Yes, a rain sensor can be connected with the following connectivity types:

• Digital input
• Analog input
• Modbus communication

No, Modbus-connected devices must be of the same type.

It is possible to add devices that are connected directly to the gateway. That is, analog input and digital input/output.

Note that Modbus-connected devices must use the same connection type. For information on connection types and limits in number of devices, see Compatible Devices.

The voltage requirement differs between the CCD and the digital I/O:

• The CCD runs at 12-16 VDC.
• The digital I/O runs at 24 V.

Thus, at a low voltage, the CCD can communicate with its devices but does not have sufficient power to overcome the relay of the digital I/O.

To use the digital I/O, make sure that the power supply for the CCD is 24 V.

Below RS232/RS485 communication parameters supported:

• Baudrate: 9600, 14400, 19200, 38400, 57600, 115200
• Databits: 7, 8
• Stopbits: 1, 2
• Parity: NONE, EVEN, ODD
• Modbus : 1-247

Information about the maximum number of devices can be found on the Compatible Devices page.

For CCD 401, digital input is active when connected to GND and it is inactive when open.

It indicates that the modem is not responding appropriately to Secure Connect's attempts to communicate with it. Please view the matching Error messages FAQ for additional details.

It is recommended to use the suggested antenna. It is possible to use another antenna under the following conditions:

1. The antenna does not affect the radio frequency (RF) properties.
2. The antenna is the same antenna type as the recommended antenna.
3. The antenna has the same or lower gain than the recommended antenna.
4. The antenna has the same RF characteristics as the recommended antenna.

Yes, the CCD 401 gateway has an internal lithium-ion battery with one cell, 2600 mAh.

The CCD 401 gateway supports four digital inputs. Each digital input can be used either as a normal input or as a pulse counter. The digital inputs have an internal pull-up resistor.

The CCD 401 gateway supports two digital outputs.

For more information about the terminals, see How do I connect the digital outputs on CCD 401?

For more information about the maximum load, see What is the maximum voltage that can be applied to a digital output?

The following connection charts show how to connect the digital outputs on CCD 401.

CCD does not have a SIM card in the slot. It has a built-in embedded subscriber identity module (eSIM) to send data over the Long Term Evolution (LTE) network. If an LTE network is not available, the unit sends data over a 2G or 3G network. The built-in eSIM provides cellular connectivity through a private Access Point Name (APN).

The recommended mode of communication for the unit is cellular connectivity through the built-in eSIM.

The unit can also connect using a custom micro SIM card. When using a custom micro SIM card for the internet connection:

• The custom micro SIM card overrides the built-in eSIM.
• Use the private APN plan of the cellular provider and keep the dataflows isolated from the public internet.

Yes, but this will make digital input and digital output non-functional. Use this way only if your setup does not require them.

Before adding CCD 401 in Secure Connect, examine the following:

1. The device is turned on and the network LED is solid or blinking green.
2. Cloud connection LED is solid or blinking yellow.

The IP/subnet mask for CCD 401 is 10.10.10.2/255.255.255.0

The terminal block is designed for stranded and solid wires with an area between 28 and 20 AWG (0,08 – 0,50 mm2). Stranded cable shall be striped 7 mm and twined for mounting. The orange spring button must be pressed to bottom before inserting the cable in the terminal blocks. The spring button shall be pressed behind the front surface of the terminal. For this, a tool with a small tip must be used.

Yes, it is possible. Look at below diagram to understand the connection requirements:

These requirements apply for the antenna installation:

• The antenna must be kept away from the radio or EMC source.
• The antenna cables must be kept away from other electronics.
• The length of the antenna cables must be as short as possible.
• The antenna cables can run the full length but they must not be bent to avoid interference and crosstalk.

The signal strength and device status can be viewed in the Secure Connect application.

Antenna:

• SMA connector
• Maximum 4 m (13.1 ft) cable
• Torque 0.56 Nm (0.41 lb.ft)

Check the network signal strength.

LED	State	Description
	Solid green	Excellent or good signal strength
	Solid red	Medium or fair signal strength
	Unlit	Poor or no signal

The state of LED must be solid green to avoid the connectivity problems.

LED	State	Connection
	Blink or solid yellow	Yes
	Unlit	No

The connection procedure takes maximum 15 minutes.
The unit must not be disconnected during the connection procedure.

Connect the unit to the internet through Ethernet. With an Ethernet connection, mobile connectivity is not available.

The connection procedure takes maximum 5 minutes.

• If possible, use the recommended secure mode of communication for the unit which is mobile connectivity through the built-in eSIM.
• Configure network access controls and firewall rules to restrict traffic to and from the unit.
• Only enable ports, services, or protocols that are required for the operation of the unit.

1. Check that the power supply of the unit is on.
2. Configure the firewall settings to allow outbound traffic on these ports for the selected network:
   - MQTT 8883
   - HTTPS 443
3. Configure the firewall settings to prohibit inbound traffic.
   The unit initiates all communication and only uses outbound traffic. No inbound remote connections are possible.
4. Check that the router settings align with the following default settings of the unit.
   

   Parameter	Default value
   IP address	10.10.10.2
   Default gateway	10.10.10.1
   Subnet mask	255.255.255.0

   Once the initial connection is set up, then new settings for IP address, default gateway, and subnet mask can be configured through Xylem Vue Secure Connect.
5. Remove the terminal block of the power supply of the unit to turn off the unit.
6. Connect the Ethernet cable to the Ethernet port of the unit.
7. Insert the terminal block of the power supply of the unit to turn on the unit. The unit connects to the internet.
   Do not disconnect the unit from the power supply during the connection procedure.
8. Check the connecton to the cloud service.
   Wait up to 5 minutes for the connection to set up.

The CCD 401 gateway supports two digital outputs. The gateway supports a maximum voltage range of 24 V. The outputs are open collector outputs.

The output device that the digital output controls, for example a relay, must connect to an external power supply and to the digital output.

The outputs have an internal 33 kiloohm pull-up resistor to 24 V. The maximum sink current of the outputs is 100 mA.

Gateway	IP address range	Recommended IP address	Maximum number of connected devices
CCD 401	10.10.10.1–10.10.10.255	10.10.10.10	4 The devices must be of the same type.

Most devices use port 502, which is the standard port for Modbus TCP.

The Modbus server address must be defined for the device to communicate with the gateway and Secure Connect through Modbus TCP. If the device does not have a Modbus server address, it is possible to use 1 as the address.

If the IP address in the device is changed, the device can need a restart before the change applies.

The CCD 401 does not have a Modbus address. The Secure Connect application contains a field to enter a slave address for the devices which uses both an IP address and a slave address as identifiers.

It means that the device is not communicating with the CCD. The communication cable might not be installed correctly, or the settings in the application or the device is not correct (wrong Modbus address or other communication link parameters).

Please see the Alarms FAQs for more information.
