Watch the car position, door tachometer, and brake current in live graphs. The PC screen allows multi-track plotting—essential for diagnosing intermittent "door reopen" faults.

You will need a USB-to-RS232 or a specialized OTIS communication cable to connect the PC to the controller (e.g., MCS 220, MCS 310, or Skyrise controllers). emulator service tool otis on pc top
You cannot plug a standard USB cable directly into an Otis controller. To connect your PC emulator to the elevator, you must bridge the hardware gap using specific converters. The USB-to-RS422/RS485 Converter
You have two legal pathways:
Full access to all menus (e.g., SETUP , DIAGNOSTIC , TEST ).
The physical Otis Service Tool acts as a terminal interface. It communicates via a proprietary serial protocol to the elevator's main control board (such as the RCB_II, LCB_II, or GECB). The tool does not perform the calculations itself; it simply displays menus and accepts keystrokes to change parameters, view faults, and monitor inputs/outputs.

Often compatible with MCS, Lambda, and GECB systems. 💻 Hardware & Connection Requirements
Before plugging in your interface cable, install the latest virtual COM port (VCP) drivers for your USB-to-Serial adapter. This ensures your Windows PC recognizes the hardware interface accurately. Step 2: Configure the COM Port Open the Windows . Locate Ports (COM & LPT) . Note the designated COM Port number (e.g., COM3 ). You will need a USB-to-RS232 or a specialized
