Split-Phase Evaluation Board is an electrical measurement unit for performing measurements from a single electrical outlet. It incorporates the TSC 78M6612 power and energy measurement IC. The 78M6612 Split-Phase Evaluation Board is connected to a PC through a USB cable such as one provided in the demo kit package. Optionally, the 78M6612 UART TX & RX signals can be accessed via a header for communicating with an external controller or wireless communications module. The Evaluation Board demonstrates the capability of the 78M6612 energy meter controller chip for measurement accuracy and overall system use. The board is pre-programmed with Split-Phase Demo Firmware in the flash memory of the 78M6612 IC, which allows evaluation of the IC’s capabilities. The 78M6612 Split-Phase energy measurement data and status is read back using an ASCII text string CLI command set. Easy manual operation is performed using HyperTerminal. Optionally, ® a Windows -based Graphical User Interface (GUI) is provided for simplified access to the following measurement data and controls: • • • • Power, current, voltage and power factor indicator dials Line frequency Alarm indicators Programmable Alarm thresholds 1.1 Package Contents The 78M6612 Split-Phase Evaluation Board Demo Kit includes: • • • • 78M6612 Split-Phase Evaluation Board USB Cable Assembly USB A-B 28/24 1.8M (Tyco/Amp 1487588-3) +12VDC@1A power supply CD with OMU Software and Documentation 1.2 System Requirements The 78M6612 Split-Phase Evaluation Board requires use of a PC with the following features: • • ® PC (1 GHz, 1 GB) with Microsoft Windows XP or Windows 2000, equipped with USB port. Minimum 1024 x 768 video display resolution. Windows and Windows XP are registered trademarks of Microsoft Corp. Rev. 1.1 5 78M6612 Split-Phase Evaluation Board User Manual UM_6612_044 1.3 Safety and ESD Notes EXERCISE CAUTION WHEN LIVE AC VOLTAGES ARE PRESENT! Standard ESD precautions must be taken when handling electronic equipment. The 78M6612 contains ESD protected interfaces. Do not connect test equipment, ICE emulators or external development boards directly to the 78M6612 Split-Phase hardware. Damage to the 78M6612 and external equipment will occur due to the 78M6612’s “high side” reference topology. The 78M6612’s V3P3 (i.e. “high side”) is connected directly to Neutral (Earth Ground) creating a ground reference disparity with any properly grounded external equipment. 1.4 Firmware Demo Code Introduction The Firmware Demo Code provides the following features: • • Basic energy measurement data such as Watts, Volts, current, VAR, VA, phase angle, power factor, accumulated energy, frequency, date/time, and various alarm statuses. Control of alarm thresholds, calibration coefficients, temperature compensation, etc. The following setup is used to facilitate performance evaluation between the user at the PC host and the firmware code in the board: • The Command Line Interface (CLI) via HyperTerminal or comparable terminal emulator on a different operating system. Information about the CLI is presented in Section 3.0. The 78M6612 Split-Phase Evaluation Board is shipped with Demo Code Revision 1.14c or later loaded in the 78M6612 chip and included on the CD. The code revision can be verified by entering the command >i via the command line interface. Firmware for the Evaluation Board can be updated using either the Teridian TFP2 or an in-circuit emulator such as the Signum Systems ADM51 (www.signum.com). The board components and firmware settings are designed to operate with the following nominal AC electrical ranges: Voltage Current Line Frequency 110-240 VAC 10 mA – 20A 46-64 Hz 1.5 Testing the 78M6612 Split-Phase Evaluation Board Prior to Shipping Before every 78M6612 Split-Phase Evaluation Board is shipped, the following procedures have been performed at the factory: • Full Calibration – Precise energy source equipment is used to calibrate the current and voltage. The temperature is also calibrated at the same time. • Accuracy Test – This “bench” level test ensures the energy accuracy is within ±0.5%. 