AXB-PT10/30 PosiTrack Camera Controllers
Diagnostic error values
In the Terminal Emulator, of the AxcessX program, you can use the
Device Status
command
to diagnose any problems with the PosiTrack Controller. The following is an example of how to
diagnose problems using the
DEVICE STATUS
and
CLEAR ERRORS
commands to obtain error
values that can help you better track any problems.
1. Turn the PosiTrack Controller On and make sure the proper connections are plugged into the
unit. Open Terminal Emulator in the AxcessX program.
2. Type DEVICE STATUS (device 90) in the Terminal Emulator. The 90 used in this example is
the Device Number assigned to the PosiTrack. The same process can be sent in Axcess using
SEND_COMMAND CAM, <camera #>, "‘GET STATUS’". Refer to the GET ERRORS
Send_Command for more information.
3. Give the Emulator at least 30 seconds to respond with an error value, if any exists.
4. If there is an error present, the emulator displays the number 230 and other values, listed in
the Error Values and Descriptions table on page 40, that correspond to particular problems
encountered during the diagnostic cycle.
5. Type SEND_COMMAND 90, "'CLEAR ERRORS'" to clear the errors in the PosiTrack unit
after the problem is resolved. This command clears all the error messages that may have
appeared while you were diagnosing problems.
6. Turn the PosiTrack Controller Off and fix the problem.
7. Turn the unit On once the problem has been fixed.
8. Repeat steps 3 through 7 until the problem no longer exists.
Positional Commands (Cont.)
PR
Sets the ramp rate of
the specified output
voltage where time is
the time to ramp the full
range both down to up
and
up to down
or
optionally just down to
up
or
up to down
.
This command can be used for servomotor positional mode applications.
Syntax:
"’P<output>R<time>[U|D]’"
Variables (See Parameters - Send_Commands section on page 36):
P - output = 3 - 5
R - time = 0 - 255
U\D = Up or Down
Example:
SEND_COMMAND CAM,"’P3R50’"
Sets zoom ramp rate to 5 seconds full range for “down to up” and “up to down.”
"’P4R75U’"
Sets the Focus ramp rate to 7.5 seconds full range for Down to up. This command
can be used for motor and servomotor positional mode applications.
"’P5R25D’"
Sets the Iris ramp rate to 2.5 seconds full range for up to down only.
When using version 2.04 firmware or higher, the PosiTrack stops all pan and tilt
operations if an internal error is logged. Correct the source of the error and cycle
power on the unit to resume operation. The error channels remain On until a CLEAR
ERRORS or ZAP! command is sent.
