Connecting to the Network
Connect one end of the Ethernet cable to one of the ThinkCore DA-660’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 will indicate a valid connection to the Ethernet in the following ways:
18
The lower right corner LED indicator glows a
solid green color when the cable is properly
connected to a 100 Mbps Ethernet network. The
LED will flash on and off when Ethernet packets
are being transmitted or received.
18
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 flash on and off when Ethernet packets
are being transmitted or received.

Connecting to a Serial Device
Use properly wired serial cables to connect the ThinkCore DA-660 to serial devices. The
DA-660’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 precise pin assignments are shown in the
following table:

Connecting to the Console Port
The ThinkCore’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 DA-660’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.
