4.2 DIP Switch Settings

4.2.1 Bias Resistors

To enable Bias Resistors, move both the BIAS- and BIAS+ dip switches to the right in the
orientation shown in Figure 3.

The EZ Gateway bias resistors are used to keep the RS-485 bus to a known state, when there is no
transmission on the line (bus is idling), to help prevent false bits of data from being detected. The bias
resistors typically pull one line high and the other low - far away from the decision point of the logic.

The bias resistor is 510 ohms which is in line with the BACnet spec. It should only be enabled at one
point on the bus (for example, on the field port were there are very weak bias resistors of 100k). Since
there are no jumpers, many EZ Gateways can be put on the network without running into the bias resistor
limit which is < 500 ohms.

NOTE: See www.ni.com/support/serial/resinfo.htm for additional pictures and notes.
NOTE: The R1 and R2 DIP Switches apply settings to the respective serial port.
NOTE: If the gateway is already powered on, DIP switch settings will not take effect unless the

unit is power cycled.

4.2.2 Termination Resistor

If the EZ Gateway is the last device on the serial trunk, then the End-Of-Line Termination Switch needs to
be enabled. To enable the Termination Resistor, move the TERM dip switch to the right in the

orientation shown in Figure 4.

Termination resistor is also used to reduce noise. It pulls the two lines of an idle bus together. However,
the resistor would override the effect of any bias resistors if connected.

NOTE: The R1 and R2 DIP Switches apply settings to the respective serial port.
NOTE: If the gateway is already powered on, DIP switch settings will not take effect unless the

unit is power cycled.

Appendix A Troubleshooting

Appendix A.1. Communicating with the EZ Gateway Over the Network

• Confirm that the network cabling is correct.

• Confirm that the computer network card is operational and correctly configured.

• Confirm that there is an Ethernet adapter installed in the PC’s Device Manager List, and that it is

configured to run the TCP/IP protocol.

• Check that the IP netmask of the PC matches the EZ Gateway. The Default IP Address of the EZ
Gateway is 192.168.2.X, Subnet Mask is 255.255.255.0.

o Go to Start|Run
o Type in “ipconfig”
o The account settings should be displayed
o Ensure that the IP Address is 102.168.2.X and the netmask 255.255.255.0

• Ensure that the PC and EZ Gateway are on the same IP Network, or assign a Static IP Address to
the PC on the 192.168.2.X network.

Appendix A.2. Notes Regarding Subnets and Subnet Masks

RFC standards allocate the IP Address range of 192.0.0.0 through to 223.255.255.255 to be used in
Class-C subnetting (subnets listed as 255.255.255.xxx, where xxx can vary based on filtering required).

Consequently, the IP stack for this product will not allow any IP Addresses in this range to be allocated a
subnet that does not fall within the Class C range.

Appendix A.3. Before Contacting Technical Support Take a Diagnostic Capture

When there is a problem on-site that cannot easily be resolved, perform a diagnostic capture before
contacting support so that support can quickly solve the problem. There are two methods for taking
diagnostic captures:

• FieldServer Toolbox:

This method requires installation of the FS Toolbox program. A FS Toolbox diagnostic capture
takes a snapshot of the loaded configuration files and a log of all the communications on the
serial ports over a specified period of time. If the problem occurs over an Ethernet connection,
then take a Wire Shark capture.

• Gateway’s FS-GUI Page:

This method doesn’t require downloading software. The diagnostic capture utilities are embedded

in the FS-GUI web interface. Starting a diagnostic capture takes a snapshot of the loaded
configuration files and a log of all the communications over a specified period of time. This works
for both serial and Ethernet connections.

NOTE: The information in the zipped files contains everything support needs to quickly resolve

problems that occur on-site.

Appendix A.3.1. Using the FieldServer Toolbox

Once the Diagnostic Capture is complete, email it to technical support. The Diagnostic Capture
will accelerate diagnosis of the problem.

NOTE: While all necessary documentation is shipped with the FieldServer on the USB flash drive,

these documents are constantly being updated. Newer versions may be available on the

Sierra Monitor website.

• Ensure that FieldServer Toolbox is loaded onto the local PC. Otherwise, download the

FieldServer-Toolbox.zip via the Sierra Monitor Software Downloads.

• Extract the executable file and complete the installation.

• Connect a standard Cat-5 Ethernet cable between the PC and FieldServer.

• Double click on the FS Toolbox Utility.

Figure 48: Ethernet Port Location

• Step 1: Take a Log

o Click on the diagnose icon of the desired device

o Ensure “Full Diagnostic" is selected (this is the default)

NOTE: If desired, the default capture period can be changed.

EZ Gateway Modbus to BACnet Start-up Guide

Page 43 of 49

o Click on “Start Diagnostic”

o Wait for Capture period to finish, then the Diagnostic Test Complete window will appear

• Step 2: Send Log

o Once the Diagnostic test is complete, a .zip file will be saved on the PC

o Choose “Open” to launch explorer and have it point directly at the correct folder
o Send the Diagnostic zip file to [e-mail]

EZ Gateway Modbus to BACnet Start-up Guide

Page 44 of 49

Appendix A.3.2. Using FS-GUI

Diagnostic Capture with FS-GUI is only available on FieldServers with a bios updated/released on
November 2017 or later. Completing a Diagnostic Capture through the FieldServer allows network
connections (such as Ethernet and Wi-Fi) to be captured.

Once the Diagnostic Capture is complete, email it to technical support. The Diagnostic Capture
will accelerate diagnosis of the problem.

• Open the FieldServer FS-GUI page.

• Click on Diagnostics in the Navigation panel.

• Go to Full Diagnostic and select the capture period.

• Click the Start button under the Full Diagnostic heading to start the capture.

o When the capture period is finished, a Download button will appear next to the Start button

• Click Download for the capture to be downloaded to the local PC.

• Send the diagnostic zip file to [e-mail].
