The ESTeem can support Hardware flow control (RTS/CTS control lines) or Software Flow Control (XON/XOFF). Select None if no serial flow control is necessary. Maximum Bridge Links for Multicast Packets This value sets the maximum number of Ethernet bridge links that the multicast packets will be sent through when used in a multipoint system. A multi‐point serial network uses multicast packets (UDP) to send the data to more than one remote ESTeem. You want to limit the number of network bridge links that these UDP packets will be passed through to make the network more efficient. Revised: 09 Aug 2016 ESTeem Models 210CM...
Page 34
CHAPTER 5 SERIAL APPLICATIONS If you are using multiple ESTeem repeater links to send the serial data to remote locations, the value for the maximum bridge link needs to be increased to a number greater than the longest repeater chain. For example, if you are using four repeater (peer) links to send the serial data between two or more sites the number will need to be five (5) or greater (Figure 2). Figure 2: Serial Configuration Screen Destination IP Address The ESTeem configured for the correct destination IP and port number will send and receive the serial data from another modem. Set the destination IP address for the ESTeem where the serial data will be sent. If sending to more than one ESTeem (Multipoint) set to a multicast address (i.e 224.0.0.1). Serial IP Port Number The ESTeem configured for the correct destination IP and port number will send and receive the serial data from another modem. Set the IP port numbers to match where the serial data will be sent. The serial data will not be sent if both the IP address and port number is not correct. Maximum Packet Size This number represents the maximum size of the serial data packet in bytes. If the number of bytes of data in the serial port buffer exceeds the maximum packet size before the timer or delimiter character is reached, the ESTeem will send forward the serial packet. For example, if the maximum packet size is set to a value of 100, when the serial port receives 100 bytes the data will be sent through the wireless connection. Number of Milliseconds for Packetization This number represents the time the ESTeem will hold data in the serial data buffer before sending to the remote ESTeem. This feature is generally used if the serial data does not have a consistent packet length or delimiter character. For example, if the Revised: 09 Aug 2016 ESTeem Models 210CM...

Tip: While the 210 does support Mesh One of the most powerful features of the AP Repeater Mode is the Networking keeping the amount of Mesh Nodes to ability to input multiple communication routes and designate the less than 6 will help with network throughput. priority for each of these routes to create a wireless Mesh network. The ESTeem Model 210 will automatically change communication routes in the network if a route has failed. The new route will be based upon the priority level set during configuration. This wireless Meshing technology allows the RF network to “self‐heal” if any of the communication paths fail. The routing priority is manually set during the configuration of the Peer links in the 210. A manual path configuration is far superior to standard “self‐discovery” networks, because you have direct control over the best RF paths and can easily identify any failed routes for easy troubleshooting. For example, Figure 1 shows a typical wireless Ethernet system used in the Water/Waste Water Industry. The problem with a standard “self‐discovery” Mesh network is the selection of routes. Notice that the communication between the Water Plant (Site A) and Pump Site D has a marginal link, but it is the most direct route between the Ethernet devices. This scenario poses the question, which path will the network select? The ESTeem Mesh Network takes out the guessing games by allowing the user to select and prioritize all communication routes in the system. In our example we would want the primary link to go through Tank B (Repeater) and use the direct link only if this primary link fails. The following sections will show how this completed.

