1.0 Introduction For flexible configuration of an EMC test facility and fully-automated testing, the ETS-Lindgren EMCenter™ Modular RF Platform provides space for up to seven plug-in cards in a 3U, 19-inch rack mount enclosure. The EMCenter can also be used as a desktop unit.
The EMCenter contains a Vortex-embedded main processor to control all cards and to interface with the user and/or an external computer. The operating system is Linux-based, providing a stable operating environment, fast startup time, and high performance. All embedded software is stored in flash, making it easy to upgrade to new versions and future functionality.
EMPOWER PLUG-IN CARD AND EMPOWER SENSORS The EMPower Meter Plug-in Card occupies one slot in the EMCenter and includes four USB ports, accommodating any combination of up to four EMPower USB RF Power Sensors. Two versions of the EMPower sensors are available: Model 7002-002 and Model 7002-004: Support RMS measurements for CW signals. Model 7002-003 and Model 7002-005: Measure RF bursts as short as a few microseconds.
EMCONTROL POSITIONER CONTROL PLUG-IN CARD EMControl is a versatile positioner controller which enables you to synchronize the simultaneous movements of up to two ETS-Lindgren positioning devices (for example, towers or turntables) and the on/off operation of an additional auxiliary device, such as a LISN or EUT. EMSENSE EMF PROBE PLUG-IN CARD The EMSense card provides an interface for ETS-Lindgren battery-powered EMC field probes. Each EMSense card can support one probe. 10 Introduction www.
EMGEN RF SIGNAL GENERATOR PLUG-IN CARD The EMGen card is a modular signal generator with AM and pulse modulation, covering a frequency range of 9 kHz to 6 GHz. EMGen is designed for EMC testing, and quickly and accurately performs EMC tests without the need for an external modulation source. Standard Configuration Standard configuration may vary by EMCenter model; contact ETS-Lindgren for additional information.

2.0 Maintenance Before performing any maintenance, follow the safety information in the ETS-Lindgren Product Information Bulletin included with your shipment. WARRANTY Maintenance of the EMCenter is limited to external components such as cables or connectors. Clean the exterior of the cabinet using a damp cloth and mild cleaner. Always unplug the unit before cleaning. To prevent electrical shock, do not remove cover. Warranty may be void if the housing is opened.
Maintenance of Fiber Optics Fiber optic connectors and cables can be damaged from airborne particles, humidity and moisture, oils from the human body, and debris from the connectors they plug into. Always handle connectors and cables with care, using the following guidelines. Before performing any maintenance, disconnect the fiber optic cables from the unit and turn off power. When disconnecting fiber optic cables, apply the included dust caps to the ends to maintain their integrity.

4.0 Laser Safety For additional safety information see the ETS-Lindgren Product Information Bulletin included with your shipment. Safety Precautions LASER RADIATION AVOID EXPOSURE TO BEAM CLASS 3B LASER PRODUCT WAVELENGTH 808 nm OPTICAL POWER 0.5 W Never look into any of the fiber optic connectors. The laser emits an infrared beam that is invisible to the naked eye. Direct or even reflected light will cause permanent eye damage.
Exposure to any laser radiation during normal operation is not likely because the EMCenter uses only fiber-coupled lasers. However, for the safety of all employees, please comply with the following rules: When the EMCenter is not in use, power off the unit. The remote interlock connection should be connected to an emergency master disconnect and in series with the room door or fixture interlocks. Connect all fiber cables and install protective covers before switching on the system.
5.0 EMCenter Controls and Connectors Never disconnect the fiber optic cables when one of the lasers is active. See Manual Control of the EMCenter on page 25 for information on using the touchscreen controls. Front Panel STATUS INDICATORS There are four status indicators on the front panel of the EMCenter™ Modular RF Platform: Interlock—Illuminates if the external interlock is open, or if one of the plug-in card interlocks encounters an interlock error.
Back Panel Slots 1 through 7—Allow you to install a combination of ETS-Lindgren plug-in cards: EMSwitch™, EMPower™, EMControl™, and EMSense™. For more information on the cards, see EMCenter Plug-In Cards (Optional) on page 8. Slot 8—Dedicated to the processor card for the embedded Linux computer. The processor card also provides these connectors: RS-232 Serial interface bus to interface with a computer. Use a straight (pin-for-pin) cable with sub-D9 connectors.
Slot 9—Dedicated to the power supply card. The power supply card also provides a connection for an external interlock. Interlock Safety interlock connection that provides two floating contacts which require shorting for the EMCenter to operate. Use the supplied connector (6.3 mm 1/4-in stereo jack) to wire to the emergency switch of your site. Connect the tip and middle pin. Mains Inlet Used to connect to the mains power to the EMCenter. This IEC inlet holds a primary fuse.

Turn the power switch located on the back panel of the EMCenter to the off position. 4. Remove the power cord from the power connector on the back panel of the EMCenter. 5.
Information Screen Press Info to display the Information screen. Sample Information Screen The Information screen displays after the EMCenter is powered on. It provides the following information: 28 Software version Configured IEEE address (if installed) Plug-in card installed in each slot Manual Control of the EMCenter www.ets-lindgren.
Home Screen Press Home to display the Home screen. Sample Home Screen CARD SLOT NUMBERS Looking at the back of the EMCenter, the card slots are numbered 1 to 7 from left to right. The numbers 1 to 7 on the left side indicate the card slot numbers of the EMCenter. In this example, the following cards are installed: Slot 1: EMPower™ Slot 2: EMSwitch™ No cards are installed in slots 3–7. www.ets-lindgren.
STATUS BOX A status box for each slot displays to the right of the slot number. The box displays an overview of the main parameters for each installed card. This can be the actual field strength for a field probe or the positions of the different switches in case of an EMSwitch™ plug-in card. If no card is installed in a slot, the Status box will display Available. To display or change the data and configuration parameters of a card, press the Status box for that card.
Configuration Screen Press Config to display the Configuration screen. The IEEE address of the EMCenter can be changed here. Sample Configuration Screen IEEE Board—Press Change to enable or disable the board (if installed). IEEE Address—Press Up or Down to change the address (if installed).

8.0 Remote Control of the EMCenter To control a device installed in the EMCenter from a remote computer, the IEEE address of the EMCenter must be set correctly. All commands for plug-in cards must have a two-character prefix: First character: Identifies the type of card. Second character: Provides the device number of the card. Terminate each command with a carriage return (CR).
Second Character: Device ID Number Each card in the EMCenter is assigned a unique device ID number that is the same as the slot number; all commands for plug-in cards must be preceded by the numbered slot where the card is installed. Additionally, if the card provides a multiple port, like EMPower, the port number must also precede the command. A carriage return (CR) must terminate each command. Looking at the back of the EMCenter, the card slots are numbered 1 to 7 from left to right.
If a card slot supports more than one device, the device ID is the slot number, followed by the port number of that card slot. For example, using the previous table: To access the second EMPower in slot 3: Use device ID number 3B. To access the EMLink in slot 2: Use device ID number 2.
Command Set and Error Codes Following are the general commands and error codes for the EMCenter. For device-specific commands, see the separate manual for each card. COMMAND SET Command Message Description *IDN? Request the identification of the EMCenter Response: ETS-Lindgren EMCenter version x.x.
