The radio supports Ethernet operation on three IP payload ports. These settings are made on the
IP Payload Configuration (1, 2, or 3) Menu
In the Master unit only, Multihost may need to be enabled if more than one IP Payload port is
required. Multihost feature only pertains to Packet Radio Mode.
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. Addi-
tionally, Ethernet and OTA statistics can be monitored 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 transports the payload content of
Ethernet data to be sent over the air.
• This feature does not bridge Ethernet networks separated by radios. For more infor-
mation, see Ethernet Bridging found on Bridge Co in the Bridge Configuration section.
• A broadcast poll-response network is assumed, where addressing information is con-
tained in the payload portion of the UDP/TCP messages.
NOTE Screen selections vary depending on the mode selected. Three such screens are provided
for IP Payload 1, 2, and 3.
• — Enables or disables the IP Payload port.
