KAM/BIT/102 Network Built-in Self Test module with event packetizer

The KAM/BIT/102 is a Continuous Built-In Test (CBIT) module which checks the Acra KAM-500 backplane and user-modules to verify correct system operation. The KAM/BIT/102 measures the precise value of the ±12V, ±7V and +5V power lines to ensure they are within specifications. Temperature sensors are located at the top block and the center of the module to allow the measurement of both the chassis top block and internal temperatures.

The KAM/BIT/102 checks the format and duration of each acquisition cycle and monitors correct operation by performing a checksum of all addresses transferred on the backplane.  

The KAM/BIT/102 module can be used to check both analog signal conditioning modules and bus monitor modules in a chassis. Channels on analog modules are checked to ensure that the signal stays within a set range. The KAM/BIT/102 can check the STATUS register from each bus monitor module to indicate when a user-defined error or event condition occurs. 

The KAM/BIT/102 generates and transmits event packets containing a user-defined text string and the parameter value that triggered the condition. The module is programmed by associating text strings with each configurable condition. When there is an ongoing triggered condition, a maximum of one event packet per second is transmitted for each configured event condition.
