Firmware-Update of the Serial-Modem 7XV5655 ============================================ NOTE: It is essential to install the new Config Tool V15 prior to the firmware update. The firmware update to version 14.7 also makes the application of the serial modems in Virtual LAN networks possible (VLAN). The register S30 (Inactiv counter) may now be set in the range from 1-255 seconds. The setting 0 (default) deactivates this function (refer to manual 7XV5655). Load the firmware V14.7 into the serial modem. - Decompress the Firmware-Update to C:\Siemens\7XV5655\Firmware\Siemens_Serial_Modem_14-7.hex. - Connect (only one) the serial hub to the operator PC by means of a cross-over patch cable. - Open the config tool with the right mouse button and select "Update Firmware". - Search for and select the hex-file and start the upload. All settings (apart from the password protection, the name and the IP-Address) are reset and must be reapplied. Whether the firmware update and application of settings is possible over the network, dependson the network configuration and the loading of the network. To be on the safe side, the update should be done via a point to point connection. All the best.
