Message packet canceled [E_CANCELED_I]
Comment: The message packet was canceled before the response was received. This is
not an error but merely records the current state of a message packet. The
driver normally cancels all outstanding message packets when it goes off
line.
Action: None.
Message packet not sent yet to the C/C [E_WAITING_I]
Comment: Indicates that the message has been queued up in the MAPI's buffers for
transmission but has not yet been sent. Reported as the Carm device status
if the fast query message was not sent before the beginning of the next A/C
line cycle.
Action: Because the driver must communicate with the C-arm every A/C line cycle,
and because all other devices share the communications link, any device that
causes an I/O error (e.g., a timeout) generally causes this error in the C-arm.
The first thing to do is to determine if the problem is really with the C-arm
or with another device in the system. Place all devices in emulation mode
(e.g., by turning off instrument power and booting up in the workstation
mode). Then, first take the C-arm out of emulation. If it reports no errors,
then proceed to take each one of the other devices out of emulation mode
until the one in error is found. Also see the discussion under "BAD
CHECKSUM IN MESSAGE." for diagnosing I/O errors.
Message packet sent and waiting for response [E_SENT_I]
Comment: The message has been sent but the response has not yet been received.
Reported as the C-arm device status if the fast query response for a cycle is
not received before the next cycle.
Action: See the discussion of the associated error E_WAITING_I.
Missing ARRC.TXT file.
Action: Check that ARRC.TXT exists in C:\XCDATA. If it does, re-boot to ensure
that the system is correctly initialized. If not, restore ARRC.TXT from a
dbarchive backup.
Missing tissue bar initialization file
Software Error: The file that contains the calibration information for the tissue bar is missing
or has not been installed.
Action: Install the tissue bar initialization software that comes with the tissue bar.
