ASY Port

W-WAN mode
Checking the check box enables W-WAN mode
Initialisation string n
These parameters (Initialisation string 1, Initialisation string 2, Initialisation string 3) allow
you to specify a number of command strings that are sent to the wireless module each time
a wireless connection is attempted. These can be used to set non-standard wireless
operating modes.
Each string is prefixed with the characters “AT” before being sent to the wireless module
and they are sent to the wireless module in the order specified until an empty string is
encountered. For example, Initialisation string 3 will not be sent unless Initialisation string 1
and Initialisation string 2 are both specified. Initialisation strings are not normally required
for most applications as the unit will normally be pre-configured for correct operation with
most networks.
Hang-up string
In a typical wireless application the connection to the network is “always on” and under
normal circumstances it is not necessary to hang-up the wireless module. Under certain
circumstances however, the router may use the “ATH” command to try and disconnect the
wireless module from the network, e.g. if an incorrect APN has been specified and the
module is unable to attach to the network correctly.
This parameter allows you to specify an alternative hang-up string that is sent to the
wireless module when disconnecting a call. As with the Initialisation strings, it is not
necessary to include the “AT” as this is inserted automatically by the router.
Post hang-up string
This parameter allows you to specify additional “AT” commands that is sent to the wireless
module after it has been disconnected. As with the Initialisation strings, it is not necessary
to include the “AT” as this is inserted automatically by the router.
