10 Equinox MEGAPORT Hardware Reference Manual

EISA Installations

When installing a MEGAPORT board in an EISA system, a jumper

must be installed to permit the configuration scheme to work prop-

erly. This jumper causes the MEGAPORT board to occupy I/O ad-

dresses 0x340 and 0x341. These addresses should not be used by

another device.

Install the jumper across the left top-most two pins denoted by "PA0"

on the printed circuit board (see Figure 2-2). This figure shows only

PA0 installed to select addresses 0x340 and 0x341. Install the jumper

in the same location on all MEGAPORT boards.

Intermixing MEGAPLEX & MEGAPORT

MEGAPORT boards may be intermixed with other Equinox products

including the MEGAPORT 8CS and MEGAPLEX. MEGAPORT/2

boards may be intermixed with MEGAPLEX/2. MEGAPORT/RS

boards may be intermixed with MEGAPLEX/RS.

The MEGAPORT 8CS is in all respects equivalent to a 24CS board

except it has RJ-11 modular jacks on the mounting bracket. It

installs in a system the same as a MEGAPORT board except for

device wiring. Refer to the MEGAPORT 8CS Hardware Reference

Manual (part number 560044) for more information.

The MEGAPLEX serial I/O subsystem is functionally equivalent to

multiple MEGAPORT boards and may also be intermixed in a com-

puter. There are some minor considerations in the physical installa-

tion. Refer to the MEGAPLEX Hardware Reference Manual (part

number 560050) for more information.
