2 -About Mini-Circuits Solid-State Switch Modules
2.1. Introduction
Mini-Circuits has developed a series of solid-state USB/Ethernet RF switch modules in rugged, low-profile cases. Switch models
are available for a broad range of applications in frequencies from DC to 67 GHz, configurations from SPDT up to SP16T, and
multiple switches integrated within a single package. These models have been designed to combine the fast-switching speeds and
bullet-proof reliability of solid-state switches, with the exceptional isolation performance typically reserved only for mechanical
switches.
The daisy-chain control interface with “dynamic addressing” simplifies control integration, allowing multiple switches of various
types to be combined. Simply connect the devices via the serial interfaces and power on, and the whole chain of up to 25
compatible switches can be controlled independently through a single USB and software interface.
The switches can be controlled via the supplied GUI or with most common lab test software using the supplied API DLLs. In
addition, Mini-Circuits provides the command codes for direct USB control (see programming manual for details). TTL and I2C
control interfaces are available for some switch models.
2.2. Key Features
•Absorptive solid-state switches
•Wide frequency ranges
•High-speed switch transitions
•High reliability (no moving parts to wear out)
•High isolation
•High power handling (model dependent)
•Programmable with timed switching sequences
•USB HID (Human Interface Device) for “plug & play” operation (no driver installation required)
•Remote control via Ethernet protocols
•User-friendly graphical user interface (GUI) for Windows
•API DLL for Windows and direct USB programming support for Linux (see programming manual for details)
•DC can be supplied via the USB or serial control connectors (model dependent)

4 -Hardware Setup
4.1. USB Control
Connect the switch to the computer using the provided USB cable or equivalent one, and then connect the required RF
connections.
Caution
:
•Note the maximum input power rating in the datasheet and the conditions specified for it.
•Exceeding these values may damage the switch.
4.2. Ethernet Control (RCS series)
•Connect the unit to power source via a USB cable.
•Connect a standard network cable between the unit’s RJ45 socket and the network port.
•Ensure the network indicators on the unit’s RJ45 socket light up after a few seconds.
•Connect the unit’s input and output RF ports to your system.
4.3. TTL Control (USB-1SP16T-83H only)
The USB-1SP16T-83H TTL control interface consists of 5 unlatched parallel control bits that select the desired switch state (see
model datasheet for truth table). The parallel control does not have any latch and thus will respond immediately to any change.
Connecting the switch to USB control and establishing USB communication will disable the TTL control until the switch is reset by
disconnecting and then reconnecting power.
All TTL controls are connected with internal pull-down resistors, so the default state of the switch is in “disconnected” state.
The TTL interface is input only and does not provide feedback on switch state.
4.3.1. TTL Setup Instructions
•Connect the control lines (5 bits) to a suitable I/O controller.
•Connect 5V power either using a power adaptor such as USB-AC/DC-5+ connected to the USB port, or by supplying power to
pin #1 of the D-Sub connector.

AN-49-012 © 2023 Mini-Circuits
Rev. H | ECO-018898 | 21-Aug-2023Page 12
4.4. I2C Control (U2C series)
I2C is a short-range synchronous communication protocol for simple 2-wire communication with slave devices using clock (SCL)
and data (SDA) connections. The U2C models also include 3 address pins (A0, A1 and A2), allowing up to 8 switches to be controlled
independently from a single master with shared SDA and SCL connections.
All I2C pins are connected to an internal pullup resistor so will float to logic ‘1’ when disconnected. This sets a default address of
111 for all units (decimal 7). Addresses from 0 to 7 can be set by externally grounding the relevant address pins (A0, A1 and A2).
The I2C functionality is limited to setting or reading switch states. Control sequences are sent to the switch in several bytes on the
data connection, enclosed by a start and stop signal, and clocked at up to 400 kHz. The switch will acknowledge each byte received
with a single “ACK” bit (logic 1) on the same data connection.
To send a command to the switch 3 bytes will be sent:
•Control byte (1010A2A1A0R/W)
Where:
1010 = Control code for U2C models
A2A1A0= 3-bit address for the switch module
R/W = Read / write select bit (‘0’ to write or ‘1’ to read)
Example:
Control code = 1010
Address = 4 (decimal) = 100 (binary)
R/W = 0(write to switch)
Control byte = 10101000
•Switch selector byte – Currently all U2C models contain only a single switch so this byte is always 00000001.
•Switch state byte (00000XYZ) – The switch state, represented by a binary string according to the individual model’s truth table
in the model datasheet.
4.4.1. I2C Setup Instructions
•Determine the TTL addresses that you wish to set for each switch module (refer to the model datasheets for details).
•Specify the address within the control cable by connecting the relevant lines to DC ground for logic ‘0’ or leaving them
disconnected / floating for logic ‘1’.
•Connect the control cable to the I2C master device.
•Power to the switch can be provided either via the I2C port (see model datasheet for details) or via the USB port through a
USB device or a power adaptor such as USB-AC/DC-5+.

