Sensor Connection
Aanderaa offers a wide range of cables for different use of the sensors, both standard cables
using AiCaP or RS-232 but also special customer specified cables for use in project. See
chapter
9.6
for an overview of standard cables or contact
aanderaa.sales@xylem.com
for more info. To
configure the sensor, it needs to be connected to an Aanderaa logger using AiCaP, a real-time
RS-232 cable or a RS-232 configuration cable.
1.5.1 Configure sensor using RS-232 configuration cable
Connect your sensor to one of the COM ports on your PC. If your PC comes without serial ports
(COM ports) you may also use an USB to Serial Adapter. We then recommend the Tripp-lite
Keyspan Model USA -19HS
The 3855 cable is a non-watertight 1.5-meter cable for laboratory use only used for connection
between sensor and PC in the office/lab. This is a standard cable that can also be used to
configure most other Aanderaa Smart Sensors as well.
The cable is supplied with a USB port providing power to the sensor from the PC USB port. A USB
extension cable is supplied with the cable so alternatively you may connect the free end to an
external power (6-14V). An alternative solution is
to use a 9V alkaline battery (6LF22) to set the
sensor up or log it in the laboratory.
Sensor Cable 3855 is also available in other lengths.
