Auto-switching function The auto-switching mode follows the listed principles: New input principle Once it detects a new input signal, the TEK 51T-HD switches to this new signal automatically. Power rebooting principle TEK 51T-HD offers this feature to remember the last displayed signal when rebooting. While rebooting, the TEK 51T-HD automatically enters into auto-switching mode and detects all inputs to memorize their connection status. If the signal last displayed is still available, then it will choose the signal to output. If not, there will be no signal on its outputs. Signal removing principle Once it has removed the current display signal, the TEK 51T-HD will detect all input signals with priority from INPUT 1 to INPUT 5. It will select the first detected signal to its output. Notice: The Auto-switching function works only when an input detects a new signal, loss of a signal, or power rebooting. With any VGA port set to AV or YPbPr the system is not able to enter in Auto-switching mode. 10

4.1.3 Operation Examples: Connect INPUT 2, INPUT 4, and INPUT 5 ports to their source devices and select INPUT 4. Press and hold the front key SOURCE/AUTO for 7 seconds or more to enter into auto-switching mode. No change on inputs and the output remains on INPUT 4. Connect INPUT 3 with a source device and the output switches to INPUT 3. Remove the signal from INPUT 3 and the TEK 51T-HD will search for input signals on inputs 1 through 5. When it detects INPUT has video, it will choose INPUT 2 to output. Cycle power on the TEK 51T-HD and it will select INPUT 2 to output. 4.1.4 Firmware Updating Firmware updating will update the firmware of this scaler-switcher. The TEK 51T-HD supports firmware updating via USB flash drive. Use the following to update: 1) Copy the file MERGE_51T-HD.bin to the root directory of a USB flash drive.

7. Troubleshooting & Maintenance 1) When the output image is looks like noise or snowflakes, common problems include but are not limited to: Poor quality cable. Please try another higher quality cable. The video cables are loose. Try reconnecting them. 2) When it is not able to manage EDID, the HDMI cable may be broken or loose. 3) When a user cannot control the switcher by computer through its COM port, check the COM port number in the software and make sure the COM port is in good condition. 4) If the POWER indicator doesn t work or respond to any operation, ensure the power cord s connection is secure. 5) No output image when switching: Use an oscilloscope or multi-meter to determine if there is a signal at the input and output end. If there is no signal, the connection cord may be broken or have loose connections. Use a new cable and/or attempt to reconnect them. If none of these methods have worked, there may be something wrong with the switcher. Contact your dealer if this is the case. 6) If the static becomes stronger when connecting the video/audio connectors, the grounding may be incorrect. If it is incorrect, the connection may damage the switcher. 7) If it is not able to control the scaler-switcher from front panel buttons, but able through RS232 commands, the front panel buttons are probably locked. Send command 50605% to unlock. 8) If the scaler-switcher cannot be controlled by the buttons on the front panel, RS232 port, or IR remote, the switcher may be broken. Send it to the dealer for repairs. 210.348.6565 34
