Prerequisites
Please observe the following important prerequisites:
• Equipment and software properly installed.
• NV9000 requirements met.
• All control panels properly configured.
Overview
The NV5256 is a machine control router —a successor to the NV3256. A machine control router
transmits control messages and responses between devices such as VTRs and edit stations.
Physically, the NV5256 has an 8RU frame that holds the following items:
• 16 I/O cards (RS-422/485 or RS-232)
• 16 RJ-45 backplanes.
• 2 expansion cards (for redundancy).
• 2 control cards (for redundancy).
• 2 power supplies (for redundancy).
A single NV5256 frame provides a 256×256 routing matrix. Two NV5256 frames can be connected
in tandem, using expansion cables, to provide a 512×512 matrix. A frame need not be fully popu-
lated. The NV5256 can be as minimal as a 16×16 router.
The following figures show the NV5256 features.

NV5256 Machine Control Router • User’s Guide 5
2. Introduction
Overview
I/O Signals
I/O signals are serial (either RS-422 or RS-232) at up to 115.2 kBaud. Signals are bidirectional:
commands in one direction; responses in the other.
A port can be considered a “controlled” port or a “controlling” port.
A destination can also be the controlling device:
For example, a recording VTR sends signals from an edit list to various source machines in an edit
suite.
In most, if not all, cases a controlling device must communicate with a controlled device and not
another controlling device. (The reason is that a transmitter must connect to a receiver.)
SThe Tx-to-Rx connection, of course, depends on the cable. Straight-through cables are consid-
ered preferable.
Router Configuration
The NV5256 router has several configurable options. It supports several signal options that can be
configured for each port.
The router can be (and must be) configured to operate according to your system constraints. You
will need to specify the size of the router matrix, the type of ports, communication parameters, and
so on.
Your router control system must also be configured. In an NV9000 router control system, you will
specify source and destination device names, router names, levels, level sets, and so on.
The NV5256 itself must be initialized through UniConfig.
Router Control
The NV5256 can be controlled by an NV9000 Router Control System. An NV9000 system controls
one or more routers of different types. Central to the system are the NV9000 servers. The NV9000
can include one or more control panels with which operators may perform routes through the
NV5256 and through other routers.
Alternatively, you can use a compatible third-party control system such as the SMS7000.
SUsing an SMS7000 control system requires specially configured router control cards.

2. Introduction
Overview
The NV5256 has these control connections:
• Ethernet, from an NV9000 router/panel network (through a switch), to primary and redundant
control cards.
• Serial control from primary server and secondary server to primary and secondary control cards
(4 connections).
• Video reference (4 connections). Loop-through for main and redundant reference signal.
• AES reference. Two BNC and two STP connectors for each control card.
• “Node Bus” interface for SMS7000.
• System alarm outputs and power supply alarm outputs
Router Expansion
Two NV5256 frames can be connected to create an expanded router. Six expansion ports are at the
top right at the rear of the router. There are 6 BNC connections —3 coming in and 3 going out.
Router Options
Breakout Panel
A 64-port breakout panel is available that has RJ-45 connectors on one side and DE9 (female) con-
nectors on the other. This panel can make it easier to use DE9 connectors if you prefer them.
The breakout panel is RS-422 only
SOlder versions of the breakout panel might not function correctly.

NV5256 Machine Control Router • User’s Guide 7
2. Introduction
Functions
SMS7000
If you are using an SMS7000 router control system, you will require an SMS7000 mezzanine card
installed on all router control cards.
Functions
The NV5256 router can be configured with partitions of 4 types. Each partition is considered a
physical level. The physical levels can be of 4 “signal types.” The signal types accommodate the
different characteristics of Miranda’s NVISION series routers and third-party routers.
Any of the router’s ports can be specified as one of 7 different types, generally configuring the port
as a controlling port, a controlled port, or a port whose type can be changed dynamically.
The port types accommodate (1) the different devices you might have in use and (2) the connection
requirements that differ between RS-422 and RS-232 ports.
The signal types and port types are specifiable as parameters in UniConfig. Those parameters, how-
ever, affect the behavior and operating characteristics of the router, which are discussed briefly
here.
See Chapter 4, Configuration on page 27 for more information.
Signal Types
Four “signal types” are available:
NV5256 physical levels in NV9000 router control systems always are “machine control forward.”
Third-party control systems are “machine control reverse.”
A controlling device sends commands to a controlled device. The controlled device passes
responses (such as status) back to the controlling device. A source device can be a controlling
device or a controlled device. A destination device can be a controlling device or a controlled
device.
When you are configuring some NV9000 control panels, you can create a “source is master” button
that toggles whether the source or the destination is the master (i.e., controlling device).
Some control panels have a broadcast button that allows one source to control multiple destination
devices. (“Source is master” is a requirement for machine control broadcast.)
Machine Control Forward
“Machine control forward” means that the source device is the controlling device.
Machine Control Reverse
“Machine control reverse” means that the destination device is the controlling device.
Machine Control Forward Machine Control Broadcast
Machine Control Reverse DataXY

