Data Cable Wiring
C.1
Wiring TracVision SA to a
15-pin Data Connector
In some instances, the IRD provided with a satellite TV service
may be equipped with a 15-pin connector (DB15 wide-band data
port), rather than a 9-pin connector (DB9 low-speed data port).
There are two methods that will allow a TracVision SA system to
function through a DB15 port.
Splicing a DB15 Connector to the Data Cable
It is possible to splice a DB15 connector to the TracVision SA data
cable after removing the male DB9 connector. The alternate
wiring arrangement is as follows:
DB9 Pin
Wire Color
Function
DB15 Pin
2
Blue/White
TXD
14
3
White/Blue
RXD
6
5
Green/White
GND

Creating a DB9-to-DB15 Adapter
It is also possible to construct a DB9-to-DB15 adapter that will
remove the need to cut and splice the data cable. When
constructing such an adapter, follow the DB9-to-DB15 pin
arrangement detailed in Table C-1.
