The following is a description of the Parameter Send-Host Transmission Characters.
Character 1 - STX:
This is the first character in the character string. None of the other characters will
be recognized without this character prefix. Always use the ASCII “STX” character
to enable the M–Traverse's receive buffer.
Characters 2, 3 - Device Number:
These characters are the access address of the M–Traverse. This number
identifies individual M–Traverses on a multidrop system. The M–Traverse will
accept data only if this number matches the M–Traverse's address (CP-70), with
the exception of a “00” address. The “00” address is universally accepted by all
M–Traverses that are on the RS422 Serial Communications Interface.
Character 4 - Message Type:
This character should always be “3”.
