DA-660/662 Hardware Hardware Connection Description
3-3
Connecting the Power
To power on the DA-660/662, use a power cord to connect the power line to the DA-660/662’s AC power
connector. The power connector is located on the right side of the rear panel. Next, turn on the power switch.
The DA-660/662 takes about 30 seconds to boot up. Once the device is ready, the Ready LED on the front panel
will light up, and the DA-660/662 model name and firmware version will appear on the LCD screen.
Connecting to the Network
For DA-660 and DA-662, connect one end of the Ethernet cable to one of the DA-660/662’s 10/100M Ethernet
ports (8-pin RJ45) and the other end of the cable to the Ethernet network. If the cable is properly connected,
the DA-660/662 will indicate a valid connection to the Ethernet in the following ways:
The lower right corner LED indicator in the lower right corner
glows a solid green color when the cable is properly
connected to a 100 Mbps Ethernet network. The LED will
flicker when Ethernet packets are being transmitted or
received.

The lower left corner LED indicator glows a
solid orange color
when the cable is properly connected to a 10 Mbps Ethernet
network. The LED will flicker when Ethernet packets are
being transmitted or received.
Connecting to a Serial Device
Use properly wired serial cables to connect the DA-660/662 to serial devices. The DA-660/662’s serial ports (P1
to P16) use 8-pin RJ45 connectors. The ports can be configured by software for RS-232, RS-422, or 2-wire
RS-485. The pin assignments are shown in the following table:
Pin RS-232 RS-422 RS-485
1 DSR --- ---
2 RTS TXD+ ---
3 GND GND GND
4 TXD TXD- ---
5 RXD RXD+ Data+
6 DCD RXD- Data-
7 CTS --- ---
8 DTR --- ---
Connecting to the Console Port
The DA-660/662’s console port is an 8-pin RJ45 RS-232 port. The port can be used to connect to the console
utility from a remote console via a V90 or GPRS modem with PPP protocol. The pin definition is the same as for
the serial ports (P1 to P16). For normal data acquisition applications, you should connect to the DA-660/662’s
serial ports (P1 to P16) via a V90 or GPRS modem. If you would like to use the console port for normal data
acquisition applications, you can set the console port to start up via PPP protocol.
USB Host
The DA-662 offers 2 USB 2.0 hosts, allowing you to connect with a USB storage device. The first USB mass
storage device to be connected will be mounted automatically by mount to /mnt/sda, and the second device
