3Installation
All local and national electrical safety codes (NESC®) must be followed when installing the MP2. If there
is any contradiction in this manual and those standards, then the installer must follow the local and
national codes. Use copper conductors only. The TELSEC®MP2 is designed for mounting on a wall or
within a rack. Rack mounting is accomplished by using the optional (not included) mounting ears for a
19 or 23” rack. Contact your Quest representative to order the Rack Mounting Ear kit (PN 150989).
3.1 Mounting the MP2
Install the MP2 in the desired location using #8 hardware to connect the two mounting tabs to the wall.

Figure 1 - TELSEC®MP2 Dimensions
3.2 Powering and Grounding
3.2.1 Powering the MP2
Follow all national and local electrical codes when powering the MP2. Quest recommends a minimum
of 18AWG conductor for powering. The TELSEC®MP2 will operate from 18-65 VDC power (50 mA max at
48 VDC). The power input is isolated from the rest of the system and will work on either a positive or
negative DC system. The MP2 supports power from a dual (A & B) feed DC power system to provide
redundancy in case one of the feeds is lost. Connect the power source A and B (optional) to the MP2
observing the polarity markings on the enclosure. Quest recommends fusing each power source at 1 A.
Reverse polarity will not damage the unit, but it will not operate until corrected. It is recommended that
all input wiring be completed with no power to the system. Turn on power once all wiring is verified.
3.2.2 Removing the Battery Insulator
The MP2 is shipped with an insulator to keep the battery disengaged from the system. Remove the
insulator once the unit is permanently powered, by pulling the tab in front of the unit. The system uses
the battery to save the system time and input time status.

Rev 1. 1 05/08/19 - 4 - TELSEC©MP2 User Guide
3.2.3 Grounding the MP2
There is a ground post on the left and right side of the chassis. Place a ground wire using a minimum 12
AWG conductor from the Electrical panel ground bus (or other approved grounding point) to the ground
terminal on the MP2. Follow national and local codes and practices for properly grounding the system.
3.3 Connecting the Ethernet
Use a standard Cat5 Ethernet cable to connect the MP2 to the local switch or hub. Configure the switch
port to auto speed detect and auto negotiation. A green LED link light on the ethernet jack will be
illuminated when a physical link has been established. The amber LED on the ethernet jack will be
illuminated when the connection is 100Mb and off if the connection is 10Mb.
3.4 Wiring inputs
Wire each input to be used between the input terminal (1-32) and a common terminal (C). There is a
common terminal available for every two inputs available for termination. The MP2 does not provide
power for sensor operation thus any device requiring power will need an external power source to
operate properly. Refer to the silkscreen on the enclosure for location of each input and common
terminal. The inputs will support any sensor that is a 10k Type III thermistor: 0-6 VDC or 0-20 mA analog
sensors. In addition, the system accepts dry contact closures or wet contact closures up to 65 VDC.
3.4.1 Thermistors
Thermistors are resistive devices and do not have polarity. Connect one lead to the input terminal of
the desired input and the second lead to a common terminal. Quest recommends using shielded and
stranded cable for all analog sensors. Connect the shield of the cable to chassis ground on the MP2. Cut
the drain wire and isolate the shield at the sensor end of the cable.

3.4.2 Voltage Sensors
The TELSEC®MP2 can read and scale any linear voltage input from 0 to 6 VDC. Sensors requiring power
must be externally powered. Contact Quest for the Input Scaling spread sheet to determine the correct
number for the Low and High Custom scale factors.

The TELSEC®MP2 can read and scale any linear current input from 0 to 20 mA. An external 249-ohm
resistor (recommend 1% tolerance) is required to convert the signal to voltage and will require an
external voltage source to power the sensor. Contact Quest for the Input Scaling spread sheet to
determine the correct number for the Low and High Custom scale factors.

