Q: When installing firmware, does it take less time in “manual download and update” compared to “update via SST”?
A: It depends on the number of devices to update firmware.
When updating the firmware on a device, it takes more time in “manual download and update” compared to “update via SST” (It depend on network environment.).
As for the time to update firmware to multiple devices, “manual download and update” takes less time compared to “update via SST” because updating the firmware to multiple devices can be executed simultaneously.
When the network line of the user is slow, update via CDS becomes slow in comparison with the SST. Because speed is displayed by a communication test, You refer to it.
As for the aim of the downloading time, transmission rate is 6 or 7 minutes in the case of 1000KB/sec. (There is a difference in a device and a version of Firmware, accessories and the quantity of the language files).
No.3
Q: How can we confirm that the firmware is properly updated after “UGW-linked download and update” done?
A: You can confirm this in E-mail or the Device List on UGW-linked screen.
E-mail to notify firmware update will be sent from CDS server to the addresses set as destinations at the time of distribution setting to notify update completion.
On UGW-linked screen, search the device of your interest on [Select Device] screen to find the distribution status per device as shown in the search result.
No.4
Q: In the course of “UGW-linked download”, what will happen if the user downloads the firmware before the service technician update the firmware downloaded with “UGW-linked download” before?
A: The previously downloaded firmware in the method of “UGW-linked download” will be overridden by the subsequently downloaded one.
This is because only one downloaded firmware can be held on the device.
The firmware downloaded in the method of “Service mode-linked download” and “UGW-linked download” can be checked/deleted from User mode, but cannot be updated, so it cannot be updated by the user unnoticed by the service technician.
No.5
Q: What happens if the user registers another distribution schedule when the distribution schedule has been set in “manual download and update”?
A: The distribution schedule subsequently registered by the user will override the existing schedule. This is because only one distribution schedule can be held. Any existing distribution schedule is deleted and the newly registered distribution schedule is made valid.
