CIDB Chassis Sensor
E326
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 v3.3 on the next bootup.
ACCESSORIES
Chassis Sensor
Using the ASUS CIDB
1. You must have an ASUS motherboard with a chassis connector. Motherboards
with intrusion components such as P2B-L(S), P2B-D(S), and P2B-D2 require
additional considerations (See reverse side.)
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.
3. To stop the alarm from sounding, use the LDCM v3.3 software or place a jumper
on (or short manually) the CLR jumper momentarily.
4. If you have an updated BIOS with intrusion support. Booting the computer
after an intrusion will require a password which is configured through BIOS.

ASUS CIDB Additional Considerations
1. All motherboards with CIDB: If there is no power to the motheboard (i.e. re-
moving the power cord or turning the power supply’s switch off) the alarm will
not sound but the CIDB will still memorize an intrusion event which BIOS and
LDCM will detect on the next bootup.
2. Motherboard with chassis intrusion components: Photo sensor, switch, and
memory will not operate with power removed. Power is required to send a
signal to the motherboard’s intrusion memory and buzzer. When using the CIDB
on these motherboards, all the CIDB functions will be disabled, the
motherboard’s intrusion components must still be used. The CIDB can benefit
these motherboards by providing a chassis switch which will operate even when
the power is removed. Pins [2-3] of the SW jumper can be used for a momen-
tary toggle switch and the CIDB’s battery will be used to send an intrusion
signal to the motherboard’s intrusion memory.
3. The P2B-LS motherboard must use an external battery pack on the EXTBATT
connector or else neither the alarm or intrusion memory functions will work.
