MEL Chassis Open Alarm Lead The ASUS CIDB Chassis Sensor 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 chas- sis intrusion by either light striking its photo sensor or by contact when its switch connectors are shorted by chassis-mounted momentary toggle switches.
III. HARDWARE SETUP 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.
Pins [2-3] of the SW jumper can be used for a momentary toggle switch and the CIDB’s battery will be used to send an intrusion signal to the motherboard’s intrusion memory. ASUS MEL User’s Manual...
