firmware, including data encryption, enabling or disabling remote access channels, and password protection. Remember, security is not a one-step process that can be simply turned on and forgotten. It must be practiced and enforced at multiple levels, every day. Section 1.4 contains additional information about entraNET security features. License-Free Operation The transceivers are designed for frequency-hopping spread-spectrum operation in the license-free 900 MHz or 2400 MHz band.
1.2.1 Model Offerings The GE MDS entraNET system includes two primary radio types— APs and Remotes. Table 1-1 summarizes the interface capabilities for each entraNET radio type. NOTE: A Remote serves only one endpoint MAC address, even if a bridge or hub is used. Table 1-1.

MDS NETview Management System (MS) software. In addition, entraNET offers nearly unlimited potential for future applications that run over IP and Ethernet services. In an IP-to-serial scenario, every Remote is sent information received by the AP Ethernet port. Likewise, information received at the Remote serial port is transmitted to the AP, and the AP delivers this information through its Ethernet port in the form of an IP packet. Additionally, the AP serial port can be used as a virtual Remote.
1.3.4 Upgrading an Older Wireless Network with Serial Interfaces Millions of wireless data products have been sold in the last two decades for licensed and license-free operation, many of them manufactured by GE MDS. There are several ways that these systems can benefit from employing GE MDS entraNET wireless equipment, including flexible serial and Ethernet interfaces, higher data throughput, and ease of installation.

2.1 INTRODUCTION Prior to installation in the field, it is recommended that you set up the radio system in an office or lab and become familiar with its operation and features. This also allows tests of various network designs and configurations prior to arrival at a field site. A tabletop test can be performed with any number of radios. This section describes the hardware setup and software configuration needed for testing an Ethernet connection.

AP Interface Connectors Figure 2-2 shows the interface connectors for the Remote transceiver.
STEP 1—CONNECT THE ANTENNA PORTS Figure 2-3 is a drawing of a tabletop arrangement. Connect the antenna ports of each transceiver as shown through attenuators and an RF power divider. This provides for stable communications between each radio, while preventing interference to nearby electronic equipment.
Invisible place holder Lead Binding Screws (2) Wire Ports Figure 2-4. Power Connector (polarity: left +, right –) CAUTION POSSIBLE POSSIBLE EQUIPMENT EQUIPMENT DAMAGE DAMAGE Power Supply Connections at 28 Vdc The transceiver must be used only with negative-ground systems. Make sure the polarity of the power source is correct. The radio is protected from reverse polarity by an internal diode and an on-board fuse.
• Minimize the length of the power cabling, within reason. • When power is applied from a power source having a relatively high (1 or 2 Ω) source impedance, or from a power source without a large amount of output capacitance, no overshoot occurs. Therefore, use a power supply that is rated appropriately for the radio if possible—avoid using power supplies that far exceed the radio's current requirements.
NOTE: The exact parameters given above must be used for console terminal communication. Improper settings are a common cause of difficulty. Telnet Connection Using the AP LAN Port (a valid IP address must be set) To configure the AP via its LAN port: 1. Connect a PC Ethernet port to the AP with an Ethernet crossover cable. NOTE: The radio must first have a valid IP address programmed—the default IP address is 192.168.1.1. 2. Log in to the AP as follows: a. Press the ENTER key to receive the login prompt.

Conceptual Views of Radio System Usage The AP includes an embedded terminal server that provides access to Remote serial ports via an IP or serial connection at the AP.
Most polled protocols are best served by UDP services, as the protocol itself has built-in recovery mechanisms (error correction). UDP provides the needed multidrop operation by means of multicast addressing, where multiple remote devices receive and process the same poll message. On the other hand, TCP services are best suited for applications that do not have a recovery mechanism and must have the guaranteed delivery that TCP provides despite its extra overhead.
3.6.2 Local Serial Configuration Menu Figure 3-22. COM1/2—Local Serial Configuration Menu • Port Status (COM1, COM2)—Defines whether the specified port is enabled or disabled to pass payload data. COM1 is typically disabled to allow it to be used for console terminal control. NOTE: If COM1 is inadvertently enabled, it will become impossible to log in using a console terminal connected to the COM1 connector.

