Section F
There are three different tests:
(1)
Constant speed test.
By pressing keys mA+ and mA- on the keyboard, the step
motor is supplied so as to have a constant speed.
By releasing the key, the movement stops.
(2)
Variable speed test.
By pressing keys kV+ and kV- on the keyboard, the step
motor is supplied with a variable speed, starting from the
lowest and reaching the highest. When the key is released,
the speed decreases from the speed reached to zero.

Modify the movement start position.
With this procedure you can modify the start position of the
movement via software, instead of by changing the actuator
of the relevant optoswitch.
Pressing keys s+ and s- will change the number indicating
the start position (default = 0).
The correspondence between the number displayed and
the shift in mm is the following:
mm = 0.0728 X n displayed
This procedure is useful when you have to change the start
position of the C movement after having checked the systemw i t h
the image quality phantom (see the paragraph "Verify
centering of the system with the image quality phantom" in this
section).
(2)
For Orthoralix 9200 DDE Ceph versions:
By selecting this service program you can check the functioning of
the ceph movement (step motor, wiring and power supply from the
host computer board PC1) and change the relevant start position
of the ceph scanning cycle.
The following message will appear on the display:
-C- TEST & ADJ.
+0 +0 XYRABC
where:
-
the first number indicates the actual position of the
movement with respect to the reset position
-
the second number the correction introduced to modify the
start position of the movement
-
XYRABC the status of the optoswitches related to the
movements :
. X = start position of the X movement
. Y = start position of the Y movement
. RAB = start position of the rotation movement (2
optoswitches)
. C = start position of the cassette movement
If a capital letter is visualized (XYRABC) the related optoswitch
has been activated; if a small letter is visualized, the related
optoswitch has not been activated.
There are three different tests:
(1)
Constant speed test.
By pressing keys mA+ and mA- on the keyboard, the step
motor is supplied so as to have a constant speed.
By releasing the key, the movement stops.

4.3.5. IP address
the
This service program is applicable only for the Orthoralix 9200 DDE
versions.
By selecting this service program it is possible to check and to
change the IP (Internet Protocol) address of the Orthoralix 9200
DDE when it is connected to the LAN network. The IP address is
made of four numbers, having a range from 0 to 255. A default
address is stored: it is possible to modify it by:
1)
pressing keys kV + and kV - for the first number on the left
2)
pressing keys mA + and mA - for the second number on the
left
3)
pressing keys s + and s - for the third number on the left
4)
pressing keys progam + and program - for the last number
The following message will appear on the display:
Please take note that the address appears on the display only
when the connection to the LAN network is done properly: it takes
approximately 30 s from the system switching on. So, if this service
program is selected during this time, the address displayed is: 0,0,0,0.
After the modification of the IP address, to store it in the system,
press Dummy Run: for a while on the display will appear 0,0,0,0
and then the new IP address.
