Travel Information Display Unit 
* Overview
When door open/close data and speed signals are inputted, the travel information display unit calculates the travel distance and indicates the traveling direction and status of the train.

Control System 
* Overview
This control system automatically controls the train information display unit and the destination/train number display unit that have been installed to provide better services for passengers.

* Functions
- Controls the train number display unit
- Controls the car information display unit.
- Controls the destination display units installed in the front and the side
Train Information Display Unit 
* Overview
The train information display unit receives display time and display message (stop and announcement) data from the control system and displays this data.

* Functions
- Displays the destination, announcement, stops, opening doors, and other information
Train Number Display Unit 
* Overview
The train number display unit interfaces with the control system that is separately equipped in the TC car for better services, and receives train number data from the TCMS through the control system to display it.

* Transmission Interface
- Transmission Method: RS-485 2 WIRE MULTI-DROP
- Transmission Speed: 9600BPS
Destination Display Unit 
* Overview
The destination display unit receives the destination code from the TCMS or that has been set in the control system, and displays it.

* Setup Method
- Automatic Setup: When the TCMS recognizes the destination code, the destination receives the corresponding destination code from the control system and displays it.
- Semi-automatic Setup: The destination display unit receives the destination code that has been setup in the control system and displays it.
Train Performance Monitoring System (TPMS)... 
* Overview
The TPMS has been applied to Line No. 2 and 3 of Seoul Metropolitan Subway to detect/monitor the GEC chopper device in general. The TPMS is a trouble detection device that analyzes train status and operation data when any trouble occurs in the train and monitors performance of the train.
* Major Features
  - Trouble record (50 times)
  - Data sampling time (2ms)
  - Fault data record upon troubles (Overload, VL O/L, IA O/L, IF O/L, Overheat, GPS fault)
  - Digital signal 42CH (Gate signals are analyzed.)
  - Operation data record (16Mbyte Memory - 170 hours)
  - Operation data analysis (Windows program)
  - Record data output (Using ground equipments)
  - Data transmission through communication
  - Train number and time setup
