Model 5110
Mic/Line Input Module
Remote Control Capability
With an optional Model 5190 Remote
Access Module up to 16 Model 5110 mod-
ules can be remotely monitored and con-
trolled. Using the 5190’s Ethernet interface
personnel using a standard web browser
will be able to access all the Model 5110’s
standard functions, including input sensitiv-
ity, phantom power on/off, and pushbutton
switch lock out. In addition to the standard
functions, the 5190 will allow more features
to be utilized. These include expanded
input sensitivity adjustment, channel text
labeling, and module identification. A lo-
cal 2-wire RS-485 data bus is used to
interface the Model 5190 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. Refer to Figure 2 for details.
For details on appropriate mating connec-
tors refer to Appendix A 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.
