Direction Up - DUP (09.321-C) Value range states {1..180} this is incorrect, as stated in ANSI/NIST-ITL 1-2011
Update: 2015 the value range should be {0..359}
Direction Left - DLF (9.321-D) value also has the same issue, should be {0..359}
Direction Right - DRT (9.321-E) value also has the same issue, should be {0..359}
This stems from Issue #11 where your MRT and documentation are actually based on 2013 spec but should be based on 2015 spec.
