1. Introduction
This Command Line Interface (CLI) is provided for you to congure
the Areca SAS RAID controller expander functions. The CLI is useful in
environments where a graphical user interface (GUI) is not available.
• Locations of RS-232 Port
• Establishing the Connection for the RS-232 Port
The CLI function can be done by using an ANSI/VT-100 compat-
ible terminal emulation program. You must complete the appropri-
ate installation procedure before proceeding with the CLI function.
Whichever terminal emulation program is used must support the
XMODEM le transfer protocol.
The serial port on the SAS RAID controller’s bracket can be used
in VT100 mode. The provided interface cable converts the RS232
signal of the RJ11 connector on the SAS expander controller into
a 9-pin D-Sub male connector. The rmware-based terminal SAS
expander management interface can access the expander through
this RS-232 port. You can attach a VT-100 compatible terminal or a
PC running a VT-100 terminal emulation program to the serial port
for accessing the text-based setup menu.

1.1 Expander RS-232C Port Pin Assignment
To ensure proper communications between the SAS RAID controller
expander and the VT-100 Terminal Emulation, Please congure the
VT100 terminal emulation settings to the values shown below:
1.2 Start-up VT100 Screen
By connecting a VT100 compatible terminal, or a PC operating
in an equivalent terminal emulation mode, all CLI administration
functions can be exercised from the VT100 terminal.
There are a wide variety of Terminal Emulation packages, but for
the most part they should be very similar. The following setup pro-
cedure is an example Setup VT100 Terminal in Windows XP system
using Hyper Terminal use Version 3.0 or higher.
Step 1. Open the “Taskbar Start”/”Programs"/"Accessories"/"Com
mmunications"/"Heyper Terminal". (Heyper Terminal requires ver-
sion 3.0 or higher)
The controller RJ11 connector pin assignments are dened as be-
low.
Pin Assignment
Pin Denition Pin Denition
1 RTS (RS232) 4 GND
2 RXD (RS232) 5 GND
3 TXD (RS232) 6 GND