6 Rev. 1.1 UM_6612_044 78M6612 Split-Phase Evaluation Board User Manual 2 Installation The 78M6612 Split-Phase Evaluation Board is intended for use with a 3-wire single-phase distribution system. This 3-wire single-phase distribution system is typically sourced from a distribution transformer with a single-phase input (primary) winding. The distribution transformer’s secondary winding has a center tap which is defined as Neutral. Line 1 and Line 2 exist on either side of Neutral exhibiting a 180° phase shift between them. The 78M6612 is referenced to Neutral and measures both voltages present on Line1 and Line 2 with respect to Neutral. Additionally, load currents flowing in both Line 1 and Line 2 are measured. The following figure shows the 78M6612 Split-Phase Evaluation Board’s measurement inputs with various load configurations. CT1 I1 Line 1 ILOAD 1 Neutral V2 LOAD3 V1 ILOAD 2 Line 2 I2 CT2 INeutral Figure 1: Split-Phase Energy Measurement Configuration Rev. 1.1 7 78M6612 Split-Phase Evaluation Board User Manual UM_6612_044 2.1 Basic Connection Setup Figure 1 and 2 show the basic connections of the 78M6612 Split-Phase Evaluation Board for use with external equipment. The 78M6612 Split-Phase Evaluation Board is powered either by an on-board ACDC switcher or from an external +12VDC power supply. A USB cable provides the communications link between the host PC and the 78M6612 Split-Phase Evaluation Board. The high voltage AC source and load wires connect to spades mounted on the bottom side of the board. J2 ACDC Switcher External +12VDC USB Connector . Figure 2: Top Side 78M6612 Split-Phase Evaluation Board Connections Install jumper J2 when using the on-board ACDC switcher. The switcher draws power from one of the AC inlet phase wires. Remove jumper J2 when attaching an external +12VDC power supply to disconnect the switcher from the AC inlet. The board draws less then 100ma from the external +12VDC supply. Use an external +12VDC power supply which is fully isolated. 8 Rev. 1.1 UM_6612_044 78M6612 Split-Phase Evaluation Board User Manual J13 J4 J5 J18 J16 J7 Figure 3: Bottom Side 78M6612 Split-Phase Evaluation Board Connections The high voltage AC wires attach to the spades located on the bottom side of the board. The following table describes the wiring connections. Table 1: High Voltage AC Connections Rev. 1.1 Connector External Circuit J4 Neutral – from Source J5 Neutral – to load J7 Line 1 – from Source J13 Line 2 - from Source J16 Line 1 – to Load J18 Line 2 – to Load 9 78M6612 Split-Phase Evaluation Board User Manual UM_6612_044 Line 2 Neutral Host PC Line 1 Split Phase AC Source 78M6612 SP Eval Board USB USB Controller Isolation ACDC Switcher 12VDC 3V3 Reg UART Current Shunt 6612 Voltage Divider Voltage Divider Relay Relay 10x DIOs I2C Split Phase AC Load Under Test Figure 4: 78M6612 Split-Phase Evaluation Board Application Diagram The 78M6612 Split-Phase Evaluation Board is preconfigured to measure the Load currents present on Line 1 and Line 2 using two current transformers (CT). Alternatively, the board has provisions the replace the Line 1 CT with a current sensing shunt in series with the Neutral wire. Two resistors (R18 and R43) provide the sensor selection. The following table provides the resistor population options for selecting the CT versus the shunt. Table 2: Line 1 versus Neutral Current Sensing Configuration Sensor Configuration R18 R43 CT – Line 1 No Component Install 750Ω Shunt - Neutral Install 750Ω No Component Presently the firmware only supports the CT–Line1 configuration. 2.2 Relay Configuration The CLI commands support separate Line 1 and Line 2 relays. However, the 78M6612 Split-Phase Evaluation Board uses DIO7 to control both Line 1 and Line 2 relays so that control of power to both remains in sync. 10 Rev. 1.1 UM_6612_044 78M6612 Split-Phase Evaluation Board User Manual 2.3 Optional UART Interface The 78M6612 Split-Phase Evaluation Board provides an option to bypass the on-board serial USB controller. This option is useful for communicating with an external controller or attachment of a wireless module. The optional UART interface is accessible via connector J12. Remove the 0Ω resistor R38 to prevent TX contention with the on-board isolator’s output, U3. UART Connector J12 Remove R38 Figure 5: UART Connector Due to the 78M6612’s V3P3 being directly connected to Neutral, the Teridian supplied UART isolator must be inserted between the evaluation board and the external controller. The V3P3 to Neutral connection results in the 78M6612’s GND pin being 3.3V below the external controller’s GND pin. Additionally, the UART isolator board provides for galvanic isolation between the evaluation board and the external controller hardware. Installed UART Isolator Daughter Card Short cable harness to external controller Figure 6: UART Isolator Daughter Card Rev. 1.1 11 78M6612 Split-Phase Evaluation Board User Manual UM_6612_044 Table 3: J12 