System Channels; Digital Input Channels - HBM SomatXR CX23-R User Manual

CX23-R and EX23-R
Note that this "PPS sync" can only be achieved when the GPS module is providing
fix date and time information. This will not be immediately available when the GPS
module is first connected to the SomatXR/eDAQXR system, or after the
SomatXR/eDAQXR is power cycled, or if the vehicle loses GPS satellite reception
for any other reason. The time required for the "PPS sync" to become active is in part
module type dependent, but can vary from a few seconds to well over one minute.
The system provides a "pps_sync_active" channel; this is a logical channel that is
true (1) when the "PPS sync" is active and false (0) when it is not active.
The SomatXR/eDAQXR supports a GPS raw message channel that captures all of
the NMEA sentences received from the GPS module. The timestamps for the
messages are the times when the messages were received – not the "PPS sync"
adjusted times.
Expiration time: Specify the time period in seconds that can elapse without data
before data is considered stale and the output is set to the invalid value. The value
may be any real number greater than zero.
Invalid value: Specify the value to be set when the expiration time has elapsed
without any data. The value may be any real number.
4.3.6 System channels
System channels are sourced from the data processor unit.
4.3.7 Digital input channels
Digital inputs are sourced from a CX23-R DIO connector.
Threshold mode: Only the Static mode is available.
Low threshold (mV): Specify the low threshold value (as an integer not less than
-5000). If the low threshold value changes, all channels on the same signal input
line are changed to the same value automatically.
High threshold (mV): Specify the high threshold as an integer not greater than
5000 and greater than the low threshold by at least 20. If the high threshold value
changes, all channels on the same signal input line are changed to the same value
automatically.
Transducer power: Set the transducer power mode to Off, 5 V or 12 V. If the
transducer power is changed, all digital input and output channels are changed to
the same mode automatically.
MX temperature channels
Temperature channels are sourced from a
