4.17 Remote Mode
Remote mode permits a User to select from multiple remote control permissions, or isolate remote control to a single
control selection:
• Multi Control mode (default): There are three modes of remote control for the MX actuator allowed when the remote
mode is configured for multi-control: digital control, analog control, and network control. Digital and network control
operation is based on the last command received. Analog control operation in initiated by either toggling user input 2
(configured for CSE input) or breaking and reapplying the analog signal.
• Digital Control Only: the unit will operate only upon the last digital input command received.
• Network Control Only: the unit will operate only upon the last network command received.
• Analog Control only: the unit will operate only upon the last analog input command received.
