3. The installation and configuration are complete
7 Before field deployment
Before field deployment, make sure that your READy Manager system is prepared for collecting data from encoded meters via
READy MTU by following the steps in this section.
7.1 Import READy MTU from Kamstrup Encryption Key Service
READy MTU is automatically imported into READy Manager if you are logged in with your My Kamstrup account and the Import
new devices checkbox is ticked.
If not logged in, you can import READy MTUs directly from Kamstrup Encryption Key Service found in My Kamstrup.
Click the Import devices button on the start-up page of READy Manager.
More information can be found in the READy Manager guide under Automatically importing information for new devices or
Manually importing information for new devices.
7.2 Import non-Kamstrup meters and customer information in READy Manager
Kamstrup recommends that you import the ID/serial number that is sent on the encoded output as the meter
serial number in READy Manager. If not, you are required to overwrite the serial number of the encoded output
with the serial number imported in READy Manager for your specific device.
Import non-Kamstrup meters and customer information in READy Manager by selecting Import customers on the start-up
page of READy Manager.
More information on CIS import can be found in the READy Manager guide under Automatically importing customer data or
Manually importing customer data.

READy MTU
7.3 Create a group of non-Kamstrup meters for READy MTU installation
It is recommended to create a group of non-Kamstrup meters that will be retrofitted with READy MTU that can be synced with
READy App.
Create a group:
1. Select the Meters view in READy Manager.
2. Select New group. Name the group.
3. Select the meters that are to be part of the group and add the meters to the group.
Find more information in the READy Manager guide under Organizing meters in reading groups.
7.4 MTU modes and LED blinking scheme
7.4.1 MTU modes
7.4.1.1 Transport mode
When you receive READy MTU, the device is in transport mode. In transport mode, the radio is deactivated. The magnet sensor
for activating the MTU is active.
By influencing the magnet sensor for 3 seconds, the LED on the front of READy MTU turns on. The MTU checks if a meter is
connected on the encoded interface before turning on the radio. If no meter is connected, READy MTU remains in transport
mode.
Remember to enable transport mode when decommissioning READy MTU. See section 9.6 Decommissioning.
7.4.1.2 Installation mode
After activation, READy MTU starts up in installation mode. The LED turns on and a connection beacon is sent out every 4
seconds.
Installation mode is active for 5 minutes after activation.
After the installation mode period has ended, READy MTU enters normal mode.
When operating in normal mode, installation mode can be triggered by holding the magnet to the front of READy MTU. This will
also reactivate the LED.
7.4.1.3 Operation mode
In operation mode, READy MTU can at all times be accessed via READy App. A connection beacon is sent every 30 seconds
during normal operation. The LED is not active in normal mode.
7.4.2 LED blinking scheme
1 time every 5 seconds Everything is OK.
READy MTU is reading the encoded output and sending data
via AMI.
3 times every 5 seconds Something is wrong.
READy MTU is not reading the encoded output or sending
data via AMI.

8.1 Installation
READy MTU is intended to be installed in vertical position indoors and outdoors in residential, commercial, and industrial
environments. The device is intended to be installed either at ground level, above ground on a wall, or in pits (flooded
environment, underground). As READy MTU is IP68 rated, the device is resistant to harmful dust and can be submerged.

8.2 Configuration of READy MTU
Required:
• Android device
• READy App (synchronized with READy Manager)
• READy Converter
• Magnet
8.3 Default or preconfigured
If your READy MTU has been ordered preconfigured, please follow section 8.3.1 Configuration of preconfigured MTU.
If your READy MTU has been ordered default configured, please follow section 8.3.2 Configuration of default configured MTU.
If in doubt, follow 8.3.2 Configuration of default configured MTU.
8.3.1 Configuration of preconfigured MTU
A preconfigured MTU requires that the device serial number imported in READy Manager equals the device ID
read on the encoded output.
Complete all cable connections before activating the device using the magnet sensor.
If the device serial number imported in READy Manager does not equal the ID read by the MTU on the encoded output, please
follow the installation and configuration instructions for default configured MTU in section 8.3.2 Configuration of default
configured MTU.

Installation & operation guide
Kamstrup A/S • 55122662_C1_US_06.2020 15
READy MTU
1. The LED starts blinking 3 times every 5 seconds.
NOTE: Finish all cable connections before activating
READy MTU.
2. When the LED blinks 1 time every 5 seconds, everything
is OK.
READy MTU is reading the encoded output and sending
data via AMI.
The LED automatically stops blinking after 5 minutes. No further configuration is needed.
The configuration of a preconfigured MTU can at all times be read and changed by following the steps in section 9.5
Reconfiguration.
8.3.2 Configuration of default configured MTU
A default configured MTU requires configuration using READy App.
The reading on the encoded output must match the imported meter ID/serial number in READy Manager. If the
IDs do not match, you can overwrite the encoded output reading to ensure data flows to the correct meter.
1. Sync READy Manager and READy App before
proceeding to step 2.
2. Activate READy MTU by pointing a magnet at the
designated spot.
3. The LED starts blinking.
