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 MLP–Trim's receive buffer.

Characters 2, 3 - Device #:

These characters are the access address of the MLP–Trim. This number identifies

individual MLP–Trims on a multidrop system. The MLP–Trim will accept data only if

this number matches the MLP–Trim's address (CP-70), with the exception of a “00”

address. The “00” address is universally accepted by all of the MLP–Trims that are

on the RS485 Serial Communications Interface.

Character 4 - Message Type:

This character should always be “3”.
