Communications Formats

Of the nine RS-232 formats used with the N-200, six produce
ASCII trend and event data output (Full, Conditional Full,
Computer, Alternate Computer, Conversation, and Beat-to-
Beat). Conversation format is recommended for accessing trend
and event data.
WARNING: In Full, Computer, or Beat-to-Beat Formats,
real-time data output is inhibited while the trend and
event data are being transferred to the ASCII device.
The current monitored data for this period is not
available.
