Setting
:
1:0:SWOT= 4\r\n
( unit 1, channel NA, Channel 4 is switched to the switched output BNC )
Setting Response: 1: SWOT:ok
Query
:
The SWOT query returns all channels coupling setting.
Query Format: Unit#:Ch#:CMD?
Response format: Unit#:Cmd:Ch#:= <channel # or 0=OFF>;
Query: 1:1:SWOT?
Response: 1:SWOT:1=4;
CALB
The Calibration mode (CALB) command selects the calibration setting. For the 482C27 the options are OFF, Internal
Shunt + or Internal Shunt -. For other models External Cal and Internal Cal using internally generated 100Hz or 1kHz
sine wave signals are available.
The CALB value is sent as an integer value of either 0 –Disable, 1-1000 Hz Enable, 2-100 Hz Enable, 3-
External Cal, 4 -Internal Shunt +, 5 – Internal Shunt -
Setting
:
1:1: CALB= 4\r\n
( unit 1, channel 1, Internal Shunt Cal + )
Setting Response: 1:CALB:ok
Query
:
The CALB query returns the channels calibration setting.
Query Format: Unit#:Ch#:CMD?
Response format: Unit#:Cmd:Ch#:= <0|1>;
Query: 1:1: CALB?
Response: 1: CALB:1=4;
Global Query: 1:0:CALB?
Global Response: 1:CALB:1=4;2=0;3=0;4=0;
RTED
The Read TEDS (RTED) command returns the TEDS information that is stored in the sensor or other, TEDS capable,
in-line module attached to a selected channel. The 482x devices are 1451.4 compliant in that they will read the
DS2430A Application Register Status to see if it indicates 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 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 if the DS2430A Application register has been
