UDP Point to Point
UDP Point to Multipoint
TCP Client/Server
When TCP Client/Server protocol is selected, IP920 is set in a combined
mode. It can take initiative to create a TCP connection when data is
received from a serial port and no TCP connection already exists; it can also
passively wait for a remote TCP client to create a TCP connection and pass
serial data back and forth. See TCP Client and TCP server for details.
UDP Point to Point
When UDP Point to Point protocol is selected, IP920 transmits serial data to
a specific point with UDP packets. It also accepts UDP serial data from that
particular node.
Remote IP Address:
a remote IP address to which UDP packets are sent by
the IP920 when data is received from a serial port.
Remote Port: a remote UDP port to which UDP packets are sent by the
IP920 when data is received from serial port.
Listening Port: a UDP port the IP920 unit listens to. UDP packets received
on this port are transmitted to the local serial port.
UDP Point to Multipoint (P)
This protocol is set on the unit who sends multicast UDP packets.
Normally, this unit is the master radio of a network.
Multicast IP Address:
a valid multicast address this unit uses to send
multicast UDP packets upon receiving data from serial port. 224.1.1.1
Multicast address is a good example.
Multicast Port: a UDP port this base station sends UDP packets to.
Multipoint stations should listen to this port in order to receive multicast
packets.
Listening Port: a UDP port the base station uses to accept data from
multiple remote units.
Time to Live: TTL for multicast packets.
UDP Point to Multipoint (MP)
This protocol is selected on the units who receive multicast UDP packets.
Normally, this protocol is set on remote units.
Remote IP Address:
a remote IP address to which UDP packets are sent by
this IP920 when data is received from serial port. Normally this is set to the
IP address of the Master unit.
Remote Port: a remote UDP port to which UDP packets are sent by this
IP920 when data is received from serial port. Normally this port number
matches Listening Port of a UDP Point to Multipoint (P), typically the
master.