Rev. H | ECO-018898 | 21-Aug-2023Page 13
4.5. SPI Control (U2C-1SP2T-63VH only)
The serial interface requires a full byte to be sent to each unit, although only the two LSB (least significant bits) affect the state of
the switch. The control byte is loaded in a serial-in, parallel-out shift register buffered by a transparent latch.
It is controlled by three-wire SPI protocol using Data, Clock, and Latch Enable (LE) and an additional Blank for added noise immunity
and increased flexibility in controlling the units. While Blank is at logic 1 the SPI interface is enabled, when Blank drops to logic 0
the unit will not respond to SPI control.
All signal voltages are compatible with TTL and LVTTL. The Data and Clock inputs allow data to be serially entered into the shift
register, a process that is independent of the state of the LE input. The dual input and output SPI ports allow up to 30 units to be
connected in a “Daisy-chain” configuration, all controlled by a single controller.
The LE input controls the latch. When LE is ‘1’, the latch is transparent, and the contents of the serial shift register control the
switch. When LE is brought to ‘0’, data in the shift register is latched.
Blank is used to lock the current state of the switch regardless of LE state or shift register, while allowing the LE to pass to other
switches in the chain. If Blank is at logic 1 the switch will respond to LE normally, when Blank is at logic ‘0’ the switch will not
respond to LE. If Blank is not required, it can be kept constantly at logic ‘1’.
The shift register should be loaded while LE is held at ‘0’ to prevent the switch state from changing as data is entered, and Blank
at ‘1’ to allow the unit to respond to the SPI interface. After LE is raised to ‘1’ to enable the switch changing, Blank should be held
at ‘0’ to prevent noise being received as SPI control signals. If multiple units are connected in series, data for all units should be
entered before raising the LE to prevent switches assuming unanticipated states, and Blank kept at ‘1’ until setting of all switches
has been completed. Thus, for example, if three units are connected in daisy-chain all 6 bits of control should be entered before
raising the LE.
The LE input should then be toggled to logic ‘1’ and brought to logic ‘0’ again, latching the new data, then Blank brought to logic
‘0’ as well. The timing for this operation is defined in the model datasheet.
4.5.1. SPI Setup Instructions
•Connect in series all the units you wish to control in the SPI daisy-chain (maximum 30 units).
•Connect the first unit to a suitable controller and 24V power supply.
Caution:
•Be careful not to connect the 24V power to the I2C port as this could damage the unit.

Rev. H | ECO-018898 | 21-Aug-2023Page 14
4.6. Daisy-Chain Control
Some models include Mini-Circuits’ novel dynamic addressing daisy-chaining interface which allows multiple switches to be
connected together into a master/slave chain, with independent control of each switch through the single USB or Ethernet
connection of the master unit (see section 2.4 for models supporting this function).
The serial master/slave bus allows connecting modules of different types to the same daisy-chain as long as they all support
Mini-Circuits’ dynamic addressing setup. To add a new module, simply connect it to the daisy-chain and refresh the address
listing – no need to reset any of the existing modules or assign addresses manually.
Modules will have their addresses assigned automatically when the USB connection from the PC to Master is established, or when
a refresh address command is issued. The module connected to the computer USB port will be assigned address 0 (master), and
subsequent modules connected through it will get incrementing addresses, starting from 1 to N. All control will be through the
master module (address 0) which is the only one communicating with the PC.
Note:
•It is possible to connect up to 99 units in a single setup as long as power considerations are taken into account. Refer to model
datasheets for number of units tested in series of a given model.

