SMS Function SMS controller send an event SMS messages to up to 3 cell phones. Any cell phone can be used to send SMS commands to BR900. Mobile users can contact and request information from a BR900 GSM controller and up to users can receive notification of events. With the BR900 GSM controller you can use a mobile phone to: Monitor the status of equipment or systems Send control commands to remote equipment Receive notification of events to your mobile phone or WEB server (data logger version) Any BieneRemote GSM controller can be used to send SMS commands to other BieneRemote GSM controller for remote control. Any BR900 GSM controller can be programmed via SMS instruction. Input Signal Monitoring The BR900ST has digital inputs that can be configured as: 0 or 0 event input two inputs connect with pullup resistor to module power supply To receive SMS message by event on inputs, you need enter SMS message on a module (or SIM card) programming. The BR900ST has analogue input. 00V 0 bit resolution Analogue Input additional implemented onboard power supply voltage monitoring 5.5V maximum You can set minimum and maximum analogue signal threshold as events. Output Control The BR900ST has Solid State Relay outputs (30V/0.5A max) Optionally (30V/0.5A max) OpenDrain Mosfet Outputs instead of SolidState Relay output. These may be controlled with SMS messages from approved users. To set any output as you like, you need only to send an SMS message. Module to Module Control The BR900 supports ModuletoModule management with SMS command. Users and Administrator The BR900 supports up to 3 users. Each user can interrogate the device for the current I/O status. Users can be notified based on changes to each input. 3
Security The BR900 has a number of inbuilt security features. Caller ID security provide authentication for device interrogation and control. Alarm SMS messages can be sent to users when an input reaches an alarm state. The following setpoint configurations are available: Alarm when 0 or 0 event at digital input. Alarm when above set point at analogue input. Alarm when below set point point at analogue input. Alarm when inside set points point at analogue input. Module Programming/Configuration The BR900 can be configured (programming) remotely with SMS command. Configuration options include Alarm Message Content, Users and Administrators Phone Numbers and other.
