Transceiver Installation Overview Transceiver Installation Overview To successfully install a transceiver, follow the basic steps listed below. 1. Determine the best location for the transceiver. 2. Install the ground rod. 3. Install the NEMA 4 enclosure 4. Mount the transceiver and power supply into the enclosure. 5. Route data cables to the end device. 6. Connect power and configure the transceiver. 7. Install the antenna. 8.
2.4 GHz Wireless Data Transceivers Warning! Do not use Velcro to mount the transceiver. Attaching and detaching Velcro pieces creates an electro-static discharge that may damage the transceiver's circuitry, or other electronic devices nearby. Mounting a transceiver to a metal surface may result in an electrical short across the transceiver. Removing Velcro also creates stress points on board-level transceivers with a great potential to damage the solder points.
Mounting the Transceiver in the NEMA Enclosure l 1 - Mounting shoe l 4 - #8 x 3/4 inch self tapping screws Depending on your setup, it may be helpful to note the transceiver's serial number and any other information needed from the transceiver's label. The transceiver snaps out of the mounting shoe if you need to access the label information at a later time. The mounting shoe is designed to securely grip the transceiver, allowing it to be mounted either horizontally or vertically. 1.
2.4 GHz Wireless Data Transceivers l 8 - 4-40 x 1/4 inch screws l 4 - standoffs Important: Prior to mounting the bracket to an enclosed transceiver, note the transceiver's serial number and any other information you might need from the transceiver's label. After the bracket is attached to the transceiver, the label is no longer accessible without unscrewing the bracket in its entirety.
Mounting the Transceiver in the NEMA Enclosure 3. With the spring guide facing down and with the transceiver's RF connector facing up, attach the transceiver to the rail by pressing the spring loaded guide onto the rail edge. Push the fixed guide onto the other side of the rail. The guides on the contact foot allow the transceiver to be installed vertically or horizontally on the din rail mount.
2.4 GHz Wireless Data Transceivers l 8 - lock washers l 8 - 4-40 x 1/4 inch screws l 4 - standoffs Depending on the setup, it may be helpful to note the transceiver's serial number and any other information needed from the transceiver's label. 1. Place lock washers on all eight of the screws. 2. Attach the standoffs to the front side (non-flat side) of the transceiver with four screws. 3. Align standoffs with the bracket holes and secure with the other four screws.
Configuring the Transceiver situation. Using both helps enhances reliable operation and can be purchased at most electronic supply stores. Warning! If the power supply is above +18.0 VDC, use a 1 ohm resistor inline with power input to the transceiver. For more information, see application note #5467: Power Wiring Precaution for FGR-Series at High Supply. The cautions outlined in the application note also apply to the GX family transceivers.
2.4 GHz Wireless Data Transceivers 1. Plug a serial cable into the COM 1 port on the transceiver, connect the cable to a COM port on the computer running Tool Suite, and connect the transceiver to a power source. 2. Open Tool Suite and select Setup Terminal in the Applications pane. 3. From the drop-down list at the top left of the window, select the COM port on the computer to which the transceiver is connected. 4. Click Connect.
Installing the Antenna Warning! Any antenna placed outdoors must be properly grounded. Use extreme caution when installing antennas and follow all instructions included with the antenna. Per FCC regulations, any antenna used with FreeWave transceivers must be an approved antenna that has comparable performance parameters. For more information about approved antennas, see "Approved Antennas" на стр.11.
2.4 GHz Wireless Data Transceivers Cable Loss and Transmit Power Settings The Transmit Power parameter is the output power of the transceiver. The transceiver output power level must be set to satisfy maximum Effective Isotropically Radiated Power (EIRP) requirements in the country in which the installation exists.
Cable Loss and Transmit Power Settings When setting up the network, consider the power gain that an antenna may add, and the power loss through cabling. Adjust the Transmit Power on the transceiver to ensure that you do not exceed the maximum EIRP for the regulating body where the installation exists. Use the tables below to determine the correct Transmit Power parameter setting for each transceiver in the network. Important: The information in this section discusses FCC and ETSI maximum EIRP regulations.
2.4 GHz Wireless Data Transceivers The following table demonstrates how the Transmit Power parameter setting on the transceiver corresponds to the EIRP in dBm with the transceiver-cable-antenna combination for a 4 dBi Yagi antenna at different cable losses in a Point-to-MultiPoint or Point-to-Point network. Note: ETSI regulations allow only 20 dBm. Networks with 4.
Board-Level and DB9 Pinouts Board-Level and DB9 Pinouts The information in the following sections provides the pinout connection information for the connectors on the transceivers. RF Board Level Pinout The board-level transceivers are available in both TTL and RS232 versions. The TTL version uses reverse polarity from standard RS232 at 0 to 5 Volt levels. All pin descriptions and pin numbering are the same as the RS232 version.
