A-6 PTX-PRO Specifications
PTX-PRO User and Technical Manual
To access both radio and Wayside data, connect the DB-9 female
RS-232
connector of the
Multipurpose Data Cable (shown) to the PTX-PRO
RS-232
connector.
The Multipurpose Data Cable contains two DB-9 female connectors and one DB-9 male
connector and contains band markers indicating connections to
HOST
,
WAYSIDE
, and
RS-232
connectors.
•
The
HOST
DB-9 male connector is a Data Terminal Equipment (DTE) device that
connects to a PC. When you connect the Multipurpose Data Cable to a
HOST
DB-9 male
DTE device, you also must connect a null modem between the DTE device and the
HOST
male connector. If the
HOST
connector is connected to a DCE device, you cannot
use a null modem cable, but you will need a straight pin-to-pin extension cable.
•
The
WAYSIDE
DB-9 female connector is a Data Communication Equipment (DCE)
device connector that connects to a modem, GPS, etc. When you connect the
Multipurpose Data Cable to a
WAYSIDE
DB-9 female DCE device, you also must
connect a null modem between the DCE device and the
WAYSIDE
female connector. If
the
WAYSIDE
connector is connected to a DTE device, you cannot use a null modem
cable, but you will need a straight pin-to-pin extension cable.
The following table shows programming connections using the Multipurpose Data Cable.
