CBLé System Guidebook 21
About Automatic Probe Identification (AutoIDENT)
Automatic Setup Feature
AutoIDENT
enables the CBL to identify the type of
AutoIDENT
probe
connected to a channel and automatically set up the channel with
predefined default values.
Specific resistance values contained in
AutoIDENT
probes are sensed by
the CBL when connected to
CH1
,
CH2
, or
CH3
(analog channels), or to
the ultrasonic channel.
Each of the three TI probes provided with the CBL contain an
AutoIDENT
resistor. When an
AutoIDENT
probe is detected, the CBL sets
the proper operation, loads a conversion equation into memory for the
selected channel, and turns on the Conversion Equation for that channel.
When the Channel Setup command ({1,channel_number,1}) is sent to the
CBL, the channel is ready to collect data immediately.
Note: If an
AutoIDENT
probe is removed after the CBL receives a
Channel Setup command {1,channel_number,1} and a different
AutoIDENT
probe is installed in the same channel, characteristics of the
new probe are not recognized by the CBL.
Therefore, if you change probes, send another
CMD1
({1,channel_number,1}), or send a command to clear the specific
channel ({1,channel_number,0}), a command to clear all channels
({1,0}), or an All Clear command ({0}).
Conversion equations set up by
AutoIDENT
overwrite any equation
previously stored; likewise, a subsequent
CMD4
(Conversion Equation
Setup) will overwrite the
AutoIDENT
values, so you can input your own
parameters if you wish.
The CBL contains provisions for other
AutoIDENT
resistor values. These
values can be used for new probes with the
AutoIDENT
feature. (Refer to
“
AutoIDENT
Probes” in Appendix A.)
