Ortho-Axis Positioner – Pneumatic (Optional)
A 12-volt DC wall-mounted power supply provides the DC power to the control
unit. It connects to the control unit through a two-pin receptacle on the side of the
enclosure. A serial cable connects the control unit to the serial port in the
computer. A nine-pin D-sub connector is mounted on the side of the control unit
for this connection.
Place the positioner in the GTEM! so that the recess in the base plate fits over
the center strip in the GTEM!. The mounting plate will be positioned in one of the
three orthogonal positions within the GTEM! at each of the fixed positions.
The Ortho-Axis Positioner can be controlled through Hyperterminal or other
control software. If using Hyperterminal, the settings must be as follows:
Baud: 9600
Data Bits: 8
Parity: None
Stopbits: 1
Flow Control: None
The commands to control the positioner are:
Bit 01 Bit 02
Position 1 $CB01 $CB02
Position 2 $SB01 $CB02
or $CB01 $SB02
Position 3 $SB01 $SB02
# - Transmitted on startup
$ - Used to denote commands
* - The response for valid commands
ER – The response for invalid commands
SBxx = Sets corresponding Bit high – for example, $SB01
CBxx = Clear corresponding Bit – for example, $CB01
RBxx = Read corresponding Bit – for example, $RB01
*1 if Bit is set
*0 if Bit is clear
RR = Resets the control unit – for example, $RR
