Special Features

Integrated MTBF Counter
One-time write Flash area for number of MTBF hour before shipment. Timer count up by “hour". Built-in TTL alert signal will be enabled after time counter over MTBF number
Fault tolerance – Redundancy
Two CPU boards may be run in parallel—connected to the same ISA bus and executing the same software. Each board will be designated Master or Slave during power on. The system detects six different fail conditions and responds accordingly. I/O can also be switched between boards during each fail over. Contains a built int System Fail Counter.
ISOinChip
32 Byte one-time write Flash area containing all service tracking data. Data includes: Date codes of all major components, Model and Serial numbers, Unique serial code of SoC, Distributor code, Ship date, etc.
