Installation

Follow these steps to install the KVM switch:

1. Ensure that power is turned off or disconnected from the unit and all connected computers.
2. Use a DisplayPort (DP) cable to connect the DP output port from each computer to the corresponding DP IN ports of the KVM unit.
3. Use a USB cable (Type-A to Type-B) to connect a USB port on each computer to the respective USB IN ports on the KVM unit.
4. Optionally, connect a stereo audio cable (3.5mm to 3.5mm) from the computer's audio output to the KVM unit's AUDIO IN ports.
5. Connect a monitor to the KVM unit's DP OUT console port using a DP cable.
6. Connect a USB keyboard and mouse to the two USB console ports on the KVM unit.
7. Optionally, connect stereo speakers to the AUDIO OUT port of the KVM unit.
8. Finally, power on the KVM by connecting the 12VDC power supply to the power connector, and then turn on all the computers.

Note: The number of computers that can be connected depends on the KVM model: up to 2 computers for a 2-port KVM, up to 4 for a 4-port KVM, and up to 8 for an 8-port KVM.

Multi-Head Units Installation

For multi-head configurations (e.g., SM-EDPN-4Q), ensure all DP output ports from a single computer are connected to the corresponding DP IN ports for one channel on the KVM. The DP IN connectors for a single channel are typically arranged vertically.

Diagram Description: The installation diagram illustrates connecting computer workstations to the KVM switch. It shows multiple computers linked via DP, USB, and Audio cables to the KVM. A monitor, keyboard, and mouse are connected to the KVM's console ports. Color-coded lines represent different cable types: DP IN, DP OUT, USB IN, USB K/M OUT, USB 2.0 OUT, AUDIO IN, AUDIO OUT.

Multi-Head Diagram Description (SM-EDPN-4Q): This diagram shows a PC workstation with multiple DisplayPort outputs connecting to the KVM's DP IN ports, which are grouped into channels (A, B, C, D). The text clarifies that DP IN ports within a single row correspond to the same output channel.

EDID Management

EDID LEARN

The EDID (Extended Display Identification Data) for the monitor connected to the DP Out Port must be learned. This can be achieved in three ways:

1. Automatic learning occurs on boot-up for monitors connected to DP Out ports.
2. While the unit is running, learn EDID for all connected monitors using one of the following commands:
   • Hotkey: Press Ctrl + Ctrl + e then Enter.
   • RS232: Send command //e followed by Enter.
3. While the unit is running, learn EDID for an individual monitor using one of the following commands:
   • Hotkey: Press Ctrl + Ctrl + e + [port number 1-4] then Enter.
   • RS232: Send command //e [port number 1-4] followed by Enter.

EDID LOCK

Once EDID is learned, it can be locked to prevent re-learning on boot-up or via EDID learn commands.

1. To lock EDID for all connected monitors:
   • Hotkey: Press Ctrl + Ctrl + l then Enter.
   • RS232: Send command //l followed by Enter.
2. To lock EDID for an individual monitor:
   • Hotkey: Press Ctrl + Ctrl + l + [port number 1-4] then Enter.
   • RS232: Send command //l [port number 1-4] followed by Enter.

Note: To remove an EDID lock, factory restore the unit using the factory restore commands:

• Hotkey: Press Ctrl + Ctrl + f then Enter.
• RS232: Send command //f followed by Enter.

Important Note: After learning EDID, it is recommended to use the Hotplug command:

• Hotkey: Press Ctrl + Ctrl + h then Enter.
• RS232: Send command //h followed by Enter.

System Operation

The SM-EDPN KVM switch can be controlled using three methods:

• Keyboard Hotkeys
• RS-232 Serial Commands
• Front Panel Buttons

All control modes allow users to configure the KVM to their desired settings.

Front Panel Control

Front panel buttons function as typical KVM switches. To switch to an input port, press the corresponding button on the front panel. The LED indicator for the selected port will illuminate.

The number of buttons varies from 2 to 8, depending on the specific model.

An EDID Learn function can be triggered from the front panel by holding down the first and last port selection buttons simultaneously for 3 seconds.

Hotkey and RS232 Serial Control

The SM-EDPN can also be controlled via RS-232 commands. Use a terminal application like HyperTerminal with the following settings:

• Baudrate: 115200
• Data Bits: 8
• Parity: None
• Stop Bits: 1
• Flow Control: None

Upon connecting via serial, the SM-EDPN information will be displayed when the device starts up.

Available Commands:

Custom Hotkey Triggers

Users can customize the keys used to trigger hotkey functions. The default trigger is Ctrl + Ctrl. The trigger can be changed to use keys such as Ctrl (Left/Right), Alt, Shift (Left/Right), Caps Lock, Scroll Lock, or F1-F12.

To View Hotkey Trigger Setting:

Use the RS-232 command: //?/? followed by Enter to view the current hotkey trigger settings. To reset the hotkey trigger, use the "Factory Defaults" command.

To Change the Hotkey Trigger Setting:

The format is: Hotkey + Hotkey + x + [desired hotkey]. For example, to change the trigger from Shift to Scroll Lock, the command would be Shift + Shift + x + Scroll Lock.

LED's Behavior

User Console Interface – Display LED:

Front Panel – Port Selection LED's:

IMPORTANT!

If all Front Panel LEDs are on and not flashing, the POWER UP SELF TEST has failed, disabling all functions. Check if any front panel port selection buttons are jammed. If so, release the jammed button and recycle power. If the issue persists, contact SmartAVI technical support at support@smartavi.com.

EDID Learn - Front Panel LED's:

All LEDs turn on for 1 second. Then:

• Port 1 LED flashes until the process ends.
• Port 2 LED flashes until the process ends if a second video board exists (Dual-head KVM).
• Port 3 LED flashes until the process ends if a third video board exists (Quad-head KVM).
• Port 4 LED flashes until the process ends if a fourth video board exists (Quad-head KVM).
