The Suprex
®
RS-485 SPX-7500 series makes it possible to install card readers far from the access control panel, by
providing a two-wire RS-485 link between the door or gate readers, and most manufacturers’ panels. The Suprex®
includes both a Remote (door/gate) unit and a Central (Controller) unit. Optional repeaters and extenders are also
available. The SPX-7500 series devices are compatible with the EXP-2000 expansion modules.
