1Product overview
The DA-T140 is a serial digital distribution amplifier module providing high performance
media distribution for various signal formats from 1Mbps up to 540Mbps. The unit is
specially designed to handle 140Mbps and 155Mbps and can be configured to do cable
equalising of ITU-T G.703 signal formats.
The input typically provides an automatic cable equaliser for up to 250 metres of cable
(Belden 8281A at 140Mbps) with 6 outputs. All 6 outputs are non-inverting.

On DA-SDI-C2 the electrical input signal is connected to the IN BNC and the electrical
outputs are connected to the O1 to O6 BNC’s. Please note that outputs 1 to 6 are non-
inverted, while outputs 7 and 8 are not available.

Unused outputs should be terminated with 75 ohm.
DA-SDI-C2 does not have any GPI alarm outputs.
All unused outputs should be terminated.
4.1 Mounting the connector module
The details of how the connector module is mounted, is found in the user manual for the
sub-rack frame FR-2RU-10-2.
This manual is also available from our web site: http://www.network-electronics.com/.

5Module status
The status of the module can be monitored in three ways.
1. GYDA System Controller (optional).
2. GPI at the rear of the sub-rack.
3. LED’s at the front of the sub-rack.
Of these three, the GPI and the LED’s are mounted on the module itself, whereas the GYDA
System Controller is a separate module giving detailed information on the card status. The
functions of the GPI and the LED’s are described in sections 5.1 and 5.2. The GYDA
controller is described in a separate user manual.
5.1 GPI Alarm – Module Status Outputs
These outputs can be used for wiring up alarms for third party control systems. The GPI
outputs are open collector outputs, sinking to ground when an alarm is triggered. The GPI
connector is shown in Figure 7.
Electrical Maximums for GPI outputs
Max current: 100mA
Max voltage: 30V

Appendix A Materials declaration and recycling information
A.1 Materials declaration
For product sold into China after 1st March 2007, we comply with the “Administrative
Measure on the Control of Pollution by Electronic Information Products”. In the first stage of
this legislation, content of six hazardous materials has to be declared. The table below
shows the required information.
Toxic or hazardous substances and elements

O: Indicates that this toxic or hazardous substance contained in all of the homogeneous materials for
this part is below the limit requirement in SJ/T11363-2006.
X: Indicates that this toxic or hazardous substance contained in at least one of the homogeneous
materials used for this part is above the limit requirement in SJ/T11363-2006.
A.2 Environmentally-friendly use period
The manual must include a statement of the “environmentally friendly use period”. This is
defined as the period of normal use before any hazardous material is released to the
environment. The guidance on how the EFUP is to be calculated is not finalised at the time
of writing. See
http://www.aeanet.org/GovernmentAffairs/qfLeOpAaZXaMxqGjSFbEidSdPNtpT.pdf for an
unofficial translation of the draft guidance. For our own products, Network Electronics has
chosen to use the 50 year figure recommended in this draft regulation.
Network Electronics suggests the following statement on An “Environmentally Friendly Use
Period” (EFUP) setting out normal use:
EFUP is the time the product can be used in normal service life without leaking the hazardous
materials. We expect the normal use environment to be in an equipment room at controlled
temperature range (0ºC - 40ºC) with moderate humidity (< 90%, non-condensing) and clean air, not
subject to vibration or shock.
Further, a statement on any hazardous material content, for instance, for a product that uses
some tin/lead solders:
Where a product contains potentially hazardous materials, this is indicated on the product by the
appropriate symbol containing the EFUP. The hazardous material content is limited to lead (Pb) in
some solders. This is extremely stable in normal use and the EFUP is taken as 50 years, by comparison
with the EFUP given for Digital Exchange/Switching Platform in equipment in Appendix A of “General
Rule of Environment-Friendly Use Period of Electronic Information Products”. This is indicated by the
product marking:
50
It is assumed that while the product is in normal use, any batteries associated with real-time clocks or
battery-backed RAM will be replaced at the regular intervals.

DA-T140 Rev. 6
The EFUP relates only to the environmental impact of the product in normal use, it does not imply that the
product will continue to be supported for 50 years.
A.3 Recycling information
Network Electronics provides assistance to customers and recyclers through our web site
http://www.network-electronics.com. Please contact Network Electronics’ Customer Support
for assistance with recycling if this site does not show the information you require.
Where it is not possible to return the product to Network Electronics or its agents for
