Comnet EXP100 Central Unit - expansion module - RS-485 - RS-485

When used with the FDW1000 series of fiber optic Wiegand extender modules, the ComNet EXP100 Expansion Module enables additional Wiegand, Magstripe, or F/2F-based control panels, readers, and associated door/gate hardware to be added to the network. The 2-wire RS-485 data interface between the expansion modules provides a secure and completely supervised connection, with excellent immunity to electrical noise and interference. Up to 8 EXP100s can be used in a drop-and-repeat/daisy-chain topology, and each EXP100 may be set to a unique address (1 thru 15) via DIP-switch selection. An auxiliary I/O (input/output) interface is available for ascertaining door, gate, and control panel status and signaling, and a relay interface provides the door strike or gate activation functions. These units are designed for long-term, reliable operation in harsh industrial environments, and a fault-specific LED indicator is provided for rapidly ascertaining the operating status of the expansion module and the link. Packaged in rugged aluminum housing, the EXP100 is designed for shelf or surface mounting. The EXP100 is supplied as a matched set; a remote unit for door or gate locations, and a central unit for control panel installation.
