Help with "Break Command"

I am trying to control a 360 Systems Digicart E using an NI-700 over RS-422. I've had very little success and after a lot of time on the phone with 360, they're convinced that I may be sending the wrong kind of break command before each play command. I have been using the code taken directly from the AMX website which shows the break command as:
(*** Send Break character ***)
SEND_STRING DEV,"27,17,10"
The Digicart E manual describes the break command as follows: "The Break character is defined as a minimum of 20 bits Space followed by a minimum 2 bits Mark. It is used to synchronize all devices connected to the interface bus."
Can anybody out there tell me if they see what I am doing wrong? Is this break command actually the source of my problem or is this correct and I can start looking elsewhere for the issue? Anything would help.
Thanks,
Mike

I've uses this on a DataVideo switcher. The $30 may be those min 2 bits the device is looking for.
The 60 is the duration of the break (6 msec). $30 is ASCII for 0.
