IP Payload is intended to be used in a poll-response system. An Ethernet
device at the Master radio sends UDP/TCP poll messages to the
Master's Ethernet port which is configured to listen for data. The poll is
sent OTA and a RTU/PLC attached to one of the Remote radios (via
serial or Ethernet) responds. The response is sent OTA back to the
Master radio. The Master radio then sends the response back to the
polling station via Ethernet.
When configuring this feature, you are notified of the success or failure
of the operation. Additionally, Ethernet and OTA statistics can be mon-
itored to inspect the success of the poll-response communication.
The following additional points apply to Ethernet payload operation:
• To make efficient use of limited bandwidth, this feature trans-
ports the payload content of Ethernet data to be sent over the air.
• This feature does not bridge Ethernet networks separated by
radios. For more information, see Ethernet Bridging found on
Page 55 in the Bridge Configuration section.
• A broadcast poll-response network is assumed, where addressing
information is contained in the payload portion of the UDP/TCP
messages.
NOTE: Screen selections vary depending on the mode selected. Three
such screens are provided for Payload 1, 2, and 3.
