"Modify settings for operator panel (TCU)" dialog
The following dialog appears when "Modify settings" is selected from the main menu:
Figure 1-16
The central area is for setting the TCU parameters:
● "HT 8 individual mode" (yes/no)
This is only visible with HT 8, and is used to switch between Auto Mode and Individual
Mode.
There is no need to make any settings if an HT 8 is in Auto Mode, as the name is determined
automatically: ("DIP<n>") the MCP address and TCU index are determined by the DIP
setting ("DIP<n>").
It is possible, however, that another device is registered for the name selected. Such
situations may only prove to be temporary, as is the case when DIP settings or two HT 8
have been confused. For this reason, this status is not reported as an error immediately,
but identified as a possible problem instead ("potential name/DIP setting collision"). The
text will only read ("Name/DIP settings collision") if the situation remains unchanged after
some time has elapsed.
The process itself is unaffected, as the changes only relate to how the warning or error is
displayed. The explanatory text informs the user that they have probably assigned the same
DIP number twice and suggests they change one of them before rebooting the HT 8.
● "Operator panel index - TCU" (0-255)"
This specifies the TCU index. It matches the [Station] tcuIndex setting from the config.ini
file.
