Installation

AXB-PT10/15/30 PosiTrack Camera Controllers

Using the AXlink connector with an external RS-232 control device or PC (Stand-

Alone only)

To use the AXlink 4-pin connector with a PC or other RS-232 controller, wire the AXlink

connector to a DB-9 female connector, as shown in FIG. 23. Connector pins 2, 3, and 5 are used for

data and ground. For some applications requiring hardware handshaking, it may be necessary to

strap pins 7 (request to send) and 8 (clear to send) together.

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 PT10, PT15

and PT30. 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 9 for more information.
