Please read through this manual thoroughly to enable you to fully exploit the various features of your product. To the extent permitted by law Kistler accepts no liability if this instruction manual is not followed or products other than those listed under Accessories are used. -
Page 6: Warning Symbols And Their Meaning
Tips, extra information or important information. Death, personal injury or damage to your KiHUB could re- sult from connecting the wrong voltage to the wrong pins of your KiHUB connectors. Be extremely careful that you connect the correct voltages to the correct connectors as specified in this manual. -
Page 7: Protection Rating
1. Contact voltage proof. 2. Dust-protected: Ingress of dust is not totally prevented, but dust shall not penetrate in a quantity to interfere with satisfactory operation of the KiHUB or to impair safety. For proper dust protection all sockets should be either po- pulated with plugs or dust caps. -
Page 8: Installation And Operation
2.1 System overview Fig. 1: KiHUB, Type K3879BQ02 Type K3879BQ02 forms part of the new Kistler KiHUB communication device family developed to link Kistler on- board measurement systems and ATDs used in automoti- ve crash tests. Basic functions of KiHUB are: ƒ... - Page 9 KiDAU family devices. Ethernet twisted pair 100 MBit/s. Power is distributed from CL1 or trailing cable input via 7 A fuse.

Page 10: Kihub Functions
ƒ If the supply voltage exceeds 64 V, damage to your KiHUB will result The KiHUB has internal DC/DC converters that will opera- te from a power supply voltage of 20 ... 60 V. The maximum power consumption of a KiHUB with on-board adapter is 20 W (supplying maximum battery charging current). - Page 11 20 ... 36 V. Excee- ding this range may damage the CrashLink1 devices. The following figure shows the power distribution concept in KiHUB. Every loadable connector includes a 10 A fuse for system power segmentation/protection. DCDC Converter 13,2 V / 100 W output...

Page 12: Battery Power Backup
ƒ Do not mechanically damage the KiHUB In order to keep the battery operational, it is not necessa- ry to run any 'service cycle' or 'change cycle'. The KiHUB automatically charges the battery when needed by simply applying the operating power supply to the system. -

2 second pulse in the rest and will be forwarded to ATDs. The following figure depicts the KiHUB trigger infrastructure. The EXT connector converts the differential T0 bus to a low active signal which is pulled with 8 kΩ to 15 V. SR on the EXT connector is referenced to GND. - Page 14 KiHUB Type K3879BQ02 Typical dynamic values of the differential bus are: Units Min. active RX pulse 30 µs Min. active TX pulse Min. star point delay <33 µs Table 2: Typical dynamic values of the differential bus Trigger IN The trigger input 5-pin round connector contains SR and T0 trigger inputs suited for switches, open collector or open drain outputs.

Installation and operation 2.2.4.1 Trigger example Death, personal injury or damage to your KiHUB could re- sult from connecting the wrong voltage to the wrong pins of your KiHUB connectors. Be extremely careful that you connect the correct voltages to the correct connectors as specified in this manual. -
Page 16: Sr Trigger Event When Trailing Cable Is Unplugged
Trigger output setup 2.2.4.2 SR trigger event when trailing cable is unplugged KiHUB provides the possibility to be configured for an SR trigger event generation when the trailing cable is un- plugged from the system. This option is selected using a DIP switch present in KiHUB hardware. -
Page 17: Media Converter
2.2.5.2 Configurable Ethernet HUB function KiHUB provides the possibility to be configured as a pseudo Ethernet hub instead of the default Ethernet switch function. In this mode the Ethernet packets received in a given port are sent to the rest of Ethernet ports without checking the Ethernet switch address translation table. -

Page 21: Use Case 2
Installation and operation 2.3.2 Use case 2 This is the typical use case of KiHUB where only CrashLink2 devices are used. The power is applied via trailing cable and the communication works at 100 MBit/s. Power Supply and Comm 20 … 60 V Fig. -

CrashLink1 and CrashLink2 are safely powered within their specification. Power Supply and Comm 20 … 60 V Power Supply 20 … 36 V Fig. 13: KiHUB media converter and diode, CrashLink1 powered CrashLink2 powered (100 MBit/s).

Page 23: Use Case 4
In this case the power supply voltage must be in the range defined by CrashLink1 specification (20 ... 36 V). An extra fuse must be added to KiHUB in order to allow the power bridging from CrashLink2 to CrashLink1. Such hardware modification should be done by your Kistler customer support team. -
