UT-400/64 Firmware
Version 2.00 Release Notes
The difference between FW version 1.08 and 2.00 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.
“CNTRL + D” (Hold down the CONTROL key and press D). This enables the debug mode.
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.
The number 6 is then entered to enable or disable the function on this card.
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.
Status
Whenever this auto-reset function is performed by the software, a report is issued to the debug
port of the router. It takes the form of an ‘*’ followed by two numbers -- the hexadecimal
address of the card, and the number, 0 0 7, of the input that was reset.
