Installing The Round Cable - Equinox Systems MEGAPORT Hardware Reference Manual

Installing the Round Cable

Each MEGAPORT package includes a round cable which plugs into
the 100-pin female connector on the MEGAPORT board.
MEGAPORT 12-port boards use a single round cable providing one
standard telco 50-pin telco connector. MEGAPORT 24-port boards
use a double round cable providing two telco connectors.
Equinox wiring accessories convert the telco connectors to DB-25 or
RJ-11 modular jacks for distribution of ports to external devices such
as terminals, modems and printers. The pinouts of the telco
connector vary based on whether the board is a CS, FM or LD type.
Telco pinouts and wiring diagrams for the various CS and LD type
accessories are found in Chapters 3 and 4, Connecting Devices To CS
& FM Ports and Connecting Devices To LD Ports, respectively.
NOTE: The FM board connector pinouts are proprietary to
Equinox and are not furnished. However, the RS-232 signals
for the RJ-45 (10-pin) modular splitter (device connection)
pinouts are identified in Chapter 3.
Follow these steps to connect the cable to the MEGAPORT board:
Locate the 100-pin female connector on the back of the
MEGAPORT board.
Notice that the 100-pin cable connector is keyed such that it
can only attach to the board in one orientation. With the
cable properly oriented, insert the 100-pin male cable
connector into the female MEGAPORT board connector and
press firmly. Tighten the screws to hold the cable securely
to the board.
Equinox 25-pair extension cables may be used to extend the distance
from the cable attached to the MEGAPORT board to the cabling
accessories. These cables plug into distribution panels, punch blocks,
fan-out cables and modular splitters. Extension cables in various
lengths are available from Equinox.
