5 Getting started
5.1 Purpose
This chapter provides instructions on how to get started with the CMi4140. After reading and carefully
following each step of this chapter, your meter connectivity module
should
be mounted and connected to
the LoRaWAN network.
5.2 Product specification
5.3 Mount and start-up the device
5.3.1 Mounting and connection
CMi4140 is mounted in the module slot of a Kamstrup MULTICAL® 403, MULTICAL® 603 or
MULTICAL® 803 heat/cooling meter. Grab the device by the outer edges, gently press it into position and
connect the power connector to the meter power supply.
5.3.2 Connection of antenna
CMi4140 is available in two different versions, with internal PCB antenna (CMi4140Int) and with external
antenna (CMi4140Ext), both are connected using an MCX connector.
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.
5.3.3 Network preparation
For the module to connect to the LoRaWAN network, it needs to be added in the network server. More
specifically, the following device information needs to be registered: Device EUI, Application key and Join
EUI. (If using ABP mode, the following information should be registered instead: Application Session key,
Network Session key and Device address.)
Elvaco strongly recommends using Over-the-air activation (OTAA) to facilitate deployment
and minimize the risk of duplicated keys.
