3.5 General Setup

The general setup page provides some general installation settings (section 'General') and the settings of the DEICE-Controller's SNMP agent (section 'SNMP Configuration'). The settings are in particular:

General

• Display Title --- By default the state page of the web interface is titled 'State'. You may change this title, e.g. to a station name or location. The display title also is replied to SNMP requests for the MIB-II 'sysName' parameter.
• Date & Time --- Click to 'Set Time' in order to set the actual date / time at the DEICE-Controller's real time clock. Enter the actual date / time in exactly the format YYYY-MM-DD HH:MM:SS .
• State Page Refresh Rate --- The state page by default refreshes automatically every second. The refresh rate may be slowed down, setting it to zero disables the automatic refresh completely.
• Serial I/O Address --- The serial interface may be operated either with the MOD-95 / Miteq protocol, using a device address 'A' to 'G' or with a simple ASCII / terminal protocol (setting 'NONE'). See chapter 4.3 The RS232 remote control interface for details.
• User Password --- Defines the user password (default 'user'), which is required to actuate switches or to set output circuits of the DEICE-Controller. An empty password disables the password prompting.
• Administrator Password --- Defines the administrator password (default 'admin'), which is required to change any configuration settings. An empty password disables the password prompting.

SNMP Configuration

• Read Community --- Sets the SNMP community string expected for read access. The default is 'public'.
• Write Community --- Sets the SNMP community string expected for write access. The default is 'private'.
• Trap Community --- Sets the SNMP community string sent with traps. The default is 'trap'.
• Trap Destination IP 1 --- Enter the trap destination IP address (dotted quad notation) to make the DEICE-Controller sending traps by UDP to this host. Setting the parameter to 0.0.0.0 disables the trap generation.
• Trap Destination IP 2 --- Enter the trap destination IP address (dotted quad notation) to make the DEICE-Controller sending traps by UDP to this host. Setting the parameter to 0.0.0.0 disables the trap generation.
• Trap Destination IP 3 --- Enter the trap destination IP address (dotted quad notation) to make the DEICE-Controller sending traps by UDP to this host. Setting the parameter to 0.0.0.0 disables the trap generation.
• Trap Destination IP 4 --- Enter the trap destination IP address (dotted quad notation) to make the DEICE-Controller sending traps by UDP to this host. Setting the parameter to 0.0.0.0 disables the trap generation.
• System Location --- The DEICE-Controller replies to MIB-II sysLocation requests with the text entered at this place.
• System Contact --- The DEICE-Controller replies to MIB-II sysContact requests with the text entered at this place.

Real Time Clock battery backup

The DEICE-Controller's real time clock is backed up by a goldcap capacitor. The goldcap supplies the RTC chip with power for several days if the main power is missing. This is the preferred mode of RTC backup for stationary installations of the DEICE-Controller.

For applications where the DEICE-Controller is powered up only occasionally, a lithium cell may be connected inside the DEICE-Controller housing in order to provide a permanent buffering of the clock.
