3 Device descripon
3.1 Field of applicaon
The CU-XE communicaon module can be installed in and uninstalled from the following
Landis+Gyr meters without opening the calibraon seal:
• E650 ZxD300/400xT industrial and commercial meters
• E850 ZxQ high-precision meters
• S650 SxA300/400xT and SMA500 Smart Grid Terminals
• E65C CU-ADPx adapters
3.2 Characteriscs
The CU-XE communicaon module contains two independent Ethernet interfaces, one RS-232
serial interface and one RS-422/RS-485 serial interface . The device also contains a powerful
applicaon processor for networking, security and data processing funconalies.
3.3 Type designaon
The type designaon of the CU-XE communicaon module is added to that of the meter (see
meter User Manual), but is not shown on the main faceplate of the meter. The type
designaon is inscribed on the case of the communicaon module and can be seen through

The CU-XE communicaon module is available in the following versions:
Type Ethernet RS-485/RS-422 RS-232
E65C CU-XE ● ● ●
3.4 Funcons
The Funconal Descripon of the CU-XE communicaon module is provided separately. The
main funcons are briey summarised below.
3.4.1 Ethernet interfaces
The communicaon module oers two Ethernet interfaces supporng 100BASE-TX and
10BASE-TX. Depending on the Ethernet interface used, the communicaon module oers
various services. The two Ethernet interfaces can be congured independently. This
conguraon is dened during the ordering process and can be changed during operaon.
3.4.2 RS-485/RS-422 interface
The RS-485/RS-422 interface is a serial, bi-direconal, dierenal interface. The interface
includes user congurable bias and terminaon resistors. A typical applicaon is to create a
mul-drop bus, where mulple devices can share the communicaon channel. For example, up
to 31 E650 meters can be connected to the RS-485 bus congured as the bus master, and they
can be read remotely using the Ethernet interface.
To congure the RS-485/RS-422 operaonal mode as well as the bias and terminaon resistors,
DIP switches on the backside of the PCB can be used. The DIP switches are accessible only
when the CM is removed from the meter.

5 Installaon/uninstallaon
5.1 Installaon in a meter
Warning
No voltage to the meter during installaon
In order to avoid hazardous electric shocks, make sure that there is no voltage applied
to the meter when installing the communicaon module. Contact with live parts is
dangerous to life. Disconnect the meter from the power supply as described in the
meter User Manual.
Note
Excessive number of power failures reduces life of product
The CM writes to its internal ash memory every me there is a power failure. This
type of memory has a life expectancy of approximately 100,000 write cycles. This is
not a guaranteed value. During a lifespan of 15 years this would amount to
approximately 15 power failures per day. Exceeding this number may shorten the
useful life of the product.
Note
E65C CU-XE communicaon modules can be used in E650 (from Series 3 FW version
B30 upwards), S650 and E850 electricity meters or in CU-ADPx adapters
The CM is designed to be operable with meters menoned above. The CM should not
be operated with other devices even if it can be inserted to the device. Compability
with other devices cannot be guaranteed.
Install the communicaon module in a meter as follows:
1. Make sure that no voltage is applied to the meter.
2. Remove the ulity seals on the front door and terminal block cover.
3. Open the front door and remove the terminal block cover.

8. Change the inial password that was specied prior to order conrmaon. See secon My
sengs / password on page 52.
5.2 Connecng the communicaon module
5.2.1 Connecng the RS-485 interface
1. Insert the connecng cable with the RJ12 connector to the socket labelled RS-485/RS-422
in the communicaon module unl the connector engages.
2. Connect the other end of the cable to the nearest unit of the RS-485 mulple connecon.
The RS-485 interface of the CU-XE is provided with one RJ12 socket. Extensions for the
RS-485 must therefore be formed with an external splier.
Figure 7: Connecng mulple communicaon modules
Cauon
External wiring of RS-485
In order to funcon correctly, all 3 wires (data a, data b and common GND) must be
connected. RS-485 operaon with only 2 wires (without common GND) is forbidden
as the RS-485 interface may not funcon correctly or may even get damaged.
5.2.2 Resealing the meter
Aer all connecons have been made and the device is properly congured, you can replace
the covers and reseal the meter with a ulity seal.
5.3 Commissioning and funconal check
The CU-XE communicaon module should be taken into operaon as follows (see also secon
Operaon on page 19 for a detailed descripon of LED states):
1. Aer switching on the mains voltage, a red boot LED is blinking. When the communicaon
module is ready for operaon, the LED switches to green. When the Ethernet connecon
is made, the running LED is illuminated.
2. A remote readout of meter data via Ethernet should be performed as a funconal check if
the CU has been appropriately congured.
3. If a mulple connecon to further devices is used, check that they are working as
expected.

6 Operaon
The CU-XE communicaon module features four LEDs to display operaonal status
informaon. These LEDs are visible through the transparent plasc housing on the right side of
the faceplate. Refer to LED status descripons on page 14 for more informaon.
Note
Aer conguraon change the power cannot be cut o for 10 seconds, otherwise the
CM can be damaged.
6.1 Accessing the Web UI
To ease installaon and maintenance, the communicaon module features a Web UI. The Web
UI is accessible on the ethernet interface ETH1 and/or ETH0 and modem, depending on the
conguraon, using a standard, up-to-date web browser (e.g. Chrome, Firefox or Edge).
Note
The Web UI is not accessible over the opcal port nor the RS485 interface
The Web UI is only accessible over ethernet interfaces.
The ethernet interfce ETH0 and ETH1 can be congured in mulple ways, refer to Ethernet
ports on page 32 for more informaon.
6.1.1 Management port on ETH1
If the management port is enabled, it is accessible on the ETH1 interface at IP address
172.16.0.1 or at hps://hostname.landis. The management port features a DHCP and DNS
server. Establishing the connecon is easier if the ethernet interface of the PC is set in DHCP
mode. See the example below from Windows 10 sengs (click Start > Sengs > Network &
Internet > Ethernet > Change adapter opons).
