Description
EZ Gateway Modbus to BACnet Start-up Guide 7
1 About the EZ Gateway
EZ Gateway is a high performance, cost effective building and industrial automation multi-protocol gateway
providing protocol translation between serial and Ethernet, devices and networks.
NOTE: For troubleshooting assistance refer to Section 10, or any of the troubleshooting
appendices in the related driver supplements. Check the MSA Safety website for technical
support resources and documentation that may be of assistance.
The EZ Gateway is cloud ready and connects with MSA Safety’s SMC Cloud. See Section 7.6.1 for further
information.
1.1 Certification
BTL Mark –BACnet Testing Laboratory
1
The BTL Mark on EZ Gateway is a symbol that indicates that a product has passed
a series of rigorous tests conducted by an independent laboratory which verifies
that the product correctly implements the BACnet features claimed in the listing.
The mark is a symbol of a high-quality BACnet product.
Go to www.BACnetInternational.net formore information about the BACnet Testing
Laboratory. Click here for the BACnet PIC Statement.
1.2 Supplied Equipment

3 Installing the EZ Gateway
3.1 DIP Switch Settings
3.1.1 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.

3.1.2 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.
