IB-23C003 INTRODUCTION SECTION 1 INTRODUCTION 1.1 DESCRIPTION The 1731N Mini Link with 1732N ICN Interface Board, Figure 1-1, provides a general purpose serial interface to MOD 30 and MODCELL instruments via the Instrument Communications Network (ICN). The 1731N Mini Link supports one ICN and the 1732N ICN Interface Board supports a second ICN.
IB-23C003 INTRODUCTION Physically the Mini Link is a PC/AT plug-in module which completely emulates the 1720N Communications Link (refer to IB-23C001) for up to two Instrument Communications Networks. The base configuration consists of: • An Integral PC/AT Serial Port (dedicated to the Mini Link) This serial port is DIP switch and jumper configurable to perform as an I/O-mapped memory device at I/O base addresses 000h through 3F8h.

IB-23C003 INTRODUCTION 1-8
IB-23C003 INSTALLATION SECTION 2 INSTALLATION 2.1 PREPARING THE PERSONAL COMPUTER Prepare your PC/AT as follows: 1. Turn off the system unit. 2. Turn off all external options (printer, display, etc.). 3. Unplug the system unit power cord from the electrical outlet. 4. Unplug any external options from the electrical outlet. 5. Remove the system unit cover mounting screws. 6. Remove the system unit cover. 7. Use Table 2-1 as a worksheet to record the types of devices already installed in your system unit.
IB-23C003 INSTALLATION 2.2 DETERMINING MINI LINK BASE ADDRESS/INTERRUPT LEVEL The total I/O address space required by the Mini Link is eight bytes in length. To guarantee operation, the selected base address must be at least eight bytes below any base address listed in Table 2-1. Generally, if there are no serial devices (mouse, modem, or RS-232 serial card) any of the standard COMx locations can be selected. These addresses have been reproduced in this document. See the Section 2.
IB-23C003 INSTALLATION 2.4 SWITCH AND JUMPER SETTINGS This section contains a brief description of the Mini Link switches and jumpers with an application table for each. A quick reference table of all switches, jumpers, and their functions is in Appendix A. 2.4.1 Serial Ports The Mini Link has two serial ports. Each serial port can be configured with an independent baud rate and CTS signal for access by two controlling consoles.
IB-23C003 INSTALLATION Hardware Interrupts and Polarity for PC/AT Serial Port The Mini Link hardware interrupt levels may be set as shown in Table 2-3. polarity is set as shown in Table 2-4. Interrupt Table 2-3. Mini Link Hardware Interrupts Jumper IN Interrupt Level W15 W16 W17 W18 W19 IRQ3 Y N N N N IRQ4 N Y N N N IRQ5 N N Y N N IRQ6 N N N Y N IRQ7 N N N N Y Table 2-4.

Clear-To-Send (CTS) for Serial Ports 1 and 2 Both the PC/AT and the External Serial Ports are outfitted with a CTS connection. In most cases, the CTS signal will not be needed.
IB-23C003 INSTALLATION 2.4.2 ICN ICN Isolation The Mini Link is fitted with Opto-isolation components capable of providing a minimum of 3000 VDC electrical insulation between the Instrument Communication Network and the PC/AT digital circuitry. This option is jumper-selectable by disabling the connection on W23 (remove this jumper to enable optical isolation). If optical isolation is enabled, the ICN connector must be fitted with a ground wire.
IB-23C003 PROGRAMMING MINI LINK INTERRUPTS SECTION 3 PROGRAMMING MINI LINK INTERRUPTS 3.1 GENERAL The IBM PC/AT has reserved hardware interrupts for common devices (printers, disk drives, etc.) within the interrupt level range (IRQ3-IRQ7) of the Mini Link. The Mini Link does not support the high order (8-15) interrupt request lines available on the IBM PC/AT. To operate the Mini Link on COM1, COM2, COM3 or COM4, the jumper settings from Tables 2-2, 2-3 and 2-4 must be employed exactly as they appear.
IB-23C003 PROGRAMMING MINI LINK INTERRUPTS Interrupt Service Routine Location It is the user's responsibility to install an Interrupt Service Routine at an appropriate memory location (according to the configured hardware interrupt) which does not interfere with concurrently operated software or hardware. In most cases, these interrupt service routines will be simple Transmit/Receive operations with user conditions determining success or failure of the routines.
IB-23C003 TROUBLESHOOTING THE MINI LINK SECTION 4 TROUBLESHOOTING THE MINI LINK 4.
IB-23C003 TROUBLESHOOTING THE MINI LINK 4.3 FROZEN DISPLAY/NO RESPONSE FROM PC KEYBOARD This type of problem is usually indicative of address or interrupt conflict on the personal computer I/O channel. You must establish a clear range of eight bytes I/O address space (in the range 000h to 3FFh) to successfully operate the Mini Link. In addition, there can be no other installed devices using the same interrupt request line as the Mini Link.
