To achieve an improved RSSI the standard antenna can be upgraded to a model with
higher gain and/or the antenna should be positioned in an area with less physical ob-
struction. An extension lead can be attached to the SMA connector on the PCB to lo-
cate the antenna away from the control unit housing.
5.3 Power Up/Reset Text Message
The system can send an message to all the text numbers when a system reset or power
up has occurred. This can be due to network failure or power cycling (power off followed
by power on). Note the system repeatedly resets during network outage. You will only
receive 1-message after a network outage.
RSMS Enable enables the reset text message
RSMS Disable disables the reset text message
PSMS Enable enables the power up text message
PSMS Disable disables the power up text message
5.4 SIM Card Balance Checking and Service Data Forwarding
The system is able to forward SMS messages and Service Data which networks use to dis-
play remaining air-time minutes or credit. The forward function can also send network
data used to register a SIM with the network website. All forwarded data is sent to the
phone which set the service up. The forwarding service can be permanently enabled to
forward all unsolicited messages from unrecognised numbers (i.e. not user or master num-
bers) to the forwarding phone number. However, to stop excessive ‘spamming’ and
wasting credit, the service can be enabled in temporary mode limiting to forwarding
messages for only 3 minutes after a master user has sent a valid message (typically the
SMS or DIAL command). Additionally only one message will be forwarded every minute
to ensure excessive numbers of messages are not sent.
Forward Enable Forwarding service permanently enabled
Forward Temp Forwarding for up to 3 mins after a valid messaged received only
Forward Disable No SMS/Service Data Message forwarding
Networks require either a SMS text message to be sent to retrieve a balance or a network
code to be dialled. Please check with your network to find your balance checking
method.
5.5 Forwarding SMS Messages to any Number
Typically the SMS command is used to forward a SMS text to the network to request a
balance. However the SMS function will forward the text to any number specified.
SMS <number>,<text>.
Typical example (Orange, T-Mobile Balance Request)
SMS 150,Balance sends ‘Balance’ to 150
This will text ‘Balance’ to number 150. Please note you need to ensure the forward ser-
vice is set up as above to receive a reply from the system
For network which require a code to be dialled use the DIAL for example Vectone UK:
DIAL *102# dials ‘*102#’ for a balance request (see section 4.10 Dial Now)
