Table 2.9: Serial Communication Port Conﬁguration

Note: For applications where D-Sub connectors are preferred rather than the default RJ45 connector,

a front panel is available whereby all serial ports can be connected via mini D-Sub connectors.

2.8.1 Ethernet/SER4 Port

If a network interface such as Ethernet or a ﬁeldbus is required, the most upper port on the front panel

can be used. This port based on SCC1 of the 68360 is physically conﬁgured by a so-called SI Piggyback.

SI Piggybacks are available at the moment for the 3 standard Ethernet versions 10Base5 (AUI), 10Base2

and 10BaseT. Additionally, an isolated RS485 interface is available with 9-pin D-Sub frontpanel con-

nector which is especially designed for Fieldbus applications available as well as a standard RS232 in-

terface. for more information, please refer to the SI Piggyback Appendix in this manual.
