SLM MANUAL Specification Controls (Custom Models Only) i 118073-001 Rev C Chapter 1 Output Voltage: 22 models: 1kv to 70kv INTRODUCTION ≤ 0.01% of rated output voltage over specified input voltage range ≤ 0.01% of rated output voltage for a full load change 1.1 Description of the SLM Series T he SLM Series of high voltage generator modules are designed for OEM applications up to 70kV and up to 1200watts. Its universal input, small package size and choice of three standard digital interfaces simplifies integrating the SLM into your system. DSP based control circuitry provides excellent regulation, along with outstanding stability performance. User programmable firmware option makes the operation of the SLM flexible. Ripple: ≤ 0.2% rms of maximum rated voltage, measured with a 10 foot long HV cable Polarity: Positive or Negative polarity with respect to ground. (Specify at time of ordering). Stability: ≤ 50ppm/hr after a 2 hour warm up Temperature Coefficient: ≤ 100ppm / C. Temperature: Operating: 0C to 40C Storage: -40C to +85 Humidity: 20% to 85% RH, non-condensing. The DC output voltage and current are controllable over the full range of operation. Monitoring and control signals are provided for simple, yet flexible control of the power supply. The SLM series operates from 90 265Vac, at 50/60 Hz single phase for the 300Watt models and 180–264Vac, at 50/60 Hz single phase for the 600Watt and 1200Watt models. The input is power factor corrected and the SLM series operates at full power continuous. The ambient temperature must be kept below the maximum rating as specified in 1.2. The standard warranty applies to the modules. Consult factory about the warranty for custom SLM modules. Control Interface Local Interface: Voltage and current are externally programmable over the entire range from zero to maximum rating via 0-10VDC input. 1.2 SLM Specifications +10Vdc Reference: A +10Vdc reference is provided for local programming via two potentiometers to be used to adjust voltage and current. Remote Interface: USB, Ethernet and RS232 are standard, implemented with 12 bits of resolution. All digital monitors have an accuracy specification of 2%. Control Software: A VB GUI will be provided for RS-232/USB, the Ethernet interface will have an embedded applet for control. Monitor Signals: Voltage and current monitor signals are scaled 010Vdc equals 0-100% of full scale. Accuracy is 1%. Input Voltage: 90-264Vac 47-63Hz, for 300watt models 180-264Vac 47-63Hz, for 600watt models 180-264Vac 47-63Hz, for 1200watt models Power Factor: FL: ≥ 0.99 SLM MANUAL Current Regulation: ≤ 0.01% of rated output current over specified input voltage range ≤ 0.01% of rated output current for a ±100μA for a full voltage change The dramatically reduced size of the SLM module, compared to traditional high voltage modules, is obtained by a state of the art off-line resonant converter. The resonant converter utilizes a unique control scheme, which allows constant frequency operation while maintaining high efficiency. The high efficiency is obtained by zero current switching (ZCS) resonant control. High operating frequency, typically 50 kHz, allows for low ripple and excellent dynamic response capabilities. Voltage Regulation: 1 118073-001 Rev C Remote Overvoltage Adjust: ROV The overvoltage trip protection feature shuts down the high voltage output when the voltage exceeds the limit configured in the firmware. The DSP inhibits the generation of high voltage and reverts the unit to HV OFF mode, illuminating the OVER VOLTAGE indicator. This can be enabled in the firmware and is adjustable from 0% to 110% of full-scaled output voltage. The select values are stored internally in the SLM memory. When ROV is disabled the default overvoltage trip point is 110% of full-scaled output. The factory default setting for ROV is disabled. HV Control Enable/Interlock: A dry contact, hardware based interlock is provided for remote mode. In local mode this I/O is the enable. IMPORTANT This control signal in not a safety interlock and should not be used for protection from high voltage generation for safety purposes. Cooling: Forced air Dimensions: 4.75˝ H X 6˝ W X 12˝ D (120.65mm x 152.4mm x 304.8mm) Weight: 14 pounds (5.44kg) Input Line Connector: IEC320 cord set with integrated EMI filter Output Cable: A detachable 10’ (3.3m) long shielded HV cable is provided ARC Trip: AT The SLM provides firmware configurable arc detection. The user can set the arc detection parameters to custom fit their requirements. The follow parameters are programmable in the firmware and are stored internally in the SLM memory: Arc Count: This sets how many arc’s are require within the selected time period to cause an arc shutdown. It is programmable from 1 arc to 20 arc. The factory default setting is 8 arc. Time Period: This sets the time period that the selected arc count must occur within to cause an arc shutdown .It is programmable from 1 second to 60 seconds. The factory default setting is 20 seconds. 