Two-Way Communication Provides Improved Performance for Air Seeder Monitoring

Detecting air seeder blockages just became a lot easier with the DICKEY-john Daisy Chain Air Seeder Blockage System (DCBS). This system monitors seed and fertilizer flow on small and large air seeder implements and alerts of blocked or faulty sensors.

The Daisy Chain Blockage System architecture consists of a blockage module and daisy chain (serial communication) blockage sensors. Each module and sensor displays on the virtual terminal indicating critical system parameters for the selected loop. You can connect up to 4 modules and 8 loops.

Advanced diagnostics is a value-added feature to assist in quick identification of system issues relating to sensor, communication, and power issues of the Daisy Chain Blockage System. Alarm screens alert of system issues and exact problem location. The system's two-way communication allows for continued operation with pinched wires or breaks in communication lines to minimize downtime in the field. 

The system is compatible with any ISO virtual terminal including Dickey-john, Case, John Deere, and Agco terminals.


  • Maximum 4 Modules with 2 loops each (8 loops), 54 sensors per loop for total of 432 sensors

  • Tramline monitoring of seed and fertilizer with up to 192 sensors assigned to tramlining

  • Full screen alarms pinpoint blockage or system issues for quick resolution

  • Bi-directional communication lines between sensors and modules

  • System can continue to monitor blockage with 1 line failure

  • Three system tests (communication, power and sensor) provide immediate feedback of system status

  • Sensors come in 4 sizes (25mm, 32mm, 45mm and 50mm)

25mm Sensor - #46798-8885S1

32mm Sensor - #46798-8670S1

45mm Sensor - #46798-8865S1

50mm Sensor - #46798-8840S1

Daisy Chain Module - #46798-8690S1
