Configuring NM-422ETH as Dual Converter
 
The NM-422ETH can be configured as a bidirectional RS-232 to TCP/IP converter and data distributor at the same time.

This can be done by setting SW1 of dip switch array (see DSWITCH in figure 4), located inside the device, to position “ON”

Function

SW-1

SW-2*

SW-3*

SW-4*

Selects transmission from active input to four general purpose ports, RS-232 and Ethernet interfaces

OFF

X

Selects transmission from Ina or Inb to four general purpose ports. Enables independent bidirectional data transmission between the RS-232 and Ethernet interface.

Note:
SW-2, SW-3 and SW-4 are intended for future use and should not be configured
 
Configuring Auto Pilot port
Autopilot port can deliver data either from RS-232 or the Ethernet interface by configuring jumper J1 located inside NM-422ETH (see figure 4).


Function

Jumper

Selects transmission to Auto Pilot port from RS-232

AP - RS232

Selects transmission fto Auto Pilot from Ethernet interface.
