b) Under Ports note the port number assigned to the "Prolific USB-to-Serial Comm Port". For example,
COMx when x is from 1 to 14.
Note: StarTech has also supplied a program called checkChipVersion_v1006.exe which can also
be used to
identify the Serial port.
Caution: If the USB Serial Adapter is moved to a different port on the PC, the OS will assign it a new COM port
number requiring a change to the Terminal Emulation port assignment.
4) Download and install a Terminal Emulator program to facilitate Serial communion of user commands to the
Command Port of the DX-4400. For example, PuTTY. (Available from:

)
B.2 Establishing RS-232 Serial Communication to a PC
By default, the Serial Command Port is assigned to the DB9 RS-232 Control Port (instead of the USB Serial Port).
As the Serial Command Port can be assigned to either the RS-232 Control port or to the USB Serial Port, if the
factory default setting for the Serial Control Port has been changed to the USB port, it is necessary to make either
a USB connection or a TCP/IP connection to issue the necessary command to reassign Serial control to the RS-
232 Port prior to connecting to a PC. Since the TCP/IP connection is always available, establish a TCP/IP telnet
client connection and use the Commands in
Table 6: Set Mode Command Syntax to select the RS232 mode.
For example, if the unit is to be operated in the PIP Mode, the command 'SM PIP RS232 ' sets the unit to PIP
mode with the Serial Command Port on the DB9 connector..
1) Run the PuTTY program.
TIP: It is convenient to place a shortcut link on the desktop to the PuTTY software application.
2) Configure PuTTY as follows:
a) Under Category, select the Session item:
i) For Connection type select Serial >> enter the assigned Port i.e. COM3
ii) Set Speed to 115200.
iii) For Connection type: >> select Serial
iv) Under Saved Session: Assign a name to this user setting. i.e. DX-4400 Serial
v) Save the configuration.
b) Under Category, select the Terminal item.
i) Additionally, check the boxes for:
(1) Implicit CR in every LF and for
(2) Implicit LF in every CR.
c) Under Category, select the Serial item.
i) Set the Serial line to the required come port i.e. COM3
ii) Set the Speed to: 115200, Data bits to: 8, Stop bit to: 1, Parity to: None, and Flow Control to: None.
d) Select the Session item again and re-save the configuration to DX-4400 Serial.
NOTE: Going forward when restarting PuTTY, it is only necessary to select the DX-4400 Serial
configuration and "Load" it from disk.
e) Connect the USB Adapter to the DB9 Serial cable and attach the male DB9 connector to the Serial port of
the DX-4400 unit.
f) In the Session section,
i) Confirm the DX-4400 Serial configuration is selected and then click Load.
ii) Click "Open" to a establish a Terminal connection to the unit via the serial port.
iii) Type the "ENTER" to get an * response from the unit.
