Configuring W24 when in iRouter Mode
iRouter mode is terminated by any of the following occurrences:
• By issuing the AT+iSTPR (Stop Routing) command. When W24 receives this command,
routing services are stopped and W24 goes offline on the dialup/cellular side. If ARS=1
(Auto Routing), W24 automatically goes online and restores routing services when the next
packet arrives.
• Automatically after an idle time period (with no routing activity) has passed. The idle time
period is defined in the IATO (Inactivity Timeout) parameter. Idle time terminates routing
only if IATO has a positive value larger than 0. When IATO=0, idle time termination is
effectively disabled. If ARS=1 (Auto Routing), W24 automatically goes online and restores
routing services when the next packet arrives.
• By issuing the (+++) ESC string. W24 terminates iRouter mode and goes offline on the
dialup/cellular side. Following an ESC sequence termination, W24 does not restore routing
services even if ARS=1. To restore routing, either issue the AT+iSTRR command or,
alternatively, if ARS=1- issue AT+iDOWN.
Configuring W24 when in iRouter Mode
While in iRouter mode, W24 can be configured using the same methods for W24 in general (see
Figure 2-2):
• Assuming W24's website is enabled on the WiFi end, W24's internal configuration website
can be accessed by any browser that is connected to the same WiFi network.
• Assuming W24's website is enabled on the dialup/cellular side, W24's internal configuration
website can be accessed by any remote browser connecting to W24's port 80 over its public
IP address.
• AT+i commands coming from the host application.

AT+i Interface to W24
In addition to configuring the W24, AT+i commands can also be used to perform operations on
either the WiFi or dialup/cellular communication platform (see Figure 2-3).
Using the CPF (Communication Platform) parameter, you can select either one of the
communication platforms. When CPF=0, AT+i commands are directed towards the
