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 Troubleshooting, 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 Grid FieldServer Manager. See Section 7.6.1

Accessing the FieldServer Manager for further information.

1.1 Certification

BTL Mark – BACnet Testing Laboratory

The BTL Mark on the FieldServer 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 for more information about the BACnet Testing Laboratory. Click

here for the BACnet PIC Statement. BACnet is a registered trademark of ASHRAE.

3 Installation

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

above.

The 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the Termination and Bias Resistance Enote for additional information.

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 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 above.

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.

3.2 Connecting the R1 & R2 Ports

For the R1 Port only: Switch between RS-485 and RS-232 by moving the number 4 DIP Switch left for RS-485 and right

for RS-232 (see images in Section 3.1 DIP Switch Settings).

The R2 Port is RS-485.

Connect to the 3-pin connector(s) as shown below.

3.2.2 Supported RS-485 Baud Rates by Protocol

The supported baud rates for either port is based on the protocol of the connected devices.

The following baud rates are supported for Modbus RTU:

2400, 4800, 9600, 19200, 38400, 57600, 76800, 115200

The following baud rates are supported for BACnet MS/TP:

9600, 19200, 38400, 76800, 115200
