Ultrasonic Sensor Group Control: How to Update 32 Sensors at Once

Re-configuring a network of up to 32 Senix ultrasonic sensors is easily done with Group Control, one of the features in SenixVIEW software. Group Control saves the time and effort required to connect to individual sensors and make multiple changes. It allows rapid cloning of whole networks from trusted file sources. It insures there are no missed parameters when updating several sensors. And it gives communication assurance in the process.

Networking ToughSonic Ultrasonic Sensors

There are only three requirements to network ToughSonic sensors:

  1. All sensors must use the RS-485 serial interface and have a similar Baud rate.
  2. Each ultrasonic sensor must have a unique network address between 1 and 247.
  3. All sensors’ serial data wires must be bussed in an end-to-end node network (no circle or star arrangements). The bus should have terminal resistance across the two data lines at each end.

This illustration shows two of a potential 32 sensors in a wired network using the Senix UA-TS-TB Termination board at each sensor location. With this arrangement, individual ultrasonic sensors can be viewed and reconfigured one at a time using SenixVIEW configuration software, or all at once using SenixVIEW’s Group Control feature.

Note: a single DC power source can supply the network at any location. DC power is distributed to each node by the 4 wire network terminals on the boards. It is important to make sure that the single DC supply has the capacity to support the sum of all sensor current requirements on the network.

SenixVIEW Group Control

Once an individual ultrasonic sensor has been configured to the user’s liking, a copy of its configuration can be filed on the user’s PC for reference. A network of sensors can be cloned using Group Control. The Group Control source can be the configuration of a specific ultrasonic sensor sensor or the stored file in SenixVIEW. The user can select which parts of a configuration to update across the network.
