Single port PS2 KVM over IP

This is an optionally available external module to switch power of a single system by putting it in the power supply line of the controlled system.

5.6.1 Modem Settings

PS/2 KVM over IP switch offers remote access using a telephone line in addition to the standard access over the built-in Ethernet adapter. The modem needs to be connected to PS/2 KVM over IP switch’s serial interface.

Logically, connecting to PS/2 KVM over IP switch using a telephone line means nothing else than building up a dedicated point to point connection from your console computer to the PS/2 KVM over IP switch. With other words, PS/2 KVM over IP switch acts as an Internet Service Provider (ISP) to which you can dial in. The connection is established using the Point-to-Point Protocol (PPP). Before you connect to PS/2 KVM over IP switch, make sure to configure your console computer accordingly. For instance on Windows based operating systems you can configure a dial-up network connection, which defaults to the right settings like PPP.

The Modem Settings panel allows you to configure the remote access to PS/2 KVM over IP switch using a modem. The meaning of each parameter will be described below. The modem settings are part of serial settings panel (Figure 5.15).

. Serial line speed

The speed PS/2 KVM over IP switch is communicating with the modem. Most of all modems available today will support the default value of 115200 bps. In case you are using an old modem and discovering problems try to lower this speed.

. Modem Init String

The initialization string used by PS/2 KVM over IP switch to initialize the modem. The default value will work with all modern standard modems directly connected to a telephone line. In case you have a special modem or the modem is connected to a local telephone switch that requires a special dial sequence in order to establish a connection to the public telephone network, you can change this setting by giving a new string. Refer to the modem’s manual about the AT command syntax.

. Modem sever IP address

This IP address will be assigned to the PS/2 KVM over IP switch itself during the PPP handshake. Since it is a point-to-point IP connection virtually every IP address is possible but you must make sure, it is not interfering with the IP settings of PS/2 KVM over IP switch and your console computer. The default value will work in most cases.

. Modem Client IP address

This IP address will be assigned to your console computer during the PPP handshake. Since it is a point-to-point IP connection virtually every IP address is possible but you must make sure, it is not interfering with the IP settings of PS/2 KVM over IP switch and your console computer. The default value will work in most cases.

5.7 User Settings

The PS/2 KVM over IP switch comes with 2 pre-configured user accounts that have fixed permissions. The account ’super’ has all possible rights to configure the device and to use all functions PS/2 KVM over IP switch offers. The account ’user’ has only the permission to open
