Configuration - General Main Program Configuration Slave Program Configuration

General
Both the main and slave programs are configured via a configuration screen which enables the way the programs work to be changed to suit specific circumstances. The configuration files from versions prior to version 3.0 are not compatible with version 3.0 and above. When upgrading the installer copies the old configuration files to LANOffM.old (main program) and LANOffS.old (slave program) respectively. If you choose not to overwrite the configuration file when upgrading previous settings will be retained. If out of range parameters are chosen the changed data can not be saved. When the configuration screen is opened program operation is inhibited (apart from communications to and from the slaves) until it is closed when the program will be reset if any parameter changes have been saved. Saving configuration changes needs administrator privileges.

Port Allocation And Conflicts
The main program transmits on one port and receives on a separate port for each remote computer. This means Remote Computer 1 is received on the RX port set for the main program, Remote Computers 2, 3 and 4 are received on the RX port +1, +2 and +3 respectively. If a conflict occurs on one of the ports then then all ports are changed by altering the RX and TX Ports. The Slave on Remote Computer 1 Slave has the TX Port set to the same as the main program RX Port, Remote Computer 2 Slave has the TX Port set to the main program RX Port + 1, Remote Computer 3 Slave has the TX Port set to the main program RX Port + 2 and Remote Computer 4 Slave has the TX Port set to the main program RX Port + 3. The Slave RX Port is set to the same as the main program TX Port. If there are any port clashes one of the installations will give details. if you do change the port on one machine remember to change ports on all the computers using LANOff.
