5.4 Pair Connection Mode
Pair Connection Mode uses two NCOM devices in tandem, with one NCOM device in
Pair Connection Master Mode and the other in Pair Connection Slave Mode. Two
NCOM serial device servers are then connected to each other through Ethernet.
Both may either be connected to the same LAN or over a WAN (i.e. through one or
more routers). Pair Connection Mode transparently transfers both serial data and
modem control signal without distance limitation.
When setting two NCOM-113-M devices in Pair Connection Mode, you need to set
the “Destination IP Address” of the master serial device server as the IP address of
the slave serial device server.
Under the “HOME” page of NCOM-113-M’s firmware, select “NETWORK SETTINGS”
to find the “Port 1 Mode Settings” window. Under “Mode”, select “Pair Connection -
Master” and type “Destination IP address” and “Port” of the slave serial device
server respectively (e.g. 192.168.254.250 Port: 2000) to connect to a serial device
server in Pair Connection Slave Mode. Check the “Make these the default settings”
box and click “Apply Changes” to set two NCOM-113-M devices in Pair Connection
Mode.
