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
