Overview
The Global MPI-2 rack unit is Lencore’s auxiliary page interface (MPI) to be used
for iNET systems. The Global MPI-2 is designed to make a global all-call page to
every building that has a Global MPI-2. Paging can be made via any telephone
on the network or a microphone. The Global MPI-2 works in conjunction with the
Local MPI-2. The Global MPI-2 rack is designed to fit into a standard 19” rack.
Features and Capabilities
•Front panel LEDs. Front panel LEDs indicate various functions and activity
of the unit.
•Analog phone input.
•Built-in speaker for testing/troubleshooting.
•Single turn pot to adjust the paging input signal level.
•Ability to connect a Local MPI.
Inputs
•Power input.
•Analog phone line input (RJ11).
•Ground 2-pos terminal block (screw terminals).
•Microphone inputs (individual wires and RCA).
Outputs
•Local MPI (RJ45).
1
•Activity - Rx – blinks when Neuron is receiving data Tx – blinks when
Neuron is transmitting data.
•Status – blinks every 8 seconds and solid when paging. Solid when an IR
remote button is pressed.
•Page On – solid during an active page.
•Audio input level – one set of three LEDs for paging input level detection.
Yellow = low or no input. Blue = good audio level. Red = audio input too
high.
LEDs
•Power – solid when the unit is powered.

Front Panel
1. Power LED
The power LED indicates power to the unit.
2. Activity LEDs
The activity LEDs indicate LON activity.
3. Page On/Off
Used to start and stop a page for audio connected to the MIC input.
4. Status/Page On LEDs
The status LED will flash every few seconds to indicate that the internal processor is operating.
5. Audio Level LEDs
The audio level LEDs indicate the audio input level for paging.
6. Input Page Volume
The input page volume adjustment is used to adjust the input page volume.

Rear View
7. To Local MPI
Connect an RJ45 cable to the Local MPI-2.
8. Mic Input 1
The 5-position MIC input is for a microphone input.
9. PTT for Mic input 2
Input for MIC PTT key switch.
10. Mic Input 2
Mic Line Level Input.
11. Phone
The RJ11/12 phone input is for a POTS appearance phone line.
12. GND (Audio Com)
Connect a single ground wire to the Local MPI-2 ground connector.
13. Power Input
Power cord connector (IEC 60320)
100-240VAC.

Wiring
To Local MPI
The “To Local” MPI connector is for communicating to the Local MPI.
Wire the “TO LOCAL MPI” to the Local MPI’s “TO GLOBAL MPI” connector using
an RJ45 cable. The Global MPI-2 cannot operate without the Local MPI-2.
Microphone Input
The microphone input is for a dynamic microphone.
Connect a microphone to the “MIC” connector using individual wires from the
microphone.
SIG+/SIG- = MIC audio
SHLD – MIC shield
SW/SW = MIC key switch
5
Microphone RCA Input
The Microphone RCA input allows a line-level microphone input to be used for
paging.
Connect a line-level microphone signal to the MIC RCA connector using an RCA
cable.
Mic PTT Input
The Phone input is for phone paging.
Connect a POTS appearance phone line to the PHONE connector using an RJ11
cable.
6
The MIC PTT input is for the microphone’s PTT switch.
Wire the MIC PTT wires to this input (polarity independent).
NO
COM
MIC PTT
GND (Audio Com)
The GND (Audio Com) connector is the audio return for the system. Connect a
single 16 AWG conductor from the Global MPI-2 GND (Audio Com) to the Local
MPI-2 GND.
AC Input
Connect the supplied IEC power cord to the AC Input. The unit is rated ate 100-
240VAC.
Using the System
Power LED
The Power LED indicates power to the MPI.
7
Activity
The activity LEDs indicate LON activity. The LEDs will be flickering under normal
activity. LON is the communication protocol for the iNET system.
Page On/Off pushbutton
The page on/off pushbutton is used to toggle the page on and off command.
This is used for testing and troubleshooting purposes. Press the Page On/Off
once to initiate a page and a second time to tun the page off. The Page On LED
will stay on until the page is manually turned off indicating that a page is in
process.
