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.

BES-0808/75 Rev. 2

1 General

The BES-0808/75 is an 8x8 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-0808/75 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-0808 or BDS-0808 video router thus creating an 8x8 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-0808/75 as well. Another unique feature of the Triton 8x8 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:

8x8 AES/EBU 1 Channel

4x4 AES/EBU 2 Channel

2x2 AES/EBU 4 Channel

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-0808/75 is normally delivered with the desktop power model AC ±5V / 10W. Upon customer

request, BES-0808/75 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-0808/75 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

3 Connecting the BES-0808/75 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.
