2.2 Global parameter configuration
Global parameters are parameters which apply to the system in general. Global parameters
are constant and do not change while device is working, unless they are configured by user
(Fig.2.2.1).
Protocol
is a formal description of digital message formats and the rules for exchanging
those messages between system’s elements. This parameter sets how FM-Xxx3 device
communicates with server. Options:
•
UDP – consumes less traffic (amount of data send/received), but less reliable.
•
TCP – consumes more traffic (about 30% more), but more reliable.
In case of UDP, if data is lost during transfer to server, the device will repeat the same message in
next GPRS session, until transfer is successful. This means that in case of UDP there will be more
retries to send, but server will receive all the data anyway.
APN
(Access Point Name) is a communication protocol that allows a user's device to
access the internet using the mobile phone network. Name, User and Psw (password) parameters
should be provided by your mobile operator as GPRS settings.
Connection settings
:
•
IP1 – Internet Protocol address of your server in Ipv4 form (i.e.
127.0.0.1
)
•
Port1 – port number through which server is accessible (i.e. 7001)
Configuration Password
– password which restricts device configuration through USB
cable. When not blank, you will be asked to enter password every time when you start receiving or
sending configuration session with device. Leave it blank, if you want everyone to be able to
configure your device. If you forget the password, you can reset or delete it by sending
configuration via GPRS from your server account, because then you wont be requested for
password.
SMS
are group of settings to manage your device via SMS messages. Click “Options” to
see them (Fig. 2.2.2). FM-Xxx3 device can accept and send specific SMS messages, like device
location information or status. In order to prevent third party eavesdropping you can restrict their
usage to up to 10 authorised numbers with one password for all of them. Device will receive and
send SMS messages only from those Valid Numbers. Numbers are written without spaces and
without plus sign in front (i.e.
37012312345678
). Leave them blank, if you want to allow everyone
to send SMS to the device. Every request with SMS must be sent with password, if device is
protected. Leave blank, if not using this feature.
Warning! If you leave authorised number and password fields blank, 3