3.4.4 Contact Closures
The TELSEC®MP2 supports dry contact closures or wet contacts up to 65 VDC. A wet contact is an input
where there is an external voltage present. A dry contact has no voltage present and the MP2 provides

Rev 1. 1 05/08/19 - 6 - TELSEC©MP2 User Guide
the sensing voltage. The detection point for determining ON/OFF status is greater than 2.8 VDC and less
than 0.8 VDC. There is no transition when the voltage is between these two values. Both wet and dry
input types are connected between the input terminal and a common terminal. For Wet inputs the
voltage must be between 0VDC and up to +65VDC. Negative voltages are not supported. Make sure to
define the input properly for “Wet” or “Dry” contact closures (see section 9.1) for proper operation.
Monitor Switch
Figure 5 - Wiring Contact Closures
3.5 Wiring for Modbus
The MP2 has two serial ports labeled COM 1 and COM 2. Either port (or both) can be used to poll
Modbus RTU devices. The MP2 acts as the master and can support up to 512 registers per serial port
(1024 total).
1. Connect no more than 32 Modbus devices per Modbus serial port
2. The maximum overall Modbus cable network length is 3,000 feet.
3. For normal applications, use Belden Cable #8102 or equivalent. This cable has two twisted pairs
and a separate foil shield. For applications requiring a more mechanically robust cable, use
Belden Cable #9842. This cable has two twisted pairs, a separate shield and a separate braided
shield.
4. Use one of the twisted pairs for the D0 (-) and D1 (+) connections and use the second twisted
pair for the C/Common connections. The cable shields must never be used for the C/Common
connections.
5. All the D0 (-) pins from every Modbus device on the network must be connected together. The
same is true with the D1 (+) pins, and the C/Common pins.
6. Connect the Modbus devices together in a daisy-chain configuration only. In this configuration,
the cable from the first Modbus device connector goes directly to the connector of the second
Modbus device, then from that connector directly to the connector of the third Modbus devices,
and so on. No star, ring or tree cabling network configurations, or additional cable stubs are
allowed. See Figure 7 below.
7. Connect all the cable shields together so that they form one continuous connection from one
end of the Modbus cable network to the other. If a braided shield is also included in the cable,
then connect all of them together as well. If there is a mix of braided and non-braided shields in
the cabling network, then connect the braided shields together and then to the foil shields of
the nearest non-braided cable. At no time are any shields to be left floating.

Rev 1. 1 05/08/19 - 7 - TELSEC©MP2 User Guide
8. At the MP2, connect the cable shield to the protective (protected) earth ground. The cable
shields must not be connected to earth ground anywhere else in the cabling network except at
this point.
3.6 Line Termination
1. At each end of the Modbus cable network daisy-chain, there must be an end of line termination
resistor. Connect a 1/2W 120-ohm resistor across the D0 and D1 conductors of the end devices.
See Figure 7 below.
2. If the MP2 is at one end of the Modbus cable network, then use the built in End of Line resistor.
Remove the cover of the MP2 and locate DIP switch in the front right corner of the board. SW3
is for COM1 and SW4 is for COM2. Press switch number 2 down (middle switch) to enable the
end of line terminating resistor. If the MP2 is not the last device on the Modbus cable network,
then move switch 2 to the up position. See Figure 6 and Figure 7 below. No more than two line
terminations are allowed per Modbus cable network.
3.7 Line Polarization
When there is no data activity on an RS-485 balanced pair, the lines are not driven and, thus susceptible
to external noise or interference. To insure the receiver line stays in a constant state, when no data
signal is present, some devices need to bias the network. Polarization of the pair must be implemented
at one location for the entire Serial Bus. Generally, this point is at the master device such as the MP2.
Other devices must not implement any polarization. Refer to the manual of the device you are
monitoring to determine if line biasing is required. Remove the cover of the MP2 and locate DIP switch
in the front right corner of the board. Switches 1 &3 on dipswitch SW3 is for COM1 and Switches 1 & 3
on dipswitch SW4 are for COM2. Line polarization is enabled when both switches are in the down
position and disabled when in the up position. Switches 1&3 must be in the same position on the
dipswitch. Refer to Figure 6.