1.3 Standard Features Quench Time: This sets the length of time that the high voltage is shutdown to quench the arc after an arc occurs. It is programmable from 100ms to 500ms. The factory default setting is 500ms. The SLM series incorporates several standard features designed to optimize user operation. Standard Firmware Configurable Features: Re-Ramp: After an arc occurs, the kV output will slow start at the programmed ramp time. If Re-ramp is disabled then there will be no ramping after an arc. The factory default setting is enabled. Slow Start: Provides a gradual increase in high voltage output until the maximum set point is reached. This ramp time can be configured in the firmware from 0.1 seconds to 60 seconds, and is stored internally in the SLM memory. The factory default setting is 5 seconds. The SLM will not accept Arc Count and Time Period setting that exceed 1 arc per second. Adjustable Overload Trip: AOL The overload trip protection feature shuts down the high voltage output when the current exceeds the limit set by the current control. The DSP inhibits the generation of high voltage and reverts the unit to HV OFF mode, illuminating the OVER CURRENT indicator. This can be enabled in the firmware and is stored internally in the SLM memory. When AOL is disabled the default overcurrent trip point is 110% of full-scaled output. The factory default setting for AOL is disabled. SLM MANUAL No Arc Detect: NAD When No Arc Detect mode (NAD) is enabled, the HVPS has no arc shutdown protection. The HVPS is designed to handle an arc rate of 1 arc per second. Exceeding 1 arc per second could cause damage to the HVPS. HVPS failure caused by excessive arc will not be covered under the warranty. The factory default setting for NAD is disabled. 2 118073-001 Rev C Watchdog Timer If there is no communication between the HVPS and the host computer for more than 10 seconds the HV output will shutdown and the Watchdog Timer fault will be sent via the digital communication when and if communication is resumed. This can be enabled via the digital communication and is defaulted to disable upon power up. Standard Input Features: Power Factor and Universal Input: The input voltage of the SLM can operate within the range from 90Vac to 265Vac for the 300Watt model and at 180–264Vac, for the 600Watt model. The power factor is actively corrected across this entire range and is better than 0.99 at full load. Internal EMI Filter and Fuse Protection: An internal EMI filter and fuse provide protection against line voltage surges and power supply faults. OVER CURRENT FAULT: Indicates the over current protection circuitry has caused the high voltage to turn off. This fault will occur if the output current exceeds 110% of full scale. If AOL is enable this fault will occur when the current exceeds the current program set point. This fault is indicated by illumination of over current LED status on the front panel and via RS-232, USB or Ethernet as Over Current. OVERVOLTAGE: Indicates the over voltage protection circuitry has caused the high voltage to turn off. This fault will occur if the output voltage exceeds 110% of full scale. If ROV is enable this fault will occur when the voltage exceeds the programmed ROV setpoint. This fault is indicated by over voltage LED status on the front panel and via the RS-232, USB or Ethernet as Over Voltage. ARC FAULT: Indicates that the programmed arc count was exceeded within programmed time period. This fault is indicated by steady state illumination of Arc Fault LED status on front panel and via RS-232, USB or Ethernet as Arc Fault. The LED will pulse for each arc, but will be a steady state ON if a shutdown occurs. REGULATION ERROR: Indicates a failure in the voltage, current or power regulation circuitry. This fault usually occurs when there is a lack of output power to maintain regulation. This fault is indicated by illumination of the Regulation Error LED status on front panel and via RS-232, USB or Ethernet as Under Current. OVER TEMPERATURE: Indicates either a failure in the cooling system that would cause the internal heat sink temperature to exceed the operating range or the ambient temperature to exceed 40 degrees C, resulting in shutdown of HV. This fault is indicated by Over Temperature LED status on the front panel and via RS-232, USB or Ethernet as Over Temperature. PS Fault Indication: PS Faults an open collector output with a 1k ohm impedance on J2-1, indicates that a faults has occurred. High = no faults HV On Indication: HV On Signal is an open collector output with a 1k ohm impedance on J2-14, indicates that HV is enabled. High = HV OFF HV On LED: When the high voltage status is “On” state it is indicated by HV ON LED status on the front panel. Remote Operating Features Remote Control: USB, Ethernet and RS232 are standard. A provided G.U.I allow user to control the unit via RS232 and USB interfaces. An imbedded Applet web browser allow user to control the unit via Ethernet. Refer to SLM digital protocol spec for details. Remote Monitor: Allows remote monitoring of the Output voltage, current, HV On clock counter, and user configurable firmware features via the USB, Ethernet or RS232. Remote Programming: Allows remote programming of the output voltage, current and user configurable firmware features via the USB, Ethernet or RS232.

