If the relay is set to
pulse
mode, it will automatically deactivate after a pre-
determined time duration. The time duration is set in increments of 10ms.
Therefore, if you wish the relay to activate for 1 second, you will set the “ON”
time to 1s ÷ 10ms =
100
. If a 2 second duration is required, you will set it to
200
,
etc. The time duration for each relay may be set by sending the following SMS
command to the device:
Relay 1:
**104*
time
E.g.
**104*150
Relay 2:
**105*time
E.g.
**105*200
As with the inputs, multiple commands may be strung together in one SMS (max.
160 characters) E.g:
**100*1**30*OPEN GATE**104*200
The command above will set relay 1 to
pulse
for
2 seconds
when the text “
Open
Gate
” is received from an authorised user.
Step 7:
The device may be programmed to send an automatic “
report
” SMS periodically
to the report destinations. It is advisable to make use of this feature (at least
weekly) to ensure that the account remains active on the cellular network. The
interval between report messages is set in increments of 1 minute. For example,
if you wish the device to send one message per week, the parameter must be set
to 1min x 60 x 24hrs x 7days =
10080
. The command to set this is as follows:
**114*
time
E.g.
**114*10080
Step 8:
The device can be set to send an alert if the
battery voltage
drops low. The
voltage can be set in 1V increments (**49) and the alert function must be enabled
(**48) at the same time. To set the device to send a low voltage alert, the
following SMS command may be sent to the device:
**48*1**49*
voltage
E.g.
**48*1**49*10
