C H A P T E R 9 Downloading Events Overview In this chapter The PX5 allows users to download, archive and view event data in a computer. This section discusses the external communications device and software applications necessary to transfer and store PX5 data files to a computer.
External Communication Interface External Communication Interface To download events from the PX5 through the optical port, you must have the Isolated Communications following: a personal computer or laptop with Windows® operating system with either Module RS232 serial port or network adapter, NodeLink®, and the appropriate Isolated Communications Module assembly as described below. The Isolated Communications Module assembly consists of two parts: 1.
CH 9/ Downloading Events The following procedure and diagram describe how to connect the PX5 to a computer Connection setup via RS232 via RS232. Once the physical connection is done, see Chapter 4 Instrument Settings Communications on page 4-10 for instructions on how to enable the PX5 settings to communicate with external devices. 1. Connect one end of the fiber optic cable (P/N 900406) into the Fiber Optic Serial Data Port located on the left side panel of the PX5. 2.
External Communication Interface, continued Connection setup via USB The following procedure and diagram describe how to connect the PX5 to a computer via USB. Once the physical connection is done, see Chapter 4 Instrument Settings Communications on page 4-10 for instructions on how to enable the PX5 settings to communicate with external devices. 1. Connect one end of the fiber optic cable (P/N 900406) into the Fiber Optic Serial Data Port located on the left side panel of the PX5. 2.
CH 9/ Downloading Events Connection setup via Ethernet The following procedure and diagram describe how to connect the PX5 to a computer via Ethernet. Once the physical connection is done, see Chapter 4 Instrument Settings Communications on page 4-10 for instructions on how to enable the PX5 settings to communicate with external devices. 1. Connect one end of the fiber optic cable (P/N 900406) into the Fiber Optic Serial Data Port located on the left side panel of the PX5. 2.
External Communication Interface, continued Connection setup via Modem When configuring both the PX5 and NodeLink® for modem communications, keep in mind that the PX5 uses a fiber optic serial port in order to maintain electrical isolation. This means that there are no control signals available to a modem to use for handshaking and flow control. It is highly recommended that identical modems be used on the PX5 and the computer.
CH 9/ Downloading Events Connection setup via Modem (continued) NodeLink® uses Windows® TAPI when accessing modem communications resources. The assumption is that the Windows® modem to be used for PX5 communications has been properly installed prior to executing this procedure. If the modem is not on, or was not on when Windows® was started, it may be necessary to turn the modem on and restart Windows®. Windows® searches for installed serial modems at startup.
External Communication Interface, continued Connection setup via Modem (continued) Back at the PX5, the last step in configuring the modem communications is to modify the modem initialization string to match the modems and chipsets being used. The goal is to configure for the following: • Restore factory settings. • Set auto-answer to answer on one or two rings (more than two rings are allowed but at some point the number of rings may start to conflict with NodeLink® timeouts).
CH 9/ Downloading Events The following is the AT initialization string for a modem using the Agere (Lucent) Modem initialization chipset: string command (continued) AT&F;S0=2;&K0;%E0;S30=6 Where AT is the modem attention command. &F instructs the modem to restore factory configuration. S0=2 turns auto-answer on and sets the number of rings to answer to two. &K0 turns flow control off. %E0 disables baud rate fall back/fall forward. S30=6 sets a 60 second inactivity modem hang up timeout.
® Downloading Events via NodeLink Downloading Events via NodeLink® NodeLink® application NodeLink® is a Windows®-based program enabling the user to download, archive and visualize (using DranView®) event-type data from a variety of Dranetz-BMI instruments including the PX5. Users are strongly advised to always keep their NodeLink® and PX5 programs current with the latest version released by Dranetz-BMI. NodeLink V2.6 or higher is required to download events from PowerXplorer PX5 firmware V1.10 or higher.
CH 9/ Downloading Events Viewing Events via DranView® DranView® with DranView® is an optional viewer and data analysis software. Data collected by the PX5 PX5 driver must first be transferred to a computer via NodeLink® so that they can be archived and/ or viewed using DranView®. Users are strongly advised to always keep their DranView® and PX5 programs current with the latest version released by Dranetz-BMI. DranView® is available in soft key version (without HASP) and in hard key version (with HASP).
® DranView with HASP DranView® with HASP DranView® system requirements Installation procedure The minimum system specifications for proper installation and operation of DranView® V5.x and DranView® V6.x are shown below. Users are strongly advised to follow the recommended specifications for optimal DranView® operation. The recommended specifications are especially encouraged for use with instruments that allow generation of very large databases i.e. PX5, PG4400, and PP4300 Multi-DAQ.
CH 9/ Downloading Events Installation procedure (continued) STEP 2: FOR DRANVIEW V5.x: There are two types of HASP available: one which can be keyed to the USB port and another which goes into the Printer or Parallel port (see figure below). Depending on type of HASP, insert in the appropriate USB port or Printer/Parallel port in the computer. Align the HASP to the keyed port and push gently to lock it in place. Keep the HASP in the port while using the DranView® application.
® DranView with HASP, continued Installation procedure (continued) The table below shows the HASP ID labels that allow DranView® V6.x to work with the corresponding Dranetz-BMI product.

APPENDIX E/ Common Circuit Connections Verifying Voltage and Current Connections Introduction Correct voltage and current connection of single phase, split phase, or polyphase connections can be verified using phasor diagrams. Phasor diagrams are graphic representations that show the magnitude and angular relationship of voltage and current for each phase of a monitored connection.
Verifying Voltage and Current Connections, continued Incorrect current phasor diagram Phasor displays that show incorrect current probe connection can be corrected by reconnecting the probe so that the arrow on the probe handle points toward the load. PX5 is able to display diagrams of wiring configurations to assist users in the selection of circuit type appropriate for their application (see Chapter 5 Start Menu - Circuit Type Selection on page 5-12).
APPENDIX E/ Common Circuit Connections Single Phase Introduction When making voltage connections to a single phase circuit use channel A differential inputs as shown below.
