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;
it enables the ML-Drive's receive buffer.
Characters 2, 3 - Device #:
These characters are the access address of the ML-Drive. This number identifies
individual ML-Drives on a mutltidrop system. The ML-Drive will accept data only if
this number matches the ML-Drive's address (CP-70), with the exception of a “00”
address. The “00” address is universally accepted by all of the ML-Drives that are
on the RS485 Serial Communications Interface.
