atiMgmtSysTempCtrl (1.3.6.1.4.1.926.1.3.2.4.1)
Value list Description
off(1) Temperature device is off. This setting is non-volatile, if the variable is in this state upon reset (or power-up) this value will be
retained. This is the DEFAULT factory value for this variable.
onTimer(2) Temperature device is turned on for a predefined time. Before a SET to this state is issued, atiMgmtSysTempTimer is to be SET
with the number of minutes the heater or cooler is to be on. When the timer has expired, this variable will automatically be set to 1.
onTemp(3) Temperature device is controlled by the battery temperature probe. Before a SET to this state, atiMgmtSysTempTemperature
and atiMgmtSysTempHysteresis must be set to the desired temperature values. Once placed into this state, this variable will not
change until another SET to this OID is received. Temperature control is based on the battery temperature probe. If there appears
to be no battery temperature probe, the output to the temperature device will be inactive.
onTimerTemp(4) Temperature device will be controlled by both the temperature and timer values. When set to this state, the temperature device will
be controlled as if this variable is in state 3, but only for the time defined by atiMgmtSysTempTimer. Once the timer has counted
down to zero, the value of this variable will be returned to 1. This value is volatile, after reset, the state of this variable will be 1 if it
was in this state before the reset.
on(5) Temperature device is on. This value can be used when the temperature device has a thermostat of its own. However it is recom-
mended, as a safety precaution, that state 3 is used with the battery temp probe being used as a backup in case the device ther-
mostat gets stuck in the "on" state (provided the transponder is connected to the temperature device’s power control). This state
/ mode could also be used if the temperature control line was used for something other than a temperature control. This value is
non-volatile and will remain in this state after a reset.
atiMgmtSysTempStatus (1.3.6.1.4.1.926.1.3.2.4.2)
Value list Description
contactOpen(1) The value of this variable reflects the state of the feedback signal from the temperature device. Since not all temperature devices
have a feedback signal, or the operation of the feedback signal may vary from device to device, the meaning of this signal is
implementation specific.
contactClosed(2)
atiMgmtSysTempMode (1.3.6.1.4.1.926.1.3.2.4.3)
Value list Description
heater(1) Mode of Operation. The temperature device may be a heater (such as a battery mat) or a cooler (such as an enclosure fan). When
this device is acting as a thermostat, this variable defines the active state. If this variable is set to "heater", the temperature device
will be active only when the temperature is below the defined level. If this variable is set to "cooler", the temperature device will be
activated when the temperature is above the defined level. The DEFAULT factory setting for this variable is heater(1). This variable
is non-volatile and its value will be retained when the device is reset.
cooler(2)
atiMgmtSysTempActiveState (1.3.6.1.4.1.926.1.3.2.4.4)
Value list Description
closed(1) This variable defines how this device creates the active state. When this variable is set to "closed(1)" the active state will be rep-
resented by the drive pin being shorted to ground and high impedance will represent the inactive state. When this variable is set
to "open(2)" the active state will be represented by the drive pin being high impedance in the active state and shorted to ground in
the inactive state. The DEFAULT factory state for this variable will be 1. This variable is non-volatile and the value will be retained
when the device is reset.
