included in the design for its name to appear in the Device Name list. The HiQnet node address of the device will automatically be entered if the device is on the network. If the device is not on the network then a HiQnet node address will be generated. Select NO to manually enter the HiQnet node address of the device to be monitored. This is useful if the device you wish to monitor is not currently on the network and or design.
Device Name: Active when "Use Device Name" is set to YES. The name of the device to be monitored can be selected. Only devices included in the design will have their names on the list.
HiQnet Node address: Active when "Specify Named Device" set to NO,. Enter the HiQnet node address of the device to be monitored. This can either be in hex in the format 0x1234 or in decimal in the format 1234. If no node address or name has been entered for the device to be monitored, the output of the device monitor will indicate that no device is connected.
Poll Time: Sets the frequency at which the Device Monitor will send out a message to the given node to determine if the device is present.
Timeout: If no reply is received from the device within the time set by Timeout then the logic output is set to zero. Timeout must always be set to a value greater then the Poll Time.
TEST Override: This only applies to simulation. Set to "Normal", the output of the device monitor will be low whilst the device is offline. Set to "Force Output High", the output of the device monitor will be forced high whilst the device is offline.