See Figure 3.4 for monitoring wiring and see data sheet for pin outs. 3.2 Standard Features A note on remote interface circuitry and remote signal grounding: whenever possible, electrical isolation should be provided when interfacing with any high voltage power supply. For enable/disable signal connections, an isolated relay or optocoupler should be used. For PS Fault indication an optocoupler should be used. If possible, analog programming and monitoring signals should be isolated via analog isolation amplifiers. Spellman application engineers are available to assist in interface circuitry design. All interface cables should be properly shielded. All power supply signals should be referenced to the power supplies signal ground or power supply chassis ground HV Enable/Interlock: In Local Mode allows ON/OFF control of the high voltage. The hardware based dry contact closure must be closed in to enable the high voltage. In Remote Mode this I/O acts as an Interlock. The hardware based dry contact closure must be closed in order to enable the high voltage via the USB, Ethernet or RS232. This can be done by connecting pins 11 and 12 on J2. See Figure 3.5. REMOTE PROGRAMMING: After establishing communication with the UUT as per the SLM Digital Protocol spec. Switch the UUT to Remote Mode by sending a Program Local/Remote Mode command (this is done automatically upon opening of the Spellman GUI/APPLET).If the unit is in Local Mode and enabled prior to switching it to Remote Mode, the UUT will shutdown and a P.S Fault indictor will occur when it is switch to Remote Mode. A clear command can be sent to clear this fault. Local Programming potentiometers: The voltage and current controls on the front panel can be used as follows: For local current control, jump J2-2 to J2-7. For local voltage control, jump J2-3 to J2-5. See Figure 3.2. LOCAL PROGRAMMING: Allows local adjustment of the output voltage and current level via an external voltage source. 0-10Vdc signal is supplied to pin 3 of the J2 for voltage programming and 0-10 Vdc signal is supplied to Pin 2 J2 for current programming. Programming signals should be referenced to Pin 9 of J2, signal ground. By adjusting the voltage source from 0 volts (zero output) to 10 Vdc (full rated output) the desired output can be selected. See Figure 3.3 for wiring diagram and specifications. Remote Control: USB, Ethernet and RS232 are standard Refer to SLM Digital Protocol spec for Details. Remote Monitor: Allows remote monitoring of the Output voltage and current via the USB, Ethernet or RS232. Remote Programming: Allows remote programming of the Output voltage and current via the USB, Ethernet or RS232.

SLM MANUAL 12 118073-001 Rev C Chapter 4 PRINCIPLES OF OPERATION T he SLM Series of high voltage power supplies utilizes sophisticated power conversion technology. Advanced analog and power conversion techniques are used in the SLM series. The intention of the Principles of Operation is to introduce the basic function blocks that comprise the SLM power supply. For details on a specific circuit, consult Spellman’s Engineering Department. be present before and after the power supply is used. Consult IEEE recommended practices for safety in high voltage testing #510-1983. 4.2 High Frequency Inverter The SLM is a resonant converter operating in a zero current switching, series resonant, parallel loaded topology. MOSFET transistors switch the 400 Vdc voltage to the resonant tank circuit. Typical operating frequency is in the range of 35-65 KHz depending on model. Control of the resonant circuit output is done by the low voltage control circuits, and are isolated by an isolated pulse transformer. The output of the resonant circuit is applied to the primary of the high voltage transformer. The SLM power supply is basically an AC to DC power converter. Within the power supply, conversions of AC to DC then to high frequency AC, then to high voltage DC take place. Typical SLM power supplies comprise a few basic building blocks. These are: 1) AC to DC rectifier, 2) Power Factor correction boost circuitry 3) High frequency quasi-resonant inverter, 4) High voltage transformer and rectifier circuits, and 5) Control and monitoring circuits. The following is a brief description of each building block. 