2 Purpose

This diagnostic verifies that the SCP's SCIM serial communication path is working correctly.

Short vs. Long Tests: The short test performs a walking ones and walking zeroes pattern whereas the long test will perform a walking ones, walking zeroes, 0xaaaa, 0x5555, and possibly other patterns. As a result, selecting the long test generally provides a longer and more exhaustive test. If the problem is highly intermittent then you may want to run a long test.

3 Components Tested

The SCP is the only component tested. The PSE and SCIM are not tested.

4 Requirements

None

5 Test Sequence

  1. The SCP transmits a data packet through the SCIM serial port on the SCP board.

  2. The serial data is internally looped back into the SCIM serial port.

  3. The SCP verifies that it received the same data that was sent.

note:

Do not change the Test Options settings from the default settings unless instructed to do so by a GE Healthcare engineer. There are very few circumstances when these settings need to be changed.

6 Expected Results

Output values pass or fail. In the event of failure, the details of the failure can be found in the GE System Log.

If this test fails, it is possible that the SCP board is defective.

Although, in the case of errors you can click the 1st Error number to see the nature of the error, it is recommended that you view the GE System Log to view all the errors that were recorded.
