RTED
The RTED query returns the TEDS information that is stored in the sensor or other, TEDS capable, in-line
module attached to a specific channel. The signal conditioners are IEEE 1451.4 compliant in that they will read
the family code of the 1-wire memory chip to determine its type. If a DS2430A is found, its Application
Register status will be read to see if the 64 bit Application Register has data in it. If so it will read the
Application register contents and return it followed by the contents of the TEDS EEPROM.
NOTE: The 1
st
byte of the DS2430A EEPROM data should contain the checksum of both the Application
Register contents and the EEPROM contents if the TEDS is IEEE 1451.4 compliant. No attempt is made to
validate or interpret the TEDS data.
Setting:
N/A – Command is Read only
Query:
The RTED query returns the TEDS data associated with the specified channel. This command must be directed
to a specific channel. It will return an indicator that specifies the family code of the 1-wire memory chip that
was read or, if the chip was a DS2430A, it specifies that the status of the Application register; 1 if it contains
the basic TEDS data or 0 if not. This byte is followed by up to 40 bytes in ASCII Hex format (8 bytes of
Application register content if it was used and 32 bytes of the EEPROM content).
Query Format: Unit#:Ch#:CMD?
Response format: Unit#:Cmd:Ch#= <APP Reg Status>:<APP Reg Contents (8 bytes if APP Reg
Status=1)><DS2430A EEPROM Contents (32 bytes)>
Where: APP Register Status = 1 if the APP Register is locked (has data) or 0 if it did not and
the chip is a DS2430A. Otherwise it will return the Family Code of the chip that was detected
(45=DS2431; 35=DS2433 or 67=DS28EC20)
Query: 1:1:RTED?
Response: (for TEDS chip on channel 1 with valid app register data)
1:RTED:1=1:168010a00975000012648016a88ae8e112801f2000f60ec4046dd18737f3206a380555e7

ALLC
The ALLC command is used to read several channel settings at once.
Setting:
N/A – Command is Read only
Query:
This command must be a directed command use of the global channel indicator is not allowed.
Query Format: Unit#:Ch#:CMD?
Response format: Unit#:Cmd:Ch#:= GAIN:<Gain value>; SENS:< SENS value>; FSCI:< FSCI
value>; FSCO:< FSCO value>; INPT:< INPT value>; FLTR:< FLTR value>; IEXC:< IEXC value>;
