In case of the OTOT-EM55XL the NEC-E is embedded and a connection between NEC-E and OTOT-EM55X has
been established internally. In order to enable the communication of an OTOT-EM55X/XL with a NEC, the RS485
slave port of the OTOT-EM55X/XL has to be connected with the RS485 master port of the NEC. The NEC Ethernet
