Model 5130
Party-Line Interface Module
have a nominal level of either +4 or
0 dBu, depending on the Model 5130 ver-
sion being installed. The DC power source
is nominal 12 volts with an acceptable
range of 10 to 18 volts. The RS-485 data
bus is a single pair of wires that would inter-
connect the Model 5130, along with other
Model 5100-Series modules, to a remote
access card. After the connections have
been completed, the module can then
be secured into the designated mounting
location.
Audio Inputs
The Model 5130 allows two channels of
analog line-level audio to be connected.
Each signal is associated with one of the
two party-line interface channels. The input
circuitry is electronically balanced and
capacitor coupled. The nominal input level
of Model 5130S (SMPTE) version modules
is +4 dBu with a maximum allowable input
level of +24 dBu. The nominal input level
of Model 5130E (EBU) version modules
is 0 dBu with a maximum allowable level
of +18 dBu.
Connections to the audio inputs are
made using a 5-position header connector
located on the Model 5130’s rear-most
circuit board. For details on appropriate
mating connectors refer to Appendix B
located at the end of this document.
For connecting to balanced sources the
signal + (high), signal – (low), and common/
shield connections should be used. With
unbalanced sources connect source signal
high to the Model 5130’s signal + (high) and
source signal low to both the signal – (low)
and common/shield connections. Refer to
Figure 2 for details.
Audio Outputs
Associated with each of the Model 5130’s
two party-line interface channels is a bal-
anced (differential), line-level analog audio
output. The circuitry is electronically bal-
anced and capacitor coupled. The nominal
output level of a Model 5130S (SMPTE)
version module is +4 dBu with a maximum
output level of +24 dBu. The nominal level
of a Model 5130E (EBU) version module is
0 dBu with a maximum level of +18 dBu.
Connections to the audio outputs are
made using a 5-position header connector
located on the Model 5130’s rear-most
circuit board. For details on appropriate
mating connectors refer to Appendix B
located at the end of this document.
For connection to balanced inputs on
related equipment the signal + (high) and
signal – (low) connections should be used.
Pin 1, common/shield, may or may not
need to be connected as dictated by the
specific installation. Refer to Figure 3 for
details.
When interfacing the outputs to unbal-
anced inputs on associated equipment
connect only to the Model 5130’s signal
+ (high) and common/shield. Do not make
any connections to the Model 5130’s
– (low) terminals.
