MODELS 483C30, 483C50, 482M179 AND 483M217 GENERAL OPERATION MANUAL
2-9.
Non-Volatile Memory
This feature provides a mechanism to save and restore a programmed configuration. The programmable settings are
saved when the unit receives a SAVS command and restored when the unit powers up. The unit's non-volatile memory
may be reset to the factory default settings by using the RSET Command.
2-10. Transducer Electronic Data Sheet (TEDS) Interface:
TEDS sensors attach to the input connectors the same way a traditional ICP® sensor is attached to the signal
conditioner. The TEDS interface requires the Ethernet computer interface, and the input mode option. The digital
control and input mode features automatically perform the TEDS read or write function. After the communication with
the TEDS sensor is complete the input mode returns to the input mode (charge or ICP®) prior to the communication.
The current TEDS function will perform a read of the "raw" TEDS data and return the 32 bytes of TEDS sensor
EEPROM data and the 8 byte Application register contents, if it was programmed, and returns the data in an ASCII Hex
representation.
2-11. Filtering
Most Model 482C's can be ordered with optional Input and/or Output Filters which may be enabled and disabled for
each individual channel. The standard options are described below.
2-11.1 Output Filtering
The Model 482C can be ordered with low pass or high pass Output Filters installed in any or all channels for the
removal of unwanted noise. Output filters are located at the end of the signal path, after any gain has been applied. The
available Output Filter modules are fourth-order Butterworth low pass (-24 dB/octave) filters. High pass filters are
available upon request. The Output Filters are factory-installable only. Typical cutoff frequencies include:
The user may also define a specific cutoff frequency for the Output Filters that satisfies a specific need. Contact the
factory regarding individual requirements and model ordering code.
