7.2ASUS CIDB Intrusion Detection Module

The optional ASUS CIDB is a module for providing audible intrusion alarm and logging for ASUS motherboards equipped with the chassis connector. The module detects a chassis intrusion by either light striking its photo sensor or by the closing or opening of a chassis-mounted momentary toggle switch. An intrusion memory function allows detection and clearing the intrusion notification by the BIOS program on the next bootup.

7.2.1 Using the ASUS CIDB

1.You must have an ASUS motherboard with: (1) a chassis connector and (2) a System Management Bus (SMB) connector.

2.Connect the CIDB directly to the chassis connector or use the provided exten- sion cable and mount the CIDB to the chassis using a double-sided foam adhe- sive tape or with screws and spacer posts.

CAUTION! The CIDB’s component pins and metallic points must not come in contact with another metallic surface or else shorting will occur!

3.Use the SMBIN connector and the provided SMB cable to connect the CIDB to the SMB connector on the motherboard. If another SMB device is already used on the motherboard, you may unplug it and connect it to the SMBOUT connec- tor on the CIDB.

4.Check the hardware settings:

•PHOTO jumper should be enabled to use the photo sensor.

•MS1 and/or MS2 connectors should be connected to momentary toggle switches mounted on the chassis to use the switch close or switch open method for triggering an intrusion event.
