    ISA backplane. Multiple slave-configured G4LC32ISA-LT processors, each with their own I/O, may be installed in a single PC. As a slave, the only resource the G4LC32ISA-LT needs from the ISA bus to run is power. Thus, you may reset the PC, and the G4LC32ISA-LT will continue to operate.
  • Page 8: I/O Units

    The use of flash technology allows a user to remotely download new kernels offered by Opto 22. This avoids the need to go to the actual G4LC32ISA-LT location to download a new kernel that offers features required for a given application.

  • Page 13: Quick Start

    QUICK START OVERVIEW This chapter provides a brief explanation of how to get the G4LC32ISA-LT up and running on a PC using a hard-wired RS-485 host port connection to I/O units. If you are installing the G4LC32ISA-LT in an environment that is networked, uses multiple hosts, or uses modems, refer to Chapter 3 for detailed instructions.
  • Page 14: Checking Configuration Jumpers

    QUICK START CHECKING CONFIGURATION JUMPERS The G4LC32ISA-LT is configured by the factory for connection to a host PC’ s ISA bus. Its two serial ports are default-configured for RS-485 communication at 115.2 KBd, and are biased and terminated. The G4LC32ISA-LT’ s default address is 1 and the default communication mode is binary.

    QUICK START CONNECTING THE BATTERY To save battery power, the G4LC32ISA-LT backup battery is not connected at the factory. Refer to Figure 2-2 to determine a suggested battery location and its connection to the G4LC32ISA-LT. For detailed information on connecting the battery, see Chapter 3, “Connecting the Backup Battery.”...

    This chapter expands upon the quick start information in Chapter 2 with detailed instructions on installing and configuring the G4LC32ISA-LT. After unpacking the G4LC32ISA-LT, review the packing list in Chapter 2 to ensure that all components are included. You may then proceed through the installation procedures below, as detailed in this chapter: 1.
  • Page 18: Setting Configuration Jumpers

    This section describes these configuration jumpers. Refer to Figure 3-1 for the location of the G4LC32ISA-LT jumpers. Table 3-1 describes the use and default settings of most jumpers. “In” means a jumper is installed and “out” means a jumper is not installed.

    INSTALLATION AND SETUP The G4LC32ISA-LT is shipped from the factory with all B and C group jumpers installed. This setting is for a G4LC32ISA-LT in a 2-wire or 4-wire RS-485/422 communication link located at the beginning of the physical link. These jumpers bias and terminate the TX/RX± 2-wire, RX± 4-wire, and IRQ communication lines.
  • Page 23: Connecting The Backup Battery

    *Note: These settings are different than the Windows default settings for COM3 & COM4. CONNECTING THE BACKUP BATTERY The G4LC32ISA-LT uses a RAM backup battery. This 3.6-volt lithium battery features a shelf life of up to 10 years and an operational life of two to five years.
  • Page 24: Installing The G4Lc32Isa-Lt

    Note: Be sure to configure the jumpers and connect the G4BATT32 before installing the card. The general procedure for installing the G4LC32ISA-LT card is as follows: 1. Find an unoccupied 16-bit ISA expansion slot in the computer. 2. Remove the expansion slot cover if one is installed.
  • Page 25: Connecting To A Host Pc, Modem, Or Other Device

    RS-485/422 COM0 and COM1 configured ports may be used as a serial link to connect to Opto 22 I/O units. The G4LC32ISA-LT can be separated by up to 3,000 ft. from I/O units or controllers. (An AC38 repeater enables even longer separation distances.) This is accomplished via a single shielded twisted-pair cable that provides communication over an RS-485/422 serial data bus.
  • Page 26: Wiring

    Use the G4LC32ISA-LT connectors provided and refer to the configuration label for wiring information. The following sections describe wiring for the serial ports found on the G4LC32ISA-LT. Use Tables 3-4 and 3-5 as references for wiring the pluggable, 7-terminal, serial port connectors shown in Figure 3-9:...

    Refer to your modem documentation for detailed wiring information, possible jumper configuration, and initialization setup. You may also wish to refer to Opto 22’ s communication application notes, available through Opto 22’s Bulletin Board Service (see Appendix E for details).
  • Page 31: Connecting To I/O Units

    The built-in RS-485/422 COM0 or COM1 port can be used as a serial link to communicate with digital or analog remote I/O units. One method for doing this is to use an Opto 22 P/N G4IOR I/O remote interface as illustrated in Figure 3-14. This method allows the use of Opto 22 standard I/O equipment (G4 panels, cables, etc.).
  • Page 32 Another method for using the RS-485/422 COM0 or COM1 port as a serial link (remote) is to use an Opto 22 P/N SBTA to install I/O units. This allows you to accommodate your own installation practices, application requirements, and cables. Simply mount your I/O units throughout your installation and daisy chain the communication cable between them.

  • Page 36: Optocontrol Software

    Before writing OptoControl strategies for the G4LC32ISA-LT, you must inform OptoControl about the I/O connected to the G4LC32ISA-LT. This means you will first need to decide how many I/O points of each type (digital and analog) are required for your application.

    G4LC32ISA-LT in RAM, downloaded and debugged, and then stored in flash memory. If the G4LC32ISA-LT has been set up to boot automatically from flash memory, the OptoControl strategy stored in flash will be executed upon power up.
  • Page 38: Updating The G4Lc32Isa-Lt Firmware

    Each processor has a boot loader permanently stored into a non-erasable portion of its flash memory. This boot loader enables a user to download a new kernel as Opto 22 makes new kernels available, even if the existing kernel has been lost.
