10 Interface Operation (with selector switch setting  OFF)
The calibrator is equipped with an infrared interface for communi-
cation with the PC. Commands are optically transferred through
the instrument housing by means of infrared light to an
interface adapter (accessory) which is attached to the calibrator.
The adapter’s USB interface allows for connection to the PC with
an interface cable.
Commands and parameters can be transmitted from the PC to
the calibrator. The following functions can be executed:
• Configuration and read-out of calibration parameters
• Calibration function and measuring range selection
• Start calibration
• Programming of user-specific procedures (interval and ramp
functions)
10.1 Activating the Interface
The interface is automatically activated for receiving operation
(calibrator receives data from the PC) as soon as the interface is
addressed by the PC, assuming that the “
1rStb” parameter has
been set to “on” (see section 10.2), or the instrument is already
switched on (the first command wakes up the calibrator, but does
not yet execute any further commands).
Switching the Interface On via the PC
After transmission of a data frame from the PC, the simulator is
switched on. Use the power pack for lengthy on-times for this
reason. This prevents automatic shutdown due to battery voltage
monitoring.
Operation in the REMOTE Mode
In the REMOTE mode, the device responds just like it does in the
local mode. The device is reset to local mode operation after
switching it off and back on again with the ON / OFF | LIGHT key.
10.2 Configuring Interface Parameters
1rStb – status of the infrared receiver in the stand-by mode
There are two possible switching statuses for the infrared
interface when the calibrator is switched off:
on: IR appears at the display and the infrared interface is
active, i.e. signals such as making commands can be
received, and power is consumed even though the
calibrator is switched off.
oFF: IR does not appear at the display and the infrared
interface is switched off; signals cannot be received.

Addr – address
If several calibrators are connected to the PC via an interface
adapter, a separate address can be assigned to each instrument.
Address number 1 should be selected for the first instrument, 2
should be assigned to the second and so forth.
