IP and Serial Control of Positioner
– All Models
Above communication ports may be used for control and settings of positioner and/or
payloads ports. Differential serial communication may be set to full or half duplex,
configurable in settings.
Communication to from base connector to payload ports is supported (see protocol
document).
“Transmit” and “Receive” are from the perspective of the positioner (DCE). Colors
shown for IP signals per EIA/TIA 568B are to aid or reference external wiring to the ports
and do not represent actual color of conductors inside the positioner.