3.8 Wiring Outputs
There are four form C relays available for control of external devices based upon alarm conditions or
time schedules. Place wire between the common and normally open or normally closed terminals for
each output on the MP2. The relays are designed for Class 2 wiring and are rated for a maximum of 1
amp at 24VAC or 30VDC, 0.3 A @ 60VDC.
Figure 8 - Wiring Outputs
4Local Operation
4.1 Power LED
Once the TELSEC®MP2 is installed, powered, and connected with an Ethernet connection, the system
will start operation based on the program controlling the unit. Under normal operation the green
Power LED will flash at one second intervals to indicate the system is operating properly. Occasionally
there may be a pause in this operation if the system is saving data to flash memory. If the LED is off for
longer than one minute, then check the power connection and cycle power to the unit. If the LED is
constantly on longer than a minute, then cycle power to the system to see if it goes back to normal
operation of flashing the LED.
4.2 Alarm LED
The red alarm LED will be illuminated when any of the alarm points are in alarm. This LED does not
provide notification of the state of the control relays since an alarm point may be in alarm, but not
associated with an output. If this LED is illuminated, then log into the web server on the MP2 and
review the active alarm log on the home page.
4.3 Relay Outputs
Relay outputs are programmable for normally energized or de-energized condition. The normally
open/normally closed terminations on the board refer to when the output is de-energized. There are
four outputs that may be associated with an alarm severity or a time schedule. Outputs that are

Rev 1. 1 05/08/19 - 10 - TELSEC©MP2 User Guide
associated to an alarm severity will be “active” when the alarms are present and will deactivate when
either all alarms with the associated severity have cleared or if the acknowledge function is
used. Outputs associated with a time schedule will be “active” when the schedule is on and de-
activated when the schedule is off. Outputs can be bypassed indefinitely or for a period of time
remotely via the built-in web server or by SNMP SET commands.
4.4 Restoring to Factory Defaults
The TELSEC®MP2 has a small access hole on the right side for the cold start switch. Holding this switch
in for approximately 15 seconds during a power up (cycle power off then back on) will cause the system
to erase all programmed settings and go back to the factory defaults. During the Cold Start process, you
will see both the power LED and Alarm LED flash simultaneously every second. After a few seconds, the
alarm (red)LED will be illuminated solidly. Release the cold start switch once the alarm LED is on solid.
5Communicating with the MP2
Connect a standard Ethernet cable between the TELSEC®MP2 and your local Ethernet switch or router.
You can also direct connect to the system with your PC using a crossover Ethernet cable and setting a
static IP address on your PC. The MP2 has a default IP address of 192.168.1.31. Use this address to log
into the unit and then change the IP address to a new permanent setting.
5.1 Connecting to the System
The built-in web server uses a username and password combination to authenticate a user and allow
access. No information will be shown without proper authorization. The default setting uses HTTP
protocol with a username of Admin and password of admin. The username and password are case
sensitive so make sure your caps lock key is turned off. The default password along with the five
available User level passwords can be change once you log in and go to the Settings/User Administration
web page. Keep track of your password because there is no way to access the system without a valid
password. The system will have to be cold started to return to default settings if the password is
unknown.

5.2.1 The Home Page
After you log in with your username and password, the MP2 will display the Home page. This page can
also be displayed if you click on the home icon on the menu ribbon. The home page will show the status
of the outputs and any Active Alarm condition. Outputs have an acknowledge button to allow the user
the ability to return the output to the inactive state. See Figure 11.
Figure 11 - The TELSEC®MP2 Home Page
6System Status
Hovering your mouse pointer on the Status option will provide the choices of Input Status, Modbus
status (if defined), Output Status and Log Data. This section of the manual will review each one of these
options and the available functions.

