Third-Party Control Systems
Miranda provides assistance to users wanting to configure Miranda products to function with third-
party control systems. However, because Miranda does not manufacture or warrant control systems
from other vendors, we cannot guarantee overall performance or answer all possible configuration-
related questions. For assistance, contact the manufacturer of the control system in use.
In many cases, router features and functionality are limited when using a third-party control sys-
tem. For example, the third-party system may not optimally manage mono routing, while the
NV9000 control system easily manages this function.
Please consult with Miranda if you are considering using a third-party interface to control an
NV8256-Plus router. For contact information, see

Setting Redundant Crosspoint Card Switching
The NV8256-Plus crosspoint card features four buttons located on the front of the card. When the
card is installed in the
middle crosspoint card slot —the slot for the optional, redundant crosspoint
card—the buttons become active and can be used to change which signals the crosspoint card man-
ages. (See Figure 4-1 on page 53.)
By pressing a button on the front of the crosspoint card, the card can be directed to take over active
control of signal switching from another crosspoint card, become a standby crosspoint, or enable
external control. By setting the redundant crosspoint card to take over active control of the primary
card’s signals, a primary crosspoint card can be removed without experiencing any downtime.
The brightness level of the buttons indicate the current status: full-brightness indicates that the
remote and local control is active; half-brightness indicates local control only is active.
