- Page 10 For local power supply, a tripolar power pack should be used. If, in case of local power Figure 15: FSP module as separate sub-unit supply, the LT2MSKU-T is powered by a power pack other than the specified one (e.g. older 2-pole types without FPE / earthing conductor), the LT2MSKU-T needs additional grounding.
- Page 11 (strip) for contacting. For data transfer, only the transmission path (TXD), the receive path (RXD) and signal ground are used. Control and signalling lines are neither served nor ana- lysed by the LT2MSKU-T. The standard transfer rate is 56 kbps. The NRZ line code is used during transmission.
