CONFIGURATION
12 USB to IP gateway
That function is available only on the IPRS-1201
12.1 Principles
The IPRS-1201 provides a USB to IP gateway.
It is able to forward IP traffic from devices connected to the Ethernet
network to a USB device.
On the USB interface, the IPRS-1201 behaves like a USB host and a PPP
client.
The USB device connected to the IPRS-1201 USB interface must behave
like a PPP server.
Destination IP address; main case
When a device, connected to the Ethernet network, needs to transmit
data to the USB device, the destination address of the IP frames which
need to be transmitted to the USB device must be an additional IP
address assigned to the USB gateway IPRS-1201 (see the configuration
below).
Destination IP address; Modbus case
If no specific IP address is assigned to the USB gateway (see below), the
IPRS-1201 forwards only modbus TCP traffic to the USB interface.
The destination IP address of the IP frames must be the LAN IP address
of the IPRS gateway.
