Error Message List
Address in the response message did not match the address in the sent
message. [E_ADDRESS_MISMATCH_I]
Action: This message should be reported to Hologic Technical Support. Include as
much information as possible about the scan.
Analysis aborted. d0= ___ below acceptable limit.
Hardware or
Softwar Error:
d0 is found to be below zero, which is not possible if there are X-rays reaching the
detector.
Action: This message should be reported to Hologic Technical Support. Include as
much information as possible about the scan.
Arm and table are in danger of colliding! [E_COLLISION_IMMINENT_I]
Comment: The C/C has calculated that the C-arm and table are within 1/4".
Action: If the C-arm and table are really within this distance, the problem is with the
application (or operator) that moved them so close. If they are not, then
either the calibration information for the system is wrong or the mechanical
stops for the table and C-arm have moved. One or more of the motors may
have stopped short of the actual mechanical stop during calibration. Verify
that the positive limit positions for each motor correspond to the published
specs for the model. To recover from this, select the
Utility
option from the
main menu and then select the
emergency Motion
option from the sub-
menu. By holding down the
Enable
button on the operator control panel,
you can use the keypad to move the table and C-arm away from each other.
Bad checksum in message. [E_BAD_BLOCK_I]
Comment: The checksum calculated by the C/C for a message did not match the one in
the message packet.
Action: Either the driver is incorrectly configured, one or more devices are
jumpered to the debug mode, there is a hardware problem on the
communication link (cable or connectors) or one of more of the DSP chips
in the C/C or DAS board is not properly seated. Verify that the
DEVICE=C:\MENU\MAPIDEV.SYS line in CONFIG.SYS has the options
/OVERLAP=0 and /HANDSHAKE=1. Check each stepper motor board and
verify that its address is correctly set. Verify that the TZ motor board
does
not
have the debug jumper installed. Verify that the communications cable
is installed and properly secured on the back of the C/C board. If the
problem persists, it may be because one (or both) of the DSP chips on the
