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.

For RS232 stand-alone mode, the 8-position AXlink Device DIP switch (S5) positions
1 thru 8 must all be set to Off (all down) and the internal communication jumpers must
be set to RS232 mode. For more information, refer to the Jumper Settings (top
view) table on page 12.

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.
