1 General
The BVS-6464 is a 64x64 video router with vertical interval switching. This state of the art router
provides 125MHz video bandwidth. High performance circuits in SMD technology assure undiminished
signal quality. The BVS-6464 is designed for all demanding routing tasks in digital studio and broadcast
environments. The built-in RS-232 interface allows the user to control the router via the Triton Router
Control System PC software with many operational features. The control bus allows linking the unit to
the BAS-6464 or BES-6464 video router thus creating a 64x64 AFV router. Several units can be
combined to form RGB, VGA or other larger matrix systems. One or several Triton remote control panels
can control the BVS-6464 as well. Another unique feature of the Triton 64x64 series is the possibility to
reconfigure the router via the configuration switch on the back plane so that the unit can be several types
of routers:

2 Power connection
Do not connect mains to the desktop power supply before connecting the power supply to the
router.
Connect the DB9 female connector from the desktop power supply to the main unit. Tighten the screws to
assure a proper contact. To connect mains to the desktop power supply you need a mains cord with IEC
320 connector.
The BVS-6464 is normally delivered with the desktop power model AC ±5V / 25W. Upon customer
request, BVS-6464 can also be delivered with DC ±5V / 30W, which may be fed by a 36 – 72 VDC
mains power source. A Frame mounted power supply solution is also available.
Please refer to the latest Triton Product Catalogue for power supply types, or call Thomson Grass Valley
for this information.
If any third party power supply is used the BVS-6464 router requires ±5V DC with a minimum current of
1.5A, (+5V/1.5A and –5V/1.5A). The following pin-out is used on the DB9 male power connector:
Pin 1 0V
Pin 2 +5V
Pin 6 -5V
3 Connecting the BVS-6464 to your PC
For connection to a PC with Triton Router Control System, the RS-232 interface is used. The RS-232 port
on all Triton devices uses the standard DCE pin-out, see pin-out table under 4.3.
A standard modem cable can be used for connecting the router to the PCs serial port.
3.1 Selection of router level
The router level depends on the system configuration the router is going to work with. See chapter 5 for
more information. All routers are delivered with default level 1. Triton Router Control System offers the
control of up to 16 different routers or combinations of routers.
3.2 Pin-out of RS-232 connector
The DB9 female connector for the RS-232 port has the following pin-out:
Pin 2 Tx
Pin 3 Rx
Pin 5 GND
3.3 Maximum cable length
The maximum cable length for an RS-232 connection is per definition 15m. Longer distances can be
installed depending on the environmental conditions of the installation site. It is the responsibility of the
installer / user to secure a proper installation of the RS-232 connection.

BVS-6464 Rev. 2

4 NCB connection
Via the Network Control Bus system several routers and control panels can be interconnected.
The standard MIDI interface is used on all NCB control ports. The BVS-6464 router utilises 5-PIN DIN
connectors for connecting to the NCB. This means that when you connect your BVS-6464 router to other
Triton devices, with RJ45 connectors, an RJ45 to 5-pin DIN interface is necessary.
This converter can be ordered from Thomson Grass Valley.
The NCB system allows connection of up to 16 routers with different levels on the same bus. Control
panels dedicated to work with a specific router must be configured to the same level as the router. Several
panels can work together with one specific router. Up to 16 single routers or combinations of routers can
be controlled from the Triton Router Control System. The NCB system and all RS-232 ports interchange
the system status.
4.1 Several routers in one system
The NCB system allows the interconnection of up to 16 routers with different levels in one system. A
combination of routers working married counts as one level. This might for example be 1 audio router + 1
video router working as an audio follows video system or 3 video routers working as an RGB (YUV)
system. The routers in such a constellation must be configured to the same level.
4.2 Connecting control panels
To get a control panel working with a specific router, configure the control panel to the same level as the
router. Several panels can be configured to control the same router. The Triton panels can control 2 levels
with breakaway function. If it is necessary to control more levels with breakaway an additional panel
must be used. Panels can also be connected to a router via the RS-232 interface. Please refer to your
control panel manual for installation.

