3.2 R1 Port Small DIP Switches
Gently remove the FieldServer enclosure to access the small DIP switches for the R1 Port.
•If more than one RS-485 device is connected to the network, then the field bias resistor switch
needs to be enabled to ensure proper communication. See Figure 5 for the orientation of switch
positions referenced below.
oThe default factory setting is OFF (switch position = right side)
oTo enable biasing, turn the bias switch ON (switch position = left side)
NOTE: Biasing only needs to be enabled on one device. The FieldServer has 510 ohm resistors
that are used to set the biasing.
•If the FieldServer is the last device on the trunk, then the end of line (EOL) termination switch needs
to be enabled. See Figure 5 for the orientation of switch positions referenced below.
oThe default factory setting is OFF (switch position = right side)
oTo enable the EOL termination, turn the EOL switch ON (switch position = left side)

Operation
EZ Gateway Start-up Guide 11
4Operation
4.1 Power Up the Device
Apply power to the device. Ensure that the power supply used complies with the specifications provided.
Ensure that the cable is grounded using the “Frame GND” terminal. The EZ Gateway is factory set for
9-30V DC or 12-24V AC.
NOTE: A KNX compatible power supply is required on the KNX network.
4.2 Connect the PC to the EZ Gateway Over the Ethernet Port
•Connect an Ethernet cable between the PC and EZ Gateway or connect the EZ Gateway and the
PC to the switch using a straight Cat-5 cable.
•The Default IP Address of the EZ Gateway is 192.168.2.101, Subnet Mask is 255.255.255.0.

4.3 Connecting to the EZ Gateway
4.3.1 Using the FieldServer Toolbox to Discover and Connect to the EZ Gateway
•Install the Toolbox application from the USB drive or download it from the MSA Safety website.
•Use the FS Toolbox application to find the EZ Gateway and launch the FS-GUI.
NOTE: If the connect button is greyed out, the EZ Gateway’s IP Address must be set to be on the
same network as the PC. (Section 4.3.2)
4.3.2 Using a Web Browser to Connect to the EZ Gateway
•Open a web browser and connect to the EZ Gateway’s default IP Address. The default IP Address
of the FieldServer is 192.168.2.101, Subnet Mask is 255.255.255.0.
•If the PC and the EZ Gateway are on different IP networks, assign a static IP Address to the PC
on the 192.168.2.X network.

5Setup Web Server Security
5.1 Login to the FieldServer
The first time the FieldServer GUI is opened in a browser, the IP Address for the gateway will appear as
untrusted. This will cause the following pop-up windows to appear.
•When the Web Server Security Unconfigured window appears, read the text and choose whether
to move forward with HTTPS or HTTP.
•When the warning that “Your connection is not private” appears, click the advanced button on the
bottom left corner of the screen.

•Additional text will expand below the warning, click the underlined text to go to the IP Address. In
the Figure 10 example this text is “Proceed to 10.40.50.94 (unsafe)”.
•When the login screen appears, put in the Username (default is “admin”) and the Password (found
on the label of the FieldServer).
NOTE: There is also a QR code in the top right corner of the FieldServer label that shows the
default unique password when scanned.
NOTE: A user has 5 attempts to login then there will be a 10-minute lockout. There is no timeout
on the FieldServer to enter a password.
NOTE: To create individual user logins, go to 8.2.
