2.3.1 DS3 Connectors
The DSX-3 network interfaces are full-duplex circuits provided by two BNC coaxial cable connections. The
receive data from the network is connected to the Rx (Input) connectors; while the transmit data from the
T3Mux is connected to the Tx (Output) connectors.
2.3.2 Power Connection
The T3Mux is provided with a universal AC/DC 5V, 2A, center positive power adapter.
2.3.3 DS3 Status LED
A Green LED indicates the DS3 is Operational (no Alarms).
A Red LED indicates the DS3 is non-Operational (there are Alarms).
For a description of the Alarms, please refer to Section
3.3.1

2.3.4 ETH Port
The ETH Port is an 8-pin RJ45 connector that provides 10/100 Base-T Ethernet LAN Interface. This LAN
interface is used for Telnet control, using IP. The IP Configuration is described in details in Section 3.1.
2.3.5 RS232 Port
The RS232 port is a DB9 female connector, requiring a straight through cable, not null modem.
•
Baud rate 115200, 8 data bits, 1 stop bit, no flow control.
•
The RS232 port is used for Terminal Connection.
•
The Serial connection is established using a COM Port on the host PC.
We use the term “host” to refer to the Windows computer and “target” to refer to the T3Mux equipment.
Please note that the COM Port is not available on some systems. The alternative is “USB-to-Serial” converter
cable, similar to “Diablotek CA-1638 USB 2.0 to 9-Pin RS232 DB9 Serial Adapter - 2FT”.
If a COM port is available on your system, please use COM1 for Serial connection. If you are using a “USB to
Serial” converter cable to connect serial cable, please use COM3. If none of the above situation, you need use
the correct COM port that the host is connecting to T3Mux.
The next step is to set configuration of the COM Port in the Windows Device Manager:
In the COM1 (or COM3, or other port) Properties window, choose 9600 for the Bits per second. Choose 8 for
Data bits. Choose None for Parity. Choose 1 for Stop bits, and None for Flow control. Then click OK;
