As RCI is designed to be used by a program it is useful when creating a custom configuration user interface or if you want to create utilities to configure or initialize devices through external programs or scripts Disadvantages Using RCI as a device configuration interface presents these disadvantages Digi Connect Family User s Guide Introduction RCI uses HTTP as the underlying transport protocol Depending on the network configuration use of HTTP as a transport protocol could be blocked by some firewalls RCTis quite complex to use requiring users to phrase configuration requests in Extensible Markup Language XML format It is a power user option intended more for users developing their own user interfaces or for users implementing embedded control and thus potentially using RCI over serial than for end users with limited knowledge of device programming Notall actions taken through the default web interface have direct equivalents in RCI Therefore it may not be easy for some end users to determine what needs to be sent via XML for a particular style of request Accessing the Remote Command Interface RCI access consists of program calls Where to find more information See the Digi Connect Integration Kit for more details on RCI Simple Network Management Protocol SNMP Simple Network Management Protocol SNMP is a protocol for managing and monitoring network devices The SNMP architecture enable
