Mic/Line Input Module
Digital Audio Output
The Model 5110’s two audio output chan-
nels are available in digital form by way 
of a DIN 1.0/2.3-compliant receptacle. 
This receptacle is located adjacent to 
the analog audio output connector. This 
is an AES3-compliant unbalanced 75 ohm 
signal that will transport audio, when using 
good-quality coaxial cable, several thou-
sands of feet.
The digital audio output signal has a 
sample rate of 48 kHz and a bit depth of 
24. The nominal level of the digital au-
dio output is –20 dBFS for Model 5110S 
(SMPTE) modules and –18 dBFS for 
Model 5110E (EBU) modules.
DC Input and Data Bus
A 4-position header is used to connect DC 
power and a local RS-485 serial data bus 
to the Model 5110. Two pins on the mating 
connector are used to connect a source 
of nominal 12 volts DC. The acceptable 
range is 10 to 18 volts DC with a maximum 
current of 300 milliamperes at 12 volts DC. 
For remote control operation two pins on 
the mating connector will implement the 
data bus connection from a Studio Tech-
nologies’ Model 5190 Remote Access 
Module.
The mating connector is compatible with 
the AMP MTA-100 series of IDC recepta-
cles. For 22 AWG wire the closed-end-style 
receptacle is AMP 3-643813-4; the feed-
through-style receptacle, used for busing 
connections, is AMP 3-644540-4. The body 
color for both receptacles is red, following 
the convention of the MTA-100 series for 
compatibility with 22 AWG wire. Refer to 
Appendix A of this guide for additional 
connector details.
Mounting
The Model 5110 is intended for mount-
ing into an installation-specific enclosure 
or rack panel. Refer to Appendix B for the 
unit’s dimensions and mounting screw 
locations. Please contact the factory to 
discuss mounting options.
Configuration
RS-485 Address
A data bus address must be configured 
for applications that implement remote 
control of Model 5110 functions. While up 
to 16 Model 5100-Series modules can 
“share” the RS-485 data bus, each module 
must have a unique address. Selecting the 
device’s address involves setting four con-
figuration switches located on one side of 
the module. The switches are a “piano key” 
type with their up position being defined as 
off and their down position defined as on. 
Refer to Figure 4 for details.
