TZL400 units converts a video signal into a high resolution RGBHV signal.

It can be used for videoprojection or onto TFT visualizer to improve picture quality.

The wide choice among 11 input signals, each with the combined audio, makes the TZL400 very useful in the presentation domain, where many sources, either video or graphics, must be displayed onto a single destination.

TZL400 features the “through blank” switching where the switching time is user-adjustable to permit the perfect matching with the destination device.

Two microphones (one is line level type) can be connected to the TZL400 and then mixed with or replacing the outgoing audio.

TZL400 provides 8 dry contacts for room control function.

TZL400 manages two IR receivers, two IR transmitters and 5 common outputs to control either itself and some other remote appliances (tipically DVD players, SAT receivers etc.).

Software to upload firmware into Elpro units


Firmware updating of the Elpro devices is possible using the specific utility UPLOADER.

This software should be downloaded and installed on a PC in a Windows environment.

To perform the updating of the firmware it is necessary to connect the device to the PC serial line and therefore to perform the action (typical for every device) to put the device in UPGRADE MODE.

Then load the .hex file of the new firmware version and start uploading to the device.

At the conclusion of the updating it is necessary to turn OFF and ON again the device.

How to set the TZL400

Turn the device ON holding the key PC4 pressed.

The UPGRADE MODE is signaled with the led Resolution 480p and 576p lighted.

Notes: Immediate execution of SEQUENCE command and bugs removing.

Current release: 1.5
