LAN Interface
The LAN interface can control the number of devices with high
speed, and it's theoretical controllable maximum number is
to be calculated by approximately 4.2 billion. (The maximum
transmission speed varies by the number of connected devices)
In accordance with its applied standard, it is possible to
combine the device that is to control or to be controlled, it is also
the feature that it can be used with various applications. Also, in
computers installed with Apple Bonjour, it is possible to access
with a host name instead of the IP address.
l
AUTO MDIX function:
The PWX series can automatically identify the type
of LAN cable whether straight or cross is connected and it connects using the
appropriate method.
n
USB Interface
The USB interface has a feature of high versatility, and the ease
of a setup. The automatic recognition by the plug and play
releases a user from the complex setting operation under the
digital control, and it can be suitable interface when control by 1:1.
In accordance with the standard, the maximum number of the
connected devices can be configured up to 127 units. Moreover,
the USB interface of the PWX series complies to USB2.0, and it
has realized transmission speed of a maximum of 12 Mbps (es)
(Full Speed).
Equipped with standard LAN interface and optional VMCB function to support network-based remote control and monitoring
l
Basic configuration with LAN interface and VMCB (example)
As shown in the figure below, it is possible to connect a PC and
the PWX series with a hub to create a virtual group using a LAN
connection. A maximum of 255 virtual groups can be set, and
the maximum number of units can be configured up to 31 units
per group. A group can have a mixture of models.
The PWX series is equipped with LAN, USB, and RS232C interfaces
as standard features. By using the feature of virtual multi-channel
bus (VMCB), it allows you to control remotely and monitoring for
1-to-N as well as N-to-M for large-scale networks. In particular,
the LAN interface is LXI compliant
*1
, enabling you to easily
control and monitor the power supply through a browser on a
PC, smartphone, or tablet by accessing the web server built into
the PWX series .
Additionally, the optional application software, Wavy for PWX
(SD013-PWX), sequence creation and control software, allows you
to change settings for specific channels (in individual) on VMCB-
connected PWX series power supplies, and lets you perform
batch control using global commands

. You can also turn the
output ON and OFF on multiple units and adjust the output
voltage and current.

This function is expected for the PWX750ML in firmware version 2.0 and later.

:
This is only enabled for “Direct control” on Wavy for PWX. Global commands
that can be also used under control with VXI-11, HiSLIP, and SCPI-RAW.
l
Security for LAN connections
Access to the built-in web server can be restricted with a password. Also, when using VXI-11, HiSLIP, and SCPI-RAW for control, host restrictions can be
set with the IP address. It is possible to prevent access from any terminal other than the ones registered as a host (up to 4 hosts can be registered).