CHAPTER 6 REPEATING FEATURES The configuration of the repeater paths is completed during setup of the Access Point Bridge mode (Figure 2). For Mesh configuration to operate, all AP Bridge ESTeem 210’s in the same network need to have Spanning Tree Protocol (STP) set to YES (Figure 2). Figure 2: Peer Configuration Screen Figure 3: Peer Configuration Example Figure 2 shows an example repeater peer table from the setup menus. For an ESTeem 210 in AP Bridge mode to communicate with another ESTeem 210 in Bridge mode, press Add button on the Peer configuration page and Figure 3 will be displayed. Next, the serial number or Wireless LAN (WLAN) MAC address of the Model 210 that will have direct communications must be added Revised: 09 Aug 2016 ESTeem Models 210CM...
CHAPTER 6 REPEATING FEATURES to the Peer List (Figure 3). Finally, enabling the link allows the corresponding 210 to be included in the communication routing. ESTeem 210 radio modems in Station Bridge mode do not require input in the repeater peer table. If multiple Mesh routes are configured, you will also need to set the values for Priority and Path Costs (explained in Spanning Tree below). For multiple examples of repeater configurations, please refer to Chapter 3 of this user’s manual. SPANNING TREE PROTOCOL (STP) The ESTeem Model 210 uses standard Ethernet Spanning Tree Protocol (STP) or Rapid Spanning Tree Protocol (RSTP) to determine the radio routing structure of the wireless network. The primary purpose of STP/RSTP is to make sure that “network loops” are not created. A network loop is having two communication paths to the same destination where the remote device would receive the same data multiple times. If there were no way to control the data flow, this data would be constantly passed around this loop causing a “packet storm” that would shut down the entire network. The Spanning Tree Protocol will block all these redundant links. The STP operation begins by determining which Ethernet device on the network will be the Root Bridge. All Ethernet networks have a Root Bridge that is selected by the lowest MAC address. All path costs are evaluated against this Root Bridge device to determine routing and which paths will be blocked. On a wired Ethernet network, the location of the Root Bridge is not really important, but in a wireless network selection of the Root Bridge is critical to the wireless network routing. Let’s use the following Example network diagram (Figure 4) to continue the discussion. Figure 4: Programming Example #1 Diagram Revised: 09 Aug 2016 ESTeem Models 210CM...
Path Length If more than one communication path to the Root Bridge is found, the 210 must determine which route to take based upon the lowest Path Length. The default path length to all links in the 210 network is 1. If the Path Lengths are equal then the lowest MAC address will determine the priority route. In the ESTeem Mesh Network we want to directly control all data flow so do not want the routes to be automatically determined. Looking again at our Example in Figure 4, if we made no changes to the default path length of 1 (note values in Figure 3) the lowest path cost would be direct from the Remote Building to the Root Bridge (Plant Network). Link Description Total Path Length Direct from Remote Building 1 Remote Build to Root Bridge Through Repeater 2 (Length 1 to repeater + Length 1 to Master = 2) To configure the 210 to select the repeater as the primary radio path, set the path length value for the direct link greater than 2 (such as a value of 3) to make this the primary radio path. The lowest path length will identify the highest priority. The Model 210 will use this routing, but also switch to direct communication if the repeater were to disappear. Root Bridge In any Access Point Repeater network consisting of more than two sites, one Model 210 should be designated as the Root Bridge. Only one Model 210 can be designated as the Root Bridge in a given network and should be located where the majority of the Ethernet data flow is processed. This site may be the Master location in a SCADA network or could be configured at a repeater site. Selection is important because all Model 210’s NOT configured as the Root Bridge will choose routing based upon the Path Length to the Root Bridge. If you have any question as to which site in your AP Repeater application should be the Root Bridge, contact ESTeem Customer Support at 509‐735‐9092 or e‐mail your application to support@esteem.com.

Keep the antenna feedline as short as possible to minimize losses. Extreme care must be taken when attaching coax connectors to the antenna feedlines. If there is any error in making this connection the output of the transmitter will be greatly reduced. Revised: 09 Aug 2016 ESTeem Models 210CM...
2. Wrap the connector assembly with a non‐adhesive silicone tape, EST part number AA243, for weather proofing (See Note 2 and instructions below). Clean surface to be wrapped. Cut off length to be used. Peel back a short length of protective film. Keep tape clean and dry. Begin with one complete overlap of tape onto itself. STRETCH CoaxWrap while continuing to wrap object with “half‐laps”, removing clear film as you go (Figure 1). For greater pressure resistance, use 2 or more tightly wrapped layers. End of tape at final wrap should be completely positioned onto itself. Note: CoaxWrap’s bond begins to cure immediately upon contact with itself. Repositioning or removal is not recommended after 2 minutes of wrapping. 3. Apply an electrical coating (sealing agent), over the vapor barrier patch for added protection (See Note 3).

