4.6 Access Control 4.7 Security 4.8 WDS 4.9 DHCP Server 4.10 Stations 4.11 Save Configuration - Template 4.12 Help Chapter 5: Troubleshooting 5.1 No Page Displayed When Accessing the Web-based Utility This is either because the radio is extremely busy on the RF side or because the Ethernet connection is problematic. Try hitting the “Refresh” or “Reload” button of the Web browser a few times. If the same message persists, it is unlikely that the problem is caused by a busy radio. Check your Ethernet connection. Make sure you use at least a legitimate CAT-5 cable. Make sure that it is a straight-through cable between the radio and the computer, or a crossover cable between the radio and the hub, if a hub is involved. Check to make sure that the Ethernet card of the computer running the Web- based Utility program is functional and has a correct IP address and subnet mask setting. 5.2 No Radio Link Check the following possible causes: • Make sure that the target radio, the Station, is turned on and operating properly. • Make sure that the “Signal Strength” indicator on the target Station radio’s utility program is not zero. A minimum of 70% is recommended. If the “Signal Strength” is less than 70%, the distance between the Trimar-AP and the targeted Station radio may be too far. Decrease the distance to see if the radio link can be established. • Make sure that the target Station radio’s SSID is blank or the same as that for the Trimar-AP Access Point. • If the WPA is turned on, make sure that the entire chain of necessary configuration from the host supplicant to the RADIUS is properly configured. If you only turned on WEP and/or 802.1X, again make sure that all the necessary configuration is correct. • For troubleshooting purposes, turn off all the security settings and see if the station radio and the AP can be linked. • Make sure that the target Station radio’s MAC address is added to the “Allowed Station List” if this feature on Trimar-AP is turned on. • Make sure that there is no RF interference present in the radio network. 5.3 No Network Connection While the Radio Link is Good If the target Station radio’s utility indicates good “link quality” with Trimar-AP, but the host computer/device cannot be connected to the network • Make sure that the Yellow LED on the radio is NOT constantly ON. If it is, Ethernet connection is questionable. • Make sure the Ethernet Adapter of the host computer/device is properly installed. • Make sure that the UTP cable connecting the Trimar-AP radio and the network equipment (switch or router) meets at least the CAT-5 standard and has the correct straight-through or cross-over connection. Perform similar checks of the Ethernet cable connection of the target Station radio to its host device. • Make sure that the IP address of the host computer/device connected to the target Station radio is properly set up for the network. 5.4 Poor Link Quality If the “Signal Strength” is reasonably high (>70%) and the “Link Quality” is not zero, but the “Link Quality” stays in the Poor range, it could be due to one of the following reasons: • Make sure that radio interference is not present in the radio network. • Make sure that the radio is not surrounded by many strongly reflecting (metallic) surfaces. With multiple reflecting surfaces between the radio in question and the target radio, a severe “multi-path” problem may introduce high bit error rate despite a strong “Signal Strength”. • Make sure that there is not a condition of severe packet collision caused by a “hidden node” problem. A “hidden node” problem is the situation where the RF signal from two or more Station radios cannot reach each other (but can reach the AP). In such situation, multiple Stations may attempt to transmit data packet to the AP at the same time and therefore cause packet collision. To solve this problem, either re-arrange the Stations in question such that the RF signals are mutually sensible by all Stations, or turn-on the RTS/CTS protocol by setting the “RTS threshold ” on the “Config” tab to a reasonably small value (300, for example). There is no guarantee that the packet collision can be entirely eliminated by invoking RTS/CTS protocol, but the severity can be reduced enough to see visible improvement of the link quality. • Change “Burst time ” value to zero when signal strength is marginal or site survey detects other Access Points that are using the same channel or overlapping channels. Overlapping channels are current channel plus/minus four. Maximum number of none overlapping channel is 3 when channel 1, 6 and 11 is used. 5.5 Radio Interference You may be able to eliminate RF interference by trying the following: • Find the “channel” used by the source of the interference and coordinate your network and the interference source to be on channels that are at least 20MHz, but preferably 30MHz, apart. • Reseat the Trimar-AP radio to a location where the interference is minimized for all Station radios in the network. • Avoid using 2.4GHz cordless phone in the vicinity of the radio • Keep the computer with the Trimar-AP radio and its associated Station radios away from the microwave oven and large metal objects. • Consult the dealer or an experienced radio technician for help. 5.6 Settings Appear not to be Modified Check the version of the software to be upgraded and the software currently running in the Trimar-AP AP radio. If they are the same, you must click “Reset to factory defaults” button on index.html page to make software upgrading take effect. This upgrade effectively overwrites the current software with a different set of factory defaults. IMPORTANT: please save your configuration to template right after you have any change so that you can recover your settings. 5.7 Technical Support Please contact OTC Wireless for Technical Support.

Introduction This document attempts to prove the safety of radiation generated by RF devices to the human body. The limit for Maximum Permissible Exposure (MPE), specified in FCC 1.1210, is listed below. The power generated by this product is measured by a power meter. Through use of the Friis transmission formula and the maximum gain of the antenna, the distance from the product at which compliance with the MPE limit is achieved may be calculated. Alternatively, near field measurements may be performed to demonstrate compliance at a specific measurement distance. Near field probe: Wandel & Goltermann EMR-20. 2. RF Exposure Limit According to FCC 1.1310: the criteria listed in the following table shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation as specified in 1.1307(b).
