Electromagnetic Radiation Notice
The following information is given to note compliance with the United States Government Federal Communications
Commission (FCC) Rules (47 CFR Part 15) designed to limit interference to radio and TV reception. The ruling establishes
measurement procedures and frequency criteria for Class A computing devices (commercial and industrial applications) with
the following conduction and radiation limits:
CLASS A COMPUTING DEVICE: CONDUCTION LIMIT (Part 15.812)
Frequency (MHz) Maximum RF Line Voltage (uV)
0.45 - 1.6 1000
1.6 - 30 3000
CLASS A COMPUTING DEVICE: RADIATION LIMIT (Section 15.810)
Frequency (MHz) Distance (meters) Field Strength (uV/m)
30 - 88 30 30
88 - 216 30 50
216 - 1000 30 70
The policy of Thomson is one of continual development and improvement. For that reason Thomson uses components and
manufacturing techniques that provide the current state-of-the-art suppression of electromagnetic radiation. This equipment, in
production before October 1, 1981, has not been tested to the above listed measurements. However, equipment such as this
delivered after October 1, 1983 will have the measurements on record at the factory. Therefore, in compliance with the stated
FCC Regulation, the following information is provided for the user:
NOTE
Interference to Radio Communications
This equipment generates, uses, and can radiate radio frequency energy and if not installed and used
in accordance with the instruction manual, may cause interference to radio communications. As
temporarily permitted by regulation it has not been tested for compliance with the limits for Class A
computing devices pursuant to Subpart J of of Part 15 of FCC Rules, which are designed to provide
reasonable protection against such interference. Operation of this equipment in a residential area
is likely to cause interference in which case the user at his own expense will be required to take
whatever measures may be required to correct the interference.

1 General
The BVS-3232 is a 32x32 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-3232 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-3232 or BES-3232 video router thus creating a 32x32 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-3232 as well. Another unique feature of the Triton 32x32 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:
32x32 Composite Video
16x16 Y/C (SVHS)
10x10 Beta / YUV
8x8 RGB/Sync

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-3232 is normally delivered with the desktop power model AC ±5V / 30W. Upon customer
request, BVS-3232 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-3232 router requires ±5V DC with a minimum current of
800mA. The following pin-out is used on the DB9 male power connector:
Pin 1 0V
Pin 2 +5V
Pin 6 -5V
1Network Control Bus. The protocol of this bus is equal, and compatible to the MIDI bus protocol.
