Firmware upgrading allows a user to overwrite the internal firmware of the datalogger with a newer updated version of the firmware Firmware upgrading can be done by using USB connection Wireless via GPRS Via Comport 5 9 1 When to use Firmware upgrades Normally a user never uses this feature as long as he is satisfied with the performance of the system In time however the need for additional features may arise For example a new serial sensor is introduced on the market and a customer wants to connect this sensor to the ML 2012 When YDOC has extended the firmware to support that sensor a new version of the firmware is released After the user has performed the firmware upgrade his old ML 2012 now supports the new sensor Normally when the system is running fine and no additional requests exists we recommend NOT to perform a firmware upgrade 5 9 2 Firmware upgrade procedure How to perform a firmware upgrade First download the latest version of the firmware from your YDOC Dealer Use the menu and select the option Maintenance Follow instructions from the menu Use Y Modem protocol to send the new firmware to the datalogger When these steps are completed the new firmware is active We recommend the use of the USB connection over the wireless function This is because of possible drop outs in communication When a firmware upgrade procedure is interrupted the upgrade will fail but the u
