### 6. Installation & Setup

System Requirements:
- Windows NT/2000/XP operating system for driver installation
- Ethernet network connection (UTP/BNC/AUI)
- Terminal software (for initial console configuration)
- Administrative access for driver installation and network configuration

Installation Steps:

A. Windows Driver Installation
1. Obtain the Windows driver ZIP file from the supplier.
2. Create a directory on the Windows system for the driver files.
3. Unzip the contents of the ZIP file into the directory.
4. Run `setup.exe` to install the driver.
5. After installation, the utility `gport_ap.exe` becomes available for COM port mapping.

B. Configuring GTS for Windows Driver Operation
1. Set all serial ports to operate in RTTY mode:
```
set mode rtty all
save all
```
2. This enables compatibility with the Windows driver and virtual COM port mapping.

C. COM Port Mapping in Windows
1. Launch `gport_ap.exe` to open the COM port mapping interface.
2. Assign the GTS IP address and corresponding serial port numbers (1–16) to virtual COM ports.
3. Save the configuration and reboot the Windows system.
4. The mapped COM ports will now appear as standard serial ports in Windows.

D. Initial IP Address Configuration (Local Console Mode)
1. Connect a terminal to serial port 1 using 9600 bps, no parity, 8 data bits, 1 stop bit.
2. Power on the GTS586T. When LEDs 9–16 illuminate, press the INT button on the front panel to enter console mode.
- For LCD versions, use the “→” key on the LCD panel instead of the INT button.
3. At the console prompt, type `?` to display available commands.
4. Enter `sysconfig reinit` to enter initialization mode.
5. Use the `ifconfig` command to assign an IP address and select the Ethernet connector type (UTP/BNC/AUI).
6. Save the configuration and reboot to apply the settings.

E. Remote Configuration (Telnet Mode)
1. Once the IP address is known, connect to the GTS via Telnet.
2. Log in using the default password: `root`.
3. Use `?` to list available commands.
4. Configure serial port parameters and system settings as required.
5. Execute `save all` to store the configuration for future sessions.
6. Note: Initialization mode (`sysconfig reinit`) is not available in remote console mode.
7. The Telnet session will automatically terminate after a period of inactivity to conserve system resources.
