Introduction
The mb-Technologies HVM high voltage switch series is a computer-controlled switching matrix designed for semiconductor characterization applications. It connects a number of instruments – connected to the matrix inputs – to test structures connected to the matrix outputs.
The connection is done using a high voltage relay matrix with guarded contacts. Optionally, triple-switch FORCE, SENSE and GUARD relays are used at each switch point to support low-leakage Kelvin measurements. Connections are shown on the front panel dot matrix display.
The base system supports a switch matrix with up to 12 inputs and 12 outputs. Expansion units can be added to increase the number of outputs.
CAUTION: It is highly recommended to switch the relays without any voltage or current applied. This is referred as cold switching. Please note the switching capabilities under voltage or current is limited. Also the lifetime my be affected (see Specifications).
The switch matrix supports a discharge feature which connects the relay matrix to ground using 1M resistors. Discharge can be activated either by software, with a push button on the front panel or using a control line of the digital I/O interface.
Various communication interfaces are supported. The equipment can also be controlled from the front panel for testing and debugging purposes.
Installation
When you receive and open the box, check the packaging material and the equipment for any signs of damage like dents, scratches, cuts or water marks.
Check the components list: Switch matrix Mounting flanges (2) w/ screws (6) User’s manual Power cable (may not be included for certain areas)
For an expansion unit please check the following components: Switch matrix expansion unit Mounting flanges (2) w/ screws (6) Communication cable Input connection cables (optional, number and type depends on the matrix connectors) Power cable (may not be included for certain areas)
WARNING: This equipment is heavy and may only be lifted or moved by 2 persons. It’s recommended to hold it on the left and right side.
After unpacking, connect the power cable and power the equipment using the rear side switch and the front panel push button. If installing an expansion unit, connect use the communication cable with either SYNC connector, also connect all matrix inputs between the units.
Wait until the power-on tests have finished then check the operation by executing a self-test (see Self-Test).
GPIB, USB, LAN or RS232 communication connectors are available. Please note communications cables are not included. You may need to set the communication parameters before it can be used (see Communication Setup).
If the equipment is to be installed in a rack or cabinet, mount the flanges using a cross-tip screwdriver PZ2.
WARNING: If installed in a rack or cabinet, the equipment should be screwed-on to prevent falling out.

WARNING: When installing this equipment in places where access to the main power cord is restricted, such as rack mounting, a separate main input power disconnect device must be provided, in close proximity to the equipment and within easy reach of the operator.
WARNING: Chassis connections must only be used as shield connections for measuring circuits, NOT as safety earth ground connections.
WARNING: The switch matrix comes with connectors equipped to the users requirements. These connectors may be of different type. While the relay matrix can always handle high voltage, some connectors may be rated much lower voltage, e.g. BNC/Triaxial connectors are rated 500 V only. It is the user’s responsibility only to use voltages which can be handled by the connectors. Depending on the interface options installed, GPIB, USB, LAN or RS232 connectors may be available. The interface to be used is selected using the front panel (see Setup section below).
For safety and noise reasons a separate ground connection is recommended using the ground tab marked with this symbol.
Self-Test
Power-On Self-Test:
After powered on, the equipment executes a series of internal tests. This takes about 20 seconds. The device cannot be accessed during this time. The display shows the model, the serial number and the hardware and firmware versions.
Relay Matrix Test:
The power-on self-test does not include testing the relay matrix. This test can be invoked either manually using the TEST button or by software (see Command Reference).
Disconnect all measurement cables before starting the relay test! The test may fail if cables are connected.
Any problems found by these tests are shown on the display.
Communication Setup
Press the MENU button, then 1 (SETUP) to select the communication interface and options. Select the interface and proceed with OK then set the options for this interface.
Any interface can be used, but only one interface can be used at a certain time. Once the interface is used, it is shown in the front panel.
Do not use the interface connectors of the expansion box, if there are any.
USB Setup:
Connecting the switch matrix to a PC by USB installs a virtual serial communication port. Usually the driver is already installed in your operating system or found automatically. If you get an error message you can download the VCP driver from https://ftdichip.com/drivers/vcp-drivers/. Installation guides for various operating systems can found at http://www.ftdichip.com/Support/Documents/InstallGuides.htm.
Please check the Device Manager in your Control Panel to identify the new USB serial port in the COM & LPT section. The communication settings like baud rate and parity don’t care as these settings are just virtual however it is recommended to change the BM latency timer from “16 ms” to “2 ms” (right click the port and select Properties, Port Settings, Advanced).
Alternatively the USB port can be accessed directly using the D2XX library which is installed with the same driver as described above.
You can then communicate using this serial port and the commands described in Command Reference

