Altronix Pace1KL is a SPE (Single Pair Ethernet) media converter/adaptor that enables connecting 10Base-T1L, IEE802.3cg compliant devices such as Security/Industrial/BMS/ Elevators/HVAC Controllers and sensors, etc. to an Ethernet network. Long distance headend to remote-end device cabling can be achieved to over 1km (1,000m, 3,280 ft.). In addition to new SPE (UTP) Ethernet network installations, upgrading of legacy networks, i.e. LONworks, RS485, 4-20mA Control Loops, etc. can be achieved by using the existing two wire cabling, thus saving rip-out & reinstallation costs. Operationally, the Pace1KL is connected to a POE midspan/endspan switch at the headend and passes network data from the switch via UTP up to 1km (1,000m, 3,280 ft.) to the remote T1L device.
