2 SSI-USB Brief English Version Seite 2/6 1 Preface The SSI-USB-module offers flexibly programmable interfaces. The module connects to a host computer via USB or 3V3-RS232. The module implements an encoder-interface to the application complex via three RS485- transceivers. Using dedicated firmware-options, different interfaces can be represented, e.g. SSI, ABZ, RS485. Usually the module is powered via USB, alternatively via the 3V3-RS232 or the encoder-interface. 2 Applications User specific funktions User specific functions become possible through a powerful embedded controller. We re looking forward to your inquiries. Standard applications are: SSI Encoder-Simulator - USB-/3V3-RS232 to SSI converter - Hardware requirements o SSI-USB-v1.0 o 3V3-RS232: SSI-USB-v1.0-o1 - Communications protocol according to IB Kirchen SSI-Encoder-Simulator o Refer to Bedienungs- und Programmieranleitung für den SSI-Encoder-Simulator 4) Serielle Schnittstelle o Possible data rate is e.g.. 32bit 2MHz ABZ Encoder-Simulator - USB-/3V3-RS232 to ABZ converter - Hardwarevoraussetzungen o SSI-USB-v1.0-o2 o 3V3-RS232: SSI-USB-v1.0-o1-o SSI to USB-Seriell-Converter - SSI to USB-/3V3-RS232 converter - Hardware requirements o USB: SSI-USB-v1.0 o 3V3-RS232: SSI-USB-v1.0-o USB-/3V3-RS232 to RS485 converter - USB-/3V3-RS232 nach RS485 converter - Hardware requirements o SSI-USB-v1.0-o2 o 3V3-RS232: SSI-USB-v1.0-o1-o2
