1.3 ClimaCheck Gateway NX400 internal application version and PA-ID

Each Gateway unit has a unique id number to identify it on the ClimaCheck Online server, this

number is set by ClimaCheck and can be seen in the display, on the second row, after the unit has

booted up as “ID=XXXXXX”.

The internal application version can be seen in the display on the same row as the PA-ID. Contact

ClimaCheck support for information on the latest version.

2Communication

The Gateway has LAN, Wifi, modem for Mobile connections and USB to communicate with the

ClimaCheck server or a local PC. It has Modbus TCP and Modbus RTU and can be configured both

as Server/Slave and Client/Master.

2.1 Ports

The Gateway uses the following ports when communicating with the ClimaCheck Online server:

•UDP port 2049 to online.climacheck.com: Send data as a text string (ID, Timestamp,

data1, data2, ….) to ClimaCheck online

•TCP port 80 to integration.climacheck.com: Fetch configuration and analysed values

•TCP port 5001 to online.climacheck.com: Firmware and application updates and

troubleshooting.

2.2 SMS Commands

SMS commands can be used to control the ClimaCheck Gateway. In Online Mode the modem in

the unit is always active, except when “No Network” is selected. In PC Mode the modem can be

activated and deactivated from the Network Setup menu, see section 3.13. When the modem is

active SMS commands are executed regardless of which network interface is used to communicate

(GPRS, LAN, WiFi) as long as an active sim card is inserted.

The SMS commands are listed and described in Table 2 below.

Table 2 SMS Commands

Command

CFG

Fetch configuration from ClimaCheck Online server

CMD

Check for new commands on ClimaCheck Online server

RST

Reboot unit

APN new_apn

Changes the APN settings to “new_apn”. If APN internet.com is sent it will

change APN to internet.com

NET GPRS

Changes selected network interface to mobile/GPRS

NET LAN

Changes selected network interface to LAN

NET WLAN

Changes selected network interface WLAN / Wifi

There should be One space between the command (APN or NET) and the parameter (new_APN,

LAN, WLAN, GPRS).

The unit will respond with an SMS and then execute the command.

If selected network interface is changed with SMS commands make sure correct configuration

(APN, SSID´s or IP addresses) is set for the new network. To change network configuration like

APN, SSID’s or IP addresses for GPRS, LAN or WLAN use the PA Pro III Configurator, see section 4.

ClimaCheck Gateway NX400 Hardware Manual –2020-03-26 Page 10 of 41

2.3 Connection Mode

The Gateway has two main connection modes, Online Mode and PC Mode. PC Mode is the default

setting when logging data to the PC Software with ClimaCheck Onsite and Online Mode is default

setting in permanent ClimaCheck Online installations.

When booting up the Gateway asks “Connect to PC ?”, press No to enter Online Mode or Yes to

enter PC Mode. For Online mode the preferred network interface to connect to the ClimaCheck

Online server can be changed between LAN, Wifi and GPRS, see section 3.11.

In PC Mode the unit will ask for “Connection type” to select how to connect the computer to the

NX400. First option is USB Cable / WiFi and second option is Direct ethernet cable between

computer and NX400, see Figure 4 and section 2.4 for more information on how to connect a PC.

If no selection is made the unit activates Online Mode or PC Mode (USB Cable / WiFi) automatically

depending on the default setting. This default setting can be changed with the PAPro III

configurator, see section 4.12. Selected connection mode is indicated on the bottom row of the

display.

Figure 4, Connection Mode

The configuration of the network interfaces in the different connection modes can be seen in Table

3 below. USB connectivity is always available regardless of connection mode.

Note, do not connect the Gateway to a network (LAN) via ethernet cable while in PC

Mode (Eth. Cable), the unit’s DHCP server is active which may cause IP conflicts on the

network. Use Online Mode or PC Mode (USB/WiFi) instead if the unit is connected to a

network.
