Preface
Restriction on Hazardous Substances (RoHS) Directive
Directive 2002/95/EC—commonly known as the European Union (EU)
Restriction on Hazardous Substances (RoHS)—sets limits on the use of
certain substances found in electrical and electronic equipment. The
intent of this legislation is to reduce the amount of hazardous chemicals
that may leach out of landfill sites or otherwise contaminate the
environment during end-of-life recycling. The Directive, which took
effect on July 1, 2006, refers to the following hazardous substances:
•Lead (Pb)
•Mercury (Hg)
•Cadmium (Cd)
•Hexavalent Chromium (Cr-V1)
•Polybrominated Biphenyls (PBB)
•Polybrominated Diphenyl Ethers (PBDE)
According to this EU Directive, all products sold in the European Union
will be fully RoHS-compliant and “lead-free.” (See our website for
more information on dates and deadlines for compliance.) Spare parts
supplied for the repair and upgrade of equipment sold before
July 1, 2006 are exempt from the legislation. Equipment that complies
with the EU directive will be marked with a RoHS-compliant emblem,
as shown in Figure P-1.

Waste from Electrical and Electronic Equipment
(WEEE) Directive
The European Union (EU) Directive 2002/96/EC on Waste from
Electrical and Electronic Equipment (WEEE) deals with the collection,
treatment, recovery, and recycling of electrical and electronic waste
products. The objective of the WEEE Directive is to assign the
responsibility for the disposal of associated hazardous waste to either
the producers or users of these products. As of August 13, 2005,
producers or users are required to recycle electrical and electronic
equipment at end of its useful life, and may not dispose of the
equipment in landfills or by using other unapproved methods. (Some
EU member states may have different deadlines.)
In accordance with this EU Directive, companies selling electric or
electronic devices in the EU will affix labels indicating that such products must be properly recycled. (See our website for more information
on dates and deadlines for compliance.) Contact your local sales representative for information on returning these products for recycling.
Equipment that complies with the EU directive will be marked with a
WEEE-compliant emblem, as shown in Figure P-2.

Setting Jumpers and Adjustable Components
VCA6800+
The VCA6800+ module has four jumpers, which are used to select the
following modes:
•One jumper for looping or internal input termination
•Two jumpers for AC or DC coupling mode
•One jumper for soft-, hard-, or no-clamping mode
The VCA6800+ module also has adjustable potentiometers (“pots”) for
Gain and EQ modes.

Setting the Input Terminating Jumper
Follow this procedure to set the jumper for looping or internal input
Note
In a DM frame, you can create
looping inputs by adding a
T-connector on the input
connection and changing the
input termination mode jumper
setting to external termination.
(The internal termination setting
is used for non-looping inputs.)
For BMFL modules, the input
termination jumper default
mode is for external
termination. This is the setting
you will need if you are using a
looping input.
termination:
1. Locate the jumper block on the module. Figure 2-1 on page 17
shows the location of this jumper block.
2. Place the jumper on the pin that corresponds to looping or internal
input termination. See Figure 2-2.
The VCA6800+ module has two separate, adjustable potentiometers
(“pots”) for gain and EQ mode adjustment. Figure 2-1 on page 17
shows the location of these pots.
A multi-turn pot allows you to adjust gain for a range of –3 dB to +3
dB. See Figure 2-5 on page 20.
•To increase the gain, turn the pot clockwise.
•To decrease the gain, turn the pot counterclockwise.
A second multi-turn EQ pot allows you to adjust cable equalization. See
Figure 2-5 on page 20.
•To obtain more equalization, turn the pot clockwise.
•For less equalization, turn the pot counterclockwise.

single-turn pot controls the response, while a variable capacitor controls
EQ response. The adjustments have been set in the manufacturing
facility; readjusting is not recommended without precision test
equipment.
The VDA6800+ module has one jumper, which is used to select the
looping or internal input termination. The VDA6800+ module also has
an adjustable pot for gain mode.

Adjusting Potentiometers
The VEA6800+ module has two separate, adjustable potentiometers
(“pots”) for gain and EQ mode adjustment. Figure 2-9 on page 22
shows the location of these pots.
A multi-turn pot allows you to adjust gain for a range of –3 dB to +3
dB. See Figure 2-11.
•To increase the gain, turn the pot clockwise.
•To decrease the gain, turn the pot counterclockwise.
A second multi-turn EQ pot allows you to adjust cable equalization. See
Figure 2-11.
•To increase equalization, turn the pot clockwise.
•To decrease equalization, turn the pot counterclockwise.
