H.4 If the MRU Has a One-Way Serial Connection

There may be instances where the serial connection from the MRU to Isis is one-way. This is
necessary when a single MRU is talking to several computers simultaneously. In this case,
Isis cannot transmit a “Get Digital Output Format” command to the MRU. When that happens,
Isis cannot automatically configure to the data format of the MRU.

Under this condition, Isis assumes a default configuration for the MRU. This default is most
commonly used for collecting attitude data in conjunction with bathymetric data processing.
The MRU is assumed to be transmitting only the data shown in Table H-2.
