Master Control • Device Controller User’s Guide 1
1. Device Controller
Miranda offers a third-party “device controller” as an adjunct to its master control system. It is a
DC21 from DNF Controls. Because it is third-party equipment, support for it is limited.
This brief guide augments the documentation from the manufacturer.
Introduction
The “device controller” is a IRU device, 8.5″deep, that has 32 optically isolated inputs and 32 relay
outputs (also optically isolated) and 4 serial ports.
Figure 1-1. Device Controller, Front View
Figure 1-2. Device Controller, Rear View
SThe product is a DC21 even though its front panel says DC20.
The device controller receive signals from an MCE using Miranda’s NVISION Ethernet protocol
(NVEP). Under master control, the DC21 sends device control messages to VTRs and other media
either through its GPIO outputs or through its serial ports. A single DC21 can control up to 16
source devices using its GPIO ports and up to 4 source devices using its serial ports.
The serial ports communicate with controlled devices using a serial protocol. Protocols supported
are Sony, Odetics, and VDCP.
The GPIO ports communicate with controlled devices using simple on/off switching.
Multiple device controllers can be connected together over the master control network. An MCE
can address only the one device controller for which it is configured. MCEs can be configured for
pre-roll and machine control independently. MCEs configured for pre-roll but not configured for
machine control do not use the DC21.
The device controller itself is configurable with a small self-contained application that runs in a
browser such as Internet Explorer. The objective of configuration is to define the serial ports and to
set GPIO switching parameters.

You may ignore any of the ports not identified in this illustration.
Use the GPO connectors (DC37s) to wire GPO device control connections. See Connectors on
page 17 for the pinouts.
Use the Ethernet #1 connector (RJ-45) to connect the DC21 to your master control network.
Use the serial connectors (DE9s) to wire serial device control connections. The serial ports can be
configured for RS-232 or RS-422 communication, but RS-422 is more widely used. See Connec-
tors on page 17 for the pinouts.
SUp to 4 control panels may communicate with any one MCE.
It is recommended that you connect the ground terminal to earth ground, but not strictly necessary.
Connect your facility’s video reference to the video reference connector. Connect your facility’s
time-code source to the LTC connector. The LTC uses a 3-pin Phoenix quick-release connector. See
Connectors on page 17 for its pinout.

Initial Setup
Initial Setup
SCaution: do not apply AC voltage to the power supply and then connect the power supply to the
DC21. Component damage can occur.
This is the basic procedure.
1 Plug in the device controller at the power connection. Use the external power supply provided.
2 Use a CAT5 Ethernet cable to connect the device controller to the Ethernet switch servicing the
master control network. Use the port labeled “E-net #1.”
Using the front panel of the device controller, enter its IP address on the master control network
and verify that its mask is 255.255.255.0.
3 Cable the GPIOs (on the 4 DC37 connectors) to whatever devices you are using according to
the design of your system. See Connectors on page 17 for the pinouts.
4 Using your configuration PC (presumed to be on the master control network already), launch
your browser (e.g., Internet Explorer). Enter the IP address of the device controller as the URL:
http://192.168.102.112 (This is just an example)
The device controller will run its self-contained configuration application in which you may
configure the device controller’s inputs and outputs.
Before you can configure anything, you must enter your ID and password. The default or initial
ID and password are (admin, controls). You can change the ID and password.
(You can change the time and date using the ‘System’ option of the configuration software.)
Connect house video reference to the video reference input at the rear.
Entering IP and Mask
The front panel has a 2×16 character display and 8 function buttons.
Four of the function buttons (at the left) are arrows. The sixth button is ‘Enter’. These buttons are
used to navigate through the device controller’s menu system.
To scroll through the list of options, press the up or down arrows until you come to an option you
want to set or change.
Set the IP address
Scroll up or down so that the display shows ‘Current IP1’. Press ‘Enter’.
An underline cursor appears at the first digit of the IP address. Use the left and right arrows to move
to a digit you want to change. Then use the up/down arrows to change the value of the digit. When
you have finished, press ‘Enter’ once again.
SPressing the ‘Esc’ button terminates the operation and leaves the value unchanged.
Do the same for the IP subnet mask. (The display should read ‘Current Mask1’.) The value should
be 255.255.255.0.

‘Enter’ again to confirm your choice.
Press the ‘Esc’ button any time to cancel your operation.
Using the Configuration Tool
When you launch the internal DNF configuration tool in your browser, its initial screen is this:
It presents 7 options (sub-pages) listed across the top in the yellow region:
Only 4 of these are of any use to master control.
Protocol assignment Define connections to devices controlled through the serial ports.
GPI The GPIs are not used for master control.
GPO Configure any or all of the 32 GPOs.
Event notification Ignore this unless you have a USP.a
a. Miranda does not provide any support for the USP (Universal Switch Panel) —a separate DNF product.
USP events Ignore this unless you have a USP.
Event monitoring You may ignore the ‘Event Monitoring’ table unless you want to trigger GP
outputs based on certain inputs. This table is not used for master control.
System Presents a login dialog and provides configuration options for the device
controller (to which you are connected) and its software.

Master Control • Device Controller User’s Guide 5
1. Device Controller
Using the Configuration Tool
Each sub-page manages a configuration table. Configuration tables can be saved and retrieved for
fast setups and quick changes during broadcast or production.
Descriptions of the sub-pages follow.
System
If you are not logged in, clicking the ‘System’ option presents a login dialog:
The default ID is admin and the default password is controls.
SThe login times out after a few minutes. After any period of non-use, you might find the config-
uration tool asking for your password again.
After you are logged in, the ‘System’ option presents a list of configuration options (where you can
set your password, among other things).
Other than password and system time, most of the items in this page are of little concern.
Logout
The logout entry on this page logs you out of the application immediately. Be careful if you do not
know the password. (The default password is controls.)
Logging out prevents unauthorized persons from making changes.

