Installation

2.Install all electronics wiring according to the applicable sections 5.4, 5.7.x, and 5.8!

3.Plug the RS485/RS232 interface converter into your computer’s serial port, or attach it to a serial cable connected to the computer! Use 9 pin to 25 pin converter if necessary!

4.If the 9 VDC power supply is used, apply power to the RS485/RS232 converter!

5.Apply power to the FA/FR sensor!

6.Turn on your computer!

You need to make sure another serial device (e.g. an internal modem) is not using the identical COM‐port at the same time!

Always make all electrical connections before applying power to the FA/FR sensor! Do not change RS485 or power connections on the RS485/RS232 converter while the FA/FR sensor has power applied, as this may cause damage to the Interface converter!

5.7.1 Multidrop Installation (4‐Wire)

In 4‐wire multidrop installations the data can be transferred in both directions, from sensor to PC and reverse.

5.7.2 Multidrop Installation (2‐Wire)

Using the 2‐wire installation saves 2 wires in comparison to the 4‐wire installation. The disadvantage is, that the data transfer can be only in one direction at the same time.
