Interface Setup
Installing the VISA Library
VISA (Virtual Instrument Software Architecture) is a specication for standard soft-
ware that is used to connect instruments. VISA was dened by the IVI Foundation.
A VISA library is required to use the software application. The VISA library (NI-VISA,
Keysight VISA, or KI-VISA) must be installed on the controller (Windows).
One of the VISA libraries (driver software implemented in compliance with the VISA
specications) below is necessary.
• NI-VISA by National Instruments (Ver. 5.1.1 or later)
• Keysight VISA by Keysight Technologies (Keysight IO Libraries Suite16.0 or later)
• KI-VISA Ver. 5.0.4 or later
- Note -
If your VISA library is an older version than that specied, you may not be able to
use it depending on the interface.

KIKUSUI Electronics Corp. 18
Interface Setup
The PMX is equipped with LAN, RS232C, and USB interfaces as standard.
■PMX-A
The LAN interface complies with LXI Device Specication 2011 Rev1.4 Class C
and supports the VXI-11, HiSLIP, and SCPI-RAW protocols.
The USB interface complies with USBTMC device class.
By factory default, the remote control interface is set to the LAN interface. The LAN,
RS232C, and USB interfaces cannot be used simultaneously.
■PMX-Multi
The LAN interface complies with LXI Device Specication 2016 Rev1.5 and sup-
ports the VXI-11, HiSLIP, SCPI-RAW, and SCPI-Telnet protocols.
The USB interface complies with USBTMC device class.
There is no need to switch interfaces. All interfaces can be used simultaneously.
All Interfaces can be set to OFF in CONFIG settings.

RS232C
■RS232C connection
The RS232C connector on the PMX is a D-Sub 9 pin connector. Check that the
PMX and your PC are o󰀨 before connecting them.
The RS232C port of this product comes with a cover. Remove the cover to use the
port. Store the cover in a safe place so that you can use it to cover the RS232C
port when the port is no longer in use. For safety reasons, when not using the
RS232C port, be sure to attach to cover.
Use a D-sub 9-pin female-to-female AT type crossover cable for the RS232C cable.
The PMX does not use hardware handshaking (See Example 2 below).
Figure shows the connector pin assignments.
