Page 7: Chapter 1 - Introduction
Except for the computer bus interface and an additional step in the hardware configuration process, MEGAPLEX/2 and MEGAPLEX/RS products are identical to their MEGAPLEX counterparts. Throughout this manual, the term MEGAPLEX refers to all products. MEGAPLEX boards provide: High Performance. All 96 ports are capable of running 38.4 Kbps on all ports simultaneously. -

MEGAPLEX CMX-24D Cluster Multiplexer (& accessories) About This Manual This manual is a technical reference to the hardware installation and operation of the MEGAPLEX family. It should be used in conjunction with one of the MEGAPORT/MEGAPLEX device drivers discussed below. -
Page 9: Equipment Check List
Equipment Check List A MEGAPLEX 24-Port Kit contains a host controller board, one or more cluster multiplexers and all applicable accessories (hardware, software and documentation) required by the user's system. MEGAPLEX MCC 24x4 Host Controller Board Installs in an 80386- or 80486-based computer. - Page 10 Different device driver kits with different part numbers are provided with MEGAPLEX, MEGAPLEX/2 and MEGAPLEX/RS (slight differences in the installation process necessitate this for ease of installation). With MEGAPLEX/2 host controller boards a PS/2 Option Diskette is also included. MEGAPLEX Hardware Reference Manual...

Page 11: Software Support
Software Support MEGAPLEX products are supported under various operating systems by different software device drivers supplied by Equinox and other vendors. The following device driver kits (including diskettes and manuals) are available for both MEGAPORT and MEGAPLEX: UNIX System V 3.2/386 operating system, SCO XENIX 286 or 386 operating system and compatible variants. - Page 12 MEGAPLEX Hardware Reference Manual...

Page 13: Chapter 2 - Installing Megaplex Hardware
EISA Installations When installing a MEGAPLEX board in an EISA system, a jumper must be installed to permit the configuration scheme to work properly. Install the jumper across the two pins designated PA0 on the top of the board as shown in Figure 2-1. -
Page 14: Installing A Single Megaplex Board
Installing a Single MEGAPLEX Board The MEGAPLEX host controller board should be installed in the first available computer slot. On a desktop type chassis, this is the first empty slot closest to the power supply. The first empty slot closest to the power supply facilitates installing additional boards using the 1- inch interconnect cable. - Page 15 Tighten the screw firmly so that it holds the board in place. 7. If more than one MEGAPLEX host controller board is to be installed, proceed to the paragraph heading Installing Additional MEGAPLEX Boards.

Page 16: Installing Additional Megaplex Boards
Installing Additional MEGAPLEX Boards Additional MEGAPLEX host controller boards may be installed in a computer. And, MEGAPLEX subsystems may be freely intermixed with Equinox MEGAPORT products. (MEGAPLEX/2 subsystems may be freely intermixed with MEGAPORT/2 and MEGAPLEX/RS subsystems may be freely intermixed with MEGAPORT/RS.) - Page 17 J3 connector on the previously installed board located to right of the new board. 6. If more than one additional MEGAPLEX board is being installed, repeat steps 1 through 5 for each board. Note: If the computer has trouble finding the second MEGAPLEX board, suspect a faulty connection with the 1"...

After installing the MEGAPLEX/2 host controller board, the computer must be configured. The first time the machine is turned on with the MEGAPLEX/2 installed, an error code of 165 appears and 2 beeps are sounded after the RAM is counted. This error message indicates that the configuration has been changed and the machine must be reconfigured to recognize the MEGAPLEX/2. - Page 19 4. Set features. 5. Copy an option diskette. 6. Test the computer. Because the MEGAPLEX/2 installation modifies the Refer- ence Diskette, a backup of the diskette should be made. A blank 1.44 MB diskette that is not write protected is re- quired.

5. After running the automatic configuration the system CMOS contains the configuration of all adapters including the MEGAPLEX/2. At this point, backup the new configura- tion by selecting option 3, Backup configuration, from the set configuration menu. 6. The new configuration is copied onto the Backup Reference Diskette. -
