3.6.2 RSSI traps
SMS Commands
•
SMS commands
•
Enable allows the ELPRO 645M to respond to received
SMS commands.
•
Disable causes SMS messages (that start with a slash) to
be accepted but quietly discarded.
•
Password
If nonblank, all commands require the password in the form
pw=password as one of the arguments. The pw prefix can
occur in any case (“pw=”, “PW=”, “Pw=”, etc.) but the pass-
word must be in the exact case as entered on the web page.
Allowed Senders
•
Sender 1 / Sender 2 / Sender 3
Commands can be restricted to be accepted only if they
arrive from one of up to three “friendly” SMS Sender
addresses, which can enabled or disabled as necessary.
Sender addresses are typically numeric digits only including
the country code prefix. Select the button for a Sender (1-3),
and then enter the address in the adjacent field. If all three
addresses are disabled, then commands will be accepted
from ALL senders.
•
Respond only to senders
For security, command responses, including error messages,
can be restricted to be returned only to the registered
Sender SMS addresses.
•
Replace country code
This allows you to change the country that the responder
uses, which can be useful when monitoring routers across
national borders.
•
With … in responses
The string you wish to substitute for the country code.
RSSI traps

strength (RSSI) falls outside of specified thresholds
