4.1.2 D-Sub Connector
The 9-pin D-Sub connector provides connectivity for Modbus RTU slave units
via RS-232. These units are known as “devices” on Netbiter Argos.
Note that when using the D-Sub connector it will not be possible to use any protocol
simultaneously on the 12-pin terminal block.
4.1.3 Ethernet Connector
The RJ-45 socket provides the Ethernet network connection for
Netbiter EasyConnect EC150. This connector also supports Mod-
bus TCP via Ethernet, which can be used at the same time as Mod-
bus RTU units on another interface.