Rev 1. 1 05/08/19 - 12 - TELSEC©MP2 User Guide
6.1 Input Status
The input status page will show the current value of the universal inputs currently programmed in the
system. The status page groups the inputs based on their definition, into either digital inputs or analog
inputs. The display will show the digital inputs first followed by the analog points. Click on the expand
window icon to display the points.
6.1.1 Digital Inputs
Digital inputs will show the input number followed by the defined name of the point and the current
value. The page will show the ACCUMULATED ON which represents the entire time the input has been
active (ON), this timer can be cleared. The INTERVAL ON timer shows how long this input has been
active this time, when the input clears (OFF) this value will be held. When the input re-activates, this
timer will clear to zero and start counting. The INTERVAL OFF timer reacts similarly to the ON timer but
only counts when the input is off or inactive. The EVENT counter counts one for each change in state of
the input, on is one, off is two, next on is three and so on. The EVENT TIMER begins counting from the
time the input is programmed or from the time the input was last cleared.
The system will keep track of the number of alarms that are active for the input and display that as a
hyper link. Clicking on the link will bring up a window with a table of active alarms for the point.
The Clear Timer column will be present if you have program level or above access for your password.
Clicking on the clear button will clear all the timers for that input. Alternatively, you can clear all input
timers under Settings/Advanced/Clear Input Timers.
Figure 12 - Digital Input Status

Rev 1. 1 05/08/19 - 13 - TELSEC©MP2 User Guide
6.1.2 Analog Inputs
Analog input status will show the input number, the programmed name for the point and the current
value of the input in the defined engineering units. The related alarms column will indicate the number
of active alarms currently present that reference the input. A number greater than 0 will be a hyperlink
that will bring up a window showing a table of active alarms for the point.
Figure 13 - Analog Input Status
6.2 Modbus Status
The MP2 supports two serial ports that both can be configured as Modbus networks. The MP2 acts as a
master which polls the slave devices. The Status menu will show Modbus (port #) where # equals the
physical port being used for Modbus. If both ports are used for Modbus, then there will be two entries
on the menu. Note Modbus will not show as a status option unless the ports are defined for Modbus.
Selecting the Modbus port status will display as status screen of available Modbus points. The points
will be grouped based upon the device they are associated with and the name of the device will be
displayed in the header for each window. Clicking on the expand window icon will display the points for
each device. The points will be listed with their defined name, the current value based on the point
definition and a column showing any related alarms. Related alarms are Alarm Points that reference the
Modbus point and are in an active alarm condition. Clicking on the related alarms number will display a
popup window with a listing of the active alarms.

Rev 1. 1 05/08/19 - 14 - TELSEC©MP2 User Guide
Figure 14 - Modus Input Status
Modbus points that are writable, will be displayed with a write icon . Clicking on this icon will bring
up a window to allow the user to change the value. Enter the value in the converted engineering units
that are being displayed. The MP2 will use the point definition to determine the correct value to be sent
to the device. Note: the actual ability to change a value is dependent on the device being monitored.
Even though the MP2 attempts to write the data, the device may reject the change.
6.3 Output Status
The output status page shows the current status of the four digital outputs. Each output will be shown
with the defined name, Action which is either automatic (AUTO) or BYPASSED if a user has bypassed the
output (Settings/Bypass). The state field shows whether the point is Active or Inactive based upon the
user defined program. The last function is the ability to Acknowledge the current active state which will
cause the output to go to an inactive state until the next condition causing an Active state occurs.

6.4 Log Data
The MP2 will plot a graph of up to four points at a time. The page controls will allow the user to select
from Analog Inputs, Digital Inputs Modbus and Digital Outputs. Any combination of point types can be
charted at one time. Select the point to be graphed and then select the date range for the data. If no
date range is specified, then the system will display the most recent data for the points when clicking on
the Regenerate Graph button.
Figure 16 - Select Data Point to be Graphed
The system will display the graph with a default view of the last 24 hours. Use the page buttons and
zoom in and out icons to view the data in your web browser. The MP2 will display a Download to CSV
button which will download the data in a CSV file for viewing in another program. Note the download
will be the most current 4095 entries per point when no time range was selected. If a large time range
was selected, then the system will return the last 4095 entries per point for the range.
