1.5 Introduction

Mini-Circuits has developed two series of RF switch matrices, the RC-xxxxx-A18 series capable
of USB and Ethernet (HTTP and Telnet protocols) control and the USB-xxxxx-A18 series with
just USB control. Both series have SPDT and SP4T switches, like the one shown in Figure 1.
These switches operate from DC to 18 GHz; all are available in a variety of different
configurations with low insertion loss (0.2 dB typ.) and high isolation (85 dB typ). All models are
USB HID devices and are “plug & play,” with no driver installation needed. Ethernet control in
the RC-xxxxx-A18 series allows for both dynamic (DHCP) and static IP. Using the supplied GUI
software or most common lab test software you can easily set complex, timed switching
sequences using multiple switches with only a single power supply and USB control line, or
Ethernet. You can even synchronize other software with the switching sequence. These
USB/Ethernet RF switches are light, compact and greatly simplify setting up complex switching
sequences.

Using the Ethernet interface the switch matrices can be controlled from any computer with an
internet connection, or even your smartphone from almost anywhere!

1.6 Service and Calibration

The USB/Ethernet switch matrix models do not require any periodic service or calibration. The
only user service possible for the switch matrix models is external cleaning of the case and
connectors as needed. Do not use any detergents or spray cleaning solutions to clean the
Switch Matrix. To clean the connectors use an alcohol solution, and to clean the case a soft,
damp cloth.

3.2 Ethernet Interface

Mini-Circuits provides two Graphical User Interfaces for Ethernet (HTTP) control of the switch
matrix and one for Ethernet (Telnet). These interfaces allow you to control the switch matrix
remotely from almost any computer connected to a network, or even a smartphone. If the switch
matrix is connected to the same network as the computer or smartphone you wish to use to
control the switch matrix you can proceed directly to control it as detailed below. In order to
control the switch matrix over the internet you will first need to set up a Virtual Private
Network(VPN).

3.2.1 A basic GUI interface is programmed into each switch matrix, and can be

accessed simply by typing the switch matrix' IP address into the address window of most
common browsers (See Figure 3.1.1). This interface is usable from almost any Windows,
Mac or Linux computer.

Figure 3.2.1: Web-browser GUI Interface

3.2.2 A more sophisticated interface with options for setting up timed sequences

and running external programs at preselected times is available on the switch controller
program from the included CD. This program allows communication using either HTTP or
Telnet protocols as selected, but requires a Windows Operating system. For installation
instructions see chapter 1.

3.2.4 To start the program, go to the Start menu and select All Programs>Mini-

Circuits RF USB Switch Controller (default), or go to the other destination address you
selected earlier. The “Mini-Circuits RF USB Switch Controller” icon should be waiting there
for you. Click on it and get started!

3.2.4 The Switch Controller Startup screen will appear. For USB control see

section 3.1, for Ethernet control either type the IP address or click on the search icon next to
the IP address field.

Figure 3.2.4: Switch Controller Startup screen

Depending on the browser used and your network configuration you may need to disable

Note:

the proxy server for your computer, or add the switch matrix's IP address to the list of addresses
in the proxy server.

3.2.5 After clicking on the search icon The IP search will pop up with a list of

switch matrix IP addresses found and their HTTP ports on the left side of the screen, and full
details of each unit on the right. Mark the IP address you wish to use and click select. The
search window will close and the IP address will be entered in the IP address field of the
initial screen automatically.

Figure 3.2.5: Ethernet IP search window

Notes:

Note:

1) To refresh the list of units found click on the Search button.

2) The search function uses ports UDP 4950 and UDP 4951 for communication, ensure

your firewall allows access to these ports.

3.2.6 After entering the IP address enter your password if you set one (see section

3.1.7), select the communication protocol you wish to use (HTTP or Telnet) and click start,
the unit's main screen will open.

changing Ethernet settings is only possible via USB control, see section 3.1.7 for details.

3.2.7 Telnet or HTTP text commands can also be used to control the Switch matrix.

Just type in the command in the address field of your internet browser or implement a
Get/Post HTTP function in your selected application (for HTTP) or establish a telnet
connection(for Telnet). A full list of the commands available and their syntax is available
in Mini-Circuits programming handbook chapter 2, and in a text file on the CD provided
with the switch matrix, in the Ethernet directory.

3.3 Switch Configurations

Several different preset configurations are available in the Mini-Circuits GUI switch controller
and are described below. Where external RF cables are required for the configuration this is
noted and the placement of the RF cables shown in the configuration screen. These preset
configurations are currently available only via USB control for complex configurations with timing
considerations or setting configurations via Ethernet control see Section 3.4.

3.3.1 USB-1SPDT-A18 / RC-1SPDT-A18

These models have only a single absorptive SPDT switch, and thus there are no additional
configurations beyond that of an SPDT switch. The switch state can be changed either by
clicking on the button above the switch drawing circled in Fig. 3.3.1 (the button will change
between ‘COM->2’ and ‘COM->1’ to indicate the current switch state) or in the user

Notes:

1. Typical switching time is 25 mSec, attempting to toggle a given switch twice with too short a
delay between the commands may produce errors.

2. If time limit is set to a value which is not a multiple of sequence run time it will be rounded up
to nearest multiple.

3.4.2 User sequence graphical switch presentation

This window is opened beside the user sequence window by selecting the ‘View Switches’
option. This window shows the current state of all switches and allows you to illustrate multi
switch setups by ‘dragging’ one of the connector circles to another switch’s connector for
example 2(A) to COM(B) (see Fig. 3.4.2a).
Each connector can be connected to only one other connector and can not be connected to
another connector in the same switch. Adding a second line between switches to a
connector will erase the previous line and replace it with the new one.
Start and end of active signal paths are highlighted in the same color, with each signal path
using a different color while the inactive connectors will remain white.
Clicking on the tab of a connector allows you to type in a new name for the connector
instead of the default ‘1’, ‘COM’ or ‘2’.

3.5 Firmware update

3.5.1 Once the switch controller GUI is installed and started (see chapter 2) you

will note an (fw) indicator in the upper right corner of the main screen.

Figure 3.5.1 Firmware indicator on main screen

3.5.2 In order to update your switch matrix firmware, you must have a switch

matrix unit with firmware revision B3 or later and a Windows computer with Mini-Circuits’
Switch Controller software installed.

A power interrupt, to either the computer or the switch matrix while the firmware is being
updated may cause the firmware to be corrupted. It is therefore recommended to only
update the firmware while both the switch matrix and the computer are connected to an
Uninterruptable Power Supply (UPS).

3.5.3 Click on the ‘(fw)’ indicator, this will cause the firmware - info window to open

(See Fig. 3.3.3). The ‘Firmware’ listed is the version of the firmware installed in your switch
matrix. Click on “Update Firmware” to select a new firmware version to install or click ‘Exit’ to
close the firmware – info window.
