The LanMaster 35 is a new handheld tester used for installing and maintaining Local Area Networks (LAN) using Power over Ethernet (PoE). The LanMaster 35 Power and Link Tester conducts power tests with actual loads to ensure that when a powered device such as a VoIP phone, wireless access point or security camera is connected to the network it will operate properly. The LanMaster 35 identifies whether power is IEEE 802.3af compliant or a legacy configuration, such as Cisco Inline power, for correctly connecting powered devices. The unit measures Loop Resistance to quickly identify damaged cables and bad punchdowns that cause intermittent problems or equipment malfunction. The LanMaster 35 provides Link speed and duplex mode testing capabilities for verifying connectivity of a powered or unpowered 10/100/1000BaseTX Link. The unit measures cable length and can be connected to a wall outlet to identify a connected port on a switch or hub. The LanMaster 35 is an essential tool for installing and maintaining networks that utilize the latest PoE (Power over Ethernet) technology.
