BAS-1616 Rev. 2
1 General
The BAS-1616 is a 16x16 stereo audio router with balanced in- and outputs. This state of the art router
provides high performance circuits in SMD technology for maximum system performance. The
BAS-1616 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 BVS-1616 or
BDS-1616 video router thus creating a 16x16 AFV router. Two BAS-1616 can be combined to form a 4
channel audio router. One or several Triton remote control panels can control the BAS-1616 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 so that the unit can be several types of routers:
16x16 Balanced Stereo
8x8 Balanced 2 Channel Stereo
5x5 Balanced 2 Channel Stereo + Cue
4x4 Balanced 4 Channel Stereo

BAS-1616 Rev. 2
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 BAS-1616 is normally delivered with the desktop power model AC ±15V / 30W. Upon customer
request, BAS-1616 can also be delivered with DC ±15V / 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 BAS-1616 router requires +15V DC with a minimum current
of 400mA. The following pin-out is used on the DB9 male power connector:
Pin 1 0V
Pin 4 +15V
Pin 8 -15V
3 Connecting the BAS-1616 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.
2
BAS-1616 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 BAS-1616 router utilises 5-PIN DIN
connectors for connecting to the NCB. This means that when you connect your BAS-1616 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.

BAS-1616 Rev. 2
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 BAS-1616 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
BAS-1616 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
5
BAS-1616 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.

BAS-1616 Rev. 2
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.
Switch 1 2 3 4 Level

7 Control and connection of Triton systems, interface protocol
7.1 Important notes regarding the Triton Control Protocol
7.1.1 Binary Code
The strings shown on the next pages are in binary coded format. Please be aware of the fact that any
terminal program you may use to control a Triton unit from a PC must be able to generate hexadecimal
characters. ASCII characters will not be accepted.
7.1.2 Echo
A matrix will reply on a crosspoint set command with an ECHO. In the case where a crosspoint is already
set no ECHO will be sent. If the matrix is part of an NCB system two types of reply will be sent.
Immediately after receiving the crosspoint set command the ECHO will be sent. The matrix will then wait
for the command to pass the NCB system. After receiving the command from the NCB system the matrix
will send the command as an ACKNOWLEDGE.
7.1.3 RS-422 Matrixes
RS-422 Data Routers do not accept distribution of an input signal to several outputs. An input signal can
only be routed to one single output. The Firmware of our RS-422 routers takes care of these limitations. If
an input (Source) is already connected to a particular output (Destination) any connection of this input to
another output would disconnect the previous connection. The router will in this case send the following
message for the disconnected output: Output connected to input 128. Input 128 is an internal default for
the disconnect status. Please see Triton recommendations for use of RS-422 data routers for further
information.
7.1.4 Timeout
The Crosspoint Status Request message has a timeout, which means that you need to wait 1 second in
between request messages.
7.2 Basic principles
Any message on any level (address) that conforms to the standard arriving at either the NCB or the
RS232 port will be re-sent on both NCB and RS232. The only exceptions are:
a) A matrix that recognizes its address will not re-transmit the message if the crosspoint is already
set.
b) A matrix that recognizes its address will not re-transmit the message if the output number or input
number exceeds its size.
c) A unit (matrix or panel) will not re-transmit a message arriving at the NCB if it was re-transmitted
a short while ago (typically 0.5 sec). This is done by grabbing a message storing it for the timeout
period, and comparing it with new messages. After the timeout period the unit will grab a new
message for compare. This is done to remove unwanted (read: unknown) messages from the NCB
ring.
d) A message arriving at the RS232 will always be re-transmitted unless it is a matrix, and one of the
cases a) or b) is fulfilled.
7.2.1 Example: A single unit with no NCB connected
Messages sent to the RS232 of a single unit will be returned once no matter what address or input/output
number the message has, unless it is a matrix which recognizes one of the conditions a) or b) above.
12
BAS-1616 Rev. 2
7.2.2 Example: Several units connected by NCB
Messages sent to the RS232 of a single unit will be returned once no matter what address or input/output
number the message has, unless it is a matrix which recognizes one of the conditions a) or b) above.
If none of the cases a) or b) is fulfilled the message will also be transmitted on the NCB. Then if any unit
on the NCB ring recognizes any of the cases a)/b) or c), the message will stop at that point. This means
that the message will only be returned once on the RS232.
However, if none of the units on the NCB recognizes any of the cases a) to c), the message will return to
the originator (the unit which received the message on RS232). This unit will re-transmit the message
once more on both NCB and RS232. The message is therefore returned a second time on RS232. This
time one of the cases a) or c) is sure to be identified by one of the units on the NCB, and the message is
removed.
There is however one more special case: If several messages for unused addresses are transmitted with
only little delay, one might experience that some messages are returned several times, as the
store/compare/remove function in case c) can only handle a single message at the time. We therefore
recommend that the user avoid sending messages to unused addresses.
7.3 RS232
The RS-232 port is used for external control of Triton units. The RS-232 port allows the customer to
control the equipment via the Triton Router Control System PC program or self-defined customized
solutions.
Connector for the RS-232 port is a DS9 female.
Pin 2 - Tx.
Pin 3 - Rx
Pin 5 - GND
A standard DCE (Data Communication Equipment) cable can be used for connection between PC and
Triton equipment. The connection between the connectors is made one-to-one.
Data-rate is 19200 baud/sec with 8 data-bit, 1 stop-bit, no parity, if nothing else is specified in the user
manual of the product.
7.4 NCB
The NCB is used for interconnection between several Triton units. Up to 20 routers and/or control panels
can be linked together to form a routing system with many operational features.
The NCB utilises a 5 mA current loop with opto-coupled ports.
Standard connector is a 5pin DIN.
Standard MIDI cables can be used to interconnect several Triton units.
Data-rate is 31.25 Kbps.
1 start-bit, 8 data-bit, no parity, 1 stop-bit. Logical 0 = current ON.
