Tamper Protection - Bosch Access Modular Controller 2 Manual

Access Modular Controller 2
The extension package includes 2.2 kΩ resistors which can be used to replace R
resistors.
To detect the four states, the voltage drop in the connecting cable may not exceed special
values. The following table shows the maximum values of permissible cable resistance
depending on the used resistor combination.

Tamper protection

To protect the AMC2 against unauthorized access and so prevent tampering with sensitive
data, the AMC2 provides an additional interface to connect external tamper contacts. This
interface is a potential-free 2-pin pluggable screw connector marked with T. When not in use
this tamper contact should be shorted.
