6.10.4 Multipurpose Data Cable
In order to access both radio and Wayside data, you need to use
a Multipurpose Data Cable. The cable and wiring diagram are
shown in Figure 6-17 on page 6-16. If necessary, the
Multipurpose Data Cable may be ordered from MRC.
The Multipurpose Data Cable contains two DB-9 female
connectors and one DB-9 male connector. The Multipurpose
Data Cable contains band markers indicating connections to
HOST, WAYSIDE, and RS-232 connectors. The Multipurpose
Data Cable DB-9 female RS-232 connector is connected to the
PTX-PRO RS 232 connector.
The HOST DB-9 male connector is configured as a Data
Terminal Equipment (DTE) device connector for connection to a
PC or laptop PC. When connected to a DTE device, a null
modem cable must be connected between the DTE device and
the Multipurpose Data Cable DB-9 HOST male connector. If
connected to a Data Communications Equipment (DCE) device,
a null modem cable cannot be used, but a straight pin-to-pin
extension cable will be required.
The WAYSIDE DB-9 female connector is configured as a DCE
device connector for connection to a modem, GPS, etc. When
