General information and networking
4.3 Networking
• "Electronic key system index - EKS" (0-255)"
This specifies the index of the associated EKS. It matches the [Station] eksIndex setting from
config.ini.
• "Enable direct keys" (yes/no)
This specifies whether direct keys (if present) should communicate with the PLC (yes) or be
treated as ordinary keys (no).
"OK" saves any modified values to the config.ini file or to the Flashstore (HT 8 individual
mode).
Parameters for the "config.ini" file
Two steps need to be performed:
1. Select "New" or "Replacement for existing panel".
2. Select what is to be replaced.
When an unknown TCU (i.e. not yet registered with the boot server) is started, a selection
menu containing both the "New" and "Replacement for existing panel" items will appear. The
accessibility of all the registered TCUs is tested in the background.
The status of this test process appears in the message line: "(0/3 panels inactive)".
Figure 4-13
If all the TCUs are active, the new one cannot be a replacement. The system will then
automatically switch to the name assignment phase after a set period of time has elapsed.
