External PAD Settings

PAD Mode
Select button to set the PAD mode of the modem as a Server or Client. In Client mode, the modem will initiate an
outbound connection to the Remote Host IP Address with the Outgoing Port based on the selected DTR setting. In
Server mode, the modem will accept one incoming connection on the specified Incoming Port. The modem will
not accept multiple incoming connections at the same time – additional connections are arbitrated based on the
Server Session Closed On and Timeout parameters. Note: It is possible to override Server mode and make an
outgoing client connection using the RS-232 command set.
atd*xxx.xxx.xxx.xxx:yyyyy – When in server mode, and no connection is active, the atd* command (followed by an
IP address) can be issued to initiate an outbound client connection to the specified IP address and port as specified
after the colon. If no port is specified, the port number used is the Outgoing Port parameter. To hang-up such a
connection, 3 ‘+’ characters must be inserted into the outgoing stream (“+++”). The modem will return to
command mode once it has seen the “+++” and respond with OK. The connection can then be broken by entering
“ath”. The modem will return to server mode. Such a client connection can be repeated again as necessary, as
long as each connection is hung-up before a new one is made.
Additional note: The modem is capable of only 1 PAD connection at a time. When a manual client connection is in
progress (atd*xxx.xxx.xxx.xxx), a connection attempt by an incoming client may result in the disabling of the PAD
function until the next device reset.

Pad Protocol

support either type of client.

Incoming Friendly IP Address