4.6.1. Daisy-Chain Setup Instructions
Digital & DC connections for daisy chain control can be done in any order so long as addresses are refreshed once all units and
power supplies are connected.
•Arrange the required switch modules on the work surface in the order that they are to be addressed.
•Use the serial control cables (CBL-1.5FT-MMD+, CBL-5FT-MMD+, or equivalent) to connect the units together in the daisy-
chain, from Serial CTRL Out of the first unit, to Serial CTRL In of the second, and so forth.
•Note the DC current draw of each switch in the daisy-chain from the published datasheets.
•Starting from the first switch in the daisy-chain, sum the DC current draw of each switch to confirm whether the total
exceeds the maximum pass-through current (500 mA), or the maximum available from the USB supply (if lower).
•If required, connect an additional 5V DC power supply to the USB port of one of the daisy-chained modules, to keep the DC
consumption of the previous group beneath the specified limit.
•Repeat the check from this module forward and add additional power supplies as necessary.
•Finally, connect the USB cable from the first switch to the control PC and the complete chain will power up and
automatically assign address (from 00 to NN).
•To add additional units to the daisy chain, repeat step 6 from the last unit connected to a power supply, then connect the
additional units with serial control cables. When done, click on the network reconnect button in the GUI (shown below)

5 -Using Mini-Circuits’ GUI
All solid-state switch models are supplied along with API programming objects (DLL files) to allow easy control by most common
lab test software (see programming manual for details) and with a Windows GUI program to control the model manually.
5.1. Getting Started
To start the program, use the Start menu or navigate to the location the “Mini-Circuits Solid-State Switch Controller” software
was installed in and run the program.
Once running, the user will be required to pick one of the available control modes: USB, HTTP, Telnet, or SSH control.
In addition to the control modes, the user can try the demo mode:
•Select a model from the drop-down menu to learn and experiment with its GUI without connecting said model.
•The “Daisy-chain configuration” presents the GUI for a set of multiple switch models connected using the daisy-chain feature.
5.1.1. USB Control
Clicking the USB button in the startup screen will start the unit in USB control. In case the program does not detect a unit connected
to the PC via USB or if there are no connected units then an alert will pop-up. If the alert persists even when a unit is connected,
then check the unit’s USB LED indicator or the USB cable’s integrity.
If multiple units are connected to the PC via USB, select the desired unit’s serial number from the list in the drop-down menu.

5.1.2. Ethernet Control
To use Ethernet control with a supporting unit, either enter its IP address on the startup screen (ports for HTTP/Telnet/SSH would
also be required if using non-default ports) or click on the search icon next to it to find all Mini-Circuits switch models connected
to the network.
Note:
•When connecting to the unit with Ethernet control for the first time you may need to connect using default IP address or
change the factory default Ethernet configuration to match your network configuration. See section 5.4 or the programming
manual for details.
After clicking on the search icon,the IP search will pop up with a list of switch models’ IP addresses and their assigned ports on
the left side of the screen, and full details of each unit on the right. Click the IP address of the desired unit and press Select. The
search window will close and the IP address, along with the related assigned ports, will be entered in the IP address field of the
startup screen automatically.
Figure 5.1.2a: Ethernet IP search window
Note:
•To refresh the list of found units click on the Search…button.
•The search function uses ports UDP 4950 and UDP 4951 for communication. Ensure your firewall allows access to them.

Once the IP address has been entered, input the password if one has been set (see section 5.4). Proceed to select the desired
communication protocol (HTTP, Telnet, or SSH) and click on the Ethernet button to begin.

Telnet or HTTP text commands can also be used to control the module. This can be achieved in one of the ways below:
•Type the command in the address field of your internet browser.
•Implement a Get/Post HTTP function in your selected application (for HTTP).
•Establish a Telnet connection.
A full list of the possible commands and queries is available in Mini-Circuits Programming handbook, and in a text file on the
downloaded software, in the Ethernet directory.
