They’re built to different standards. AMREL’s ROCKY computers meet military standards for ruggedness, whereas our medical computers meet IEC 60601-1 standard for medical electrical equipment.
This has led to some hardware differences. ROCKY’s military computers are shielded to meet MIL-STD 461E for electromagnetic interference. To meet EMC (as well as safety) requirements, the medical versions have rubber pads on the bottom and fewer interface connections at its rear.
Note: Both AMREL’s ROCKY and medical computers are certified by third parties. Unlike other companies, we are not satisfied with unsubstantiated claims of compliance.
