Installation
Please plug the RS485-interface board into the place provided, which is located beside the display. In the correct position the holes of the
RS485-interface match with the thread holes of the CT box.
Now press the RS485-interface down to connect it with the CT. Use both M3x5 screws for fixing the board.
The RS485-interface provides a 2-wire half-duplex mode. Please connect terminal A of the interface with terminal A of the next RS485-
interface and so on. With the B terminals proceed as well. Exchange the blind screw on each CT box by the cable gland.
Make sure, that you always connect A to A and B to B, not reverse. You may run up to 32 CT units on one RS485-USB-adapter.
The 120R-switch has to be turned to ON at one of the connected CT units only.
Each CT unit connected to the RS485 needs a different multidrop address (1...32). Please adjust the address by pressing the mode
button until M xx appears in the display. Using the Up- and Down-keys you can change the shown address (xx). The address can also be
changed with the software. The setting for baud rate in the software must be the same as on the CT unit.
Stecken Sie die RS485-Interface-Platine in die dafür vorgesehene Aufnahme im CT, welche sich neben der Anzeige befindet. Die richtige
Lage ist erreicht, wenn die Schraubenlöcher des RS485-Interface mit denen des CT übereinstimmen.
