Elevator Access Control System Integration Diagram - Pegasus Solutions #237817 (License: Personal Use)

This technical diagram illustrates how a PC running PST-ADV-E-ELE software communicates with a lift control panel through various interface converters-including RS-232 (PC-R245T), TCP/IP (PC-T100), and USB/RS485 (PCT-UR5)-to enable access control using keypads, RFID cards, or fobs. The signal flows through the PG-OUTMOD-24A relay box, which manages output relays for door unlocking and elevator call functions. All components are part of a unified security and automation solution for modern elevators.

Used on product documentation, technical support pages, or sales collateral for elevator access control systems; targets engineers, integrators, and facility managers seeking interoperability between legacy and IP-based hardware.
