Introduction
METSmanager uses radio modems to communicate with machinery. The radios communicate via one of two communication protocols: KEA and IP. KEA and IP radios do not communicate with each other.The radio infrastructure at a site could possibly contain radio networks of each type. Generally, the network is a single type of radio. The METSmanager software is designed to support only a single type of network. The software does not support both types at the same time. Select the correct communications protocol when the METSmanager software is installed. Each network has specific information for the network.IP Wireless Network
The IP Wireless Network uses the Microsoft Windows IP protocol to communicate with machinery. FTP and UDP can be used in order to communicate with the machines. ReferenceRefer to Systems Operation, "Site Properties" in the "Transfer Method" section for additional information about FTP and UDP.Communication is via a wireless network of IP radio modems. All IP communications with respect to bandwidth are determined by the IP protocol. Communications over the network can be affected by any other application that is being used on the network. There may also be environmental conditions that could affect the communication.

The KEA Wireless Network uses the proprietary KEA protocol to communicate with machinery. Communication is via a wireless network of Trimble KEA radio modems.. METSmanager may have data for a machine. A portion of this file is sent to the machine. The system receives some of the data from the machine. The system then communicates with the next machine. Each machine is polled one at a time until all machines have been polled.Outgoing files are placed in a queue according to priority and to the machine that will receive the data. All High priority transfers occur before Normal priority transfers. Normal priority transfers occur before Low priority transfers. Transfers of the same priority are placed in the queue in order to be distributed equally to all machines.Note: . When all of the files are sent at High priority, the speed of the communication does not increase. The files will only be delivered before any Normal priority files are transferred.Data can be lost over a radio network because of environmental conditions. The radios and the application are designed to overcome these problems. This ensures that all data is transferred correctly. If communications to a machine temporarily fail, an "Out of Radio Contact" status is shown in the "Machine" window of METSmanager. The Machine window must be set to display "Details" to show this status.METScomms will still attempt to communicate to the machine that is failing. Communications will not be as frequent as normal communications. Normal communications will resume when contact with the radio is established again.For more information, use "Find" to search for "Operation of Wireless Network" in the METSmanager Help Topics."Packet Rate" Setting
The "Packet Rate" setting controls the number of packets that are sent to the radio from
