N/A – Command is Read only
Query
:
This command is a global command and will return all channel bias readings regardless of the channel id in the
command.
Query Format: Unit#:Ch#:STUS?
Response format: Unit#:Cmd:Ch#:<unit status bit map>;<CH1 status bit map>;…;<CHn status bit
map>;
Query: 1:1:STUS?
Query Response: 1:STUS:1:0;1;5;5;5;
Where :
Unit Bit 0 = 1= BAD EEPROM read for channel settings on power up
Unit Bit 1 = 1= BAD EEPROM read for Unit options on power up
Unit Bit 2 = 1= BAD EEPROM read for cal factors on power up
For Unit bit map 0=no errors
Channel Bit 0= Short input fault (0=Fault; 1 = no fault)
Channel Bit 1= Open input fault (0=Fault; 1 = no fault)
Channel Bit 2= Overload condition (0=Overload; 1 = no Overload)
For channel bit map 7=no errors
UNIT