4.3 High Voltage Circuits The high voltage transformer is a step-up type. The secondary of the high voltage transformer is connected to the high voltage output circuit. The output circuit will vary depending upon the rated output voltage and a full wave Cockroft-Walton multiplier is used. A feedback signal is generated by the high voltage resistor divider. This feedback signal is sent to control circuits to provide voltage regulation and monitoring. A current sense resistor is connected at the low voltage end of the output circuit. The circuit sense signal is sent to the control circuits to provide current regulation and monitoring. 4.1 Power Factor and Associated Circuits The SLM series can operate from 90 - 265Vac, for the 300Watt model and 180 –264Vac for the 600 and 1200Watt models. The input voltage is connected via a typical IEC 320 type input connector. An internal EMI filter and fuse housing is an integral part of the SLM module. The input circuits actively correct the power factor. The high voltage output is connected to the output limiting resistors. These resistors limit the peak surge current in the event an arc or discharge occurs. The limiting resistor output is connected to the output connector provided. The input line voltage is applied to a current limit device to reduce the initial inrush current. The input line voltage is converted to a 400Vdc voltage via an active PFC Converter. WARNING WARNING THE HVPS IS DESIGNED TO HANDLE AN ARC RATE OF 1 ARC PER SECOND, EXCEEDING 1 ARC PER SECOND COULD CAUSE DAMAGE TO THE HVPS. HVPS FAILURE CAUSED BY EXCESSIVE ARC WILL NOT BE COVERED UNDER THE WARRANTY. The energy levels used and generated by the power supply can be lethal! Do not attempt to operate the power supply unless the user has a sufficient knowledge of the dangers and hazards of working with high voltage. Do not attempt to approach or touch any internal or external circuits or components that are connected or have been connected to the power supply. Be certain to discharge any stored energy that may SLM MANUAL 13 118073-001 Rev C 4.4 Control Circuits Control circuits are used for regulation, monitoring, pulse-width, control, slow-start and inhibit control. Feedback signals are calibrated and buffered via general purpose OP-AMPS. Pulse width control is accomplished by a typical PWM type control I.C. Logic enable/disable is provided by a logic gate I.C. Regulators generate ± 15Vdc and 10Vdc. DSP based control circuitry provides excellent regulation, along with outstanding stability performance 4.5 Options Due to the variations of models and options provided in the SLM series, details of actual circuits used may differ slightly from above descriptions. Consult Spellman’s Engineering Department for questions regarding the principles of operations for the SLM series.

See section 6.0 for the syntax of the serial interface protocol. The programmer should also review section 4.3 for programming considerations for the USB interface as the code is nearly identical for the RS-232 interface. All software that addresses the RS-232 interface must adhere to the following parameters: • A default Baud rate of 115.2K bps • No Parity • 8 Data Bits • 1 Stop Bit • No handshaking The Baud rate can be changed to 115.2K ,57.6k,38.4k,19.2k or 9600 bps and stored in the unit. 4.1.1 Enabling Communications Objects in Visual Basic for RS-232 Communications in Microsoft Visual Basic 6.0 are directed to a control that abstracts the port. In the case of serial and USB we need Microsoft Comm Control 6.0. To enable this in your VB 6 project, go to: Project -> Components Then in the list make sure that Microsoft Comm Control 6.0 has a check next to it. The Comm Control Object should then appear in your toolbox. It will have an icon of a telephone and will be named: MSComm. This can be dragged and dropped into your application. You will then need to set the object’s properties. 4.1.2 Configuring Communications in Visual Basic for RS-232 In order to configure the MSComm Object, first you must initialize it in the Object properties: Settings Handshaking 115200,n,8,1 0 – comNone The application can be set to either default to a specific COM Port or the End User can be allowed to choose one for the particular PC. 118080-001 REV A Page 10 of 95 For the “Default” scenario, include the following commands in the Form_Load() routine: MSComm1.CommPort = portNumber MSComm1.PortOpen = True For the “Choice” scenario, place the above two commands in a selectable menu item. 118080-001 REV A Page 11 of 95 4.2 ETHERNET The SLM contains an embedded diagnostic web server that can be accessed through any standard web browser by browsing to the SLM’s IP address.

