Maximum Trigger Rate – This setting determines how often the router will send a “relay event” message. If the relay
event is recurring at a rapid rate this setting will prevent an undesirable “flood” of messages. If Maximum Trigger Rate is
set to "Always" the relay input is operating in edge triggered mode. In this mode the router will invoke its assigned
service any time that the input transitions to the selected state. So if ON CLOSURE is selected an SMS is sent every time
that the contacts close. This means that once closure is sensed there can be no other closure event until the contacts are
first sensed to be open.
All other modes where Max Trigger Rate has a time value are level sensitive. So if the contacts close an SMS is sent and
then the state of the relay input is ignored for a defined period of time. For instance, if Max Trigger Rate is set to 5
minutes an SMS is sent and then the relay input is sampled again in 5 minutes. If the contacts are still closed another
SMS is sent. If the relay input is not closed the router reverts to monitoring the relay every second.
SMS Destination Address – The MIN (mobile phone number) or email address to which the SMS message will be sent.
MIN must be 10 numeric characters with no spaces or punctuation. Any email address in the form
Anything@Any_Domain will be accepted.
SMS Alert Message – The text of the message to be sent when the relay interface activates. Limited to 100 characters
maximum. Only printable ASCII characters in the range of 32 – 126 decimal (20 – 7E hex) can be included in the
message.
4.2.3 Configuring The Relay Output (Driver) Interface
This screen configures the connection characteristics of the relay output interface and defines the service associated with
this interface. Currently, the relay output interface can be activated by an SMS message or from a button that can be
defined on the Advertising screen described in the Services section.
Appendix A contains schematic information concerning the relay output configuration.
