Maximum transfer speed is dependent on the capabilities of transceiver at both ends of the signal and the signal integrity of the interconnecting cable. Implementors should verify the capabilities of the controller transceiver and test the signal integrity for excessive frame errors and reduce the transfer speed accordingly. |
OKE implementors should use these throughput estimates along with their product requirements to help determine the CWM communication port type (USB, serial, etc.) and settings (baud rate, full/half duplex, etc.) and the recommended CWM network type (WiFi, MiWi, etc.) for their application. Poor wireless connectivity or OKE file transfer throttling will reduce throughput so OKE implementors should verify that file transfers are meeting their requirements during the development and integration phase.
