Axiometric Gateway Guide MeshPlus™ Gateway 2 User's Guide 1. Overview This document explains the features and operation of the MeshPlusTM Gateway 2. The Gateway 2 serves three main functions: Mesh controller – coordinates the wireless communication for thousands of remote MeshPlusTM devices. The Gateway 2 serves as a master timing source for all devices in a mesh.
Axiometric Gateway Guide MeshPlus™ The Gateway 2 requires an external AC (110-220VAC 50/60Hz) or DC (POE or Solar) power source and should be mounted in a location with convenient access to power. When using solar power, the solar panel should be angled towards the sun in the South to gather maximum energy. When using Power Over Ethernet (POE), the DC source voltage should be adjusted based on the length of the Ethernet cable to deliver approximately 12vdc to the Gateway 2.
Axiometric Gateway Guide MeshPlus™ The lithium battery does not supply any power to the Gateway in normal operation and has a typical service life of 10 years. When all other Gateway power sources are lost, the lithium battery can power the mesh controller and data collection functions of the Gateway 2 for over 6 months during an extended power outage ensuring that mesh operation and data collection continue without data loss. The lithium battery does not power the network bridge function.
Axiometric Gateway Guide MeshPlus™ 5. Connect the external AC or DC power source to start normal Gateway operation and begin charging the optional NiCd battery pack if present. Ensure a good ground connection is provided for AC or DC power; a missing or poor ground connection presents a serious safety hazard. Installation is complete! 3. Network Bridge The Gateway 2 is connected to a TCP/IP network via network bridge module.
Axiometric Gateway Guide MeshPlus™ • Steps 12-14 show how to configure the static IP address 172.30.1.31 and a subnet mask of 255.255.255.0 with a gateway at 172.30.1.1. You should use the parameters provided by your network administrator instead: 12. # set ip eth0 dhcp-client disable 13. # set ip eth0 ip-address 172.30.1.31 mask 255.255.255.0 14. # set ip def-gway 172.30.1.1 • Step 15 shows how to configure the Gateway 2 for DHCP: 15.
Axiometric Gateway Guide • • • • MeshPlus™ Default Gateway = 172.30.1.2 Primary DNS = 172.30.1.1 Domain = meshplus.com TCP access port 2100 You should substitute the correct values for your network. Before you start, you will need: -- Serial debug cable -- a laptop or other RS-232 Terminal (DTE) device with serial communications software *that can generate a BREAK character*.
Axiometric Gateway Guide MeshPlus™ functionality: “AT#IP?”, “AT#WLAN?”, “AT#VVERSION”, “AT#VSTATE”, “AT#VALL”, “AT&F” (restore factory defaults). Note that once this command sequence has been completed, any future changes to the WiFi configuration should skip step 4 since step 17 permanently configures the interface to 57600bps (the default).
Axiometric Gateway Guide MeshPlus™ -- setup passthrough to socketmodem: type: "console null" to relay typed characters directly to the SocketModem type: "AT" to cause modem to auto-baud (should see "OK" response) [note: you may have to do this two or three times] The SocketModem has on-board flash storage for most parameters; erase any non-volatile parameters to start from a clean slate.
Axiometric Gateway Guide MeshPlus™ (wait for "OK") -- Force attachment as class 'CG' [The default is a 'class B' device.] (GPRS-only - no voice service, no GSM service, auto-activate the IP stack, and auto-attach on power-up) type: AT+CGCLASS="CG" -- set DLE mode ON for connection ID 1 type: AT#DLEMODE=1,1 -- set TCP PORT for listen: type: AT#TCPPORT=1,2100 -- set TCP SERVER to allow incoming call from any host: type: AT#TCPSERV=1,"255.255.255.
Axiometric Gateway Guide MeshPlus™ damaged or removed, the mesh network will automatically fail-over to any available alternate Gateway 2. The secondary Gateway 2 should be deployed with identical mesh communication parameters (sync word, encryption key). 5. Gateway Replacement When a Gateway 2 fails or needs to be replaced for service, the following steps should be taken to ensure successful replacement: 1. 2. 3. 4. 5.
Axiometric Gateway Guide MeshPlus™ 7. United States of America, FCC: The Gateway 2 contains a radio frequency transceiver. Operation of the Gateway 2 in the United States is governed by the rules and regulations of the Federal Communications Commission (FCC).
Axiometric Gateway Guide MeshPlus™ Canada, Industry Canada: The installer of this radio equipment must ensure that the antenna is located or pointed such that it does not emit RF field in excess of Health Canada limits for the general population; consult Safety Code 6, obtainable from Health Canada’s website www.hc-sc.gc.ca/rpb 8. Troubleshooting a) External Power Disconnect external power Unscrew the four bolts that fasten the chassis front panel Remove the front panel.
Axiometric Gateway Guide MeshPlus™ The LED indicators for the MeshStamp should illuminate periodically (at least once per minute) A properly qualified technician should check the lithium battery voltage. A battery with a nominal voltage less than 3.4vdc should be replaced.
