Selection & Expert Guidance

• Always verify if your cabinet uses the IS200EROCH1A (H1) or H2 group.
• Check the barcode serial number on your existing board ID device for revision matching.
• Ensure the +70V DC output to the ECTB is required for your specific contact configuration.
• Avoid connecting two keypads simultaneously to the faceplate and backplane ports.

Professional FAQ

• What is the function of the 9-pin Tool Connector on the IS200EROCH1A?
• It allows an external maintenance computer to interface directly with the IS200DSPX for tuning.
• How does the IS200EROCH1A handle redundant ground detection?
• In redundant configurations, the detector cable must connect only to the M2 rack EROC card.
• Does this board provide power to the terminal boards?
• Yes, the IS200EROCH1A supplies +70 V DC specifically to the IS200ECTB card.
• What happens if the green LED on the faceplate is not illuminated?
• This indicates a loss of logic power or a failure in the backplane connection to the IS200ERBP.
• Is the IS200EROCH1A compatible with third-party ground detectors?
• Yes, the ground detector connector supports both GE and certified third-party equipment.
