noax interface modules
W
ith a special adjustment to the noax interface modules, it is possible to apply a
supply voltage of +5 V or +12 V (max. 1.0A) at Pin 4 or Pin 9.
The Industrial PC has to be opened and the interface module has to be disassembled
in order to adjust the module.
The interface has to be marked in the connector area in line with the adjustment made
to it.
Interfaces that have been pre‐adjusted by noax at the factory are labeled accordingly in
the connector area.
Optional labeling of serial interfaces COM1 / COM2:
P4/5 V
RS232 interface with 5 V supply voltage output
(5 V at Pin 4)
P4/12 V
RS232 interface with 12 V supply voltage output
(12 V at Pin 4)
P9/5 V
RS232 interface with 5 V supply voltage output
(5 V at Pin 9)
P9/12 V
RS232 interface with 12 V supply voltage output
(12 V at Pin 9)
RS422DP
RS422DP interface with 5 V and 12 V supply voltage output
(Dual Power: 12 V at Pin 4 and 5 V at Pin 9)
RS485DP
RS485DP interface with 5 V and 12 V supply voltage output
(Dual Power: 12 V at Pin 4 and 5 V at Pin 9)
RS232ISO
RS232 interface galvanically isolated
(no supply voltage at Pin 4 or Pin 9)
On the interface module for the galvanically isolated RS232 interface, you
cannot set up a supply voltage at Pin 4 or Pin 9.