APPENDIX C RADIO & TROUBLESHOOTING 210 FREQUENCIES OF OPERATION The ESTeem Model 210C operates from 450‐470 MHz in 12.5 KHz and 6.25 KHz channels. The ESTeem Model 210M operates from 150‐174 MHz in 12.5 KHz and 6.25 KHz channels. In a wireless Ethernet or Serial network all of the ESTeem Model 210 must be set to the same radio frequency of operation. The frequency of operation is selectable when configuring the mode of operation of the 210 (reference Chapter 3). SETTING RF POWER LEVEL The ESTeem Model 210 peak power is adjustable in output power from the advanced configuration menu. The output power is adjusted on the Advanced Menu>Wireless LAN Settings>Wlan0 Device screen (Figure 4) of the Web Configuration Manager. Select the value and press the Save Settings button.

APPENDIX C RADIO & TROUBLESHOOTING TESTING COMMUNICATION LINK After you have configured at least two of the Model 210 wireless Ethernet modems for operation, you can verify communication with each the following steps: Status Light The quickest source of link status is to view the Status Light on the face of the 210 (Figure 3). If the Status light is solid, the Model 210 has a connection to another Model 210 listed in the Peer Table or Station Bridge. Status Screen/Peer Table Figure 3: 210 Front Panel To view more detailed information on the status of the communication link (such as signal strength and last update time) you can open the Status Screen from the Web Interface. After press the Status tab at the top of the screen the Status: Summary will be displayed showing the status of all ports and memory in the 210.

APPENDIX C RADIO & TROUBLESHOOTING Station Connections – This section will list all 210 radio modems are linked as Station Bridges. Ping Testing – The easiest method for testing the efficiency of data flow between the ESTeems is to conduct a Ping test to the opposite modem’s IP address. This will test all links in the Ethernet Bridge. Figure 5: Ping Test Example Receive Signal Strength (RSSI) Indicator The ESTeem Model 210 series has a receive signal strength indicator located on the front panel (Figure 3). The RSSI indictor will display the receive signal strength of the last received RF packet. The RSSI indicator has four LED’s with four intensity states for each LED (from left to right) for a total of 16 possible states. The signal strength starts at ‐100dBm and increases in intensity every +4dBm. The RSSI levels are listed below: RSSI LED (Reading Left to Right) Receive Signal Strength Values Light #1 ‐100dBm to ‐88dBm Light #2 ‐84dBm to ‐72dBm Light #3 ‐68dBm to ‐56dBm Light #4 ‐52dBm to ‐40dBm Revised: 3 Feb 15 APX C-3 EST P/N AA107-210CM...
APPENDIX D NETWORK OPTIMIZATION The ESTeem Model 210C and 210M is an evolving product that has greatly changed scope in use since first released. The ESTeem 210 series was first developed to provide long range access to industrial control hardware (PLC, RTU, etc.) that have moved from a serial (RS‐232) interface to an Ethernet interface. The data rate of 64.8 Kbps on a narrow‐band frequency channel is one of the fastest on the market, but is best suited for data collection and not for bridging Ethernet network segments. For applications where wireless is used to bridge Ethernet networks we generally recommend higher throughput wireless modems so that the data input is not as restricted. If the Model 210 series are installed on busy Ethernet networks or connected to plant networks, the Network Optimization features were added to optimize the radio modem to handle the network requirements. Several new features have been added to the firmware which will greatly help in your network performance. Figure 1: Network Optimization Screen Dynamic ARP Table Turning on the Dynamic Address Resolution Protocol (ARP) table will allow the ESTeem to create an actively updating Static ARP Table to remove the TCP/IP ARP requests for connected Stations and Peers from transmitting over the wireless link. If the Dynamic ARP Table is enabled, the connected ESTeem will locally respond to the ARP request for any connected remote IP addresses. This feature greatly reduces the radio traffic on the wireless network. Revised: 09 Aug 2016 APX D-1 ESTeem Models 210CM...
This newly added feature allows the Model 210 to select whether you want Broadcast/Multicast packets to be sent as Unicast or Broadcast/Multicast. It is recommended to set this feature to Yes for multicast messages. Whitelist Enabling the Whitelist and entering TCP/IP addresses in the table will Technical Tip: The connected computer’s TCP/IP designate the specific TCP/IP addresses to be processed by the Model address must also be added to the Whitelist to 210 radio modem. If a TCP/IP address is NOT in the Whitelist table, communicate with the ESTeem 210. the ESTeem will not process the data request. This feature does require more network management but can greatly reduce the wireless traffic for only specific TCP/IP addresses. Revised: 09 Aug 2016 APX D-2 ESTeem Models 210CM...