This allows selection of either image to be transmitted to the remote. • Send Images—Begins transmitting the selected firmware image to the Remote. • Remote Reboot—Restarts the Remote radio with one of the two firmware images.
Broadcast reprogramming with different firmware versions on a network Broadcast reprogramming is used to upgrade the firmware of all radios in a network. If your network contains a mix of radios with 2.x and 3.x version firmware, it is normal to see the status message “Some Remotes Failed Programming”. For example, if you select 2.x firmware to reprogram, only the older remotes will accept the image; if you select 3.x firmware, only new remotes will accept the firmware. Release 3.

TXDELAY= —Sets the inter-packet delay in milliseconds (1-65535). The minimum TXDELAY setting should be set to two times the Dwelltime setting. When TXDELAY is set to less than twice the Dwelltime setting, the measured inter-packet delay can increase up to one dwelltime (7,14, or 28 ms) period. COM2 Sets or displays the COM2 port configuration. Optional arguments: BAUD=—Sets or displays baud rate setting as 1200, 2400, 4800, 9600, 19200, 38400, 57600, or 115200 bps.
NOTE: You can use the CTS output from an entraNET radio for Data Carrier Detect (DCD) sense. It is always asserted (high) when flow control is set to NONE. The radio asserts this line as long as it can accept data on the serial port. When the radio’s internal serial buffers are full and it can’t accept any more data on the port, it deasserts (low) the CTS line. CTS_CTRL: CTS_RTS: CTS follows RTS logic.

6.1 INSTALLATION This section provides tips for selecting an appropriate site, choosing an antenna system, and reducing the chance of harmful interference. 6.1.1 General Requirements There are three main requirements for installing a transceiver—adequate and stable primary power, a good antenna system, and the correct interface between the transceiver and the data device. Figure 6-1 shows a typical Remote installation.
6.1.3 Conducting a Site Survey If you are in doubt about the suitability of the radio sites in your system, it is best to evaluate them before a permanent installation is begun. This can be done with an on-the-air test (the preferred method); or indirectly, using path-study software. An on-the-air test is preferred because it allows you to see firsthand the factors involved at an installation site and to directly observe the quality of system operation.
some level of interference should be expected. However, flexible design and hopping techniques should allow adequate performance, as long as care is taken in choosing station location, configuration of radio parameters, and software or protocol techniques.
Mounting Dimensions for Radios Figure 6-2 shows the dimensions of the AP transceiver with mounting brackets attached. Figure 6-3 shows the same view for a Remote transceiver. When mounting entraNET transceivers, choose a location that provides easy access to the connectors on the end of the radio and an unobstructed view of the LED status indicators.