UART Connector Pin Assignments J12 Pin Number Identifier Function 1 V3P3 +3.3V to daughter card 2 TXD 78M6612 TXD output 3 RXD 78M6612 RXD input 4 GND GND to daughter card The UART Isolator daughter card maintains the same pin functions on its connector interface to the external controller. The UART isolator board is not required when using a wireless module. However, use of an antenna with an exposed metal mounting base presents a safety hazard. The other consideration regarding use of a wireless module is the module’s transmitting power consumption. The on-board switcher can provide only 100mA (at 3.3V). Use an external power supply if the transmitter’s power is greater than 100mA. 12 Rev. 1.1 UM_6612_044 78M6612 Split-Phase Evaluation Board User Manual 2.4 USB Driver Installation This evaluation kit includes an isolated USB interface for serial communications with a PC. The FTDI USB controller IC FT232R performs the USB functions. The FTDI Windows driver presents a virtual COM port for enabling serial communications. Control of the 78M6612 Split-Phase Evaluation Board can be managed using either a terminal emulation program or using the supplied Windows GUI. The FTDI Windows driver is a certified driver for Windows 2000 and XP. 1. Upon attaching the 78M6612 Split-Phase Evaluation Board to the PC, the Found New Hardware Wizard automatically launches and installs the appropriate driver files. If your PC does not find the FTDI driver files on its local hard disk drive, locate and reference the FTDI USB Driver and Utilities subdirectory on the CD. The FT232R controller is powered from the USB cable and is active even when no power is applied to the 78M6612 Split-Phase Evaluation Board. Notes: If an older FTDI driver has been previously installed, it is recommended to remove the older version before installing this newer FTDI driver. Execute the ftdiClean.exe utility from the FTDI USB Driver and Utilities subdirectory. For FTDI driver support on other operating systems, please check FTDI’s website at (Error!

The COMn Properties menu appears. Rev. 1.1 15 78M6612 Split-Phase Evaluation Board User Manual UM_6612_044 Note that port parameters can only be adjusted when the connection is not active. It may be necessary to click the Disconnect Button to disconnect the port. Disconnect FTDI COM Port Trouble-Shooting If the FTDI device driver did not install properly, there would be no assigned COM port number for the FTDI controller. Repeat the USB Driver Installation, see Section 2.3. Microsoft Windows may associate a Ball Point device to the FTDI USB controller. When this occurs a FTDI device COM port assignment is available via HyperTerminal but there is no communications data. Verify if a Ball Point device has been added to the “Human Interface Devices” via the Device manager. Refer to Section 2.4 for access to the Device Manager. If a Ball Point device exists, delete it and unplug and replug the evaluation board’s USB cable. 16 Rev. 1.1 UM_6612_044 78M6612 Split-Phase Evaluation Board User Manual 3 Initialization and Calibration The 78M6613 Split-Phase Firmware includes a relay control routine that initializes the relays in the ‘off’ position. Until relays are turned ‘on’ using the TC0 command, only voltage, line frequency, and chip temperature can be measured and reported. To globally turn on or off relays with the Split-Phase Firmware, the following commands should be used. >TC0 (turn on all relays) >TC3 (turn off all relays) The Split-Phase firmware also includes built in calibration routines. Using the precision source method, a known external voltage source, ambient temperature, and current source (load) is provided to the evaluation board during calibration by Teridian. The routine automatically adjusts coefficients until measured values match known (target) values and saves them to flash memory. It is recommended the user read back and record these calibration coefficients. This will allow the user to re-store the calibration settings should the firmware for the evaluation board be updated in the future. There are four calibration coefficients: one for each voltage input and one for each current input. These four coefficients are read back using the ]8???? command. Rev. 1.1 17 78M6612 Split-Phase Evaluation Board User Manual UM_6612_044 4 Windows Graphical User Interface (GUI) The 78M6612 Split-Phase GUI displays RMS voltage and current, power, volt-amperes, and power factor for two independent phases as well as totals for these parameters.
