CHAPTER 1 Introduction General Description The ACL IIR+TM (Advanced Communication Link II with RJ-12 connectors) is an intelligent expansion board that adds serial ports to an IBM PC/AT or compatible computer. An ACL IIR+ _ equipped computer, when used with a multiuser operating system, becomes a powerful tool as the host computer for a multiuser system. The ACL IIR+ relieves the host PC of communication responsibilities and supports up to eight serial devices. These include terminals, printers, plotters, modems, other computers and many other input/output devices. All ports provide asynchronous communications and use inexpensive RJ-12 connectors for quick and easy connections. Up to four standard ACL IIR+ boards may be used in a host PC, increasing your capabilities to 32 ports. With the installation of special PAL devices on the boards, the number of boards that can be used is limited only by the operating system, the availability of 16-bit PC slots and the power supply capacity. For a complete listing of ACL IIR+ specifications, please refer to Appendix A. Physical Description The Advanced Communication Link IIR+ consists of four separate items in one package: 1. ACL IIR+ User's Guide. This User's Guide is designed to be kept with the guide to operations manual of the host PC. 2. ACL IIR+ Device Driver (on 5.25- and 3.5-inch floppy diskette). These diskettes contain the device driver and support files for the ACL IIR+ Adapter Board. 3. ACL IIR+ Device Driver Installation Manual. 4. ACL IIR+ Adapter Board. System Requirements The following minimum system requirements are necessary for proper operation of the ACL IIR+: The host PC must be an IBM PC/AT or a 286-, 386-, or 486-based ISA-bus compatible. One full-length 16-bit expansion slot must be available for each ACL IIR+ adapter used. At least one IRQ line must be available if the device driver uses interrupts. Application Flexibility for Programmers The ACL IIR+ adapter is mainly a device to enhance communications, but it has the processing power to do other tasks as well. With additional programming by the user, the ACL IIR+ adapter can: Perform line discipline functions, such as local terminal emulations and character conversions. Perform file-oriented algorithms, such as data compacting, on an inter-channel basis. For example, a file can be received through one port, processed, then retransmitted through the same, different or multiple ports simultaneously. Reconcile format differences without host computer intervention, making it appear as if one device is directly compatible with another system, even though the actual format is different. For example, an intelligent repeater which converts ASCII to EBCDIC. If you need programming information, please call 1-800-STAR GATE (1-800-782-7428) and ask your Sales Representative for a copy of the ACL Family Technical Reference Manual. CHAPTER 2 Installation Handling Precautions The ACL IIR+ Adapter Board contains several components that may be permanently damaged if the adapter is handled improperly. To avoid accidental damage, follow these recommendations: Never insert or remove the board while power is applied to the computer. Once the computer power switch is shut off, wait at least 10 seconds for the power supply to discharge before inserting or removing the adapter. Before handling the board, touch a grounded object to discharge any static electricity that has built up on your body. Hold the board only by its edges. Hardware Configuration The information you will need to set up the hardware includes: From reading the software driver and application program documentation... check if the driver offers interrupt-driven and/or polled mode operation if given both, select the mode of operation by checking your application program for the best mode to use if you are using interrupt-driven operation, check which interrupts are offered by the driver. From your records and host PC documentation, find out: IRQs that are in use and no longer available to the ACL IIR+ driver, if you are using interrupts if the host PC uses a cache memory available I/O and memory ranges. ACL IIR+ Switches Before installing the ACL IIR+ board into your PC, you may need to confirm the default settings or make some adjustments to the switches shown below. You can set up and install multiple ACL family boards at the same time. Just make sure that their I/O addresses do not conflict.

