54 • DashBoard Menus SRG-2200 User Guide (v6.0)
 Option Update Keys are in the form of a 12-character string. Each key is completely unique to a specified option
in a particular SRG-2200. Keys will not work for other options on the same SRG-2200, nor on any other
SRG-2200. Remember to store these keys in a safe place - you may need to re-enter them if a system error
necessitates a system re-configuration.
Encryption Key
Every time the SRG-2200 is powered on, this entry displays a pseudo-randomly generated 13-character key. This
menu item cannot be changed by the user. This key is unique to each SRG-2200 and should be quoted when
requesting any additional Option Enable Keys.
NTP
These menu lines will contain non-zero entries. These will be factory default values, and will be confirmed by the
“:” between the character groups. For valid keys, the character groups will be separated by “-”.
Calibration Tab

The Calibration tab contains fundamental settings relating to the functionality and accuracy of the SRG-2200.
These settings are programmed during initial testing, configuration and alignment. Under normal circumstances,
it should not be necessary to adjust any of these settings after the unit has been installed. It is a good idea to make
a manual record of these settings in case they become corrupted or are inadvertently changed. A convenient way
to achieve this is to print this page, record the stored values alongside the respective menu lines, then store the
list in a safe place.
Enable Calibration Changes
This feature enables the user to change any of the calibration settings in the remainder of this menu.This menu
option is always unselected (box is cleared) upon entry - it requires a conscious action on the part of the user to
select the box and thereby enable calibration value adjustments. The options are:
• Cleared — Calibration is disabled (Default). The user may view the menu values at any time.
• Selected — Calibration is enabled. The user is able to change any of the preset values.
Oven Frequency
This field allows the user to adjust the frequency of the internal 10MHz oscillator. When the SRG-2200 is
configured for Internal Lock (refer to the section “ Genlock Tab ” on page 34), the video outputs on the SRG-2200
will “free run” compared to an external video signal from a known reference.
To set the 10MHz oscillator
1. View both the Composite output and the known reference on a vector scope.
2. On the vector scope, ensure that the known reference is also looped through to the EXT REF input, and that the
EXT REF function is enabled.
3. Adjust the Oven Frequency menu setting so that the Composite video output signal rotates at less than 1
cycle/second compared to the known reference.
This setting varies from unit to unit.
Disclaimer
Most of these settings are determined during initial testing, configuration and alignment. They should not normally
require adjustment or re-configuration during service. In some cases, specific test equipment or even custom
apparatus is required to perform calibration and configuration.
On no account should the user attempt to alter any of these settings without proper authorization from Ross Video.
If problems are encountered, these settings can be re-instated. Contact Ross Video for further instructions.
