Teledyne API' implementation of Hessen protocols includes a set of status bits that are
included in responses to inform the host computer of the T200H/M's condition. The
default settings for these bit/flags are:

Table 4-37: Default Hessen Status Bit Assignments

STATUS FLAG NAME
It is possible to assign more than one flag to the same Hessen status bit. This
allows the grouping of similar flags, such as all temperature warnings, under the
same status bit. Be careful not to assign conflicting flags to the same bit as each
status bit will be triggered if any of the assigned flags is active.
