READ:SYS:CAT?
A system with no daughter boards would return the following:
STAT:DEV:MB0 :TEMP:DEV:MB1 :HTR
This message indicates the motherboard has one temperature sensor in id0 and one
heater in id1.
A system with one set of daughter boards might return the following:
STAT:DEV:MB0 :TEMP:DEV:DB1 :TEMP:DEV:MB1 :HTR:DEV:DB2:HTR:DEV:DB3
:AUX:DEV:DB4 :LVL
This message indicates that there are two temperature sensors, two heaters, one
auxiliary I/O board, and one level sensor.
10.3.4.2 Addressing a temperature sensor
To address a temperature sensor, use the following structure:
DEV:<UID>:TEMP
Where <UID> is a unique identifier that is allocated to each board, based on its SPI
location.
The configuration settings for a temperature sensor are:
TEMP Temperature sensor designator N/A
MAN Manufacturing designator N/A
HVER Hardware version Read only version number
FVER Firmware version Read only version number
SERL Serial number Read only alphanumeric