8Rev 1.7 • 18 Aug 10
2. Introduction
Functions
Machine Control Broadcast
This level type applies only to third-party router control systems. Use this level type if you have a
third-party control system and you want to be able to perform broadcast machine control takes.
DataXY
“DataXY” is a type of physical level on which data flow, much like video and audio signals in a
normal X/Y router. There is no concept of command and response on this type of level.
Port Types
Seven port types are available:
Controlling and Controlled
These port settings fix the direction of the router port to “controlling” or “controlled.” The port’s
connection for Tx and Rx is fixed. This allows the port to be routed as a source or destination while
maintaining, for example, Rx on pins 7 and 2 and Tx on pins 8 and 3.
SPins for Tx on a controlling machine are 8 and 3. Tx pins for a controlled machine are 7 and 2.
SFor more about machine control data, review the SMPTE 207M standard.
DTE
DTE has the same meaning for RS-232 as “controlling” does for RS-422.
DCE
DCE has the same meaning for RS-232 as “controlled” does for RS-422.
Dynamic
A dynamic port can be a controlling or controlled port depending on whether it is connected to a
master port or slave port. The port’s configuration is dynamic and can change during operation.
Dynamic ports are typically assigned to VTRs.
Master
Any dynamic port connected to a “master” port will be a controlled port.
The NV5256 applies logic to the port direction setting when a master port is connected to a
dynamic port. In this case, the machine at the dynamic port is always controlled and the machine at
the master port is always controlling.
A good example is an Avid editor controlling two VTRs.
Slave
“Slave” means the opposite of “master”: any dynamic port connected to a slave port will be a con-
trolling port.

2. Introduction
Installation
Summary
In general, a controlling machine must connect, through the router, to a controlled machine. That is
because Tx must connect to Rx and vice versa.
SIn NV9000-SE Utilities, when you add the NV5256 router to your system, set ‘Signal Type’ to
‘Machine Control’. Also set both ‘Output Protect’ and ‘Output Lock’ to ‘In Server’.
SIn NV9000-SE Utilities, when you configure a control panel, ‘semi-automatic’ is the preferred
setting for ‘XY data routing mode’. This is defined in the SE documentation:
“If the device to be acquired is already in use on the data level, alert the user —but allow the
user to perform the route by pressing ‘Take’ a second time. If ‘Take’ is not pressed again,
the route is cancelled. If the device is not in use, the take occurs automatically. This is the
recommended mode.”
The alternatives are ‘fully automatic’ and ‘manual’.
SIn NV9000-SE Utilities, you have the choice of making “source is master” the control panel
default or not.
Installation
The NV5256 is intended to mount in a standard 19-inch equipment rack. The frame is heavy
(approximately 100 lb, or 45 kg, fully loaded). Enlist the help of several persons during the mount-
ing process.
To help reduce weight, you can remove the power supplies and modules temporarily. Make note of
their location prior to removal. Do not drop or stack the modules.
To mount the equipment frame into a rack:
1 Swing the front door open all the way and then lift it up to remove it.
2 Lift the frame into the desired position within the rack. Have several helpers keep the frame in
position. Or use a jack.
3 Do not use the cards or other internal components as hand holds. Follow anti-static precautions
to protect the circuit boards. The handle on the bottom rear of the frame may be used for lifting
the frame.
4 Install rack screws into the 8 holes provided. It is important to use all 8 screw holes.
5 Replace any assemblies (power supplies, circuit cards) that you removed and replace the front
door.
The front rack-mounting brackets include keyway openings to accept an optional lifting bar. If you
wish, you can obtain a lifting bar by contacting your sales representative or Miranda Technical Sup-
port.

2. Introduction
Installation
SWarning: Make certain that your work area is free of unnecessary objects that block personnel
movement or that might interfere with their footing. Careless handling of the NV5256 frame
could result in personal injury.
SWarning: Disconnect power, if it is connected, before mounting the frame in the rack.
SWarning: The NV5256 draws cooling air from the front through the door and exhausts it at the
top rear edge of the frame. Make certain that airflow is not blocked at these locations. If air flow
is restricted, overheating may occur. The frame must have its door installed and closed for
proper airflow through the chassis. Filters are located on the inside of the door assembly and
should be maintained regularly.
SRear panel cover plates (placed in backplane slots that have no backplanes) are essential for
cooling. Although you can remove them temporarily, make sure that unused backplane slots
have cover plates during normal operation.

3. Detail
Chapter 3 describes the structure and use of the NV5256 Machine Control Router. It presents the
following topics:
•Connections
•Alarms
•Power
•I/O Cables
•Port Cards
•Expansion
•Terminators
•Jumpers
Connections
The rear of the router has a bay that holds up to 16 I/O backplanes. Unused backplane slots are gen-
erally covered with a plate that improves cooling air flow. Each backplane has 16 RJ-45 connec-
tors. All the backplanes are identical, but the I/O cards are of two types: RS-422 and RS-232.
SPorts on a single card are either all RS-422 or all RS-232.
To the left of the backplanes are a variety of control connectors and reference connectors. To the
right of the backplanes are expansion connectors and power connectors.

Connections
Control Ports
At the top left portion of the rear of the NV5256 frame are 6 DE9 connectors, and further below
that are 2 Ethernet connectors:
SA secondary (router) control card is for redundancy and is not required. If you have an
expanded system (two router frames), make connections only to one frame. The frame to which
you make connections is the “master” frame and it controls the second frame.
Serial Control
The CTRL1 and CTRL2 ports are DE9, female, RS-422. See Control Port Connectors, page 43, for
their pinout information.
You can use these connectors for control using a serial protocol from (1) a primary or secondary
NV9000 router control system, (2) a primary or secondary third-party router control system, or (4)
a router automation system.
Cases:
1 If you are using an NV9000 control system with a serial protocol or if you are using a third-
party control system, connect the primary CTRL1 port to a COM port on the control system’s
server. Similarly connect the secondary CTRL1 port if your router has a secondary control card.
2 If you have a redundant server, connect the primary CTRL2 port to a COM port on the redun-
dant server. Similarly connect the secondary CTRL2 port if your router has a secondary control
card.
3 If you do not have a redundant server, but have an automation system, connect the primary
CTRL2 port to a COM port of the automation system. Similarly connect the secondary CTRL2
port if your router has a secondary control card.
