Entries are established or changed at the Network Management Console, a terminal attached to the maintenance port, or remotely through the 10Base-T Ethernet port. Example: 1.
MM102365V1 Rev. B 9.5 MANAGING THE FREQUENCY LIST TABLE The ISM radio uses the Frequency List Table to establish a communication link with other radios in the ISM network. Each entry in the table corresponds to an allowed frequency to be used for linking with other radios. Allowed frequencies will fall within the range from 2412-2468 MHz.
MM102365V1 Rev. B 9.5.3 Displaying a Frequency List Table The ISM radio uses the Frequency List Table to establish communication link with other radios in the ISM network. Only frequencies listed in the table are available for linking to other ISM devices. To display the frequency list table, use the command below. Example: 1. Type the Display Frequency List command at the terminal attached to the maintenance port: at*fldisp . 2.
MM102365V1 Rev. B 9.6 SAVING CONFIGURATION AND PARAMETER CHANGES This manual makes repeated reference to the importance of saving configuration changes to non-volatile memory to make your changes permanent. The ISM Radio uses both volatile (temporary) and non-volatile (permanent) memory to handle configuration details. At Power Up, configuration data is copied into non-volatile memory. 9.6.
MM102365V1 Rev. B 9.6.2.2 Permanent Parameter Changes When making changes to radio parameters you wish to make permanent, take the extra step of saving them to non-volatile memory so you will not lose the changes when the radio is powered down. To save the changes, type: at&w then press the Enter key. Changes can be saved at the network management console, a terminal attached to the maintenance port, or remotely through the 10Base-T Ethernet port. Example: To save radio parameters: 1.

MM102365V1 Rev. B 5. Are there other of our ISM links in the area? If so, the configurations of these links should be checked. ISM links that can potentially see each other should have unique device addresses. With unique address the links can co-exist even if on the same frequency. If the links do not have unique address the signal strength must be approximately 15 dB better at the capturing receiver. 6.
MM102365V1 Rev. B 18. Measure RX signal strength and compare it to the expected design signal strength. The measured and designed to signal strength should be within a couple of dB, if not, you have some sort of RF issue. If the antenna system checks out, the difference could be due to an obstruction in the path.4 Repeat this test on each port to verify the ports on both ends (if so equipped) and to test out each RF path. 19. Interference avoidance.
