Elvaco CMi4140 Quick Manual

Quick manual
Introduction
CMi4140 is a meter connectivity module mounted inside a
Kamstrup MULTICAL 403/603/803 heating/cooling meter to
deliver meter data to a receiving server via a LoRaWAN®
network. The module is energy-efficient and offers 11 years
of battery lifetime with EcoMode enabled. It can be retro-
fitted into deployed meters and is ideal for applications
where long range is required. CMi4140 is easily configured
through Elvaco OTC mobile app, or via downlink commands.
With CMi4140, Elvaco offers a meter connectivity module
designed for customers that require a user-friendly and cost-
effective solution.

Parts overview
1. Pulse inputs In A and In B (allowing to connect adjacent
pulse meters)
2. Power connector
3. MCX antenna connector
NOTE
The MCX antenna connector is used for connecting either an inter-
nal or an external antenna.
Mounting the product
CMi4140 can be used in either a Kamstrup MULTICAL® 403,
MULTICAL® 603, or a MULTICAL® 803 heat/cooling meter.
If the module is not mounted in the meter upon delivery, it is
easily inserted and installed:
1. Grab the device by the outer edges.
2. Gently press it into position in the module slot.
3. Connect the power connector to the meter power supply.
CAUTION
This is an electrostatic-sensitive product. Observe the necessary
ESD protective measures when installing the product.
Connection of the LoRaWAN® antenna
CMi4140 has an option for using either an internal or an
external LoRaWAN® antenna. Since both antennas are using
the MCX connector, they are interchangeable.
1. Connect the internal or external or antenna with MCX
connector to the module in the meter.
2. Route the antenna cable (if using an external antenna)
3. Push the connector gently into the socket on the module.
CAUTION
If using an external antenna, make sure to mount it at least 0.5
meters away from the meter in order not to cause interference.
Activating the module
NOTE
Before activating the module, and trying to join a LoRaWAN®
network, make sure the LoRaWAN® network server of use is
prepared with necessary device and security related information.
Security keys for Elvaco devices can be accessed in Elvaco EVO,

Upon delivery, the module is set to inactive mode, which
means no messages will be transmitted from the module be-
fore being activated. The module can be activated either via
the buttons on the meter, or via the Elvaco OTC App:
Module activation via meter buttons
• On MULTICAL® 403, press and hold both buttons on the
front of the meter until "CALL" is displayed.
• On MULTICAL® 603 and MULTICAL® 803, press down the
two arrow buttons on the front of the meter until "CALL" is
displayed.
Module activation via Elvaco OTC App
1. Open Elvaco OTC app (available for Android and iOS).
2. Scan the module (make sure NFC is activated on the
phone).
3. Go to Apply mode.
4. Set the power mode to Active.
5. Select Apply settings.
6. Scan the module to apply new settings.
To verify that the module has been activated, go to
Inspect, scan the module, and make sure that power
mode is set to Active.
TIP
• If the module is mounted inside a MULTICAL® 403, the NFC
field is easiest accessible if placing your phone in the middle of
the higher part of the back.
• MULTICAL® 603 has two module slots. If mounted in the left
module slot, the NFC field is easiest accessible if placing your
phone in the middle of the higher part of the back. If the module
is mounted in the right module slot, place your phone to the right
of the higher part of the back.
• If the module is mounted in MULTICAL® 803, the meter needs
to be open to access the NFC field. Place your phone close to
the CMi4140 when making the NFC scan.
Joining the LoRaWAN® network
When activated, the module will attempt to join the LoRa-
WAN® network. If the module fails to join the LoRaWAN®
network it will perform retries until it succeeds. The time be-
tween each attempt will increase for every attempt until it's
performed once every day. A new join attempt cycle can be
manually started anytime by deactivating and activating the
module using the Elvaco OTC App.
When the module has joined the LoRaWAN® network, me-
ter data will initially be transmitted from the module every
minute (regardless of transmit interval settings) in order to
set the right data rate. After three minutes of calibration, the
module will start to deliver meter data using its configured
settings. By using the Elvaco OTC App, you can easily verify
that the module is successfully communicating with the meter
("Meter communication") and is connected to the LoRaWAN®
network ("Network joined").
LoRaWAN® network end-device activation
Before being able to transmit data over a LoRaWAN® net-
work, the module must be personalized and activated. This
