Analog and Switched Voltage

The Temperature/Humidity Sensor KPC 1/6 ME and the Pyranometer CMP3

transmit analog voltage which is measured at the DIFF-Ports of the Datalogger

CR1000.

Figure 1.23: Connecting to SE- and DIFF-Ports

Lambrechts Wind Speed 14557 transmits analog current. Anyway, this signal

is also measured at the DIFF-Port of the Datalogger CR1000 but has to be

transformed into analog voltage by using a high-precision shunt resistor of 100

Ohm. The Temperature Probe T107 has to be excited by the EX-Port because

of switched voltage and is measured at the SE-Port. For details see section

1.3.3 on page 42 and 45.

Serial Data

The digital pressure sensor PTB210 transmits serial data which are received

at the COM-Port of the Datalogger CR1000. For connection see section 1.4.6

on page 45 . For setting up like shown in section 1.2.6 on page 25 simply

connect to the RS232-Interface on your PC or Laptop according to ﬁgure 1.24

and start communication with a terminal program.

NOTE: Take care to use the right parameters for communication through

the serial line. (section 1.2.6 on page 25)