4.3 Pin-out and cable type
4.3.1 RJ45 connectors
On some Triton devices, the NCB cable can be connected to RJ-45 connectors. The following pin-out is
used:
Pin 1 = Not Connected
Pin 2 = Not Connected
Pin 3 = Not Connected
Pin 4 = data
Pin 5 = data
Pin 6 = Not Connected
Pin 7 = Not Connected
Pin 8 = Not Connected
4.3.2 5-pin DIN connectors
However, the pin-out of most Network Control Bus ports, including that of the BVS-6464 follows the
standard MIDI specification. A 1:1 cable with 5pin DIN connector is used. The following pin-out is used:
Pin 1 = Not Connected
Pin 2 = shield
Pin 3 = Not Connected
Pin 4 = data
Pin 5 = data
The standard MIDI specification recommends the use of shielded twisted pair cable types for
interconnection between the units.

BVS-6464 Rev. 2

4.3.3 RJ45 to 5-pin DIN converter
In configurations that include both devices with RJ45 connectors, and devices with 5-pin DIN connectors,
an RJ45 to 5-pin DIN converter may be used to complete the control loop. This converter holds both
connector types, and may work both ways, thus from RJ45 to 5-pin DIN, as well as from 5-pin DIN to
RJ45.
The converter is connected as follows:
RJ45 (Router/CP) RJ45 (Converter) 5-pin DIN (Converter) 5-pin DIN (Router/CP)
IN IN IN OUT
OUT OUT OUT IN
4.4 Control bus structure
The Network Control Bus structure follows the standard MIDI bus definition. The NCB is defined as a
closed chain of units. This means that the NCB OUT of the last unit must be connected to the NCB IN of
the first unit in the NCB chain. To avoid problems with the control of Triton units the installer/user has to
assure that the bus structure is installed according to this definition. The total number of Triton devices in
an NCB chain is limited to 20.
4.5 Maximum distance between NCB devices
The standard MIDI definition allows a maximum cable length of 250 meters between two devices.
Longer distances can be made with MIDI repeater units. To avoid grounding problems all NCB ports
have opto-coupled inputs.
4.6 Control Bus configuration notes
In order to achieve a system that is easy to maintain and control, follow the important notes, presented
hereunder.
• Avoid using routers of different size, but same signal type (audio/video), on the same level.
Example: Do not configure a system with a BVS-1616 and a BVS-0808 on the same level. If they
were on the same level, crosspoint commands that were sent to the BVS-1616 lying outside the
range of the BVS-0808 would not be executed; the BVS-0808 would throw them off the bus.
However, a combination of a BVS-1616 and an BAS-0808 will work well, because commands are
different for video- and audio routers.
• Try to limit the number of devices on one Control Bus loop. If possible, separate systems that are
not to be controlled by one central control panel.
If you need to have several systems in one loop, try to separate as follows, using the DIP switches
on the rear of the devices:
o Analogue Video + Analogue Audio + CP for analogue system on Level 1
o SDI + AES/EBU + CP for digital system on Level 2
o RS-422 Data + CP for data on Level 3

BVS-6464 Rev. 2

o Universal Control Panel to control all devices above, with user configurable default level.
• Pay attention to the figure below, in order to achieve full controllability of all devices in the loop.
Triton - RCS
• Complete the Control loop, by connecting all Control bus connections to all Triton devices, before
powering up any Triton device.

5 Router configuration
5.1 Router level
Switches 1 - 4 on the configuration switch SW A set the router’s level for communication with the Triton
Router Control System, and other units in the NCB system. The panels on the NCB dedicated to operate
with the router must be configured to the same level as that router.
If several routers are combined to form an audio follows video, RGB or similar system, these routers
must be configured to the same level.
The levels can be switched according to the following pattern:
- means switch down
* means switch up
Default level is 1.
Switch 1 2 3 4 Level
- - - - 1
- - - * 2
- - * - 3
