What is a Rotronic USB to Serial Parallel Driver and Why Do You Need It?
5 use of the hc2-aw-usb probe o hygroclip 2 the hc2-aw-usb probe from rotronic can be connected to a hw4 pc or to the transmitter by a serial cable in order to measure the relative humidity or to measure the temperature. o the hygroclip 2 probes measure the relative humidity in the air space between the probe and the sample. the hygroclip 2 probes measure the relative humidity in the air space between the probe and the sample. this air space is bounded on the one side by the sample cup and on the other side by the hygroclip 2 probe. o for relative humidity measurement, the hygroclip 2 probe is put onto the sample. the message displayed on the probe (see illustration below) indicates the air relative humidity being measured and the value of this value on the display. the hygroclip 2 probe displays the temperature of the air surrounding the sample on the display. o example - the temperature in the room has been measured continuously and is displayed on the hygroclip 2 probe in the form of a graph.

notes: o rs485 the vertical bar is used to indicate that the command string is to be passed to another device connected by rs-485 (multi-drop network with a master and one or several slaves). upon receiving the string, the master device strips the vertical bar and sends the rest of the string to the rs-485 driver. depending on the device, the stripped string may also be sent to the pc. the software used by the pc should be designed so as not to confuse this string with an answer. o adr address 99 can be used temporarily to communicate with a single device of unknown address. this..
