Overview

The VM0202H / VM0202HB's can be configured and controlled via RS-232 commands when connected to a host computer or other device, such as a control system. This chapter provides information on how to connect to the VM0202H / VM0202HB via RS-232/Telnet and command syntax.

Connecting to the Matrix Switch via RS-232

You can control and operate the VM0202H / VM0202HB using a high-end controller or PC. To connect to the VM0202H / VM0202HB via RS-232, do the following:

1. Connect the RS-232 serial port on the VM0202H / VM0202HB to the RS-232 serial port on your computer using a 9-wire straight cable, with only pin 2 to pin 2, pin 3 to pin 3, and pin 5 to pin 5 connected.

Pin Description
1 Not connected
2	RXD
3	TXD
4 Not connected
5	GND
6 Not connected
7 Not connected
8 Not connected
9 Not connected

1. The controller's serial port should be configured as follows:

RS-232 Protocol
Baud Rate 19200
Data Bits 8
Parity None
Stop Bits 1
Flow Control None

1. When a session is established with the VM0202H / VM0202HB, you can control and configure the VM0202H / VM0202HB via RS-232 commands. For more information on commands, see Commands, page 23.

Command Verification

After entering a command, a verification message appears at the end of the command line as follows:

• Command OK - indicates that the command is correct and successfully performed by the switch
• Command incorrect - indicates that the command has the wrong format and/or values.

Commands

After connecting to the VM0202H / VM0202HB via Telnet or RS-232, you can operate the system using the following commands.

Switch Port Command

The Switch Port command allows you to switch ports on the VM0202H / VM0202HB.

The formula for the Switch command is as follows:

$$ \text { Command } + \text { Input } + \text { Number } + \text { Output } + \text { Number } + \text { Control } + [ \text { Enter } ] $$

1. For example, to switch input port 02 (audio and video) to output port 01, type:

$$ \text { sw i02 o01 [Enter] } $$

1. To turn off video and audio output on port 02, type:

$$ \text { sw o02 off [Enter] } $$

1. To switch the next output to port 02, type:

$$ \mathbf {s w} \quad \mathbf {i 0 2} + [ \text { Enter } ] $$

The following tables show the possible values for the Switch Port command:

Command Description
sw Switch command
Input Command Description
i Input command
Port number Description
xx 01-02 port (default is 01)
Output Command Description
o Output command
Port number Description
yy 01-02 port (default is 01)
* All output ports
Control Description
on Turn on the display
off Turn off the display
+	N	e x
- Previous Port

Note: 1. By default, input port 01 is tied to output port 01; input port 02 is tied to output port 02 (i.e., o01 i01, o02 i02).

1. Each command string can be separated with a space.

2. The Port Number can be skipped, and the default value will be used.

3. For this Switch Port Command to work, remember to enable the Panel Button Control function, see Panel Button Control Commands, page 32.

The following table lists the available Switch Port commands:

Command	Input Command	Input Port	Output Command	Output Port	Control	Enter Description

The Firmware Upgrade Utility

Introduction

The purpose of the Windows-based Firmware Upgrade Utility is to provide an easy process for upgrading the VM0202H / VM0202HB. The program comes as part of a Firmware Upgrade Package that is specific for each device.

As new firmware versions become available, new firmware upgrade packages are posted on our website. Check the website regularly to find the latest information and packages.

Downloading the Firmware Upgrade Package

To download the firmware upgrade package:

1. On our Website go to: Download - Firmware and choose the device model, or from the VM0202H / VM0202HB product page under the Resources tab, select Firmware. A list of available firmware upgrade packages appears.

2. Choose the firmware upgrade package that you wish to install (usually the most recent) and download it to your computer.

Preparation

To prepare for the firmware upgrade, do the following:

1. Use a Micro USB Type-B cable to connect a USB port on your computer to the firmware upgrade port of your VM0202H / VM0202HB.

VM0202H

VM0202HB

1. Unplug the VM0202H / VM0202HB's power adapter.
2. Power on the VM0202H / VM0202HB.

a) To power on the VM0202H, plug the power adapter to the power jack located on the rear panel, and press the power pushbutton located on the front panel.

1. To power on the VM0202HB, plug the power adapter to the power jack located on the rear panel.
2. You can start the upgrade process as explained on the next page.

Starting the Upgrade

To upgrade the firmware:

1. Run the downloaded firmware upgrade package file either by double-clicking the file icon.

The Firmware Upgrade Utility welcome screen appears:

1. After the upgrade is complete, a successful message appear:

1. Now you can power off the VM0202H / VM0202HB, then power it back on again.

Upgrade Failed

If the Upgrade Succeeded screen doesn't appear, it means that the upgrade failed to complete successfully. See the next section, Firmware Upgrade Recovery, for how to proceed.

Firmware Upgrade Recovery

There are three conditions that call for firmware upgrade recovery:

• When a firmware upgrade is manually aborted.
• When the mainboard firmware upgrade fails.
• When the I/O firmware upgrade fails.

To perform a firmware upgrade recovery, do the following:

1. Power off the device.
2. Connect the Micro USB Type-B cable to the firmware upgrade port.
3. Repeat the upgrade procedure.

Rack Mounting

• Before working on the rack, make sure that the stabilizers are secured to the rack, extended to the floor, and that the full weight of the rack rests on the floor. Install front and side stabilizers on a single rack or front stabilizers for joined multiple racks before working on the rack.
• Always load the rack from the bottom up, and load the heaviest item in the rack first.
• Make sure that the rack is level and stable before extending a device from the rack.
• Use caution when pressing the device rail release latches and sliding a device into or out of a rack; the slide rails can pinch your fingers.
• After a device is inserted into the rack, carefully extend the rail into a locking position, and then slide the device into the rack.
• Do not overload the AC supply branch circuit that provides power to the rack. The total rack load should not exceed 80 percent of the branch circuit rating.
• Make sure that all equipment used on the rack – including power strips and other electrical connectors – is properly grounded.
• Ensure that proper airflow is provided to devices in the rack.
• Ensure that the operating ambient temperature of the rack environment does not exceed the maximum ambient temperature specified for the equipment by the manufacturer.
