User Connections
The user connects to the DX-4400 product using the RS-232 Control port, the USB Serial Port or through a raw
TCP/IP connection via the Ethernet port.. For more information on using these interfaces refer to Section
External Control of the DX-4400
The raw TCP/IP connection is always available for external user control through Ethernet. For Serial Control, the
factory default connection is sets Serial Control to the RS-232 Control Port interface. To switch Serial Control to
the USB Serial Port requires the user to establish a connection to the Command Port (via either Telnet or through
the DB9 Serial port) and issue a Set Mode command to the unit per
Table 6: Set Mode Command Syntax
2.3.1 RS-232 Control Port
The RS-232 Control Port can be used to connect the DX-4400 to a computer to allow external control of text and
graphics overlay. For Serial Control, the factory default connection assigns the Serial Command Port to the
RS-232 Control Port interface.
A USB to DB9 RS-232 Serial Port Male-Male Adapter Kit (see Appendix B) is supplied to connect to the DB9
RS232 Serial port to a USB port on a PC. For more information refer to
2.3.2 USB Serial Port
The USB Serial Control Port can also be used to control the text overlay. It is a USB mini-B connector and has an
integral serial port set at 115,200 baud operation (8,N,1) and no flow control. The port interfaces to a PC with a
standard USB 2.0
– A to Mini-B (Male-Male) cable. Refer to section
External Control of the DX-4400
information on the use of this port.
2.3.3 Ethernet Port
A user can control the DX-4400 over Ethernet via:
•
a TCP Telnet client IP connection (using a Terminal Emulator) to the internal Command Port, (Refer to §
3.6.3.2 Default Static Network IP Address
•
a TCP SSH connection to the Linux (Root) User port, or
•
a TCP browser Web UI connection to the DX-4400 integrated web server. (Refer to §
The TCP Telnet connection is always available for use by the external user in addition to the Serial port
connection.
The RJ45 Ethernet port is a standard 10Base-T interface supporting data rates of 10/100Mbps and 1Gbps.
Note:
The default static IP address is discussed in §
3.6.3.2 Default Static Network IP Address