Antennas are available from a number of manufacturers. Invisible place holder Figure 6-6. Typical Yagi Antenna (mounted to mast) NOTE: It is essential that all antenna systems incorporate appropriate lightning protection.
For 900 MHz systems with cable runs of less than 20 ft./6m, an inexpensive cable type such as Type RG-8A/U may be acceptable. For longer runs, or for 2400 MHz systems, we recommend using a low-loss cable type such as Andrew Corp. HELIAX® cable. The choice of cable depends on the required length, cost considerations, and the amount of signal loss that can be tolerated.
6.2 HOW MUCH OUTPUT POWER CAN BE USED? (U.S.A. and Canada, 900 MHz systems) 900 MHz transceivers are normally supplied from the factory set for +30 dBm (1 Watt) RF power output; this is the maximum transmitter output power allowed under FCC and Industry Canada rules. The power must be decreased from this level if the antenna system gain exceeds 6 dBi. The allowable level is dependent on the antenna gain, feedline loss, and the transmitter output power setting.
gain of 6 dB or less entitles you to operate the radio at full power output 30 dBm (1 Watt). Table 6-4. Antenna System Gain versus Power Output Setting (U.S.A. and Canada only) Antenna System Gain Maximum Power Setting EIRP (in dBm) (in dBm) 6 (or less) 30 36 8 28 36 10 26 36 12 24 36 14 22 36 16 20 36 (Antenna Gain in dBi* minus Feedline Loss in dB†) * Most antenna manufacturers rate antenna gain in dBd in their literature. To convert to dBi, add 2.15 dB.
1. Determine the antenna system gain by subtracting the feedline loss (in dB) from the antenna gain (in dBi). For example, if the antenna gain is 10 dBi, and the feedline loss is 2 dB, the antenna system gain is 8 dB. 2. Subtract the antenna system gain from 27 dBm (the maximum allowable EIRP). The result indicates the maximum transmitter power (in dBm) allowed under the rules. In the example above, this is 19 dBm. 3.
NOTE: Some EU countries mandate lower power outputs and frequency limitations from those referenced here. For example, in France, the transceiver may only be operated in band C (2.4528-2.4782 GHz) at a power level of 10 dBm. Be sure to check the requirements for your region before placing the transmitter on the air. 6.4.1 Calculating System Gain To determine the maximum allowable power setting of the radio, perform the following steps: 1.
6.5 OPTIMIZING PERFORMANCE After the basic operation of the radio has been established, you may wish to optimize network performance using some of the suggestions in this section. The effectiveness of these techniques vary with the design of your system and the format of the data being sent. There are two major areas for possible improvement—the radio and the data network.
• The number of bytes they can fit into a hop, depending on hop time, is: Table 6-1. Number of bytes per hop Hop time (MS) FEC Bytes/hop 7 45 7 FEC 14 11 139 14 FEC 59 FEC 151 28 324 28 Included in the byte count is 9 bytes of overhead per packet. So, at 7MS without FEC, a 1000 byte packet requires 1009 bytes split into 45 bytes/hop, or 23 hops. 1026 bytes of data also requires 23 hops; however, a 1027-byte data packet requires 24 hops.
6.5.2 Aiming Directive Antennas for Maximum RSSI The wireless network integrity depends, in a large part, on stable radio signal levels being received at each end of a data link. In general, signal levels stronger than –90 dBm provides the basis for reliable communication that includes a 15 dB fade margin.
6. View the Radio Retries and No Ack counts at the point of maximum RSSI level. They should be the same or lower than the previous reading. (Main Menu > Performance Information > Packet Statistics > Wireless Packet Statistics) If the RSSI peak results in an increase in the Radio Retries and No Ack counts, the antenna may be aimed at an undesired signal source. Try a different antenna orientation. 6.5.
NOTE: Reprogramming does not work over the air when the settings Hop Time=7, FEC=On and Encryption=On are used at the AP. To Maximize Overall Data Performance • Change the Buffer Size for serial ports to the maximum of 1500. Longer packets are sent over the air, reducing overhead. On the down side, if a packet is corrupted, it takes longer to be retransmitted. • Use the Packet Statistics Menu to check Packets Received by Zone. Counts should be evenly distributed across all zones.

