C HAPTER SYSTEM OVERVIEW CHAPTER 0 1.1. Product Description The Wireless Gateway is a wireless acquisition appliance that helps monitor remote facilities. The Wireless Gateway receives 418 and 900 MHZ signals from wireless devices and relays them to facilities monitoring systems as SNMP, Modbus TCP/IP, Modbus RTU, BACnet/IP, and BACnet MS/TP signals. The Wireless Gateway’s wireless sensors can receive signals from products providing dry contact, analog (0-20mA), 0-5VDC, or 0-10VDC signals.
1 System Overview 1.3. Terminal Block Designations Figure 1.1 Terminal Block Locations Item Description Antenna 916 MHz RP-SMA connector Antenna 418 MHz RP-SMA connector Power 24 VDC/VAC Power terminal block Jack Wall wart adapter connector Status Status LED RS232 Port DB9 female connector RX TX RS485 LED Receive/Transmit status LED RS485 Termination switch 1 (unused); 2 100 ohm termination RS485 port EIA-485 circuit connector RJ45 Ethernet port 10/100 BASE-T connector Table 1.
C HAPTER GETTING STARTED CHAPTER 0 2.1. Installation The Wireless Gateway comes with two brackets that, when attached to the device, allow it to be mounted in a 19-inch rack. Remove the screws from the side of the device, put the brackets in place, and reapply the screws. Mount the device in a rack. Use the proper anchoring method to mount the unit securely. MOUNTING BRACKETS 2.2. Wiring 2.2.
2 Getting Started Figure 2.1 24VDC Power Supply Connection If the EIA-485 port will be used for Modbus RTU communication, RLE Technologies recommends an 18AWG shielded twisted pair stranded copper wire for the connection, using no more than 2000 feet (609.6m) of wire at this specification. If longer runs are needed, please contact RLE Technologies. The Wireless Gateway is shipped with a 418 MHz, 6-foot cable antenna and a 916 MHz, 6-foot cable antenna.
2 Getting Started Figure 2.3 Ethernet Connection to a PC Using a Crossover Cable Figure 2.4 Ethernet Connection to a PC on a Subnet, Using a Hub/Switch and CAT5 Cables 2.3.2 EIA-232 COM Connection The Wireless Gateway can be connected directly to a PC through its EIA-232 port. This is useful for IP configuration, firmware downloads, and troubleshooting. The EIA-232 connection is only used as a temporary connection. Connect the straight through, 9-pin serial cable as shown in Figure 2.5. Figure 2.
2 Getting Started 2.3.3 Modbus EIA-485 Connections The Wireless Gateway can function as a Modbus Slave over an EIA-485, 2-wire hardware connection, as shown in Figure 2.6. Figure 2.6 EIA-485 Connection www.rletech.com 16 970.484.
2 Getting Started 2.4. Communication: Set the IP Address The Wireless Gateway will not communicate over a user’s network the first time it is connected. This is because the manufacturer programs the device with a default IP address: 10.0.0.188, Subnet Mask: 255.255.255.0. This default address must be changed to an IP address that corresponds with the user’s network before the Wireless Gateway can communicate over the network.
2 Getting Started 9 The computer and the Wireless Gateway are now both configured to communicate on the network. Both should be accessible via the network. Connect the PC and the Wireless Gateway to the network. From the PC web browser, type in the new IP address of the Wireless Gateway. Enter the user name and password as stated above to verify network access to the device. 2.4.
2 Getting Started 2.5. Sensor Discovery The Wireless Gateway is equipped with a sensor discovery feature. The device will discover available wireless sensor inputs and enter them into the Sensor Summary page. To configure sensors to use with the Wireless Gateway, follow these steps: 1 In the Wireless Gateway’s user interface, go to the Configuration>FDS-Wi page. If it is not already enabled, click the Enabled radio button for Sensor Discovery. Figure 2.
2 Getting Started 4 Turn the sensor over to show the product label on the bottom. This label contains the serial number of the sensor. The serial number is unique to each sensor, and appears in the table on the Configuration>Sensors page once the sensor has been discovered by the Wireless Gateway. Figure 2.10 Sensor’s Serial Number on Product Label 5 Go to the Configuration>Sensors page of the Wireless Gateway’s user interface and confirm the placement in the sensor discovery list. Figure 2.
2 Getting Started 7 Once the sensors have been discovered, turn off the Sensor Discovery option in the Configuration>FDS-Wi page of the Wireless Gateway’s user interface. If you do not turn off the sensor discovery feature, the Wireless Gateway will continue to attempt to find new sensors. This could cause a device malfunction, or contaminate your list of active sensors with additional sensors that do not actually exist. 8 Note each sensor’s index number and location.
2 Getting Started 2 Make sure the back of the sensor is clean. If necessary, use isopropyl alcohol to clean the sensor. 3 Remove the protective film from the adhesive side of the magnetic tape and place the tape on the sensor. 4 Place the sensor in the desired location. www.rletech.com 22 970.484.

A PPENDIX MODBUS COMMUNICATIONS CHAPTER 0 A.1. Implementation Basics The Wireless Gateway is capable of communicating via the half-duplex EIA-485 serial communication standard. The Wireless Gateway is configured to act as a slave device on a common network. The EIA-485 medium allows for multiple devices on a multi-drop network. The Wireless Gateway is a slave only device and will never initiate a communications sequence. A.1.
A Modbus Communications A.1.1.3 Data Field The data field of the request is a variable length depending on the function. The data fields for the Wireless Gateway are 16-bit registers, transmitted high order byte first (big-endian) A.1.1.4 Error Check (Checksum) Field The checksum field lets the receiving device determine if the packet has transmission errors. The Wireless Gateway RTU mode uses a 16-bit cyclic redundancy check (CRC-16). A.1.
