2.5.4 Connecting to the RS-232 Control Port(s)
To connect a remote unit to the HE4000 through the RS-232 control port, a cable is needed that
is the appropriate length for the application. Because the HE4000 is a DTE device, a NULL
modem cable or adapter is required to connect to it. The cable must be made to the following
specifications:
•
RS-232 electrical.
•
DB-9 female connector on one end.
•
An appropriate connector for the remote unit on the other end.
Using the direct connect cable provided with the HE4000, attach one end to a remote unit and the
other end to the RS-232 control port.
2.5.5 Ethernet Control Port
The Ethernet control port is an RJ-45 connector. Remote control using this port requires the
following:
•
Embedded Web Browser
•
Telnet
