Serial Interface; Temperature Probe - WIKA CTH6200 Betriebsanleitung

4. Design and function

4.5 Serial interface

For the data transfer to a computer, only use the interface cable from WIKA. These are
suitable for connection to a USB interface (USB driver needed) or an RS-232 interface.
USB interface cable
The USB interface cable consists of a USB connector (model A) at one end of the cable
and a 3.5 mm stereo jack connector at the other end of the cable.
The cable is approx. 2 m [6.6 ft] long.
RS-232 interface cable
The RS-232 interface cable consists of a 9-pin Sub-D female connector at one end of the
cable and a 3.5 mm stereo jack connector at the other end of the cable.
The cable is approx. 1.5 m [4.9 ft] long.
Interface converter
With an galvanically isolated interface converter, the instrument can be connected to
an RS-232 interface of a PC (USB adapter possible on request) in order to visualise the
data with the WIKA data logger evaluation software GSoft. The transmission is protected
against transmission errors by extensive safety mechanisms (CRC).

4.6 Temperature probe

CAUTION!
Damage to the instrument
If third-party temperature probes are used, they can damage the hand-held
thermometer and the temperature probe.
