User lockout
You can select from three different levels of access at the local display to manage functionality through the
supervisory controller. This lockout is independent of any display or passcode settings. The existing temporary
occupancy capability is unaffected by this feature. User lockout hides the icons that are not operable. Table 6
describes the lockout levels.
Using the USB port
You can quickly and easily load firmware upgrades, back up the current settings, and restore settings to the
TEC3000 through the USB port with a USB drive. The TEC3000 can recognize eight configuration files or firmware
package files. The USB drive format must be FAT or FAT32. The drive cannot be NTFS format or USB 3.0. If you
upgrade the firmware or copy configuration files, you need the passcode if one is set up. Do not remove the USB
drive until the firmware upgrade is complete. The TEC3000 may restart and go offline to the NAE after a firmware
upgrade. The upgrade takes approximately three minutes.
Configurations are copied, except for the Communication mode. See Choosing the Communication mode
(TEC3612 and TEC3613 Models) to configure the networked devices.
Loading the firmware
1. Ensure that the TEC screen is on.
2. Insert the USB drive into the right side of the TEC.
See Figure 1 for the USB port location.
3. Press the Menu icon.
4. Scroll down the menu and press Update.
5. Press Load Firmware.
6. Select the correct firmware version. The correct file name has the .pkg extension.
7. Press Confirm if you have the correct firmware version.
The firmware is loaded from the USB drive into the TEC3000 operating system. The TEC3000 locates the new
firmware only if the new firmware is on the root drive of the USB drive. See Table 15 if the firmware is not
loaded correctly.
8. Remove the USB drive from the TEC3000 controller when the update is complete.
