1. 35h (ASCII hex) = 5H = 00000101
42h (ASCII hex) = Bh = 00001011
Note: 03h is the EXT character (end of transmission) and is
not part of the message.
2. 00000101 = 01010000
3. 01010000 + 00001011 = 01011011
4. 02h + 42h + 31h + 30h = A5h
5. A5h + 5Bh = 100h
6. The least significant byte is zero so the message and
LRC match.
Response or status bytes are sent from the TMS7 as an ASCII
string.
STX [d1]h [d2]h [d3]h
d1 = 30h
d2 = 30h
d3 = 30h plus upper nibble of status byte right shifted by four
binary places.
d4 = 30h plus lower nibble of status byte.
For example status byte = 1Fh, response is
STX 30h 30h 31h

Status.7 50 Hz Only one of either Status.7 or
Status.6 can be at logic 1 when the
TMS7 is operating.
Status.6 60 Hz

Status.3 Positive Will be at logic 0 when there is a
phase negative phase rotation.