This installation only needs to be done once. The port automatically becomes available each time the switch is connected and turned on.
LAN Setup:
Connect the switch to your local network and turn it on. Press SETUP, select 1 (SETUP), 3 (LAN) and press OK. Either select AUTO to use automatic DHCP configuration or MANUAL to define your own network settings. In manual mode the IP address, the address of the gateway, the DNS server and the network mask can be defined. The switch can be accessed through TCP/IP port 10001 using the IP address of the switch. Alternatively a virtual serial port can be assigned to the switch. The switch can then be accessed like any serial communication device. Install the software Com Port Redirector from https://www.lantronix.com/products/comport-redirector/ and start the CPR Manager. Press Add/Remove and check an unused port number, then press OK. Select the new port then press Search for Devices. The switch should show up in the Device List window. Right click it and select Add To Settings. Click Save in the command bar to install the device driver. Accept the firewall warning. You may need administrator rights to do this. This will install a new serial port. You can then communicate using this port and the commands described in Command Reference. The communication port’s settings like baud rate and parity don’t care as these settings are just virtual. This installation only needs to be done once. The port automatically becomes available each time the switch is connected to the network and turned on. It may take up a few seconds up to a minute until the switch is recognized by the network. If connected to a network the IP address of the switch is shown on the display. Also the IP address of the controlling computer is shown.
GPIB Setup:
Press MENU, select 1 (SETUP), 1 (GPIB) and press OK. Enter the GPIB address to be used. Press OK to save the settings.
RS232 Setup:
Press MENU, select 1 (SETUP), 4 (RS232) and press OK. Select the baud rate and press OK to save the settings. The communication uses 8 bits, no parity, 1 stop bit. It only supports the TXD and RXD. Handshake lines are not used.
Display and Keyboard
In most cases the switch matrix will be controlled by software using the communication interfaces. The display and keyboard is useful for debugging purposes.
The front panel has several push-buttons, a color graphics display and a led matrix display. The dot matrix display shows the relay status all the time. A green dot indicates a connection between the row and column shown.

A full row or column can be selected with ‘0’. Press CLOSE or OPEN to change the status, then press OK. The relay is switched immediately. This is also shown on the matrix display.

Note a maximum of 25 relays can be closed at any time.

CAUTION: It is highly recommended to switch the relays without any voltage or current applied. This is referred as cold switching. Please note the switching capabilities under voltage or current is limited. Also the lifetime may be affected (see Specifications).

The SAVE button stores the current matrix configuration. You can choose one of 12 memory slots by pressing a number key and OK. The LOAD button restores a previously saved setup. The memory is retained when power is turned off.

The RESET button opens all relays. When pressing RESET twice, the LOAD/SAVE memory is cleared.

If the switch is controlled by software it changes to REMOTE mode and the keyboard is locked. This is shown by the REMOTE indicator on the display. If the software does not release the equipment after use the switch can be released manually by pressing the LOCAL key twice.

Backside Panel

The backside panel has connectors for the matrix inputs and outputs. The switch matrix comes with connectors equipped to the users requirements. These connectors may be of different type. While the relay matrix can always handle high voltage, some connectors may be rated much lower voltage, e.g. BNC/Triaxial connectors are rated 500 V only. It is the user’s responsibility only to use voltages which can be handled by the connectors.
Each input and output may have one connector, or two: FORCE and SENSE. If SENSE is not used it can be left open. FORCE and SENSE is connected internally with a 10M resistor.

WARNING: Do not try to use non-matching connectors or wires.
WARNING: The maximum voltage rating for each connector is labeled on the backside panel. Do not apply any higher voltage. This also applies to connections through the matrix.
The right side of the backside panel has USB, LAN, RS232 and GPIB communication interfaces, a digital I/O connector, a ground connector stub and the main power jack connector with integrated switch and fuses installed. Depending on the configuration some of the communication interfaces may not be available.
Maintenance
WARNING: This equipment does not contain any user serviceable parts inside. Only properly trained service personnel may open the equipment and perform service procedures.
WARNING: Disconnect all external power from the equipment and the line cord before performing any maintenance. Failure to disconnect all power may expose you to hazardous voltages, that if contacted could cause personal injury or death.
CAUTION: For continued protection against fire hazards, replace fuse with same type and rating. To replace the fuse, open the fuse drawer between main power jack and power-on switch with a flat head screwdriver.
Fuse rating: 4A slow blow, 250V (5 x 20mm).
To clean the instrument, use a damp cloth or mild, water based cleaner. Clean the exterior of the instrument only. Do not apply cleaner directly to the instrument or allow liquids to enter or spill on the instrument.
Digital I/O Port
The Digital I/O Port is an optional SUBD 25 pin connector located on the backside of the switch:

It provides 16 general digital input/output signals, 4 status lines and 5V power.

The 16 general signals can be used for any purpose and are controlled by communication interface commands. Each line can be defined to be either input or output. All lines confirms to general CMOS signals levels (5 V). The meaning of the 4 status signals is defined in the following table:
