  • Page 9: Vme Dlan Interface Module Functions

    VME DLAN Interface Module Functions The VME DLAN Interface module can operate as either a DLAN or DLAN+ controller. However, a single module can not be both a DLAN and DLAN+ controller at the same time. If the application requires both DLAN and DLAN+ devices, two DLAN Interface modules must be used.

  • Page 11: Address Select Jumpers

    Address Select Jumpers The address select jumpers, JP1 through JP4, are used to select the VME base address that the VME DLAN module will respond to in VME short non-privileged mode. See chapter 2, section 1 of this manual for details.

  • Page 12: Dlan Network Connector

    DLAN Network Connector This eight-pin connector provides a means of connecting the DLAN Interface module to the DLAN or DLAN+ network. A connector on the cable from the DLAN network connection block mates to the connector on the module. DLAN Configuration Jumpers These jumpers are used to configure the network connection when the Network Type is specified as DLAN.

    Before you can begin the installation procedure, you must have the following equipment and software: A VMEbus based computer system that includes (at least) a VME rack, power supply, and CPU module. One or more VME DLAN Interface modules. An application development platform and tools for the VME CPU. GFK-1044A...

    Then, the DLAN Interface module must be installed in a VME rack. Overview Each VME DLAN Interface module must reside in the same rack as the VME CPU. The following illustration shows one possible system configuration for installing a DLAN Interface module in a VME rack.
  • Page 15 a47042 Figure 2-2. Address Selection Jumpers There are 16 possible ways to set the four jumpers, and each one provides a unique range of short non-privileged addresses for the module. Table 2-1 shows the address range for each setting. Table 2-1. Jumper Settings for Short Non-Privileged Address Range Short Non-Privileged Address Range (Hexadecimal)

    1. Power off the VME system. 2. Locate the desired slot. 3. Remove the VME DLAN Interface module from the shipping carton, but leave it in its anti-static plastic bag. Touch an exposed metal surface of the VME rack to discharge any electrostatic charge you may have picked up.

  • Page 17: Section 2: Dlan Jumper Configuration

    Section 2: DLAN Jumper Configuration DLAN Configuration Jumpers When a DLAN network (rather than DLAN+ network) is used, jumpers on the DLAN daughter board must be used to configure the network connection. This section describes how to set the jumpers. If you are using a DLAN+ network, skip this section. Figure 2-3 is an enlarged view of the DLAN configuration jumpers shown in Figure 1-1.

  • Page 18: Selecting The Dlan Network Type

    If the DLAN modules is powered on while connected to an optically isolated network and jumpers JP2, JP3, and JP4 are set to the 2–3 position, the external isolated power supply for the isolated network will be damaged. VME DLAN/DLAN+ Interface Module User’s Manual - August 1995 GFK-1044A...

  • Page 19: Selecting Rs-485 Termination Resistors

    Selecting RS-485 Termination Resistors If the RS-485 network is selected, the drop at each end of the network cable should have the termination resistors IN. This is true for all drop types, both DLAN modules and drives. Adding additional termination resistors will improve the signal to noise ratio of RS-485 networks, but more than five sets of termination resistors will overload the drivers.

  • Page 20: Section 3: Initializing The Vmebus Interface

    Section 3: Initializing the VMEbus Interface Each VME DLAN module must be initialized by writing to its VMEbus memory from the VME CPU or other VME module before the DLAN module can be used. This initialization must occur each time a rack containing a DLAN module is powered on.

  • Page 21: The Initialization Process

    VME short non-privileged mode, but only the first 2K (800 hexadeci- mal) bytes of dual-ported memory may be accessed in this mode. Accordingly, the principal use of short non-privileged mode with VME DLAN modules is to detect their presence and write initialization data to them.
