1.    Plug in the Digi One Single Port power supply.

2.    Using a null modem serial cable with two DB9 female ends, hook up the Digi One Single Port to one of your PC's standard com ports.

3.    Download TTY.EXE from the following link:  http://ftp.digi.com/support/utilities/win2k-xp/index.html

4.    Execute TTY.EXE after downloading it(see Figure 1).
      
                                                                                                                                                                                          
Figure 1

5.    Click on Settings (see Figure 2).
      
                                                                                   Figure 2

6.    Select the standard com port you have your TCP Server hooked up to (see Figure 3).
      
                                                                                   Figure 3

7.    The COM Options should be set to 9600 baud, 8 data bits, 1 stop bit and No parity.  Make sure to uncheck the flow control options so none
       are selected (see Figure 4).  Click OK.
      
                                                                                   Figure 4

8.    Go to Action and click Connect.

9.    Power-cycle the Digi One Single Port.  Immediately hold down the Shift and press the "+" sign three times while the diagnostics light is flashing 
       on the Digi One Single Port unit.  You should get the following prompt (see Figure 5).
      
                                                                                                                                                                         Figure 5                                          

10.  Using the conversion sheet or the Microsoft Scientific Calculator, enter the port settings in Hexadecimal format.  You will have a 6 digit 
       number for Speed, Bits, Flow Control, Parity, Stop, and Timeout (see Figure 6).  Reference the worksheet you received with the product 
       for instructions on how to enter the information (Speed,Bits, Flow Control, Parity, Stop Bits and Timeout).  For example if you are using
       9600, 8, No Flow Control, No Parity, 1 Stop Bit and a 168ms Timeout, it would be entered as 530007.  Press Enter when finished.
      
                                                                                                                                                                                          Figure 6

11.  Now enter the IP Address in Hexadecimal format with no dashes or spaces.  For example, 199 would be C7 (see Figure 7).  Press Enter
       when finished.
      
                                                                                                                                                                                          Figure 7

12.  Enter the TCP Port number which the TCP Server will be listening on in Hexadecimal format using 4 digits.  This can be anything from 1 to
       65535.  For example, 2000 is 07d0 in hexadecimal and 23 is 0017 in hexadecimal (see Figure 8).  Press Enter when finished.  
       The Digi One Single Port will automatically reboot.
      
                                                                                                                                                                                         Figure 8
       
13.  Your TCP Server has now been configured and you should be able to ping it.  If you receive an >ER message at any point, you have entered
       an invalid number and will have to power-cycle the Digi One Single Port and start all over with S>.

14.  Once you have the TCP Server Configured, you can step through the TCP Client Configuration.
