GPRS Cellular Port Configuration

MultiConnect AW Security

Option Default Selection

O) PhyTimeout (Min)

15 Min

The Physical Time out option is a time limit in which

the MultiConnect AW will drop the connection to the

cellular network if no activity is sensed on the

network. The range is zero to 255 minutes, with 0

disabling the time out. The default is 15 minutes.

Normally, this option should be left in the default

value.

P) DLE Mode

DLE Mode 0 is enabled, no specific process is

needed on [ETX] characters. This means that is not

possible for a host to request an end of connection

or to receive a clear indication of the end of a

connection from the TCP/IP stack.

DLE Mode 1 is enabled, the [EXT] characters

means a request or an indication of end of

correction. As a consequence, [EXT] characters that

belong to the payload must be sent by the host on

the serial port preceded by a DLE character.

Similarly, EXT characters received by the TCP/IP

stack from the Internet are sent to the host through

the serial port preceded by a DLE character.

Q) TCP TxDelay 100

milliseconds

This option determines the time delay introduced

before sending a TCP frame that has not been

entirely filled with user data. The time is entered in

milliseconds, and it should be noted that a value of 0

initiates the sending of a TCP frame as soon as

possible after the reception of a single character

value from the host.

R) Handshake TimeOut

(sec)

90 seconds

The handshake timeout is a wireless modem

timeout of between 1 and 255 seconds. Default is 90

seconds.
