4.28.4 Activating the Download Function using the Software
This requires that the terminal is placed to the download mode by activating an I/O
mask and writing a ‘1’ to the system variable IntEraseEprom.
In the event that you have decided not to use the system variable IntEraseEprom,
the old variable definition must be erased with the user-mode switch S4. This will
require strict adherence to the routine to be executed. Subsequently the terminal
will automatically activate the download operating mode.
4.28.5 Activating the Download Function using the Hardware
If the system variable responsible for erasing the Flash memory can not be activa-
ted in the masks or is not available at all, the Flash memory can still be erased by
switching the mode selector switch to a defined position. This will cause the termi-
nal to activate the download mode.
Switch position to completely erase the Flash memory:
S1 ON
S5 not used
S2 not used
S6 not used
S3 OFF
S7 not used
S4 ON
S8 not used
Fig. 26: User-Mode switch
The following message is displayed once power has been applied the terminal:
This message is designed to prevent accidental erasure of the user description.
The user description will be preserved if this message is complied with.
Thus, turn off the power, reset the mode selector switch S4 and switch the terminal
on again. The terminal will continue to work with the current user description.
Note that the contents of the Flash memory will be erased if the power is not turned
off before the DIP switch S4 is reset.
