Configuring UC-7110

ATTENTION

If dial out fails, the pppd connection will be blocked, and the user will need to shut down the pppd, and re-dial. Since the return value is always OK (regardless of whether or not the connection is blocked), the AP must be set up to check the network status to determine if the connection is complete.

Dial-in Service

Direct cable connection:

yUse either of the following:

/>pppd <Local_IP_Address>:<Remote_IP_Address> /dev/ttyM1 38400 local crtscts

or

/>pppd <Local_IP_Address>:<Remote_IP_Address> /dev/ttyM0 38400 local crtscts login auth

Connect Using a Modem:

yUse:

/>pppd connect ‘chat –v AT CONNECT’

<local_IP_Address>:<Remote_IP_Address> /dev/ttyM0 38400 crtscts login auth

Configuring PPPoE

PPPoE relies on two widely accepted standards: PPP and Ethernet, which permits the use of PPPoE(Point-to-Point Over Ethernet).

PPPoE is a specification for connecting users on an Ethernet to the Internet through a common broadband medium, such as a single DSL line, wireless device or cable modem, used by many ADSL service providers. All users on the Ethernet share a common connection, so the Ethernet principles that support multiple users on a LAN combine with the PPP principles, which apply to serial connections.

yCreate the Connection:

/>pppd pty "pppoe -I <ETHERNET_INTERFACE> -m 1412" user <USER_NAME> password <USER_PASSWORD>&

<ETHERNET_INTERFACE>: Ethernet card connected to ADSL modem, for example, eth0

<USER_NAME>: User account, for example, moxa@adsl.net

<USER_PASSWORD>: Password for user account

If the PPPoE is successfully connected and get IP, you may check by the command below.

y/>ifconfig ppp0

How to Mount a Remote NFS Server

Currently, UC-7110 only supports NFS (Network File System) clients. Users can open NFS service on a Linux PC for UC-7110 to push data to. UC-7110 can use NFS to mount a remote disk as a local disk for data or log purposes.
