4) Web UI Control using a standard web browser and a TCP Ethernet connection. This method of control is
discussed in section (§) 5 titled Using the Web UI .
To utilize Serial Control requires the user establish a connection via either the RS232 port or the USB Serial port.
The factory default connection sets Serial Control to the RS-232 Control Port interface.
To switch Serial Control from the RS-232 Control Port to the USB Serial Port requires the user to establish a
connection to the internal Command Port (via either Network Control port or through the DB9 Serial port) and
issue a Set Mode Command to the unit per Table 6: Set Mode Command Syntax.
Alternately, the user can use Network Control via a TCP/IP connection to the Command Port since it is always
available for external user control through a TCP Ethernet connection.
Note: For the examples provided in the following sections, the Commands are executed via a Serial (RS232
or USB) connection or a Network TCP/IP connection to the Control Port of DX-4400 unit.
Warning: Only one Network Control port user connection can be active at a time.
3.6.1 Serial Control Mode of Operation
When Serial Control is used, the DX-4400 is controlled via Commands sent to the Command Port via either the
RS-232 Serial Control Port or the USB Serial Port using a terminal emulator program on a PC. Refer to
Appendix B , section Establishing RS-232 Serial Communication to a PC page 100 for the recommended settings
for the PuTTY terminal emulator.
Note: The Serial COM port of the computer connected to the DX-4400 should be configured for: 115,200
baud, 8-bit data, no parity, 1 stop bit and no XON/XOFF flow control.
The Command Port acknowledgement codes (supplied from the DX-4400 and received by the PC) are listed in
Table 2 below.
3.6.1.1 USB 2.0 to RS-232 Serial Port Adapter Kit
Since most PC no longer come with a RS-232 Serial port, the DX-4400 product is supplied with a USB 2.0 to
DB9 RS-232 Serial Port Adapter Kit (PN: 811-USB-RS232 Kit) to connect the DB9F Serial Port on the unit to a
USB 2.0 port of a PC or laptop. The Kit consists of a USB 2.0 to RS232 DB9 Serial Adapter Cable (StarTech PN:
ICUSB232V2) and a 6 foot male to female DB9 RS232 Serial cable. Refer to
Appendix B titled Establishing
User Connections to the DX-4400 Product for more information.
3.6.1.2 USB Serial Port
The USB Serial Control Port can also be used to control the text overlay. The port interfaces to a PC with a
standard USB 2.0
– A to Mini-B (Male-Male) cable included with the product.
Since by default, the Serial Control Port is mapped to the RS-232 Serial port, to use the USB interface it is
necessary to establish a connection to the Command Port (via either Network Control port or through the DB9
Serial port) and issue a Set Mode command to the unit per
Table 6: Set Mode Command Syntax to switch Serial
Control to the USB Serial Port. \
3.6.2 Network Control Using Raw TC/IP
The Network Control connection is used to sent commands to the DX-4400 over Ethernet, using a terminal
emulator (Telnet, PuTTY) application to TCP port number 2121. The Ethernet address is either assigned via
DHCP or by static IP address assignment (default 10.1.1.230/8)
From either a Windows command prompt or Linux command line, you can establish a Network Control user
connection to the Command Port of the DX-4400 using the following commands:
