10 Operating Instructions Combics CAIXS2
Getting Started
Instead of an analog/digital converter (ADC), you could also install a data interface
to connect an intrinsically safe digital weighing platform or balance (e.g. an
IS......-X).
Connection using RS232 (Option A16)
1 CTS green
2 DTR brown
3 RxD yellow
4 TxD white
5 GND gray
6 GND
Connection using RS485 (Option A19)
1 RxD-TxD-P white
2 RxD-TxD-N yellow
3 GND gray
4 GND
3
Insulate unused cable ends
Connecting Intrinsically Safe Data Cables
Connect intrinsically safe data cables to COM 1 (RS232, RS485 or RS422 and
intrinsically safe control signals). For pin assignments on the data interface board,
see 66015-741-50.
External voltage supply for AP1
At AP1 connected IS platform requires an external
Voltage supply, see document 66015-741-50 Page 2/9.
