5 Installation and Setup

The properties of the devices connected to testo CU-2 are specified in appendix A.2
4.5.2.

Additional Analog and Digital In- and Output Connector 20)

testo CU-2 is delivered with a female connector 20) which is shown in Fig. 4.5. This connector
can be plugged into the external signals port 4). It is equipped with solder pins which can be used
as contacts for different analog and digital inputs and outputs:
•
5 analog input signals (– 10...+10 VDC).
•
3 analog output signals which are configured by the testo NanoMet software
(0...+10 VDC).
•
a digital input signal (0 or 5...25 VDC) which can be used to trigger data logging
•
2 digital alarm outputs delivering a 24 VDC signal in case of an error detected by the
testo NanoMet software. These alarm signals are also configured individually by the testo
NanoMet software.

The pin assignment of the external signals port 4) and the specific connector 20) is described in
chapter 8.3.
5 Installation and Setup
Note: Numbers – e.g. 2) = testo ASET15-1 interface – refer to the operating elements illustrated
in chapter 4.5 and appendix A.3.

Hardware Setup

There are no big efforts to install testo CU-2 and combine it with testo MD19 Rotating Disk Diluter
and testo ASET15-1 Air Supply / Evaporation Tube.
Simply use standard 25 pin D-Sub cables to connect these devices to testo CU-2. The remote
control interface connector of the stand-alone testo MD19-3E is located at the rear side of the
testo MD19-3E laboratory case. If testo MD19-3E is integrated in an testo ASET15-1, the
interface connectors of both components are situated at the rear of the testo ASET15-1 case.
Both interfaces have to be connected to connectors 2) and 3) at the rear side of testo CU-2.
If analog input signals should be recorded or provided by testo CU-2, these external devices
might be connected to the external signals port 4), using a standard 25 pin D-Sub cable with
female connector, or using the external signals connector 20). Two alarm voltage signals can
also be tapped from the external signals port 4) and a trigger signal can be applied to start and
stop data logging. The pin assignment of the external signals port 4) and therewith the
connector 20) is described in chapter 8.3.
Connect the testo CU-2 to your computer network or directly to a host computer using a
crossover network cable, if the system should be remote controlled via Ethernet, use a 9 pin
RS-232 cable to connect it to an AK host computer, or add a VGA monitor, keyboard and mouse
to work directly on the testo CU-2.
The different operation modes are described in chapters 5.3 and 5.4.
