1 General
The BDS-1616RC is a 16x16 serial digital video router with vertical interval switching, and output
reclocking. This state of the art router provides maximum quality with a data rate of up to 540Mbps,
automatic cable equalising on all inputs. High performance circuits in SMD technology assure
undiminished signal quality. The BDS-1616RC is well suited 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, with its many operational features. The control bus technology allows
linking the unit with the BAS-1616 or BES-1616 to create an AFV router. One or several Triton remote
control panels can control the BDS-1616RC as well. Another unique feature of the Triton 16x16 series is
the possibility to reconfigure the router via the configuration switch on the back plane to create several
formats of routers:
16x16 Serial Digital Video 1 layer
8x8 Serial Digital Video 2 layer
5x5 Serial Digital Video 3 layer
4x4 Serial Digital Video 4 layer

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 BDS-1616RC is normally delivered with the desktop power model AC ±5V / 30W. Upon customer
request, BDS-1616RC 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 BDS-1616RC router requires +5V DC with a minimum
current of 3.5A. The following pin-out is used on the DB9 male power connector:
Pin 1 and 9 0V
Pin 2 and 5 +5V
1Network Control Bus. The protocol of this bus is equal, and compatible to the MIDI bus protocol.

3 Connecting the BDS-1616RC 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
Pin3 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.

BDS-1616RC 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 BDS-1616RC router utilises 5-PIN
DIN connectors for connecting to the NCB. This means that when you connect your BDS-1616RC 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 BDS-1616RC 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.

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

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
Switch 1 - 4 on the configuration switch 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.

5.3 Vertical interval trigger
The BDS-1616RC router provides vertical interval switching. If vertical interval switching is desired you
have to connect an analogue VIT reference signal to the VIT input.
Switch 7 on the configuration switch enables or disables the VIT sensing on the VIT input. If VIT
switching is enabled but a proper signal is missing, the router will automatically switch without VIT.
The VIT can be switched according to the following pattern:
- means switch down
* means switch up
Switch 7 VIT
- disabled
* enabled
Default is VIT enabled.
