Mounting Rail; Data Exchange - KLEIBER KPE 660/5 Betriebsanleitung

Cold tap water is usually sufficient for cooling. It should not be so strongly cooled that condensation develops
on the instrument. Take into account the environmental conditions (air temperature and humidity) with respect
to the cooling.

5.6 Mounting rail

There is a mounting rail under the instrument for fixing the pyrometer through which the pyrometer can be fixed
using various brackets.
We recommend fixing the pyrometer to the mounting rail using a clamp. This mounting plate ensures secure
assembly of the pyrometer as well as optimal adjustment with respect to the object being measured (for order
data see. (section 3.3) at page 6).

5.7 Data exchange

The pyrometer has a RS485 interface. The RS485 interface allows data exchange between the pyrometer and
a central processing unit (e.g. computer) using commands (see Command list (section 12) at page 33). The
interface works in half duplex, i.e. it can either send or receive. The interface is characterized by the following
parameters:
• 8 data bits
• 1 stop bit
• Even parity
• Baud rate adjustable (see Command list (section 12) at page 33)
The transmission with the RS485 interface is as far as possible not susceptible to interference, it is used for
very long transmission distances and one interface can be linked to up to 32 pyrometers in a bus system.
Connection example of RS 485 interface
Half-duplex operation A1 and A2 as well as B1 and B2 are bridged in the 12-pole circular connector of the
cable to avoid over-long branch lines and thus reflection and to avoid interrupting the RS485 data bus when
disconnecting a plug.The transmission rate of the interface (in Baud) depends on the cable length. Values
between 1,200 Bd and 115,200 Bd can be set. A benchmark for 19,200 Bd is 2 km total cable length. The
baud rate which can be used is halved with the doubling of the transmission distance.
