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 BES-1602/75 is a 16x2 AES/EBU digital audio router with unbalanced 75 Ohm in- and outputs. This
state of the art router provides high performance circuits in SMD technology for maximum system
performance. The BES-1602/75 is designed for all demanding routing tasks in digital studio and
broadcast environments. The BES-1602/75 offers the possibility to expand the router in the input
direction up to 64x2. 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-1602 or BDS-1602 video router thus creating a 16x2 AFV router. Several units can be
combined to form a 2 or more layer AES/EBU matrix system. One or several Triton remote control
panels can control the BES-1602/75 as well.

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 BES-1602/75 is normally delivered with the desktop power model AC ±5V / 10W. Upon customer
request, BES-1602/75 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 BES-1602/75 router requires ±5V DC with a minimum current
of 200mA. The following pin-out is used on the DB9 male power connector:
Pin 1 0V
Pin 2 +5V
Pin 6 -5V
3 Connecting the BES-1602/75 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.