Figure 10 - Web Page 2 – License Agreement 118080-001 REV A Page 14 of 95 4.2.2.3 Web Page 3 - Monitor and Control Applet 4.2.2.3.1 Requirements The Monitor and Control Applet is a java “applet” (“small java application” specifically written to be embedded in a web page and invoked from a browser) that requires an Internet browser with an installed JVM (Java Virtual Machine). The password for the applet is: shvapplet. We have tested under Internet Explorer 5 and 6, Microsoft JVM 5 and Sun JVM versions 1.6 and higher. 4.2.2.3.2 Description of Monitor and Control Applet Figure 11 displays an example of an embedded monitor and control application. Figure 11 - Control and Monitor Applet 118080-001 REV A Page 15 of 95 View the screen as a “left” and a “right” with the right half containing status read from the SLM and the left half containing the values that are programmable by the user. For any programmable setting you click on the button to the left of the setting, which brings up the program set point screen. For example, click on the button labeled, ‘V’ to set the output voltage set point. Refer to figure 12. 4.2.2.4 Program Set Point Screen . Figure 12 - Program Configurable Values Screen The field is the scaled value or real world value. Enter the desired set point level within the shown range. The user can then click Apply to send the set point to the SLM and remain in the set point screen, or click OK to send the set point and close the set point entry window. The user may also click on Cancel to close the window without sending any changes. To reset the Total hour On meter to zero via the Applet a password is required.The password is “SHV_Reset” 4.2.2.5 Java Warning Messages You may notice a message at the bottom of all dialog windows that are displayed from the SLM Control and Monitor Applet. The wording may vary slightly depending on the JVM version but on some the message is “Java Applet Window”. This message informs the user that the dialog window was generated by an applet. The design philosophy for the JVM was for secure computing, so the origins of new windows are supposed to be as obvious as possible. 118080-001 REV A Page 16 of 95 4.2.2.6 “Tabs” on Applet The user can view and set operating parameters of the applet or network configurations of the SLM or view firmware version information by changing tabs. 4.2.2.7 User Settings Figure 13 – User Setting The User Settings tab allows the user to set firmware configurable options, as shown above. After making changes to the options, click on the “Click to Apply Changes” button. 118080-001 REV A Page 17 of 95 4.2.2.8 Fault log Figure 14 – Fault log Fault log displays faults with their date and time. 118080-001 REV A Page 18 of 95 4.2.2.9 About Displays version information and model number. Figure 15 – About 118080-001 REV A Page 19 of 95 4.2.2.10 Turning the SLM HVOn/Off and Connection Status Please refer to Figure 11, the Monitor and Control Applet. Setting Name Range Values Local/Remote Local mode/Remote mode HV On/Off Interlock Open/Closed Fault Status OK/Fault Connection Status Connected/No Data Received/Disconnected Unlike the controls we previously discussed at the top of the screen which required a separate dialog screen to enter values, these are controlled by a button. For example, an On/Off button controls the HV. When HV is on, the Control is labeled “Click to Turn HV Off”. When HV is off, the control is labeled “Click to Turn HV On”. Thereby handling the two distinct states. Notice that at the very bottom of the screen is a text field that displays the current connection status, which as mentioned above is one of three values. “Connected” is displayed when there exists a valid TCP/IP session connecting the SLM and the Applet and data is being received by the applet from the SLM. The next state is “No Data Received” which is when there is still a valid connection but no responses have been received from the SLM for 2 seconds. Lastly, the text field displays “Disconnected” when the TCP/IP session has been disconnected. To operate the UUT using the Computer interface the UUT must be set to Remote Mode by Clicking “Click to Set Remote, the SLM Applet automatically sets the unit to Remote mode upon connecting. When the Applet is first started and anytime the “Click To Connect” button is clicked there is a 5 second delay as the Applet starts up the threads necessary for communication between it and the SLM. 4.2.3 Direct Connection between the SLM and a Computer A direct Ethernet connection between the SLM and the computer requires an RJ45 crossover cable. The end connectors will look identical to a “normal” RJ45 connector but the colors of some of the wires in the connectors will be “reversed”. Hold up the two ends of the RJ45 cable and look at the color of the wires from left to right. They should differ on the two connectors. 