To control multiple computers, a KVM switch is required. Devices of this type differ in conductivity as well as inverter frequency. On average, the scanning process takes no more than 10 seconds.
Modern modifications are made with the option of quick connection. Sound messages are not supported by all switches. There are quite a few manufacturers of devices on the market. In order to determine the choice of model, you should consider the main types of devices.
Modifications to 2 ports
A 2-port KVM switch is typically sold with an operational converter. The threshold frequency level is not high. On average, equipment scan time takes about 12 seconds. There is a linear output for connecting a monitor . Nowadays, devices are sold with built-in amplifiers. A microcontroller is used to control the connections. In some models it works with a modulator. There is a good switch to two ports in the region of 3200 rubles.
Four Port Models
The four-port KVM switch is pretty much in demand. Many models are sold with a built-in amplifier. The threshold frequency of the converter is 150 Hz. On average, the signal conductivity does not exceed 4.5 microns. In this case, much depends on the type of modulator.
Devices with operational counterparts are quite expensive. Scanning equipment from them does not take much time. A coaxial output is provided for connecting audio equipment. There are also models with standard 3.5 mm jacks. There is a high-quality switch to 4 ports in the region of 3600 rubles.
Eight Port Devices
The 8-port KVM switch is in demand in large enterprises. Some models are made with hot plug function. They take about 6 seconds to scan devices. It is also important to note that the modulator in the devices is installed of various types.
If we consider pulse modifications, then the threshold frequency parameter fluctuates around 130 Hz. Models work through a power cable that connects to a 220 V network. You can buy a switch for 8 ports in the store at a price of 4,500 rubles.
Aten Model Features
The specified KVM switch is made with three line outputs. In total, the model has two connectors for the speaker system. If you believe the reviews of experts, the process of scanning equipment is very fast. If necessary, you can always use the hot plug option. The model has no automatic scanning system. There is no connector for speakers. It is also important to note that the model does not have access to a modem. A standard linear jack is used for the keyboard. The signal conductivity parameter at the switch is 4.6 microns.
If you believe the experts, the modulator is used with a good conductor. The converter in the model is provided without an amplifier. Microcontroller malfunctions are very rare. Problems scanning the console occur quite often. In terms of dimensions, the switch can hardly be called compact. There is no PC connector in this case. Thus, some monitors cannot be connected to the system. To do this, you will have to use a special adapter. It costs the specified switch as much as 3800 rubles.
D-Link Reviews
The D-Link KVM switch has many advantages. The main advantages of specialists include high signal conductivity. The threshold frequency of the converter is 130 Hz. In this case, the modulator uses a two-pin type. In total, the model has two connectors for a monitor. Line outputs on the panel are provided. There is no USB connector for peripherals.
If necessary, the modem is allowed to connect only through the adapter. Scanning time for new equipment is no more than 13 seconds. If you believe the experts, then failures in the microcontroller are rare. The display system of the model is standard. You can buy a switch in the store for 2800 rubles.
Planet IKVM-8000 Model Description
This is a simple and inexpensive KVM-DVI switch. The features of the model should also include compactness. For the monitor, it has two connectors. If necessary, the keyboard can be connected via a line output. In this case, the modulator uses a three-pin type. In total, the model has two connectors for the modem. There is no coaxial output on the device.
If you believe the experts, then failures in reading information are rare. It is also important to note that scan delays are minimal. The threshold frequency of the converter is 130 Hz. The switch operates from a network with a voltage of 220 V. The sound notification function of the model is not provided. The microcontroller for controlling personal computers is used without an amplifier. There is no panel output for the speaker system. This switch is on sale at a price of 3400 rubles.
Parameters of the Planet IKVM-8055 device
The specified KVM switch is based on a multi-channel modulator. The converter in this case is used with conductors. In total, the model has two connectors for monitors. According to experts, scanning new equipment does not take much time.
The microcontroller itself is matched with good signal conductivity. The threshold frequency of the switch is 4.4 microns. In this case, the permissible moisture level is 45%. There is no connector under the switch for the model. The price of this switch is approximately 3900 rubles.
Characteristics of the Planet IKVM-8090 model
This switch is sold on two ports. According to experts, the model is able to quickly read information about new equipment that is connected. Connectors for monitors are located next to the line outputs. In this case, there is no need to use adapters.
In total, the model has three coaxial connectors. There is a separate slot for the modem. If we talk about indicators, then the signal conductivity is 4.2 microns. In this case, the threshold frequency does not exceed 120 Hz. For dual port devices, this is considered normal. The user is able to buy the specified switch at a price of 2900 rubles.
Edimax EK-PAK2 Reviews
This is a very simple and inexpensive USB-KVM switch. In total, the user can find two ports on the panel. In this case, the modulator is applied pulse type. Thus, scanning new equipment does not take much time. If you believe the experts, then problems with signal interruption occur infrequently. The threshold frequency of the converter in the model does not exceed 130 Hz. The signal conductivity fluctuates around 2.3 microns.
It is also important to note that the model does not have a linear output for monitors. In this case, you will have to use an adapter. However, the model has coaxial connectors. Another device is capable of boasting a high-quality display system. The microcontroller is a contact type. Automatic scanning system is provided by the manufacturer.
However, there is no sound alert option. Permissible humidity level during equipment operation is 60%. The system is not suitable for connecting the switch. In this case, the hot plug option is missing. There is a KVM switch for 2 computers nowadays about 4200 rubles.
