AXB-PT15 PosiTrack Camera Controller
Using the RS-232 DB-9 connector
The RS-232 DB-9 (male) connector on the PosiTrack units connect to the camera head’s RS-232
connector. The following table shows the (DB-9) RS-232 connector wiring diagram.
Preparing the PosiTrack Controllers for communication
The AXlink Device DIP switch is located beneath the round cover on the back of the PT15.
Set these switches to the desired device value based on the number of PosiTrack units being used in
a particular system. The initial unit is defaulted with a device number of #90. Any additional units
must have values that do not conflict with other PosiTrack units being used. Refer to the Setting the
AXlink Device DIP switch (S5) section on page 8 for more information.