118080-001 REV A Page 20 of 95 When direct connecting the SLM to a computer using a crossover cable over Ethernet they are essentially participating in a private network. As such you need to pick two valid IP addresses, one for each device. The table below illustrates that not all IP addresses are actually valid IP addresses. For example, IP addresses beginning with 127 are not valid. Class Address Range A 1.0.0.0-126.255.255.255 B 128.0.0.0-191.255.255.255 C 192.0.0.0-223.255.255.255 4.2.3.1 Configuring the Computer for Direct Ethernet Connection As mentioned above both the IP Address and Subnet Mask need to be configured. In our environment computers normally are assigned IP addresses dynamically, using DHCP. We need to change this and assign the IP Address statically to the one we have selected. Here are the steps on Windows XP. On the desktop right click on “My Network Places” and select properties at the bottom of the menu. Figure 16 – Right Click on Desktop 118080-001 REV A Page 21 of 95 Figure 17 – Select Properties After selecting properties you are brought up to the screen below (Figure 18). You must RIGHT CLICK and select Properties on Local Area Connection, and not double click which will display a window similar to figure 19. Figure 18 – Here you must Right Click and Select Properties 118080-001 REV A Page 22 of 95 Figure 19 – Local Area Connection Properties Now you must select “Internet Protocol (TCP/IP)” and click on the Properties button to be brought to figure 20. Lastly you must disable any firewall software you have running. If you are running a proxy server for Internet access, you must also disable the proxy client. Disabling this also requires a reboot. 118080-001 REV A Page 23 of 95 Figure 20 – TCP/IP Properties 4.2.3.2 Testing a Direct Connection You can use the program “Ping” to test a network connection between the computer and the SLM. “Ping” is a command line tool so we will need to bring up a command prompt. Under Windows NT, 2000 and XP the name of this command is “CMD”. Under Windows 98 the name of this command is “Command”. To do this, click on Start->Run->Cmd Then on the command line type PingFor example Ping 192.168.1.4 If the SLM is found at the specified IP address, the Ping command will respond with a report that is similar to: Pinging 192.168.1.4 with 32 bytes of data: 118080-001 REV A Page 24 of 95 Reply from 192.168.1.4: bytes=32 time<1ms TTL=64 Reply from 192.168.1.4: bytes=32 time<1ms TTL=64 Reply from 192.168.1.4: bytes=32 time<1ms TTL=64 Reply from 192.168.1.4: bytes=32 time<1ms TTL=64 Ping statistics for 192.168.1.4: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 0ms, Average = 0ms 4.2.4 Configuring the SLM For a Local Area Network (LAN) If you have chosen to place the SLM onto your local area network you will need: • A CAT5 network patch cable to physically connect the SLM to the LAN • A static IP address to assign to the SLM. Remember that even if the IP address you have selected is in general a valid IP address it needs to be valid for your LAN (local area network). Otherwise the device will not be accessible from an Internet browser or Ping. 4.2.4.1 Configuring the Network Settings from the Monitor and Configure Applet The network settings are configurable from the Network Settings tab, refer to figure 21. 118080-001 REV A Page 25 of 95 Figure 21 - Configure Network Settings The settings that can be changed are the: • Device Name • IP Address • TCP Port • Subnet Mask Once the Apply button is clicked on the network settings screen, the network component of the SLM is configured, rebooted and the applet is disconnected from the SLM. You must type the NEW IP address into a web browser to bring up a new instance of the applet to monitor and control the SLM after reconfiguring it. This may also 118080-001 REV A Page 26 of 95 require reconfiguring the host computer with the correct host IP address, subnet mask, and TCP port. The device name does not affect the operation of the SLM; it is simply a way for the user to differentiate multiple units on the same network. Depending on the type of network you are attaching the SLM to, you may need to configure the host PC’s IP address and subnet mask as shown in section 4.2.3.1. You can also test a network connection to the SLM by following the instructions listed in section 4.2.3.2 . 4.2.5 Enabling Communications Objects in Visual Basic for Ethernet Communications For Ethernet communications, we need Microsoft Winsock Control 6.0 and SP5. To enable this in your VB 6 project, go to: Project -> Components Once selected in your toolbox, you will have an icon of two computers linked together and will be named: Winsock. This can be dragged and dropped into your application. Then set the object’s properties. 