Terminology

Terminology Description
ATEN Controller, controller	ATEN Controller or controller refers to all models of ATEN Control Box and ATEN Control Pad.
Project A project is a set of configurations for an ATEN Control System, including configurations of one or more controllers and managed devices.

Overview

The RS-232/Contact to USB Keyboard Converter (VK211) makes remote control possible for PC-based devices or KVM switches (that do not have remote control capabilities) by converting control signals to full-range USB keyboard signals. With an RS-232 serial port on the controller, you can remotely perform control actions (using CLI commands) from the controller's supported interface, such as an ATEN Viewer; Through a contact in port on the controller, you can configure and store up to 4 presets (actions) to the converter, which you can execute from the converter.

In cases of urgent needs for local control, you can enable the priority mode to disable remote control. LEDs are built in on the top panel to instant and convenient viewing of the status of digital input signals, priority control, and power.

With the capabilities of emulating USB keyboard signals, the VK211 is an ideal solution for providing RS-232 / Contact In interfaces for KVMs or any PC-based devices that do not have remote control functionalities. Its compact size and non-power source design are suitable for applications such as factory production lines, control rooms, or any facility that requires automation with control system and remote secure operation without installing any software.

Features

• Converts RS-232 to full-range USB keyboard signals for remote control of USB keyboard-based devices such as KVMs and PCs
  ◆ Recalls the stored key codes and allows storage of up to 4 preset actions triggered via Contact In signals
  ◆ Local USB console ports for keyboard / mouse connection
• On-panel priority control push button for local operators to manage remote access in case of emergencies
• LEDs indicate the status of digital input signals, priority control, and power at a glance
• No extra power required by utilizing the connection with USB devices
  Learn mode eases the setup procedure and configurations
  ◆ Compatible with ATEN KVMs

Overview

This chapter provides recommended procedure and required information on setting up

Remote Control through Contact In

With the contact in port wired and connected to the controller (page 5), you can store up to 4 sequences of keystrokes (presets) and trigger the sequences from a keypad or a software control interface. To configure and store these sequences, use the priority button on the VK211 panel or remotely with CLI commands.

Configuring Presets with Learning Mode

To set up a preset with the priority button:

1. Select a preset.

a) Press and hold the priority button for about 3 seconds until preset 1 LED blinks to enable learning mode.
b) To configure preset 1, continue to the next step; to select another preset, press the priority button to cycle through the presets. A preset LED blinks to indicate that it is selected.

1. Perform the control action(s) on the local keyboard.

Note: The converter exits learning mode if no input is received within 5 seconds.

1. Press the priority button to finish learning. The preset LED dims.

Configuring Presets through CLI Commands

To set up a preset remotely with CLI commands, refer to the next section on how to create an RS-232 session (page 8) and the command syntax for configuring contact in ports (page 10).

Remote Control through RS-232

Through RS-232 serial connection between your ATEN or third-party controller (page 5), you can set up control actions using CLI commands. Refer to the user manual of your chosen controller for details on where to enter these commands.
