Utah-400 Firmware
Version 2.09 Release Notes
2.09 is an enhancement to the 2.08 version. Some disturbances, specifically from Panasinic
MII machines, were of such short duration that the polling method of determining that a source
had unlocked and then re-locked was not adequate. A ‘change since last read’ register in the
TVP5145 was utilized to determine when this had happened and reset the input channel, if so
configured. All menu items are the same as 2.08.
Version 2.08 Release Notes
The difference tetween FW version 2.08 and 2.07 solely deals with the 121045-1 Analog to
Digital Conversion cards.
A function and associated menu items was added that allows a selectable reset of the con-
verter chips on these cards when the transition from an unlocked state to a locked state. This
was put in place due to an issue with the ADC chips that prevented them from successfully
locking to a source after having been fed non-standard video for a period of time. This typically
manifests itself on inputs fed by satellite or microwave receivers that transition from a de-tuned
mode (where unwanted video is put out) to a tuned mode where real video is generated.
Menu Items
To enable this feature on a given block of 8 inputs, a series of commands must be entered.
1.
“CNTRL + D” (Hold down the CONTROL key and press D). This enables the debug
mode.
2.
Use upper case U and D keys to direct the software to the card you wish to enable this
function on. After each entry, the card that the software is ‘pointed’ to is reported.
3.
The number 6 is then entered to enable or disable the function on this card.
a. When the ‘6’ key is pressed, the system will report a string of bits that represent
whether or not the function is enabled for each card slot. This data takes the form
of 40 bits, represented in 5 bytes of hex data. A 1 in a bit position indicates that the
function is enabled for that card.