4.2.6 Configuring Communications in Visual Basic for Ethernet In order to configure the Winsock Object, you must make the following initialization in the object’s properties: Protocol 0 – sckTCPProtocol Then, in the application code, include the following commands: tcpClient.RemoteHost = host tcpClient.RemotePort = portNumber tcpClient.Connect For further information regarding the use of the above commands, please refer to your Visual Studio Help File. 4.2.6.1 Data Output Example MSComm1 is both the serial and USB port. TcpClient is the Ethernet port. 118080-001 REV A Page 27 of 95 If (portType = "ethernet") Then tcpClient.SendData (str) Else MSComm1.InBufferCount = 0 On Error GoTo done MSComm1.Output = str done: tmrOpenClose.Enabled = True End If 4.2.6.2 Data Input Example If (portType = "ethernet") Then Do DoEvents ............................................................................................................................. .................................................................................................. ttcpClient.GetData temp$ str = str + temp$ Loop Until InStr(str, Chr(3)) Or Timer - t1 > 1 On Error Resume Next Else Do DoEvents If MSComm1.InBufferCount > 0 Then str = str & MSComm1.Input End If Loop Until InStr(str, Chr(3)) Or Timer - t1 > 1 If InStr(str, Chr(3)) > 0 Then tmrOpenClose.Enabled = False End If End If 118080-001 REV A Page 28 of 95 4.3 USB The USB interface makes use of a standard ‘command/response’ communications protocol. See section 6.0 for the syntax of the serial interface protocol. The USB interface is accessed through a Windows USB Human Interface driver (HID). 4.3.1 USB Driver Installation The HID driver is a Windows driver installed with the operating system. To determine if the driver had been acquired open the System properties window selecting the Control Panel System Properties. Figure 22 – System Properties Then select Device Manager and expand the Human Interface Devices. View the properties of the USB Human Interface Device icon and verify that Spellman USB HID appears in the Location section. 118080-001 REV A Page 29 of 95 Figure 23 – Device Manager showing USB HID 4.3.2 USB and EMI The USB protocol utilizes a heartbeat signal from each client device back to the host (PC). If the heartbeat is interrupted due to radiated or conducted transient noise, it is possible that the host may lose connection with the client. This can cause problems with data transfers over the USB cable. The DXM when used in combination with the HID Windows driver makes it possible for the host to renumerate the client connection and reestablish communications. This is providing the control application implements a method of timeout and retry. NOTE: If an EMI disruption occurrs the DXM will continue to renumerate until a connection with the GUI is re-established. 118080-001 REV A Page 30 of 95 4.3.3 Enabling Communications Objects in Visual Basic for USB The dynamic link library USB_dll.dll will be provided which needs to be added to the project. The library has three functions that can be called from the VB code. The three functions are: • FindTheHid – finds the connection with the correct VID, PID and Serial Number • WriteReport(str) – Writes a string to the connected HID interface • ReadReport() – Returns a string from the connected HID interface 4.3.4 Configuring Communications in Visual Basic for USB To use the USB_dll.dll in VB the following statements are needed. Dim usb As usbDll Dim MyDeviceDetected As Boolean Set usb = New usbDll Using this statement determines whether a connection is present. MyDeviceDetected = usb.FindTheHid If MyDeviceDetected is true then the connection is present. 4.3.5 Software Considerations for USB Reconnection The following Visual Basic code snippets are presented as a guideline for implementation with revision C and higher assemblies. 4.3.5.1 Recognize partial, corrupt, or absent data 1: temp2$ = inputInputString 2: If temp2$ <> "" Then 3: btn_UPDATEDATA.Value = False 4: CommStatusFlag = True 5: CommaPos = InStr(Start, temp2$, Comma, vbTextCompare) 6: ' Channel 0 7: On Error GoTo endhere 8: AmbTemp = Mid(temp2$, Start, (CommaPos - Start)) Please note that even though we have guarded against no data, in line 2, we still need to guard against bad data, in this case no comma, on line 8. If there is no comma, we wind up passing a negative value to Mid, which is an error, that we should trap for. 118080-001 REV A Page 31 of 95 4.3.5.2 1: Do 2: 3: 4: 5: 6: 7: 8: 9: 10: Retrieve data only if it exists DoEvents If MSComm1.InBufferCount > 0 Then str = str & MSComm1.Input End If Loop Until InStr(str, Chr(3)) Or Timer - t1 > 1 'str = str & MSComm1.Input If InStr(str, Chr(3)) > 0 Then tmrOpenClose.Enabled = False End If Notice that in line 3 we check for the existence of data before we extract data from the USB port. Normally, if there is no data, line 4 would append an empty string. However, during a noise event, retrieving data without first checking the existence of data could hang. 4.3.5.3 Example Output Routine Notice that on line 13 we register an error handler in case the port is invalid because we have closed it in another routine. Notice that on line 16 we start a timer. When we output data on the port we start a timer to keep track of incoming data. If we get no incoming data it means that communications have been interrupted. 