8.4.2 Legacy monitor commands
8.4.2.1 Cn command - Set Control
The control command sets the power supply into LOCAL or REMOTE mode and determines
whether the GUI is locked or active. When the iTC is powered on, it defaults to the last known
state.
Allowed values of this command are:
C0 Local and Locked
The remote interface locks itself out and will no longer be able to
connect to the Mercury.
C1 Remote and Locked
The remote interface is enabled and the front screen is disabled for
all operations (only monitoring is enabled).
C2 Local and Unlocked
This state does not exist on the current version of Mercury, since the
local mode disables all incoming connections. Setting C2 is the
equivalent of setting C3.
C3 Remote and Unlocked
The remote interface is enabled and functioning, but it is also
possible to control the Mercury from the front screen.
In the C3 state, the GUI can be used to examine values on the display, but the values cannot be
changed. However, the Remote Access menu is active and can be used to switch to the C2
state to change values.
If a GUI button is tapped in the C3 state, the instrument does not respond to any remote
commands until the button is released. Instead, these commands are stored and performed
when the button is released. Computer programs should either be written to tolerate this delay,
or should set the instrument into the C1 state to disable the GUI controls.
8.4.2.2 Rn command - Read Parameter
The READ command allows the computer to interrogate a number of variables. The returned
value is always a decimal number.
Possible values for the command are listed below:
R0 Set temperature K
R1 Sensor 1 temperature K
R2 Sensor 2 temperature K
R3 Sensor 3 temperature K
R4
Temperature error
(+ve when setpoint>measured)
K
R5 Heater output (as % of current limit) %
R6 Heater output (approximate) volt
