Installation

Mounting the meter connectivity module

Mount CMi6160 in either a DIEHL SHARKY 775 or a DIEHL SCYLAR 548.

  1. Mount a SIM card (size: Nano) in the SIM card holder.

  2. When the SIM card has been mounted, open the calculator by folding down the side catches.

  3. Lock the module into the appropriate slot (preferable slot 2, see the following picture, mandatory when internal antenna is uses) and carefully connect the pre-formed ribbon cable at both ends.

Connecting the battery

If not already assembled to the meter, see Diehl Metering's mounting instruction for external battery packs. When the battery pack has been mounted properly alongside the meter, connect the power cable from the battery to the power connector on the CMi6160.

Connection of the antenna

Using internal antenna

  1. Place the antenna in the meter housing according to the following image.

  2. Connect the antenna cable to the MCX antenna connector on the module.

    Note

    Make sure to not clamp the antenna cable when closing the lid.

Using external antenna

  1. Make a hole in the rubber gromets/sealing and push the MCX connector through the gromets/sealing. Make sure that the thicker part of the antenna cable is in the gromet/sealing.

  2. Connect the antenna cable to the MCX antenna connector on the module.

Activating the module

Upon delivery, the module is set to passive mode, which means no messages will be transmitted from the module. The module can be activated in one of the following ways:

Via the module push button

  1. Press down the push button of the module for at least five seconds.

  2. Release the button when the green LED lights up.

  3. Wait for up to 10 seconds.

The module indicates start-up by flashing red and green LEDs for one second.

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

Depending on smartphone used, it can be difficult to access the NFC field having the meter closed. For better sensitivity, open the meter and put the phone close to the NFC mark on the module.

Connecting to the network

When activated, the module will attempt to connect to the NB-IoT network. This phase is indicated by the green and red LED lights up for 1 second, followed by short flashes on the green LED until the module has joined the network. When the module succeeds in connecting to the network, the green LED will be lit for 8 seconds, as illustrated in the image below. Upon successful connection, a meter readout will automatically be sent to the receiving system.

If the module fails to join the mobile network, it will perform retries until it succeeds. The time between each attempt will increase for every attempt until it is performed once every day. A new join attempt cycle can be manually started anytime by using the push button to reboot the module or by deactivating and activating the module using the Elvaco OTC App.