The selections are listed as follows: ÚÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ¿ ON ³ ÚÄÄ¿ ÚÄÄ¿ ÚÄÄ¿ ÚÄÄ¿ ³ ³ ³ ³ ³ ³ ³ ³ ³ ³ ³ ³ ÃÄÄ´ ÃÄÄ´ ÃÄÄ´ ÃÄÄ´ ³ OFF ³ ³ ³ ³ ³ ³ ³ ³ ³ ³ ³ ÀÄÄÙ ÀÄÄÙ ÀÄÄÙ ÀÄÄÙ ³ ÀÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÙ Switch positions: 1 2 3 4 Switch positions: I/O Address 1 2 (Hexadecimal): OFF OFF 200, 204 ON OFF 300, 304 OFF ON 600, 604 ON ON 700, 704 Set switch positions 1 and 2 to select an I/O address that is not used by any other device in the host PC. To avoid conflicts, remember that the actual I/O address takes up two bytes due to partial decoding. For example, 200-201H and 204-205H for the default setting. Also check the software driver manual. Switch position 3 is covered on the next page. Switch position 4 is not used for setup. Confirm the default OFF position. Figure 3 _ 4-position DIP switch for selecting I/O addresses (Default setting for 200H, 204H shown) NOTE: Programmers who wish to study the definition of the I/O registers, please see Appendix D. SWITCH POSITION 3 _ EXTENDED MEMORY ENABLE When the switch in position 3 is in the: OFF position, you can locate the dual port memory anywhere in the first 16 megabytes of the host PC's memory space. This is the factory-set default position. ON position, you can locate the dual port memory in only the first megabyte of the host PC's memory space. If the host PC has a cache memory, the caching may interfere with the operation of the ACL IIR+. Either: disable the host PC's cache. or place this switch in the ON position to keep the dual port memory in the first megabyte of the address space. Cache memory typically does not act on addresses A0000H through F0000H in the first megabyte. 8-Position Switch _ IRQ Settings The 8-position DIP switch is used to select polled mode operation, or the IRQ that is used in the interrupt mode. Turning OFF all switches selects the polled mode. Turning ON a switch selects the corresponding IRQ. The IRQs available are shown below: ÚÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ¿ ³ ÚÄ¿ ÚÄ¿ ÚÄ¿ ÚÄ¿ ÚÄ¿ ÚÄ¿ ÚÄ¿ ÚÄ¿ ³ ON ³ ³ ³ ³ ³ ³ ³ ³ ³ ³ ³ ³ ³ ³ ³ ³ ³ ³ ³ ÃÄ´ ÃÄ´ ÃÄ´ ÃÄ´ ÃÄ´ ÃÄ´ ÃÄ´ ÃÄ´ ³ ³ ³ ³ ³ ³ ³ ³ ³ ³ ³ ³ ³ ³ ³ ³ ³ ³ ³ OFF ³ ÀÄÙ ÀÄÙ ÀÄÙ ÀÄÙ ÀÄÙ ÀÄÙ ÀÄÙ ÀÄÙ ³ ÀÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÙ 1 2 3 4 5 6 7 8 3 4 5 9 10 11 12 15 Figure 4 _ 8-Position DIP switch settings for selecting IRQ (Default setting of IRQ 5 shown) After making an I/O address and an IRQ (or polled mode) selection, record your choices for future reference in Appendix B. Guidelines for Setting IRQs If the device driver is to be interrupt-driven, make sure that each ACL family board along with every other device installed in the host PC has a unique IRQ, if interrupt-driven. If the device driver supports interrupt sharing among ACL Family boards, all ACL Family boards may be set to use the same IRQ. has only one switch on the 8-Postion Switch in the ON position. NOTE: IRQ 5 is the hardware default because we have found relatively few conflicts with IRQ 5. HOW TO INSTALL THE ADAPTER BOARD The ACL IIR+ adapter board may be installed into any IBM PC/AT computer or any 286, 386 or 486 ISA-bus compatible. Follow this procedure: 1. Place the computer, monitor and all peripheral device POWER switches in the OFF position. 2. Disconnect all power cables from the rear of the computer chassis. 3. Get the guide to operations manual supplied with the computer. Follow the instructions for removing the computer cover and installing a board. 4. The ACL IIR+ board may be installed in any 16-bit full-length expansion slot. After you select a slot, remove and save the retaining screw holding the expansion slot cover plate, and slide out the cover plate. 5. Hold the ACL IIR+ board and carefully align the board's edge connector with the expansion slot connector. Firmly press the board straight down into the expansion slot connector. Make sure that the board is pushed in all the way. 6. Replace the retaining screw and tighten the screw to secure the board. 7. After installing the board, follow the instructions in the guide to operations manual for replacing the computer cover. Then reconnect all power cables. NOTE: To remove the board, follow these steps in reverse. How to Connect Peripherals You can connect up to eight asynchronous serial devices to the RJ-12 ports. Just connect the interface cable of a serial device to any of the ports available on the ACL IIR+ adapter. Make sure the serial cables are no longer than 100 feet, per EIA-232-D. Port numbers and pin-outs are shown below. NOTE: You can plug an RJ-11 connector into the RJ-12 ports. But only pins 2 through 5 will be connected.

The 4-Position DIP switch is used to locate these registers at one of four address locations. The bit definitions for the registers are given below. MAP Register I/O Location Bit Position 7 6 5 4 3 2 1 0 200, 300, 600 or 700 A19 A18 A17 A16 A15 A14 R1 E2 {A19-A16 store the least significant boundary address bits.} For 16K byte dual port boards, bits A14 to A19 are used. For 64K byte dual port boards, only bits A16 to A19 are used, and A14 and A15 should be written as zeros (0) for future compatibility. 1Writing a "1" to the reset bit invokes a hardware reset of the board. This bit should be set to 1 for at least 100 milliseconds to make sure that the processor resets. 2The first 8-bit latch also contains the dual port enable bit. Writing a "1" to the dual port enable bit enables the dual port memory. Megabyte MAP Register I/O Location Bit Position 7 6 5 4 3 2 1 0 204, 304, 604 or 704 0 0 0 0 A23 A22 A21 A20 {A23-A20 store the most significant boundary address bits.} When switch position 3 of the 4-Position Switch is ON, bits A20 to A23 are forced to zero, keeping the dual port address in the first megabyte.
