TROUBLESHOOTING 

 
If you encounter problems, review each of the following items and take corrective action as described.  If 
problems persist, contact Xantech Technical Support. 
 

PROBLEM 

PROBABLE CAUSE AND SOLUTION 

The MX88, after a successful Transfer from Universal 
Dragon, will not send out any IR commands.   
 
A corrupted or incorrectly learned IR code has been 
transferred to the keypad. 
 

a)  Open all palettes that you used for the project. 

Click Edit Palette, on the first palette. When 
Palette Editor opens, retest each IR command to 
see that they operate the controlled equipment. 

b)  Close the Palette Editor and click Edit Palette on 

the next palette.  Repeat this procedure for each 
palette. 

c)  When you find the defective command "re-teach" 

it again using the Learning IR Commands 
procedure. 

d)  Before going further, test the relearned command 

to see that it operates the controlled equipment.  

e)  In the Palette Editor, right click the defective 

command on the right and delete it from the 
associated  palette. 

f)  Place the corrected command in the palette using 

the Add >> function. 

g)  Close the Palette Editor and open the palette. 
h)  Click the button on the virtual keypad that has the 

bad command and remove the command with a 
right click. 

i)  Place the corrected command on the keypad 

button by clicking it on the palette.  

j)  Redo the Transfer procedure. 
 
CAUTION: Always test all commands before 
transferring to the MX88! 

I have made hardware connections as shown in 

Figure 6 

or 7

.  However, when attempting to learn IR commands, 

the "Waiting for IR from your Remote" display times out 
with the "No IR Recorded" dialog box. 
 
Your computer is not recognizing or finding the serial port 
connection to the MX88. 

Try the following in the order listed: 
a)  The default serial port selection (1) in Dragon 

Drop may already be in use by another device in 
your computer system (such as a mouse). Refer 
to SERIAL PORT SELECTION, page 36, and 
perform the procedure listed there and in the 
following section VERIFYING COM PORT 
COMMUNICATION. 

b)  Check and replace, if necessary, the connecting 

cables and the DB9-to-DB25 adaptor. 

c) 

The serial COM port settings, such as port 

addressing and IRQ parameters, may not be set 
correctly in Windows.
