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. 

01 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  [d4]h  LRC1  LRC2  ETX 

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
