Installation Prerequisites
Ensure there is a provision for a ground circuit. The Card Access System assembly must be grounded by a qualified
electrician. An improperly grounded unit can result in equipment malfunction and void the warranty.
Use the latest Card Access System controller firmware. Mircom periodically updates panel firmware and Configurator
Software to add features and correct any minor inconsistencies. For information about the latest firmware or software
visit the ‘Manuals and Downloads’ section of the Mircom website at www.mircom.com.
Before Starting the Configuration
Configure the system using the Configurator software using a USB or modem connection. Verify the following:
Ensure that the controller and all connected devices and components are fully operational.
Ensure the controller DIP Switches are set with a unique RS-485 network address.
Ensure the Configurator software is set with the correct controller RS-485 network address.
Ensure that your PC is set with the correct date and time.
