CWH1000 Wireless Hub Product overview CWH1000 CAN Wireless Hub The Danfoss CWH1000 CAN Wireless Hub provides a gateway between the WMSS1000 Wireless Multi- Sonic Sensors and the machine controller by transmitting and receiving data to and from the WMSS1000(s). Dual radio modules allow redundancy for improved communication robustness. The CWH1000 is easily integrated into CAN bus systems.
User liability and safety statements OEM responsibility The OEM of a machine or vehicle in which Danfoss products are installed has the full responsibility for all consequences that might occur. Danfoss has no responsibility for any consequences, direct or indirect, caused by failures or malfunctions.
Technical Information CWH1000 Wireless Hub Conformance and compliance CWH1000 compliance statement IC: 5969A-PROFLEX1; FCC ID: TFB-PROFLEX1 This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
CWH1000 theory of operation The CWH1000 CAN Wireless Hub is paired with up to (10) WMSS1000 Wireless Multi-Sonic Sensors at a time. The hub collects data from all of the sensors and transmits this data on the CAN bus acting as a wireless gateway between the sensors and the machine CAN bus.

51.7 [2.03] 47.1 [1.85] P200 121 CWH1000 mechanical installation The CWH1000 contains radio antennas. For best performance follow the guidelines listed below. The CWH1000 should be mounted: • In a central location on the machine with respect to the wireless sensors.
There is a 0.68 uF capacitor and a 1 Ohm resistor in series to ground on this input for CAN shield termination. Configuration Input RCONFIG_1 Configuration resistor sets source address, see Setting the CWH1000 source address for further information. L1321661 • Rev AA • Mar 2014...
Technical Information CWH1000 Wireless Hub Recommended machine wiring guidelines 1. All wires must be protected from mechanical abuse. Wires should be run in flexible metal or plastic conduits. 2. Use 85˚ C [185˚ F] wire with abrasion resistant insulation. 105˚ C [221˚ F] wire should be considered near hot surfaces.
During power up, the CWH1000 checks a switchable internal parameter to see if it should operate in configuration mode or run mode. If the CWH1000 is set to configuration mode, it will initialize to the configuration channel and listen for any free sensors not already in a channel group.
CWH1000. The minimum number is 0 and the maximum number is 10. If the number of paired sensors is less than the Max Sensor number or if one of the wireless sensors is turned off, the CWH1000 will still transmit out the missing sensor’s respective CAN packets in run mode but will fill the data fields with 0xFF to signify a missing sensor.
Setting the Max Sensor value lets the system detect several error conditions, such as a loss of a sensor during operation or accidentally assigning two sensors the same machine position (PLID). Pairing CWH1000 to WMS1000 and a machine position WMSS1000 position on the machine To assign a WMSS1000 Multi-Sonic Sensor to a given position on a machine, the sensor must be assigned a PLID (Programmable Location ID) number.