Protocol Assignment
The device controller supports up to 4 serial channels (on the 4 serial ports). This table on this page
lists the channels and defines the parameters for each channel.
The example in this illustration shows all 4 channels defined. Two use Sony protocol and the others
use Odetics and VDCP:
You can edit the table, but you cannot add or delete items. Of the entries in the table, ‘PHY Config’

Device Internal Latency
Master control is very much concerned with ‘Device Internal Latency’. In any of these tables, you
must ignore ‘Preroll Delay’ here because pre-roll delay is handled by master control internals.
Device latency is typically 4–10 frames. You will have to determine the device latency for each of
your devices by experimentation.
SIf you change the ‘Device Internal Latency’ value, it is then necessary to reboot the DC21 to
inform the MCE of the new value. Also, whenever the DC21 is rebooted, all attached VTRs
must be powered on or the DNF box will not report this latency value to the MCE!
Pre-Roll Delay
Always set all values in this column to 0. Pre-roll delay is handled in MasterConfig.
Time Base
The choices are DF (drop frame), NTSC, and PAL.
VDCP Port
This field identifies a port within the device under control.
TSO
TSO means “tape speed override.” You can potentially enter a value up to ±25%. However, TSO is
not used in master control. You should use the default values.
Click ‘Save’ to confirm your entries. Click ‘Done’ to save your entries and return to the ‘Protocol
Assignment’ page.
PHY Config
The ‘Protocol Assignment page has are two ‘PHY Config’ options: view or edit. The options are
not available for unassigned channels.
Click ‘View’ for the channel if you want only to examine its parameters

Click ‘Edit’ for a channel if you want to change its parameters
Choose the appropriate Baud rate and bit pattern for the device controlled by this channel.
Typical values, and especially for Sony and Odetics protocols, are 38400 Baud, 1 stop bit, 8 data
bits, and odd parity. RS-422 is the more common serial mode.
Choose ‘Controller’ in the ‘Operation Mode’ field.
Click ‘Save’ to confirm your entries. Click ‘Done’ to save your entries and return to the ‘Protocol
Assignment’ page.
GPI
The DC21’s GPIs are not used for master control.
GPO
The device controller’s GPO option presents a table of 32 GPIOs (outputs):
You cannot add or delete outputs, but you can edit them. The other options at the top of the page
include:
Backup Save your GPO configuration to a file (on your PC).
Restore Retrieve the GPO configuration from a saved file.
Create Default Reinitializes the device controller’s GPOs to a default configuration.
(You’ll get a warning “Are you sure.”)

(See the diagram next page.)
ON State ‘Relay Closed’ means that the output state is considered “on” when NO
and COM are connected. ‘Relay Open’ means that it is “on” when NO and
COM are not connected. (There is no NC position.)
See Connectors on page 17 for the connector pinouts.
Mode Switching options are latched and momentary. Normal GPOs are latched.
A momentary GPO produces a pulse. A 100 ms pulse is generally suitable
for performing VTR control.
The MCE sends a pulse of 3 video frames (about 100 ms). To support the
MCE’s pulse, choose “latched.” If you choose “momentary,” you can set a
different pulse width. We recommend that you choose “latched.”
On Time “On time” applies to momentary GPOs and is expressed in multiples of
10 ms.
Transition Delay The amount of time from the triggering event to the change of the relay
state. The transition delay is expressed in multiples of 10 ms.
Debounce Debounce options are expressed in multiples of 16 ms (not 10ms). A “1”
means 10 ms; a “2” means 20 ms, and so on.
The ‘Current State’ column tells you the logical state of the outputs (at the time of sampling).
Labels are useful, but not essential.
You must click the ‘Refresh’ button to resample the outputs.
The maximum for any of the time fields is 255.
Event Monitoring
The ‘Event Monitoring’ table defines the effects of events. Events include (1) GPI state changes
and (2) serial channel events. This is a list of serial channel events:
Cue Ffwd Loaded Pause Play
Record Rwd Shut fwd Shut rev Stop
These event types apply to each of the DC21’s 4 serial channels.

12 Rev 1.0 • 29 Nov 11
1. Device Controller
Using the Configuration Tool
The effects can be either GPO changes (on, off, or toggle) or channel state changes. These are the
channel changes supported by the DC21:
Play Pause Ffwd Cue to ‘in’ Slomo 25 Fwd Slomo 50 Fwd
Stop Recue Rwd Play rev Slomo 25 Rev Slomo 50 Rev
Again, they apply to each of the 4 serial channels. Note that master control does not use “slomo.”
Each row in the event table couples one event (GPI or channel event) to one effect (GPO or channel
state change).
SThere is no combinational logic (as there is in the tally processor).
For each event monitored, the table specifies what to do and which GPO to trigger (and whether to
trigger it) when the event occurs.
When you add an event to this table, you define the label (a unique ID) for the event.
An event is considered ON when its underlying definition evaluates ON. It is OFF, otherwise.
SPending events do not result in any action.
In most cases, you do not want to configure any events at all —especially not those that cause
changes to the state of controlled devices. That will interfere with master control operations.
However, if you have spare GPOs and want to use them, the event monitoring table can be useful.
Adding Events
An event dialog appears when you choose ‘Add’ (above or below the table).
An event may be local or remote. If it is remote, enter the IP address of the remote device controller
and the remote label for the event. If it is local, the label drop-down list will be filled with a number
of options which include GPIs and serial port events.