1: Private Sub outputOutputString(outputString As String) 2: Dim str As String 3: str = ProcessOutputString(outputString) 4: StatusBar1.Panels(4).Text = "TX: " & str 5: 'StatusBar1.Panels(3).Text = "RX: Waiting" 6: If (portType = "ethernet") Then 7: tcpClient.SendData (str) 8: ElseIf (portType = "USB") Then 9: usb.WriteReport (str) 10: Else 11: MSComm1.InBufferCount = 0 12: 13: On Error GoTo done 14: MSComm1.Output = str 15: done: 16: tmrOpenClose.Enabled = True 17: End If 18: End Sub 118080-001 REV A Page 32 of 95 4.3.5.4 Example Input Routine Notice on line 26 we check for data first before extracting data from the input. Then if we have actual data we turn off the timer. Otherwise the timer routine toggles the port open/close. 1: Private Function inputInputString() As String 2: Dim str As String 3: Dim t1 As Single 4: Dim temp$ 5: 6: Dim stra As String Dim stri(300) As String 7: t1 = Timer 8: 9: If (portType = "ethernet") Then 10: Do 11: DoEvents 12: tcpClient.GetData temp$ 13: str = str + temp$ 14: Loop Until InStr(str, Chr(3)) Or Timer - t1 > 1 15: On Error Resume Next 118080-001 REV A 16: 17: 18: 19: 20: 21: 22: ElseIf (portType = "USB") Then Do DoEvents stra = usb.ReadReport str = str & stra 'str = str & ReadReport Loop Until InStr(str, Asc(3)) Or Timer - t1 > 0.09 23: 24: 25: 26: 27: 28: 29: 30: 31: 32: 33: 34: 35: 36: 37: Else Do DoEvents If MSComm1.InBufferCount > 0 Then str = str & MSComm1.Input End If Loop Until InStr(str, Chr(3)) Or Timer - t1 > 1 If InStr(str, Chr(3)) > 0 Then tmrOpenClose.Enabled = False End If frm_EXTRAS.txt_MSCOMMBUFF.Text = str tmr_COMMWDT.Enabled = True On Error Resume Next Page 33 of 95 38: End If 39: StatusBar1.Panels(3).Text = "RX: " & str 40: inputInputString = str 41: tmr_RCVTIMER.Enabled = True 42: End Function 4.3.5.5 Example Timer Routine: Toggle Port State This is the timer routine in which the open/closed state of the port is toggled. If communications are interrupted, the USB device will reregister itself with the OS (vendor term: renumeration). Once this happens, re-opening the port will enable communications. Until the re-registration happens, open operations will fail. Notice line 5 where we register an error handler. 1:Private Sub tmrOpenClose_Timer() 2: If MSComm1.PortOpen = True Then 3: 4: MSComm1.PortOpen = False 5: On Error GoTo done 6: MSComm1.PortOpen = True 7: done: 8: tmrOpenClose.Enabled = False 9: End If 10: 11: End Sub 4.3.5.6 Example Timer Routine: Port Reconnection This is another timer routine whose purpose is to turn the port on if it is off. Notice that in line 8 an error handler is called because if the device has not re-registered itself with the OS, an error will be raised. 1: Private Sub tmr_COMMWDT_Timer() 2: 3: tmr_COMMWDT.Enabled = False 4: 5: If CommStatusFlag = True Then 6: 7: If MSComm1.PortOpen = False Then 8: On Error GoTo done 9: MSComm1.PortOpen = True 10: done: 11: End If 12: 13: ElseIf CommStatusFlag = False Then 14: 118080-001 REV A Page 34 of 95 15: If MSComm1.PortOpen = False Then 16: 17: MSComm1.PortOpen = True 18: Else 19: MSComm1.PortOpen = False 20: End If 21: 22: End If 4.3.5.7 Data Parsing Example Here we have an example of a code that parses incoming data. Notice that it makes use of our generic input and output routines. The important consideration is to gracefully handle corrupted input data after a noise event. In this case we may get data, so a test against empty string returns false, but we may not get commas in the correct place. Notice that we register an error handler on line 26 so that the mid function, which would raise an error when given a negative number, is handled. 1: Private Sub btn_EMI_Click() 2: Dim temp2$ 3: Dim Response1$ 4: Dim Response2$ 5: Dim number$ 6: Dim Comma 7: Dim CommaPos 8: Dim Start 9: Dim ODATA$ 10: 11: Comma = "," 12: Start = 5 13: 14: If tmr_RCVTIMER.Enabled = True Then tmr_RCVTIMER.Enabled = False 15: If tmr_NETRCVTMR.Enabled = True Then tmr_NETRCVTMR.Enabled = False 16: 17: If AutoUpdate = True Then 18: tmr_UPDATE.Enabled = False 19: End If 20: 21: number$ = "15," 22: outputOutputString (number$) 23: 24: temp2$ = inputInputString 25: CommaPos = InStr(Start, temp2$, Comma, vbTextCompare) 118080-001 REV A Page 35 of 95 26: On Error GoTo endhere 27: Response1$ = Mid(temp2$, Start, (CommaPos - Start)) 28: 29: 'With a 5v reference: 30: ODATA$ = Format(str(Response1$ * 0.0004884), "0.##0") 31: 32: txt_DACB.Text = ODATA$ + " mA" 33: frm_RAWDATA.txt_RAWDACB.Text = str(Response1$) 34: txt_DACB.BackColor = vbWhite 35: CommStatusFlag = True 36: endhere: 37: 38: If portType = "ethernet" Then 39: tmr_NETRCVTMR.Enabled = True 40: Else 41: tmr_RCVTIMER.Enabled = True 42: End If 43: 44: If AutoUpdate = True Then tmr_UPDATE.Enabled = True 46: End Sub 118080-001 REV A Page 36 of 95 5.0 ETHERNET COMMANDS 5.1 TCP/IP FORMAT Each Ethernet command will consist of a TCP/IP header followed by the required data bytes.
