The XML specifies what sensor id is assigned by the DSM to each sample received on a serial port. It is likely that the mapping of I believe the XML was checked at that time, and it contained the intended mapping from serial port to sensor id in the XML was correct, matching the intended configuration. Assuming so, it then seems . So at that time it appeared that the actual relation between sensor id and location on the wide array was as follows:
...
If the above relation of sensor id to location is was true, then our data processing, which used the intended configuration, assigned wrong location suffixes to the data from those sonics for the wide array.
...
First, the serial number to sensor id relation can be read from the data archive, since the rserial output is archived. Assuming Tom progressed through the serial ports in order, they show the serial number sequence to be 744, 745, 376, and not 745, 376, 744. The sensor ids are also in time order, : 2040, 2050, 2060, and the mapping of sensor id to serial number matches the intended configuration, and not the crossed configuration:

Perhaps two mistakes were made which cancelled each other: cross-cabling, and making the wrong association between serial port and sensor id in the XML? Or perhaps the XML on the DSM was corrected to match the cabling shortly after the wide array started, and then corrected back for array2? Both seem unlikely. The sequence of the above serial numbers suggest that neither of the above occurred, and that the serial ports were recorded incorrectly in Tom's log message.
I (Gordon) also do not believe that the sensor ids were altered in the archive after it was recorded.
