The following is a description of the Control Command Send - Host Transmission.

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 “1”.
