Applicability:
This manual applies to all HC2A probes with firmware version 1.x. Changes to the last digit of the version
number reflect minor firmware changes that do not affect the manner in which the probe should be operated.
1 Overview
The HC2A series are digital humidity-temperature probes based on the AirChip3000 technology. These probes
feature a UART serial interface and two 0…1 V linear analog output signals.
The HC2A probes are designed for use with the HygroClip2 generation of ROTRONIC humidity-temperature
instruments: transmitters, data loggers, hand-helds, etc.
The HC2A probes can also be used as a stand-alone device using either the analog output signals or the probe
digital interface. Connectors, cables and digital interface adapters are available to this purpose. Digital
integration with OEM applications is facilitated by the probe communication protocol options.
The HC2A probes offer the following user functions:
oUser configurable settings
oCalculation of the dew or frost point
oHumidity temperature calibration and adjustment
oSimulator mode
oData recording
The ability for the user to easily update the AirChip3000 firmware means that the HC2A probes can be kept up-
to-date regarding any future functionality improvement.
Available in different configurations, the HC2A probe series is designed to meet the requirements of a large
number of applications and environments.
1.1 Hardware and software compatibility
The HC2A probes are compatible only with the AirChip3000 generation of ROTRONIC humidity-temperature
instruments.
Configuration of the HC2A probes and access to the probe functions requires a PC with the ROTRONIC HW4
software version 3.7 or higher or connection to a compatible instrument from ROTRONIC.

2 Models
In the following tables, we have indicated the type of instrument primarily used with each probe model. The
following should also be noted:
oThe HC2A probes canbe directly connected to a PCor to an Ethernet network using one of the available
digital interface adapters (see separate document E-M-HC2-accessories).
oThe HC2A Probes can also be used as a standalone device with two analog output signals. Different
connectors are available to this purpose (see separate document E-M-HC2-accessories).
Regardless of the probe model, the analog outputs signals are always scaled in the same way by the factory
(0…1 V = 0…100 %RH and 0…1 V = -40…60 °C). The user is responsible for reconfiguring the probe analog
outputs (requires the ROTRONIC HW4 software) and for providing power to the probe.

E-M-HC2A-V1_0.docx Manual
3 General description
3.1 Power supply
When a voltage source of 3.3…5 VDC is not available, the probe should be used together with a voltage adapter
(see separate document E-M-HC2-accessories) so as to provide 3.3…5 VDC to the probe. Use of a voltage
adapter allows powering the probe from a voltage source of 5 to 24 VDC or 5 to 16 VAC.
The HC2A probes are polarity protected by a keyed connector. There is no electrical polarity protection.
3.2 Measured parameters
The HC2A probe measures relative humidity with a ROTRONIC HYGROMER®HT-1 capacitive sensor and
temperature with a Pt100 RTD.
3.3 Calculated parameters
Using the ROTRONIC HW4 software, the HC2A probe can beconfigured by the user to calculate either thedew
point or the frost point.
3.4 Analog output signals
The HC2A probe features two 0…1 V linear analog output signals. The default factory settings are as follows:
Output 1: 0…1 V (humidity) = 0…100 %RH
Output 2: 0…1 V (temperature) = -40…60˚C
Using the ROTRONIC HW4 software any output signal can be made to correspond one of the following:
oRelative humidity
oTemperature
oDew or frost point
The scale of each analog output can be set within the numerical limits of -999.99 and 9999.99. If so desired,
any output can also be disabled (no signal).
The D/A converters used to generate the analog output signals feature a 16-bit resolution. The 0…1 V analog
output signals exhibit a small positive offset of 3 mV or less at 0 V.
Minimum load requirements apply to the external device orcircuit connected to the probe voltage outputs. These
requirements are defined in the “Operation” chapter.

3.5 Digital interface
The HC2A probe features a UART interface (Universal Asynchronous Receiver Transmitter) that allows two-
waycommunication with the probe. For connecting the HC2A probe to a PC, use a digital adapter cable AC3001
(see document E-M-HC2-accessories). The probe can also be indirectly connected to a PC using an instrument
from the ROTRONIC program.
The ROTRONIC HW4 software (version 3.7.0 or higher) allows full access to the following:
oMeasurement data (humidity and temperature) and calculated parameter (dew or frost point)
oProbe information: name, RS-485 address, humidity sensor status, etc.
oProbe alarm functions
oProbe data logging function
oProbe calibration and probe adjustment functions
oProbe configuration
oFirmware update of HygroClip2 probes
3.6 Communication protocol
The probe measurement data can be read without having to use the ROTRONIC HW4 software. The HC2A
probe offers the following communication protocol options (ASCII) which can be selected by connecting the
probe to a PC running the ROTRONIC HW4 software:
oRO-ASCII: this is the standard (default) communication protocol used by all AirChip 3000 devices and
by the HW4 software. In principle, this protocol supports all of the AirChip 3000 functions but some of
the functions require a certain amount of computations to be carried out by an external device such as a
PC.
oCustom: this communication protocol can be used to provide compatibility of the HC2A probe with an
existing communication system. The Custom communication protocol is limited to reading measurement
data from the HC2A probe. Functions such as device configuration, humidity and temperature
adjustment, etc. are not supported. The Custom protocol is applicable to all AirChip 3000 devices with a
digital interface and allows RS-485 networking
oI2C: The I2C protocol available with the HC2A probe does not allow the networking of devices and is
limited to a one way communication where the HC2A probe automatically sends data during each refresh
interval to an external device with I2C input.
When using either the RO-ASCII or the Custom protocol, the HC2A probe can be set to send data automatically
after each refresh cycle without requiring a data request.When this mode is enabled, the receiving device must
be listening at all times in order to get the measurement data.

3.7 Connector
All standard probe models of the HC2A series use the same keyed connector (male). The connector is located
either directly on the probe body or at the end of a cable. The probe connector is secured to the matching female
connector with a threaded collar.
