Uploading Bootloader
Typically, do not upload the Bootloader unless advised to by Technical Support (or the ftp site).
Note: Do not attempt to upload firmware across a wifi connection.
Technical Support recommends connecting the DeviceMaster UP directly to a PC or laptop when
uploading Bootloader. You may also want to connect the DeviceMaster UP to a UPS while
uploading Bootloader to avoid any power interruption. A power interruption while loading
Bootloader will require that you send the DeviceMaster UP back to Comtrol for repair.
Note: Only upload Bootloader to one DeviceMaster UP at a time.
1. Make sure that you have downloaded the latest version .
2. Right-click the DeviceMaster UP in the Device List pane for which you want to update,
click Advanced and then Upload Firmware.
