Command Description
CF1xxxx Automatic Ensemble Cycling – Automatically starts the next data collection cycle after
the current cycle is completed. Only a <BREAK> can stop this cycling.
CF0xxxx Manual Ensemble Cycling – Enters the STANDBY mode after transmission of the data
ensemble, displays the “>” prompt and waits for a new command.
CFx1xxx Automatic Ping Cycling – Pings immediately when ready.
CFx0xxx Manual Ping Cycling – Sends a < character to signal ready to ping, and then waits to
receive an <Enter> before pinging. The <Enter> sent to the Channel Master is not ech-
oed. This feature lets you manually control ping timing within the ensemble.
CFxx1xx Binary Data Output – Sends the ensemble in binary format, if serial output is enabled
(see below).
CFxx0xx Hex-ASCII Data Output – Sends the ensemble in readable hexadecimal-ASCII format, if
serial output is enabled (see below).
CFxxx1x Enable Serial Output – Sends the data ensemble out the RS-232/422 serial interface.
CFxxx0x Disable Serial Output – No ensemble data are sent out the RS-232/422 interface.
CFxxxx1 Enable Loop Recorder – Records data ensembles on the Loop Recorder.
CFxxxx0 Disable Loop Recorder – No data ensembles are recorded on the Loop Recorder.
Example CF01010 selects manual ensemble cycling, automatic ping cycling, Hex-ASCII data
output, enables serial output, and disables data recording.
