Table 1-8 lists the senTorr serial commands. All lower case characters must be replaced as
follows:
aa unique 2 digit hexadecimal bus address (""00" ...:99"), as set on the
unit
hh 2 character hex data value (00 ...FF")
c 1 character channel type ("1", 'or") where I = BNCC
T=TC
n 1 character channel number where IG = 1, TC1 = 1, TC2 = 2 x = 1
character data value ("1" '19")
