Connection via 9-pin D-Sub Connectors
D-Sub connectors can be implemented as an option. In this case, only 10Base-T and
100Base-TX are supported,
no Gigabit Ethernet connection
. In addition, the D-
Sub connector for LAN3 replaces not only the LAN3 RJ45 but also the COM1 RJ45
connector. These two interfaces are routed to one D-Sub connector.
Connector types:
• 9-pin D-Sub plug according to DIN41652/MIL-C-24308, with thread bolt UNC
4-40
• Mating connector:
9-pin D-Sub receptacle according to DIN41652/MIL-C-24308, available for rib-
bon cable (insulation piercing connection), hand-soldering connection or crimp
connection
