Model 5110
Mic/Line Input Module
implemented in the Model 5110’s firmware,
it’s possible in the future it may be. Contact
the factory for details.
Using an optional remote access module,
up to sixteen Model 5110 modules can
be remotely monitored and controlled. Us-
ing the remote access module’s Ethernet
interface and SNMP MIB objects, person-
nel using “GUI” applications or remote
control systems will be able to access all
the Model 5110’s functions, including input
sensitivity, phantom power on/off, and
pushbutton switch lock out. A local 2-wire
RS-485 data bus is used to interface the
remote access module with the one or
more Model 5110 Mic/Line Input Modules.
Installation
Integration of the Model 5110 into the
selected application is quite simple, only
requiring connecting to the analog and
digital audio outputs along with DC power.
Some applications will also require con-
nection to the RS-485 data bus. The audio
signals have a nominal level of either +4
or 0 dBu, depending on the Model 5110
version being installed. The DC power
source is nominal 12 volts with an accept-
able range of 10 to 18 volts. The RS-485
data bus is a single pair of wires that would
interconnect the Model 5110, along with
other Model 5100-Series modules, to a
remote access card. After the connec-
tions have been completed, the module
can then be secured into the designated
mounting location.
Analog Audio Outputs
Associated with each of the Model 5110’s
two audio output channels is a balanced
(differential), line-level analog output. The
circuitry is electronically balanced and ca-
pacitor coupled. The nominal output level
of a Model 5110S (SMPTE) version mod-
ule is +4 dBu with a maximum output level
of +24 dBu. The nominal level of a Model
5110E (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 5110’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.
When interfacing the outputs to unbal-
anced inputs on associated equipment
connect only to the Model 5110’s signal
+ (high) and common/shield. Do not make
any connections to the Model 5110’s
– (low) terminals.
Units with serial numbers in the range
of 00151 to 00200 (red-colored circuit
boards) should be connected following the
details in Figure 2.
Units with serial numbers of 00201 and
later (black-colored circuit boards) should
be connected following Figure 3.
