Failed to Start the NetLoader

Description

Message text:Failed to put the Device Server into the firmware upgrade mode. NetLoader may not be installed
May appear in:Auto-discovery and  address bookaccess modes; Upgrade function

Details

Firmware upgrades through the network are facilitated by a separate firmware component called the NetLoader . When you click Upgrade button the DS Manager instructs the application firmware of the DS to pass the control to the NetLoader. Before doing this application firmware checks if the NetLoader is actually loaded. This message is displayed when the NetLoader appears to be absent.

Here is why the NetLoader may be missing:

If your DS model is EM100-00/ -01/ -02, DS100-00/ -01/ -02 then this DS cannot be upgraded through the network in principle. The only way to upgrade such a DS is through the serial port (in the COM access mode).
For EM100-03, DS100R-03, DS100B-00 network upgrades are possible, but only if the NetLoader is installed. When the NetLoader is not present the only way to upgrade the DS is through the serial port (in the COM access mode). If you choose the upgrade file that has "SN" in its name then you will be able to upgrade the firmware and install the NetLoader at the same time! From this moment on you will be able to perform network upgrades as well.  Firmware download page at <%WEB%> provides complete info on what file to choose.

Programmer's info:

The DS Manager instructs the application firmware of the DS to switch to the NetLoader by sending Jump To NetLoader (N) command . This message is displayed when Failed (F) reply code is returned.
