EQUIPMENT SETUP
Mounting
The gateway can be mounted using the DIN rail mounting bracket on the back of
the unit.
Physical Dimensions
INSTALLATION
DIP Switch Settings
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 Field Servers can be put on the network without running into the bias
resistor limit, which is < 500 ohms.
NOTE: See
ni.com/support/serial/resinfo.htm
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.
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 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 ispower cycled.
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 inDIP Switch Setting section). The R2 port is RS-485.
Connect to the 3-pin connector(s) as shown below.
Wiring
RS-485 | RS-232 |
---|---|
BMS RS-485 Wiring | Gateway Pin |
Assignment | BMS RS-232Wiring |
Assignment
RS-485+| TX+| RS-232-| TX+
RS-485-| RX-| RS-232+| RX-
GND| GND| GND| GND
NOTE: The RS-485/RS-232 is part of the RS-485/RS-232 interface and must
be connected to the corresponding terminal on the BMS. If the cable is
shielded, the shield must be connected only at oneend and to earth ground.
This will help suppress the electromagnetic field interference. (Connecting
the shield at both ends will likely produce current loops, which could
produce noise orinterference that the shield was intended to block).
Supported RS-485 Baud Rates by Protocol
The supported baud rates for either port is based on the protocol of the
connecteddevices. 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 10/100 Ethernet Connection Port
NOTE: Do not use shielded Ethernet cables.
The Ethernet port is used both for BACnet/IP communications and for
configuring the gateway via the Web App. To connect the gateway, either
connect the PC to the router’s Ethernet port or connect the router and PC to
an Ethernet switch. Use Cat-5 cables for the connection.
NOTE: The Default IP Address of the gateway is 192.168.2.101, and the
Subnet Mask is 255.255.255.0.
NOTE: The ETH2 port can be set to WAN mode to limit Ethernet traffic. See
the WAN Mode Settings for ETH2 section for details.
NOTE: ETH1 and ETH2 must be configured with IP Addresses on different IP
subnets.
POWERING UP THE GATEWAY
Check power requirements in the table below:
Power Requirement for Field Server External Gateway
| Current Draw Type
Field Server Family| 12VDC| 24vdc/ac
FS-QS-3X109-XXXX (typical)| 250mA| 125mA
NOTE: These values are “nominal” and a safety margin should be added to
the power supply of the host system. A safety margin of 25% is recommended.
Apply power to the Field Server as shown on next page. Ensure that the power
supply used complies with the specifications provided in the Specifications
section.
-
The gateway accepts 9 to 30 VDC or 24 VAC on pins L+ and N-.
– Supports both Full-Wave and Half-Wave AC -
Frame GND should be connected to ensure personnel safety and to limit material damages due to electrical faults. Ground planes are susceptible to transient events that cause sudden surges in current. The frame ground connection provides a safe and
effective path to divert the excess current from the equipment to earth ground.
NOTE: Floating AC power supplies are supported.
