ELECTRICAL-KEYBOARD Input/Output: Data Logic Levels – Standard TTL Input Voltage: 4.75 to 5.24 VDC Input Current: 250 mA (maximum) ENVIRONMENTAL Temperature Operating: +32°F to +131°F (0°C to +55°C) Storage: -40°F to +149°F (-40°C to +65°C) Electromagnetic Compatibility The keyboard is designed and manufactured to comply with Class B limits, Part 15 of FCC rules for computing device peripherals. Electrostatic Discharge (ESD) The level of ESD protection is dependent on the grounding of the host system. In most cases the RT keyboard features 15 KV protection without catastrophic failure and 10 KV protection without any soft errors. Conforms to IEC 801-2 specifications. Compatibility Certifications Microsoft and Sound Blaster Compatibility Labs and Novell NetWaare Approval. Agency Approval Keyboard is approved by FCC class B, UL, CSA, TUV, CE and VDE. Buffering The keyboard will buffer up to 16 bytes when the system is unable to receive scan codes from the keyboard. The keystrokes are stored in a first-in-first-out (FIFO) buffer. Input-Output Data Logic Level Data input and output is standard TTL level. ELECTRICAL Input Voltage 4.75 to 5.25 VDC. Input Current 250 milliamperes maximum.
