The ASUS CIDB Chassis Intrusion Sensor Module

The optional ASUS CIDB is a module for providing audio alarm and logging when there is an intrusion into the chassis of a computer system. The module detects a chassis intrusion by either light striking its photo sensor or by contact when its switch connectors are shorted by chassis-mounted momentary toggle switches. An intrusion memory function allows detection by BIOS and LDCM on the next bootup.

Two switch connectors to detect intrusion by chassis mounted micro switches

Using the ASUS CIDB

1.You must have an ASUS motherboard with a chassis connector.

2.Connect the CIDB directly to the chassis connector or use the provided extension cable and mount the CIDB to the chassis using a double-sided foam adhesive tape.

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

3.Check the hardware settings:JP1 jumper should be enabled to use the photo sensor

MS1 and MS2 connectors should be connected to momentary toggle switches mounted on the chassis to use the contact method for triggering alarms.

SW jumper should be enabled to allow the hardware monitoring compo- nents to receive signals from the CIDB.

4.To stop the alarm from sounding, use the LDCM software or place a jumper on (or short manually) the CLR jumper momentarily.

5.If you have an updated BIOS with intrusion support, booting the computer after an intrusion will require a password which is configured through BIOS.
