TECHNICAL SUPPORT 

 

Commtech  provides  extensive  technical  support  and  application  suggestions.    Most  of  the  problems  that  occur 
with  the  FASTCOM:  422/4-PCI-335  can  be  corrected  by  double-checking  the  switch  positions,  your  cables  and 
your program.  We recommend that you build the loop back plug that is described in the Programming section of 
this manual.  With that plug, you can quickly isolate the problem to the board, cables, or software. 
 
If you still have unresolved questions, use the following procedure to get technical support: 
 
1.  Call our Technical Support Staff at (316) 636-1131.  They are on duty from 9:00 AM to 5:00 PM Central Time. 

2.  Ask  for  technical  support  for  the  FASTCOM:  422/4-PCI-335.    Be  ready  to  describe  the  problem,  your 

computer system, your application, and your software. 

3.  If necessary, our staff will give you an RMA number (Return Material Authorization).  Use this number on the 

mailing label and in all references to your board.  Put the board back in its static bag and in its box.  Ship the 
board back to us as directed. 

4. 

If you prefer, you may FAX a description of the problem to us at (316) 636-1163, or we can be reached on the 
Internet  at
