Selection Recommendations
Choose IS200KSPAH1B for local keypad operator interface and serial port connectivity with highway communication. Select the “B” revision for improved reliability. Verify compatibility with your keypad and serial devices.
Precautions and Important Notes
Use ESD-safe handling. Verify field wiring and keypad/serial connections. Confirm compatibility with your specific keypad and serial devices. Never interrupt firmware updates. Board draws 2.0A – verify rack power capacity. Document all configurations. Store spares in anti-static packaging. Do not mix IS200KSPAH1B with “A” revision boards in redundant pairs without verifying identical firmware. Allow 30 seconds boot time. Test all keypad, serial, and highway functions during commissioning. The IS200KSPAH1B is critical for local operator interface – ensure all settings are verified before placing in service. Ensure serial cabling does not exceed maximum recommended length. Regular verification of keypad and serial communication is recommended. The improved “B” hardware may require updated firmware in other system components for optimal compatibility.
