  • Page 5: Introduction

    The MJ-5 Communications Module is installed in MJ-5 Tap Changer Control Panels. This allows you to easily network the control panels and other field devices to a remote terminal unit (RTU) or other supervisory device. An adapter kit is available for mounting MJ-5 Communications Modules in MJ-X Control Panels.

  • Page 6: Wire Transmission

    Figure 2-1: Fiber Optic Network 2.2 Wire Transmission The advantage of wire transmission is simple installation. The MJ-5 supports two popular wire interfaces: RS-232 and RS-485. The screw terminal block connector supplied with the module can be wired for either interface.

  • Page 7: Figure 2-4: Rs-485 Configuration - Loop Network

    MJ-5 Communications Module 2.2.2 RS-485 The maximum distance for RS-485 is 4000 feet, either from device to device or for an entire loop. The recommended cable for RS-485 is shielded, two twisted-pair, 22 AWG. This type of cable consists of jacketed wire that is twisted together and wrapped in a shield to prevent electromagnetic interference from affecting the data signal.

  • Page 8: Communication Protocols

    3 Communication Protocols The MJ-5 Control Panel is designed to be used in a network of intelligent power control devices communicating with a supervisory device or remote terminal unit (RTU). Each device on the network has a specific communications address assigned to allow messages to be directed to and from the device. Messages are transmitted from the RTU to all devices and only the device with the specified address will respond.

  • Page 9: Fiber Optic Cable Type

    / Att 5.1.2 Fiber Optic Connector The fiber optic cables (or “patch cords”) used with the MJ-5 Fiber Optic Communications Module must be terminated with ST style connectors and have a numerical aperture of 0.275 ± 0.015. (If pre-terminated cables are not used, follow the instructions supplied by the manufacturer to attach the connector to the fiber cable using the cable type recommended in section 7.1.)

  • Page 10: Rs-485 Twisted - Pair Cable

    5.2 RS-485 Twisted-pair Cable The following sections provide the information necessary to select and install cable between an MJ-5 Control Panel, RTU, and other field devices in an RS-485 network. 5.2.1 RS-485 Cable Type Listed in Table 7-1 are the cable characteristics necessary for proper electrical performance in an RS-485 communications network.

  • Page 11: Figure 5-4: Rs-485 Loop Topology

    Figure 7-2 shows the proper method for terminating the shield at the Communications Module connector. When the Communications Module is mounted in the MJ-5 Control Panel, it is grounded internally through the MJ-5 to the equipment ground. A separate connection to the equipment ground is not required.

  • Page 12: Rs-232 Connections

    Table 7-2 lists the connections that must be made to connect the RS232/485 interface to a personal computer, RTU, or other supervisory device. The MJ-5 Communications Module defaults to no-handshaking-required mode. However, the communications module asserts RTS while it transmits data, but the module will ignore the CTS input signal.

  • Page 13: Rs-232 Multi-Drop Wiring

    MJ-5 Communications Module Signal Return “RXD” is an input for Data Terminal Equipment (DTE) and an output for Data Communications Equipment (DCE). “TXD” is an output for the DTE and an input for the DCE. Personal computer serial ports are configured as DTE and the modems are configured as DCE.

  • Page 14: Communications Module Configuration (Reference 4.7)

    The < COMMUNICATIONS > menu of the MJ-5 Control Panel provides all the required communications configuration items for the communications module. Table 7-4 lists the communications menu items in the order in which they appear on the MJ-5 Control Panel; default settings are in bold.

  • Page 15: Communications Menu Item Descriptions

    NNN (range 000-255) 5.5.1 Communications Menu Item Descriptions Data Stat, DatPortBaud, Data Parity, and DataPortAddr These menu items apply only to the Data Port located on the front of the MJ-5 Control Panel, and do not require modification. Reg Id (Regulator Identification) This item allows you to uniquely identify each regulator in the system.
  • Page 16 Deadband Class 1, 2, or 3. The default value for each Deadband Class is 00.0 and the maximum value is 99.9. Comm Type This menu item displays which communication type is currently being used by the MJ-5. The user may select from Network, Fiber-serial, Serial, or RS-485. IP Config This menu item allows the user to enable or disable the IP Configuraion Selection.
  • Page 17 MJ-5 Communications Module This menu item displays the current IP Address. The user may change the IP Address by pushing the change/save button and using the up/down Navigations keys to increase or decrease each digit, or use the default address of 192.168.1.200...

  • Page 18: Troubleshooting Communications Problems

    The MJXplorer software is a menu-driven application program that allows interfacing to the MJ-5 Communications Module. Up to three MJ-5 units may be connected at a time. When connecting the Fiber Optic interface to MJXplorer, the auto repeat function must match the setting in the ConfigureConfigure MJXplorer menu. See section 4.3.1 for setting the Fiber Optic interface jumpers.

  • Page 19: Setting The Dnp Points

    Click the Setting button. Match the baud rate and parity between the computer and the panel. Choose the COM port your computer is using. Set Addressing to be Disabled (if MJ-5’s “DataPortAddr” setting is OFF). Click OK. Click the Send button.

  • Page 20: Selecting A Predefined Dnp Point Set

    When the MJ-5 Communications Module with firmware version 3.10 (initial release) or higher is interfaced with a MJ-5, you will be able to choose from a number of DNP point sets, including Set 7. Sets 8 through 15 are not defined at this time.
