AXB-PT10/15/30 PosiTrack Camera Controllers
Setting zoom, focus, and iris switches to servomotor or motor mode
Both PosiTrack units support servomotor (+2.5 to +7.5 VDC operating range) and direct-drive
motor (± 6 VDC or ± 12 VDC operating range) lens control. The table below shows how to set the
switches for servomotor mode (S) or motor mode (M). If you are using a direct-drive lens, refer to
the manufacturer's literature to set the VOLT switch for ± 6 or ± 12 VDC control.
Setting the RS-232 DIP switch (S2)
The RS-232 DIP switch (S2) positions 1 and 2 set the stop and data bits, positions 3 through 5 set
the parity, and positions 6 through 8 set the baud rate. FIG. 4 shows the RS-232 DIP switch.
The PosiTrack units contain one EIA RS-232C standard port for equipment that requires RS-232
control. The following communication protocols are supported:
 300, 600, 1200, 2400, 4800, 9600, 19200, and 38400 baud
 7, 8, or 9 Data bits
 1 or 2 Stop bits
 Even, Odd, and None parity settings
