How do I reset the screen resolution on the OTR 1001 to one supported by the monitor I’ve plugged in?
The OTR is usually able to set the correct screen resolution for the monitor that is being used. However with some VGA monitors, it may not be able to set the optimum display resolution automatically and instead it tries to use the screen resolution that was last set. In some cases, this may result in no display at all.
A program is available (zResolutionAdjust.exe) that first sets the display to a screen resolution of 1280 x 1024 (which all recent monitors support), then calls up the Intel Graphics and Media Control Panel to allow you to select the screen resolution you require. This program is available to download from this website.
The steps needed to set the screen resolution are given in our Help Note.
If a USB device (mouse, memory stick etc.) is plugged into the OTM1000 at the wrong angle, or if the device is not fully pushed into the USB socket, it is possible to "hang up" the USB interface, following which no devices are recognized. If this happens, it is necessary to:
- Remove the USB device.
- Power-down the OTM1000 system.
- Remove the power cord for a minimum of 30 seconds.
- Plug the power cord back in.
- Restart the system.
- Install the USB device, taking care to plug it in correctly.
In V2.3 of the OTM/OTR, the Audio Click pattern is generated by the sequence playing on Output 1. So if the OTM/OTR is being using in Dual Generator mode (using the GEN_2 software option) and the two generators are being used to generate independent sequences, the Audio Click pattern may potentially be incorrect for the sequence on Output 2. This is corrected in V2.4.
OmniTek LAB is a video monitoring tool and video signal generator, built into one product.
Very occasionally, and typically only when no display is connected either to the DVI or to the VGA port at start-up, the Intel chip set used in some versions of our 1RU XR, TQ, LAB and PQA systems can revert to its default flat-panel mode (which is not supported by the system hardware). Once this has happened, any monitor that is connected to the system will have a blank display (even after a hard reset) and overall, the system will appear faulty.
The system can however be recovered as follows:
- Switch the system on and allow time for the operating system to load.
- If the monitor is connected to the VGA port, press Ctrl + Alt + F1: this forces the system to switch on the VGA output. If the monitor is connected to the DVI port, press Ctrl + Alt + F4: this forces the system to switch on the DVI output. You should now see a display.
- Press Ctrl + Alt + F12. This displays the Graphics Driver Properties window.
- Use the 'Multiple Displays' page of this window to enable 'Clone Displays' and apply. The system should then return to normal use.

The DataLab was renamed the OTR 1003.
The AVDP card is available direct from OmniTek, from Nuhorizons and from TED in Japan. Click here for links.
Enabling loop-through involves making a range of settings in the AVDP registers. Detailed information about the registers is given in the AVDP Application user guide. The information shown below is for Release 188.8.131.52.
The two things you need to do are:
(i) Configure the SDI output (.the SDI inputs take care of themselves with the default values). (ii) Turn on the genlock so that the transmit clock matches the received clock.
The registers needed to configure the SDI output are:
Force frequency - VideoIO Capability/MGT resource control register (1) bit  - see application user guide page 42/43. Master Freq Select - VideoIO Capability/MGT resource control register (1) bits [3:2] - see application user guide page 42/43. SDIx Output Source - VideoIO Capability/MGT resource control register (1) bits [23:20] and [31:28] - see application user guide page 42/43.
The registers required to turn on the genlock are:
Genlock Source - Spartan3 Capability/Genlock Control Register bits [1:0] - see application user guide page 49/50 Genlock Control - Virtex5 Capability/Virtex5 Control Register bits [19:16] - see application user guide page 33