7.1 TROUBLESHOOTING Successful troubleshooting of a wireless system is not difficult, but requires a logical approach. It is best to begin troubleshooting at the AP radio, as the rest of the system depends on the AP for synchronization data. If the AP has problems, the operation of the entire wireless network is affected. When communication problems are found, it is good practice to begin by checking the simple things.
Table 7-1. Symptom-Based Troubleshooting Using LEDs Symptom Possible Cause and Resolution PWR LED does not turn on. a. The voltage is too low, or is the wrong polarity. Check for the proper supply voltage at the power connector (6–30 Vdc). See Figure 2-4 on Page 20 for polarity details. b. This is a transient condition. Cycle the power and wait about 30 seconds for the radio to restart. Recheck for normal operation. LINK LED does not turn on. a. The Remote network address does not match the desired AP.
may be used remotely to provide preliminary diagnostic information, or may even provide a path to correcting the problem. Table 7-3. Troubleshooting with the Embedded Management System Symptom Possible Cause and Resolution Remote does not associate a. Verify that the AP has a sufficiently large number in the “Max Remotes” parameter of the Network Configuration Menu. b.
Table 7-3. Troubleshooting with the Embedded Management System (Continued) Symptom Possible Cause and Resolution Cannot pass IP data to the WAN. a. Verify the AP IP settings. b. Use the PING command to test communication with the AP and endpoints connected to Remote radios in the local radio system. c. If successful with the local PING, attempt to PING an IP radio attached to a radio. d. If successful with the LAN PINGs, try connecting to a known radio in the WAN.
The most significant fields are Retries, Retry Errors, Receive Errors, and Lost Carrier Detected. If the data values are more than 10% of their sent and received counterparts, or the Lost Carrier Detected value is greater than a few dozen, there may be trouble with interference, or a loss of the Ethernet signal. Note that this does not refer to the over-the-air (RF) carrier, but only to the Ethernet carrier.
7.1.3 Using Logged Operation Events (See Event Log Menu on Page 82) The transceiver microprocessor monitors many operational parameters and logs them as various classes of “events.” If the event is one that affects performance, it is an “alarmed” event. There are also normal or routine events such as those marking the restarting of the system, implementation of parameter changes, and external access to the entraNET MS.

8.1 UPGRADING AP FIRMWARE GE MDS occasionally offers upgrades to the transceiver firmware. One version of the firmware provides core software resources for all radio models. Uploading new firmware into the radio does not alter any privileges provided by Authorization Keys, and does not require the transceiver to be taken offline until you want to operate the radio from the new firmware image in the radio. You must use the entraNET MS for all firmware activities, including uploading from a TFTP server.

The following glossary explains many of these terms and is helpful in understanding the operation of the transceiver system. Access Point (AP)—The transceiver in the network that provides synchronization information to one or more associated Remote radios.
DCE—Data Communications Equipment. In data communications terminology, this is the “modem” side of a computer-to-modem connection. The transceiver COM1 and COM2 ports are set as DCE. Decibel (dB)—A measure of the ratio between two signal levels. Frequently used to express the gain (or loss) of a system. DES—Data Encryption Standard. More information on DES is available at www.itl.nist.gov/fipspubs/fip46-2.htm. DHCP—Dynamic Host Configuration Protocol.
FHSS—Frequency Hopping Spread Spectrum. A common transmission technique used by license-free transceivers. Frame—A segment of data that adheres to a specific data protocol and contains definite start and end points. It provides a method of synchronizing transmissions. Frequency Hopping—The spread spectrum technique used by the transceivers, where two or more associated radios change their operating frequencies several times per second using a set pattern.
kbps—kilobits per second. See bps. LAN—Local Area Network Latency—The delay (usually expressed in milliseconds) between when data is applied at the transmit port at one radio, until it appears at the receive port at the other radio. MAS—Multiple Address System. A radio system where a central master station communicates with several remote stations for the purpose of gathering telemetry data. Figure 1-2 on Page 7 shows an example of an MAS system. MCU—Microcontroller Unit.
Point-Multipoint System—A radio communications network or system designed with a central control station that exchanges data with a number of remote locations equipped with terminal equipment. Poll—A request for data issued from the host computer (or master PLC) to a Remote radio. Portability—Refers to the ability of a transceiver to connect to an AP from multiple locations without the need to reconfigure the network settings.
STP—Spanning Tree Protocol Standing-Wave Ratio—See SWR. SWR—Standing-Wave Ratio. A parameter related to the ratio between forward transmitter power and the reflected power from the antenna system. As a general guideline, reflected power should not exceed 10% of the forward power (≈ 2:1 SWR). TCP—Transmission Control Protocol. A “guaranteed delivery” protocol used to set up a connection between two devices with acknowledgements (ACK/NACK), and retries if the data is not received properly.
