Trouble Shooting Guide (Frequently Asked Questions)

This section is to be a help in solving some common difficulties. If there is no control from the front panel
first check that the Rem/Local switch is set to Local.
Q: My V64xx powers-up with a static test pattern or black output, although a valid SDI video signal
is connected to one of its inputs.
A: 1. Check whether the Front Panel HD/SD LED is lit. This indicates that a signal is being received.
2. Check whether the Input selection is set correctly.
3. Check that the Test Pattern Generator is turned off.
4. Make sure that the mode of operation (SD/HD) matches with your Input Standard.
Set to 'Auto' sensing if in doubt.
Q: My V64xx does not synchronise to the external reference.
1. Check whether the Front Panel Ref. LED is lit. This indicates the presence of an ext. reference.
A:
2. Check whether the ext. reference input is selected.
Q: It seems that embedded Audio data does not get passed through the Frame Synchroniser (in
fact, no Ancillary data whatsoever).
A: Check whether the Anc Data enable control is set properly.
Q: I want to add a number of frames extra delay to the output, but I cannot find the associated menu item.
A: You need a V6402 (or a V6404/06/08/18SY) with the Field/Frame-Delay (FD) option enabled. This is a
factory installed option and requires a password in order to enable it. If the option is enabled, you will
find the corresponding control menu under VIDEO : F Delay.
Q: The output generated by my V6406/08/18 looks corrupt.
A: Make sure that the selected Output Standard has the same frame-rate as the Input signal.
Q: I want to use my V6402 as a stand-alone Test Pattern Generator, but I cannot see anything on
the Monitor.
A: 1. Make sure that the selected 'Default Standard' is compatible with your Monitor specification
(CONFIG : Def Std). Note that some Broadcast Monitors cannot cope with progressively
scanned modes with frame-rates less than 50Hz.
2. Check whether the TPG is turned on an that you have not deliberately selected a 'Black' test
pattern (ENG'ING : TestPtn : Bars 100, Bars 75, etc.)
