2. Introduction
PX Serial is a one-port RS232/422/485 to Redundant Ethernet device server. PX
Serial can be configured by a web browser in https, or SSH console. Additional
management features include SNMP support and email alerts.
2.1 Integration into KVM.net
PX Serial can be integrated in the KVM.net system and managed by the KVM.net.
KVM.net is a robust central management appliance that provides reliable and secure
management of KVM IP devices.
KVM.net integrates with KVM IP devices to facilitate an intuitively manageable,
centralized out-of-band access portal - designed to maintain all IT assets. LDAP
based KVM.net centralizes all user account information relevant for IP device
administration without interfering in the stand-alone survivability of each device.
Designed to work across LAN or WAN, KVM.net, monitors and auto configures
KVM IP devices whether residing on t he local enterprise network or in remote
branches.
KVM.net delivers the most advanced solution for enterprise IT management and
remote control. It supports hundreds of servers in an environment that is completely
configurable by the network administrator.
Section 16 on page 23 explains how to integrate the PX Serial in the KVM.net
system.

6. Mounting the PX Serial
Wall mounting
Use the supplied screws to mount the ears on a wall.
Din-rail mounting
Screw the din-rail Mounting clips to the PX ears and mount on a din-rail.
7. Connecting the PX Serial
Connect the PX Serial to the power supply, the Network switch and Serial device as
explained below.
7.1 Connecting the Power supply
You can connect the PX Serial to the Power supply using the Terminal Block
(PWR1) and/or the Power Jack (PWR2). If both power inputs are connected, the PX
Serial is powered from the highest connected voltage. The PX Serial will only send a
loss of power alarm when power fails at both PWR1 and PWR2.

USER GUIDE

7.1.1 Terminal Block (PWR1)
1. Insert the positive and negative wires of your DC supply into the V+ and V-
contacts of the terminal block connector – see below.
(GND / V- / V+)
2. Tighten the terminal screws to prevent the DC wires from coming loose – see
below.
Once connected to the power supply, Power 1 LED turns red to show unit booting
up. When the unit is ready and if the IP setting is running correctly, the LED turns
green.
7.1.2 Power Jack (PWR2)
Connect the supplied 12VDC power adapter, or 24VDC power input to the power
jack. Power 2 LED turns red to show unit booting up. When the unit is ready and if
the IP setting is running correctly the LED turns green.
7.2 Connecting to the network switch
Connect the PX Serial to the network switch via the LAN 1 or LAN 2 port using a
standard 10/100M Ethernet cable. The Ethernet interface supports auto MDI/MDIX.
The relevant LAN 1 or LAN 2 LED turns orange for 10M Ethernet or green for
100M Ethernet.
Both Ethernet ports 1 and 2 can be connected to different switches. If both ports are
connected when the device starts up then Ethernet port 1 is the master and Ethernet
port 2 is the backup. But if when the device starts up only Ethernet port 2 is
connected, then Ethernet port 2 remains the master port.

7.4 Configuring the dipswitches
The Long-Range Termination dipswitches can configure 120 Ohm termination for
RS422 / 4-wire RS485 / 2-wire RS485. Set the dipswitches according to the
following table.
Dipswitch 1
Dipswitch 2
Configuration
ON ON 120 Ohm terminator for long distance 4-wire RS485 / RS422
ON OFF Don’t use this setting - it will cause errors!
OFF ON 120 Ohm termination for long distance 2-wire RS485
OFF OFF (Default) No termination for RS232/422/485 (short distance)
8. Restoring the default settings
To restore the default settings of the PX Serial press the Reset button – see Figure 1
- for 10 seconds. Release after the Power LED blinks red. All values are restored to
their defaults including the IP address (192.168.10.2), and password protection (if
activated) is removed. When the Power LED turns green, the device is ready to
function.

Click Service Mode, the following appears.
Figure 9 Service Mode
In TCP Server mode, you must define the available port number, idle timeout, alive
check, and maximum number (between 1 and 5) of simultaneous connections
allowed to the web configuration pages.
Idle Timeout: When the serial port stops data transmission for a defined period of
time (Idle Timeout), the connection will close and the port is free to try
connecting with other hosts. Zero disables this setting (default).
Alive Check: The PX device sends a TCP package at each defined time interval
(Alive Check) to the remote host to test the TCP connection. If the TCP
connection is dead, the connection closes and the port is free for other hosts.
Zero, disables this setting (default).
