CS Port Signals
Signal Names
The names of signals on the telco connectors of the MEGAPORT
ports indicate the direction of the signals. They are either inbound
(received by MEGAPORT) or outbound (transmitted from MEGA-
PORT).
Data Signals
The following names are used for data signals:
DATA IN indicates data received by the MEGAPORT board
from the attached device (inbound).
DATA OUT indicates data transmitted from the MEGA-
PORT board to the attached device (outbound).
EIA Control Signals
The following names are used for modem control signals:
CNTL IN indicates the control signal received by the
MEGAPORT board (inbound).
CNTL OUT indicates the control signal transmitted from
the MEGAPORT board (outbound).
The conversion to RS-232 from the MEGAPORT telco pinouts and
signal names (DATA IN, DATA OUT, CNTL IN and CNTL OUT) is
accomplished by using Equinox modular adaptors and/or RS-232
distribution panels. The information below should assist in selecting
the correct modular adaptor for the particular application.
Conversion to RS-232 Signal Names
The conversion to RS-232 from the CS telco connector pinouts and
MEGAPORT signal names (DATA IN, DATA OUT, CNTL IN, and
CNTL OUT) is accomplished with one of the Equinox cabling
accessories.
These accessories and wiring techniques are discussed under the
paragraph heading Wiring to Terminal Devices.
