Response
Description
format
T3 xxx yyy zzz Queries all three temperatures at once. Reports CG, SHG
and CS temperatures in tenths of degrees Celsius in a single
"xxx" is the CG T in °C/10
string. A space character separates the temperatures.
"yyy" is the SHG T in °C/10
"zzz" is the CS T in °C/10
pump : sss Turns the coolant pump on or off. When queried, it responds
with the on/off state of the pump.
where "sss" is "on" or
"off"
pmod: sss Queries or sets the coolant pump mode. Values can be:
where "sss" is "normal",
• 0: Normal mode—the pump will shut off if the coolant
"fill", or "drain"
level is low and cause an interlock.
• 1: Fill mode—the pump shuts off until the level is OK,
then it turns on again (this facilitates filling long coolant
umbilical lines).
• 2: Drain mode—level and flow are ignored, and the
pump stays on for thirty seconds at a time (the pump
can be re-started).
When queried, the response is a string representing the
present pump mode.
level: sss Queries the coolant level status
sss is either "low" or
"ok"
FLOW m.nnn lpm Queries the coolant flow rate in liters per minute (lpm)
where "mm.nnn" is the
flow rate
