Is client-to-client communication possible with RM024-S10 radios?

Yes, it is possible for RM024 client radios on the same network to communicate with each other. The RM024 is a Server-Client architecture, so there must me one radio configured as a Server and in-range for the network to operate. However, the clients can be configured to communicate with each other in the network. To configure this scenario there are two options, depending on your desired application. Server:    Auto Config Broadcast Mode Enabled System ID & RF Channel must match on Clients configured for the same network Clients:   Auto Config  Broadcast Mode Enabled , (No Auto Destination/Auto Destination Beacons) Same System ID and RF Channel as Server (This would enable the Clients to communicated with each other and the Server - Data will be sent to all radios on same network.) *****OR***** Server:     Auto Config Broadcast Mode Enabled System ID & RF Channel must match on Clients for same network Clients: Auto Config  Addressed to each other by setting Destination Address to the Destination radio's MAC Address Broadcast Mode  Disabled, (No Auto Destination/Auto Destination Beacons)  Same System ID and RF Channel as Server (With this configuration the clients will only communicate with the radio they are addressed to.)
