### 4. Functionality

The DMK585‑17 integrates display, keyboard, mouse, and KVM switching into a single 1U rackmount module. The operator can slide out the drawer, power on the console, and access up to eight connected servers through PS/2 and VGA interfaces. Switching between systems is achieved via:

- Front Panel Push Buttons for direct port selection.
- Keyboard Hotkeys (double “Scroll Lock” activation followed by numeric input).
- On‑Screen Display (OSD) menu for intuitive navigation, naming, and configuration.

The OSD supports up to eight‑character system names, password protection, and adjustable scan timing. The auto‑scan mode cycles through connected systems for monitoring purposes. The unit’s LED indicators show active ports and bank numbers, while an audible buzzer confirms switching actions.

Use Cases and Applications:
- Data centers and server farms requiring centralized management.
- Network operation centers (NOCs).
- Industrial control systems and test environments.
- IT maintenance racks and co‑location facilities.
- Secure server rooms where space and access control are critical.

Compatibility:
Supports standard PS/2 keyboard/mouse and VGA video interfaces. Compatible with major operating systems including DOS, Windows (3.x–XP), Windows NT, NetWare, SCO Unix, HP‑UX, and Linux distributions.

### 6. Installation & Setup

Pre‑Installation Requirements:
- Ensure all connected computers and peripherals are powered off.
- Verify sufficient rack space (1U height, 550 mm depth).
- Confirm cable lengths are adequate for server connections.

Installation Steps:
1. Mounting: Attach the provided brackets to the drawer sides and secure the unit into a standard 19‑inch rack.
2. Video Connection: Connect each server’s VGA output to the corresponding KVM port using HDDB 15 male‑to‑male cables.
3. Mouse Connection: Connect each server’s PS/2 mouse port to the KVM’s PS/2 mouse port.
4. Keyboard Connection: Connect each server’s PS/2 keyboard port to the KVM’s PS/2 keyboard port. Use AT‑to‑PS/2 adapters if necessary.
5. Power Connection: Attach the AC power cord to the rear power inlet and plug into a grounded outlet.
6. Verification: Power on the KVM; Port 1 LED should illuminate and an audible beep will confirm readiness.
7. Daisy‑Chaining (Optional): Connect additional KVM units via the daisy‑chain ports using the 3‑in‑1 cable kit. Up to eight levels can be chained, supporting 120 servers. For chains beyond five banks, use a VGA‑100 extender to maintain signal integrity.

Configuration:
- Access the OSD via hotkey (double “Scroll Lock” + Space bar).
- Assign system names, set scan intervals, and configure password protection.
- Default password: “00000000”.
